This study investigated medical students' perceptions of good jobs. We classified medical students' perceptions of good jobs and analyzed the characteristics of each type. The Q methodology was used to extract medical students' subjective thoughts. After extracting statements based on previous studies, 46 Q samples were selected. The P sample consisted of 40 medical students divided evenly by gender and grade. They performed a Q sort of the 46 Q sample questionnaire and the results were analyzed using the QUANL ver. 1.2 program. Very few consensus statements were found in the replies. We divided answers into four types, each of which was clearly distinguished: (1) quality of life-oriented jobs, (2) reward-oriented jobs, (3) service-oriented jobs, and (4) self-realization-oriented jobs. Medical students in type 1 prioritized quality of life equally at work and at home. Medical students in type 2 preferred high-paying jobs. Medical students in type 3 placed importance on serving others. Finally, medical students in type 4 viewed good jobs as involving learning and development. The types of jobs sought were classified according to individual students' values and subjectivity. Medical schools may use the results of this study as a basis for career guidance.

Purpose: This study was performed for the effective management of nursing organization as surveyed choice motives and job satisfaction about nurses who changed to public hospitals. Methods: This study is a descriptive study. This study surveyed 214 nurses who changed jobs to public hospital in six Gyeonggi-do hospitals from October 23 to November 20, 2015. The collected data were analyzed for descriptive statistics, t-test, one-way ANOVA, sheffe test, multiple linear regression analysis using the SPSS/WIN 21.0 program. Results: Most of the nurses chose public hospitals due to benefits correspond to public officials. They had worked in general hospitals located on provinces and changed jobs due to a heavy workload and low benefits. Of the participants 84.1% were satisfied with changing jobs to public hospitals and the advantages of public hospitals of their choice were job stability and good employee benefits(guaranteed maternity and paternity leave, etc). On the other hand there were complaints about low salaries compared to the workload after changing jobs to public hospitals. Conclusion: Hospitals need to enhance job stability and provide nurses with good employee benefits to reduce turnover rate.

In parallel job scheduling, each job can be executed simultaneously on multiple machines at a time. Thus in the input instance, a job $J_i$ requires the number $m_i$ of machines on which it shall be processed. The algorithm should determine not only the execution order of jobs but also the machines on which the jobs are executed. In this paper, when the jobs have deadlines, the problem is to maximize the total work of jobs which is completed by their deadlines. The problem is known to be strongly NP-hard [5] and we investigate the approximation algorithms for the problem. We consider a model in which the algorithm can have more machines than the adversary. With this advantage, the problem is how good solution the algorithm can produce against the optimal algorithm.

In this paper, we present a restricted tabu search(RTS) algorithm that schedules jobs on identical parallel machines in order to minimize the maximum lateness of jobs. Jobs have release times and due dates. Also, sequence-dependent setup times exist between jobs. The RTS algorithm consists of two main parts. The first part is the MATCS(Modified Apparent Tardiness Cost with Setups) rule that provides an efficient initial schedule for the RTS. The second part is a search heuristic that employs a restricted neighborhood generation scheme with the elimination of non-efficient job moves in finding the best neighborhood schedule. The search heuristic reduces the tabu search effort greatly while obtaining the final schedules of good quality. The experimental results show that the proposed algorithm gives better solutions quickly than the existing heuristic algorithms such as the RHP(Rolling Horizon Procedure) heuristic, the basic tabu search, and simulated annealing.

The problem of minimizing total tardiness on a batch processing machine with incompatible job families when there are sequence independent setup times between families is studied where all jobs of the same family have identical processing times and jobs of different families cannot be processed together. A batch processing machine can process a number of jobs, within a maximal batch size, simultaneously as a batch. The processing time required of each batch is equal to the one of jobs. A dynamic programming algorithm which gives the optimal solution, and several heuristics are presented. Performance of simple dispatching rules based on due dates are compared, and the best of them is used as an initial solution for the decomposition algorithm, which is shown to give good schedules in relatively short computational time.

This study examines attitudes among nursing student, attitudes that give direction in life and effect the decision-making process when seeking employment. The exigency of which derives from the need to design a proper guidance program to assist students in their search for employment. Data was collected from a survey conducted between November 20 and November 25, 1995, the respondants of which were 120 nursing students without jobs. The data was analyzed by examining frequency, percentage, average, Chi-square, one-way ANOVA and t-test through an SPSS $PC^+$ program. The results of the study can be summarized as follows : 1) There are positive relationship between a student's academic major and employment(So responded 84.3% of the subjects with only 2.5% claiming that his major didn't matter). 2) Students believe that 'good jobs' are secured through aptitude. 'Good jobs' are seen as ones which develop an individuals abilities and which offer the opportunity for advancement. However they do not believe that 'good Jobs' contribute to society 3) Students have not been supplied the proper guidance and information necessary for finding employment. The student's life research institude, professor and assistants provide Insufficient information and counseling. Personal goals are decisive factors in determining what direction a student may take as well as the kind of employment he will seek. However, advice from parents, siblings, friends, alumni, professors, assistants and counselors is also considered. 4) Students do not think it reasonable to base their career decisions on one factor only(33.9% responded that aptitude and personal interests were the most important factor, and 14.9% that income was the key determinant). 5) Location and size of the hospital are important considerations when choosing a job. There is a preference for larger hospitals. 6) A lack of stability and few opportunities for advancement are perceived as the primary reasons for the possibility of leaving one's job.

자동화 컨테이너 터미널의 장치장은 수출입 되기 전의 컨테이너를 임시로 보관하는 장소이다. 모든 컨테이너는 반드시 장치장을 거치기 때문에 효율적인 장치장 운영은 터미널 생산성 향상에 큰 영향을 미친다. 효율적인 장치장 운영을 위해서 컨테이너의 위치 선정은 매우 중요하며 보통 컨테이너의 적재 위치는 컨테이너가 장치장으로 들어올 때 정해진다. 하지만 컨테이너가 처음에 최적의 장치 위치로 적재 되었더라도 시간이 흐름에 따라 최적의 위치가 달라질 수 있다. 이에 대부분 터미널에서는 컨테이너를 좋은 위치로 재배치하는 재정돈을 수행하고 있다. 기존 연구에서 재정돈에 관한 여러 가지 방안이 제시되었지만 모두 본 작업이 없는 크레인 유휴 시간을 이용하는 것을 전제로 하여 현실적으로 적용에 제약이 있었다. 본 논문에서는 본 작업 중에 언제라도 기회가 있을 때마다 재정돈을 수행할 수 있는 크레인 작업 할당 방안을 제안한다. 시뮬레이션을 통한 실험 결과 제안 방안이 터미널 생산성 향상에 효과적으로 기여함을 확인하였다.

일정계획은 오프라인(offline) 일정계획과 온라인(online) 일정계획으로 구분할 수 있고, 본 논문은 온라인 상황에서 병렬설비의 주기적 일정계획 수립문제를 다룬다. 도착시간(ready time)이 다른 여러 작업들에 대해 makespan을 최소화하기 위한 작업 일정계획 알고리즘 개발이 목적이다. 이를 위해 각 설비에서의 작업처리 순서는 ERD(Earliest Ready Date) 규칙에 따른 순서가 최적임을 밝혔다. 각 설비 별 배정 작업도 결정 해야하는 병렬설비 문제를 위해서는 혼합정수계획모형(MIP)을 이용하는 알고리즘을 제시하였다. 개발한 알고리즘의 유용성과 성능분석을 위해 수치 예를 활용하여 오프라인 일정계획과 비교하였다. 비교분석 결과, 오프라인 일정계획에 비해 매우 빠른 시간에 일정계획을 수립할 수 있음을 보였고, 주기시간의 감소를 통한 makespan의 단축 가능성을 보였다. 본 논문의 주기적 일정계획 방법은 계획수립을 위한 시간이 매우 작으므로, 설비 및 작업의 수가 많은 온라인 환경에서도 활용할 수 있다. 더불어서 스마트공장이나 블록체인 플랫폼에서의 작업일정 수행을 위해 활용될 수 있을 것으로 기대한다.
