Introduction
Organizational citizenship behavior becomes one of the significant factors that enhance the organizational effectiveness to achieve the organizational goal. Organizational behavior is as a discipline that attempted to clarify human behavior and reasons for various kinds of behaviors in an organization [1]. Organizational citizenship behaviors have been defined as behaviors that an employee voluntarily engages in activities to promote the effectiveness but are not clearly rewarded by the organization [2]. "Podsakoff, MacKenzie and Organ [3] defined organizational citizenship behavior as individual behavior that is discretionary, not directly or clearly recognized by the formal reward system, in order to promote the efficient and effective functioning of the organization".
Organizational citizenship behavior increases the preference towards helping and sharing information, and promoting the feeling of responsibility, motivation, and satisfaction within the organization. For these grounds, work quality and patient satisfaction can increase organizational citizenship behavior by precise communication and cooperation for establishing strong relationship with health staff, managers, and workers. Nurses who are the most active members, they should display efficient health services activities to provide high levels of organizational citizenship behavior related goals [4].
Organizational citizenship behavior is to protect the organization against disparaging and an undesirable behavior, which protects the organization's healthy operations, improves incumbents' skills and abilities and increases performance and productivity of organization by efficient co-ordination. More productivity and profitability is the result of organizational citizenship behavior in healthier organizational outcomes. Organizational citizenship behavior helps to make best use of organizational performance of hospital. The two major components of organizational citizenship behavior are compliance, which indicates employees' intention to follow the organizational rules, and altruism, which means employees' voluntary behaviors to assist others and to work [5].
Organizational commitment is the employees' state of being committed to assist in the accomplishment of the organization's goals, and involves the employees' levels of identification, involvement, and loyalty [6]. "Meyer and Allen [7] have identified three types of organizational commitment: affective, continuance, and normative". Organizational commitment plays a crucial role in determining whether an employee will stay with the organization for a longer period of time and work passionately towards achieving the organization's goal.
The issue of organizational commitment is very important for managers in organization to achieve the goal by effective activities. However organizational commitment toward behaviors is very beneficial for the organization because it reduces the absenteeism rate and turnover ratio and enhances the organizational productivity [9]. In order to increase the competitive advantage, the managers continuously seeking ways to enhance the employee's commitment. Organizational commitment, as an attitude, has been defined as the relative strength of an individual's identification with, and involvement in a specific organization [10].
Commitment phenomena are wide investigated for the reason that they influence individual approach and behaviors at the workplace. Occupational commitment has established to be distinguishable from alternative commitment measures like job involvement and organizational commitment, with minimal dismissal. Regarding organizational commitment, the three-dimensional definition acknowledges affective, continuance, and normative commitment as distinct concepts. The most widely investigated dimension of organizational commitment is affective commitment. Affective commitment defined as the degree to which an individual is emotionally involved to an employing organization through feelings such as loyalty, affection, belongingness, etc. Explanation of the employees' emotional bond or attachment is to an organization [11].
"Van-Scotter [12] had founded significant relationship between organizational citizenship behavior and affective commitment". Literature from "Steyrer, Schiffinger and Hang [13] reveals that organizational commitment not only makes an employee to stay in the organization but also make it possible for the employees to take part in organizational activities". However, in recent decades, organizational citizenship behaviors have emphasized greatly on organizational commitment aspect of employees and it is found to be the significantly correlated [14]. A different study illustrated that between organizational citizenship behavior and organizational commitment there was significant and positive correlation (r = 0.32, p-value < 0.05) [15].
"Moinul and Tahlil [16] conducted a study to know the effect of recognition practice over affective commitment and organizational citizenship behavior. Their study founded that recognition practice affects affective commitment and affective commitment affects 'organizational citizenship behavior' positively". "Ferdus and Kabir [17] study also showed that organizational citizenship behavior level of bankers in Bangladesh is high". "Nesa, Kunaviktikul and Wichaikhum [18] study shown that the level of overall organizational citizenship behavior was at a moderate level ( X = 54.92, SD = 1.57) in Bangladesh".

Purpose of the Study
The aim of the study was to explore the relationship between organizational citizenship behavior and organizational commitment among nurses at a medical college hospital in Bangladesh.

Methods
The descriptive correlational study design was conducted at Dhaka Medical College Hospital. The total numbers of 164 (estimated by using "G" power analysis) samples were recruited by simple random sampling technique. The instrument consisted of two parts including: The Demographic Data Questionnaire and organizational citizenship behavior & organizational commitment Questionnaire which was measured by 4-point Likert scale. Data was collected by structure self administered questionnaire. Two sample t-test, ANOVA and correlation were used for data analysis.

Ethical Consideration
Before the study, written ethical consent was obtained from the ethical boards and hospital. Moreover, all of the participants gave written consent prior to participating in the study.

Result
Analysis was performed on the data from 164 nurses'; the subjects age ranged from 24 to 57 years with mean of 34 The subjects service experience ranged from 2 to 37 years with a mean of 10.97 years and (SD = 8.45). 40 (24.4%) number of the subjects were working at surgery department and the rest of the subjects were working at others ward/department. About three forth of the subjects hadn't get any training 119 (72.6%) in the year 2018-2019. Response rate of the participants is 85.86% and the Cronbach's alpha coefficient of the questionnaires was 0.97. The level of organizational OCB but OC is moderate. Table 1 showed that there was a statistically significant relationship between organizational citizenship behavior with ward (F = 6.31, p = 0.000), whereas (3.28) CCU ward was a high level of (M = 3.28, SD = 0.35) behavior compare with others ward. Therefore, nurses had no significant relationship between organizational citizenship behavior with age, gender, religion, marital status, nursing education, service experience and training. Table 2 showed that there was a statistically strong significant relationship between organizational commitment with working ward (F = 4.45, p = 0.002), whereas nurses' who were working at CCU ward they had high level of organizational commitment (M = 3.31, SD = 0.46) compare with others ward. Therefore, nurses had no significant relationship between organizational commitment with age, gender, religion, marital status, nursing education, service experience and training.

Discussion
The proposition that younger and older employee may view work and self in fundamentally different ways is not new. "Wagner and Rush [19] pointed out that 35 -55 year are strong sense of self and work". In this study mean age of the respondent are 34.19 years and SD = 8.02, whereas "Jahangir, Akber and Haq [20] mention that younger employees coordinate their needs with organizational needs more flexibly". The majority of the subjects were female nurses' (87.2%).
In Bangladesh, more female (93%) nurses' are currently working in the hospitals, and this is similar to many other countries all over the world [21]. "Karimi and Alavi [22] [26] proved that graduate were more (M = 95.17, SD = 9.70) OCB than under graduate (M = 91.00, SD = 11.64).
The study findings showed that the total mean score of nurses' service experience was at a low level (M = 10.97, SD = 8.45). Last five year huge number of 19638 nurses recruited in Bangladesh they were need to developed their knowledge, attitude and commitments [27].
In Bangladeshi nurse ward placement system are not so good, nursing author- nurses provided bed side care [28]. This study results showed that (24.4%) number of nurses were working in surgery ward. The educational programs that have been developed within this collaboration the enhanced specialized nurse training program the Bangladeshi nurses have received continuing professional improvement based on Western standards of nursing [29]. The study results showed that majority of nurses wasn't got training in 2018-2019 year (72.6%).
Ortega et al., [30] demonstrate that 53.8% of nurses don't consider the training received to be relevant to the needs of the workplace. However training and education were directly linked to nurses' career satisfaction. Healthy work environments were identified by nurses as those that invested in continuing professional development opportunities to ensure continuous growth in their practice and provide optimal quality patient care [31].
The study findings showed that average mean score of organizational citizenship behavior was 3.03 (±0.45) and organizational commitment were 3.10 (±0.52). The findings of this study indicated that the nurses' had moderate level of OCB & OC. "Altuntaş [4] founded that Nurses were originate to display high levels of organizational citizenship behavior".
In addition, I showed that there was female nurses OCB & OC both are 3.05 (±0.46), 3.13 (±0.52) more than male 2.91 (±0.37), 2.93 (±0.47) other than there are no significant relation. Moreover, "Dargahi, Alirezaie and Shaham [33] founded that there was significant correlation between genders with nurses". However, a previous study also founded that male nurses are always facing different kind of problems in both government and private hospital settings. In Bangladesh male nurses are, disregard and discrimination compared with female nurses therefore, given less or denied attitude facilitated male nurses for mounting their career in highest level as well [33]. On the other hand "Terzi [34] be evidence for male teacher OCB & OC both are 4.76 (±0.85), 3.08 (±0.51) more than female 4.97 (±0.86), 2.92 (±0.51)".
Using by ANOVA methods I found that there was a positive significant relationship (F = 6.31, p = 000), (F = 4.45, p = 002) between working ward and OCB & OC. However, CCU ward nurses' was more OCB & OC 3.28 (±0.35), 3.31 (±0.46) than others ward. DMCH authorities should be observed this department very carefully. Thus, Alammar et al., [35] conclude that the characteristics of the work setting for nurses in the general ward or in a specialized unit do not have a significant impact on job involvement. "Israel et al., [36] proved that working ward (F = 7.72, p = 0.000) were significant predictors of organizational commitment among nurses and surgery ward was more 73.41 (±7.50) than others ward".
Moreover I demonstrate that highly experience (20 -37 years) nurses OCB & OC both were 3.05 (±0.46), 3.19 (±0.52) more than tiny experience (2 -19 years) nurses 3.03 (±0.45), 3.09 (±0.52). On the other hand "Terzi [34] mentioned that experienced teacher OCB was more and low experience teacher OC was more than experienced". DOI: 10.4236/ojn.2020.107049 700 Open Journal of Nursing "Noor [9] showed that the correlation value between training and development opportunities and organizational commitment is r = 0.351, p = 0.01 and the beta value is 0.124 which shows the significant relationship between the training & development opportunities and organizational commitment". In the study illustrated that education and training significantly (r = 0.36, p = 000) improve organizational commitment. I founded that significant correlation between work place satisfaction & OCB (r = 0.37, p = 000), whereas "Bishwajit, Khumyu and Boonyanurak [37] proved that a significant correlation between organizational commitment and job satisfaction (r = 0.32, p < 0.01)". In this study demonstrate that positive significant correlation between leader command & OC (r = 0.57, p = 000). On the other hand "Khan and Rashid [14] bear out significant correlation between leadership & OC (r = 0.52, p = 010)". Another study founded that significant correlation between team oriented & OC (r = 0.44, p = 000). In this study as well I founded that significant correlation between teamwork & OC (r = 0.44, p = 000) [13].
The results divulge that the organizational commitment and organizational citizenship behavior are very closely associated with each other. The correlation value between OCB and OC is (r = 0.82, p = 0.000). According to "Noor [9] found that there was a significant (r = 0.80, p = 0.01) relationship between organization citizenship behavior and organizational commitment. Another Bangladeshi study show that there was a significant (r = 0.23, p = 0.00) relationship between organization citizenship behavior and organizational commitment [17]". On the other hand "Khan and Rashid [14] showed that the correlation between organization commitment and organization citizenship behavior was positive and significant (r = 0.417, p < 0.01)". "Jafari, Sadeghi, and Zarnagh [15] founded that Between OCB and organizational commitment there was significant and positive correlation (r = 0.32, p-value < 0.05)". Although another researchers explained that there was a positive and significant relationship between organizational commitment and organizational citizenship behavior (r = 0.181, p = 0.040) [38].

Conclusions
The current study indicated that there was a positive significant relationship between organizational citizenship behavior and organizational commitment.
According to the findings, it is concluded that notice to OCB concept and its establishment in organizations can be useful in predicting some organizational concepts like organizational commitment and performance. Therefore, the nurses' Limitation of the study: Several limitations were inherent in the methodology used in this study.
Firstly, the sample was recruited from 5 departments and only one hospital in Bangladesh. Secondly, this study used a set of self administer questionnaire for data collection that may not reflect the actual data. Thirdly, due to limited study in Bangladesh it was difficult to comparison. Therefore, generalizations that can be made from the study are limited. Recommendation: Based on the results of this study, it is indicated that lack of OCB & OC among nurses' is moderate level. To improve the quality of nursing care, OCB & OC, the following implications and recommendations are offered.
Nursing training and education: The results of the study indicated that nurse's inadequate in-service training program may be the cause. Thus, it is recommended that the syllabus in Bangladesh Nursing Curriculum should be reviewed and added comprehensive program regarding OCB & OC, so that nursing students would be well-prepared before graduation. Up-to-date in-service training program will be able to provide new knowledge which help nurses' to enhance OCB & OC.
Nursing research: The findings from this study will provide a reference criterion for further stu-
