Being in era of the digital economy, the influence of IT that effects on our economy is getting greater. Along with this effect, IT becomes origin of predominance of competition in every category of industry. Regarding new trends in industry, how companies mutate their IT skill become important factor. Every industry has their own color and environment of IT and uncertainty is different. For a company, It is most important to plan own strategy with strategic view on industrial environment. The idea of this study is to find the difference of Skill Requirement and Job Requirement in every category of industry by find what are the most important jobs and skills of IT in every industry and to analyze the results. The second idea is to find what kinds of skill are required in every sector of job. Base on the analyzed data, we classified the uncertainty in every industry by Duncan′s "classification of environment", and extracted some pattern within the skill and job in industry that found in our study by applying OIP model. We set skills by categorized curriculum of specialized IT education center, then with IT specialist, checked and retouched the results and surveyed with IT people in every industry on skill set and job of IT. The summery of this study is as follow : 1. Importance of IT skill is differentiated in each industry. It shows that IT skills, which requested in a field are differentiated by uncertainty of environment that comes from the character of industry. 2. Importance of IT job differs by the fields of industry. It shows as IT skills are differentiated, the importance of job that apply these skills is differentiated. 3. As the character of each job that work on is diversified, the importance of skills are diversified in each field of jobs. The Result of this study can give the idea to who designs curriculum and builds educational contentsthat would fulfill the need of fields. Also this study would be meaningful that it opens the field of study of skill requirement in Korea.

The impact of supervisory communication apprehension (SCA) on subordinates' job performance was investigated in this study. We also examined the impact of task-related uncertainty in mediating the relationship between SCA and subordinate work performance, as well as the role of information-seeking behavior in moderating the relationship between task-related uncertainty and subordinate job performance. A sample of subordinates and their supervisors from public and private sector enterprises in Pakistan were used in the study. The concept of communication apprehension is not limited to a single organization or industry, and the conditions suggest that apprehensive supervisors are likely to exist in different organizations and industries in Pakistan, including banks, telecommunications, and development sector organizations. Company directors and leaders of human resources departments were contacted to reach out to possible respondents. SmartPLS software was used to evaluate the data using a structural equation modeling technique which is commonly used in explanatory studies (Atta et al., 2021). We found evidence to support ideas predicting the association between SCA and subordinate job performance, as well as the mediating role of task-related ambiguity in the relationship. Furthermore, the findings show that information-seeking activity has a moderating effect on the link between task-related ambiguity and subordinate job performance. This is one of the first studies to look at major mediating and moderating mechanisms in the link between SCA and subordinate job performance.

In this study, a multi-objective robust job-shop scheduling (JSS) model was developed. The model considered multi-jobs and multi-machines. The model also considered uncertain processing times for all tasks. Each job was assigned a specific due date and a tardiness penalty to be paid if the job was not delivered on time. If any job was completed early, holding expenses would be assigned. In addition, the model added idling penalties to accommodate the idling of machines while waiting for jobs. The problem assigned was to determine the optimal start times for each task that would minimize the expected penalties. A numerical problem was solved to minimize both the makespan and the total penalties, and a comparison was made between the results. Analysis of the results produced a prescription for optimizing penalties that is important to be accounted for in conjunction with uncertainties in the job-shop scheduling problem (JSSP).

This paper investigates how small-medium firms deploy organizational culture, job stability and environmental uncertainty for technological innovation(product and process innovation). This paper suggests that organizational culture has significant effects on technological innovation, that job stability and environmental uncertainty moderate relationship between organizational culture and technological innovation. To test the hypotheses, data were collected from small-medium firms. The survey data of 258 firms were collected and integrated as the empirical base for testing the hypotheses. Major results are as follows: Firstly, when organizational culture as well as control variables are considered, organizational culture had significant and positive effects on product innovation. This result implies that organizational culture is an important means by which small-medium firms can promote innovation. Secondly, the interaction between organizational culture and job stability had a positive and significant effects on product innovation. Thirdly, the interaction between organizational culture and environmental uncertainty had a positive and significant effects on product innovation and process innovation. This paper suggests implications and several future researches need to overcome the limitations of this paper.

Purpose: This study was conducted to investigate the correlation between uncertainty and depression in hospitalized children's mothers. Methods: The subjects were 175 mothers of children who were hospitalized in pediatric unit. A self report questionnaires were used to measure the variables. Variables were uncertainty and depression. In data analysis, SPSSWIN 20.0 program was utilized for descriptive statistics, ANOVA, Pearson's correlation coefficients and multiple regression. Results: Reliability of instruments were found cronbach's alpha=.85~.86. Uncertainty correlated positively with depression(r=.422, p<.010). There were significant differences in depression according to birth order(F=6.58, p=.002), mothers' age(F=6.57, p=.002), education level(F=3.97, p=.021) and mothers' job(t=19.18, p<.001), monthly income(F=4.234, p=.006) and family type(t=7.49, p=.007). In multiple regression, uncertainty, mothers' job and family type were significant predictors of depression in hospitalized children's mothers explaining 30.9%. Conclusions: Uncertainty and depression were significant variables in hospitalized children's mothers. The strategy of nursing intervention which decrease depression in mothers must be developed by decreasing level of uncertainty in mothers of hospitalized children.

The purpose of this study is to provide the developmental basic data of a change in shift work types by making a self-administered survey of the effect of commitment by shift work and the open kitchen system on job satisfaction and job stress, and mutual relation between variables on 287 cooks in luxury hotels. Analysis showed that the operation of the shift work system was effective in reducing the internal stress of the cooks, their external stress, or their self-uncertainty on the job, and the business by the open kitchen system was effective in raising self-esteem. In addition, job commitment by shift work and the open kitchen system were effective in promoting the job satisfaction of employees, interpersonal relations, promotion, benefits and wages. Consequently, the decrease of external and internal stress or self-uncertainty and the improvement of job satisfaction can be connected with the increase of productivity or cost reduction. Therefore, the open kitchen system should be properly applied to the shift work system, along with sanitation, safety and the periodic checkup of kitchen.

Purpose: The purpose of this study was to understand how disease activity and uncertainty influence anxiety and depression in patients with ankylosing spondylitis Methods: Participants were 125 patients with ankylosing spondylitis who had attended the rheumatology division of a university hospital. A structured questionnaire was used to assess disease activity, uncertainty, anxiety, and depression. The data gathered were analyzed using t-tests, ANOVAs, Pearson correlation coefficients, and a multiple regression. Results: Differences were observed in anxiety based on job status, and in depression based on age, marriage, and job status. Uncertainty and disease activity predicted patients' anxiety and explained 40% of the variance in this measure, and the relative influence of uncertainty (${\beta}=.38$, p<.001) was larger than that of disease activity (${\beta}=.30$, p<.001). Furthermore, uncertainty and disease activity predicted depression and explained 36% of the variance therein, and the relative influence of uncertainty (${\beta}=.27$, p=.002) and disease activity (${\beta}=.27$, p=.003) was similar. Conclusion: This study confirmed that disease activity and uncertainty influenced anxiety and depression in patients with ankylosing spondylitis. Therefore, efforts to decrease anxiety and depression in patients with this condition must take into consideration disease activity when implementing nursing interventions and should include strategies to lower uncertainty.

Purpose. The purpose of the study was to categorize nursing students' subjectivity in their attitude toward their jobs, and thereby understand the differences among these attitude types. Methods. The study used a Q-method to measure nursing students' attitude toward jobs identity types. In-depth and objective interviews and literature review formed Q sample. The P sample consisted of 25 nursing students. Results. The results of the study show that nursing students can be categorized into three types, depending on their attitudes toward their jobs. The firs type, 'interest-oriented' students, strongly disagree to the follow-ing: giving priority to job over marriage, standing unfair treatment in the workplace, the importance of pro-motion opportunity, irresponsibility, and uncertainty. The 'reward-oriented' students, on the other hand, strongly disagree to the following: indifference to career prospects, employment-related relocation of residence, irresponsibility, standing difficulties, and compromises with others. The third type of nursing students is the possession-oriented students, who strongly disapprove of irresponsibility, refusal to compromise with reality, standing unfair job allocation or promotion and career uncertainty. Conclusions. The study on nursing college students' attitude toward their jobs is meaningful in the following aspects: First, the study clarifies nursing college students' attitudes toward their job by categorizing it. Second, the study confirms the changing attitudes of nursing students toward jobs with the change of times and calls for proper educational programs to foster healthy career attitudes. Third, proper decision-making as regards jobs and job allocation for nurses, or their career attitudes, is beneficial to individuals, the medical industry, and society.

The core competencies such as technology have been rapidly developing with advent of the fourth industrial revolution. One of the representative technologies in the era of the 4th Industrial Revolution is artificial intelligence(AI). In particular, AI makes human life richer and more comfortable and has many positive aspects. The negative aspect is that AI is likely to replace the organizational members' job and has the ability to replace skills associated with it. These threats may increase the level of perception that organizational members may loss their job. Moreover, it may lead to a sense of anxiety. In addition, organizational members who perceive job uncertainty highly, the job substitution anxiety may be become highly. According to this, their job satisfaction can be lower. Overall, this research emphasized the negative aspects of AI in contrast to the positive aspects of the fourth industrial era. It is also emphasized that the organization should need to recognize such problems and seek solutions to reduce workers' anxiety. Finally, practical implications and research directions of future study were presented through the research results.
