본 연구에서는 급증하는 배송 서비스 수요에 맞춰 더 신속하고 최저 비용으로 근거리 배송을 가능하게 하는 알고리즘을 제안하고자 한다. 본 연구에서 제안하는 알고리즘에서는 배송원으로 지하철 승객을 물류 이동에 참여시킨다. 이때 승객은 이동 경로와 일치하는 배송 물류를 선택할 수 있다. 그리고 서비스 이용자의 입장에서는 현재 근처에 경로가 일치하는 배송원을 선택할 수 있다. 이때 배송원 추천은 TF-IDF&N-gram과 BERT를 결합한 텍스트 유사도 측정 방식으로 진행된다. 따라서 기존 택배 시스템과 달리 소비자-배송원 간의 man-to-man 방식으로 양방향 선택을 지원한다. 탑승 중인 승객을 물류 이동에 참여시킨다는 점에서 비용 최소화와 배송 기간 단축을 모두 보장할 수 있다. 더하여 운송 측면에서도 특별한 기술을 요하지 않으므로, 일자리 입지가 축소된 노동자들에게 경제 참여 기회를 제공할 수 있다는 점에서도 의의가 있다.

본 연구는 "대졸자직업이동경로조사"를 활용하여 학자금 대출 경험이 있는 대학 졸업자의 노동시장 성과에 대해 살펴보고 있다. 특히 분석대상을 대학 졸업 이후 18개월간 경험하는 모든 일자리로 확장하고, 대출 경험자의 이질성을 고려하기 위하여 성향점수 매칭 방법을 사용하였다. 분석의 주요 결과는 다음과 같다. 첫째, 학자금 대출 경험자는 대출 미경험자와 비교하여 첫 일자리의 임금이 2.81% 낮았다. 둘째, 첫 일자리에서 관찰된 임금격차는 시간이 흐르며 감소하였으며, 특히 이직 및 재취업으로 인해 0.66%p의 축소가 이루어졌다. 셋째, 졸업 후의 근로소득을 누적하여 비교하면 대출 경험자가 졸업 후 18개월까지 지속해서 높은 누적소득을 얻고 있었다. 이는 대출 경험자가 낮은 임금의 일자리라도 조기에 수락하기 때문에 미취업 상태로 지내는 기간은 짧고, 첫 취업 이후에는 더 높은 빈도로 이직과 재취업을 통해 임금을 높여가기 때문이다. 대출 경험자는 대출 경험이 없는 이들과 비교하여 이직 및 재취업 시 임금 상승분이 2.6만원 높았으며, 직장을 옮기는 횟수 또한 유의하게 많았다. 이상의 결과를 종합하면, 노동시장 진입 직후에 조사된 임금을 사용하여 수행된 이전의 연구 결과는 학자금 대출이 임금에 미치는 부정적 영향을 과대 추정할 수 있음을 의미한다. 하지만 고용의 질을 살펴보면 대출 경험자의 대기업 정규직 취업률은 지속적으로 낮았다. 초기 고용의 질이 장기적으로 임금 상승 및 일자리 안정성의 차이에 따른 생애소득의 격차로 이어질 수 있음을 고려하면 이는 향후 장기적인 관점에서 대출 경험자의 노동시장 성과를 검토할 필요가 있음을 시사한다.

Purpose: Although appointed as a national competency standards (NCS) based reserves department, the department of emergency medical technology, an NCS-based emergency department, is mainly focused on subject deduction for a NCS-based curriculum. Methods: Job models were formed and verified by combining the competency unit of NCS and the duty of Developing a curriculum (DACUM) based on the development procedure indicated in the guidelines for a NCS-based curriculum. The mapping method of the subject was performed by deducting necessary competency units (duty) and competency unit elements (task) by connecting with the composition items of NCS and DACUM. Results: Job models combined with job analysis for the NCS and DACUM were reduced to 13 competency units (duty) and 79 competency unit elements (task). A modified method such as the 1:N method was mainly applied as a subject-matching method with consideration of the competency level and size of the competency unit. Conclusion: It would be a desirable direction to develop a NCS-based curriculum in the center of the practice subject in consideration of the size of the competency unit and competency level of the competency unit element. The existing curriculum should be promoted as a field-oriented curriculum at the complementary level.

Background: A job-exposure matrix (JEM) is an important surrogate indicator to evaluate past exposure levels. Although a Korean asbestos JEM has been constructed previously, this JEM includes only a few industrial and occupational groups. This study aimed to reconstruct the JEM by integrating the latest organized data to improve its utility. Methods: We used recent Korean standard industry and occupation codes and extracted 36 articles from a systematic literature review to initiate the reconstruction of the previous Korean asbestos JEM. The resulting data consisted of 141 combinations of industrial and occupational groups. Data from the Netherlands's JEM were also reviewed and categorized into 70 industrial and 117 occupational groups by matching with the Korean data. We also utilized Germany's data, which consisted of 10 industrial and 14 occupational groups. Results: The reconstructed Korean asbestos JEM had 141 combinations of industries and occupations. The time periods are from the 1980s to the 2000s in 10-year intervals. Most of the data were distributed between the 1990s and the 2000s. Occupations with high exposure to asbestos included knitting and weaving machine operators, automobile mechanics or assemblers, ship mechanics or assemblers, mineral ore and stone products processing mechanics, and metal casting machine operators or mold makers. Conclusions: The reconstructed Korean asbestos JEM has expanded the type and duration of the occupational groups of the previous JEM and can serve as an important reference tool for evaluating asbestos exposure and designing compensation and prevention policies in Korea.

In general, the line balancing problem is defined as of finding an assignment of the given jobs to the workstations under the precedence constraints given to the set of jobs. Usually, the objective is either minimizing the cycle time under the given number of workstations or minimizing the number of workstations under the given cycle time. In this paper, we present a new type of an assembly line balancing problem which occurs in an electronics company manufacturing home appliances. The main difference of the problem compared to the general line balancing problem lies in the structure of the precedence given to the set of jobs. In the problem, the set of jobs is partitioned into two disjoint subjects. One is called the set of fixed jobs and the other, the set of floating jobs. The fixed jobs should be processed in the linear order and some pair of the jobs should not be assigned to the same workstations. Whereas, to each floating job, a set of ranges is given. The range is given in terms of two fixed jobs and it means that the floating job can be processed after the first job is processed and before the second job is processed. There can be more than one range associated to a floating job. We present a procedure to find an approximate solution to the problem. The procedure consists of two major parts. One is to find the assignment of the floating jobs under the given (feasible) assignment of the fixed jobs. The problem can be viewed as a constrained bin packing problem. The other is to find the assignment of the whole jobs under the given linear precedence on the set of the floating jobs. First problem is NP-hard and we devise a heuristic procedure to the problem based on the transportation problem and matching problem. The second problem can be solved in polynomial time by the shortest path method. The algorithm works in iterative manner. One step is composed of two phases. In the first phase, we solve the constrained bin packing problem. In the second phase, the shortest path problem is solved using the phase 1 result. The result of the phase 2 is used as an input to the phase 1 problem at the next step. We test the proposed algorithm on the set of real data found in the washing machine assembly line.

Purpose - The purpose of this study was to substantiate the relationship between on-the-job training (OJT) characteristic factors and OJT outcomes and the moderating effect of the tie strength between a trainer and a trainee on the relationship. OJT characteristic factors were composed of a unit of work to be learned, trainee's motivation, trainer's ability, OJT design, and OJT support. OJT outcomes included job satisfaction and organizational commitment in the research. The tie strength means a sense of intimacy with a trainer. All of the OJT characteristic factors, OJT outcomes, and the tie strength were defined operationally as the perceived ones by a trainee. Research design, data, and methodology - This study analyzed the data of 302 employees in a domestic travel agency as early career for seven years or less. The main methods for the analysis were multiple linear regression analysis and moderating effect analysis. The whole process of the data analysis was conducted using the SPSS 21.0 for windows. Results - The results of the study are as follows: First, every five element of OJT, including unit of work to be learned, trainee's motivation, trainer's ability, OJT design, and OJT support, showed positive influence on OJT outcomes - job satisfaction and organizational commitment. Second, the tie strength between a trainer and a trainee was positively related with OJT outcomes. Finally, the strength of ties between the trainer and the trainee was found positively to moderate the relationship of a unit of work to be learned, OJT design, or OJT support, with OJT outcomes. However, the moderating effect of the tie strength was not significant statistically between the trainee's motivation or the trainer's ability, and OJT outcomes. Conclusion - In the study, it was demonstrated that every OJT characteristic factors have a positive contribution to job satisfaction and organizational commitment for early career employees. In addition, the study showed the need to pay attention to improve the quality of relationships between trainers and trainees, in order to increase the impact of a unit of work to be learned, OJT design, and OJT support. These findings suggest the implications in the three factors as external factors that constitute OJT. The three factors are made by HRD practitioners who are involved in design and operation of the program as well as their interventions to improve the quality of the relationship between trainers and trainees. On the other hand, it was demonstrated in the research that trainee's motivation and trainer's ability, regardless of their tie strength, have a direct impact on OJT outcomes by itself. Moreover, the trainee's motivation and trainer's ability are intrinsic characteristics, rather than external factors that constitute OJT. Therefore, they are unlikely to be changed by HRD practitioners' interventions. In conclusion, it was argued in the research that the trainee's motivation and trainer's ability should be a consideration in selecting and matching partners in OJT participants before starting OJT.

This research is concerned with production scheduling for FMS (Flexible Manufacturing System) which consists of machine centers served by cycle conveyor. The objective of the research is to develop and evaluate scheduling procedures to minimize the mean flow time. An optimal algorithm called SCTF (Shortest Circle Time First) is proposed when the conveyor runs at minimum possible speed (CS=1) and a heuristic algorithm called SCTJMF (Shortest Cycle Time and Job Matching Algorithm) is suggested when the conveyor runs at double speed (CS=2). The evaluation of the heuristic algorithm was implemented by comparison with the optimal algorithm for 112 experimentations for CS=1 and random schedule. The results showed that the proposed heuristic algorithm provides better solution that can be regarded noticeable when compared with SCTF algorithm and random scheduling.

Traditional intermediaries refer to service providers such as travel agents, real estate brokers, job agencies and insurance agents which matching services for buyers and suppliers in a traditional market. The introduction of Electronic commerce resulted in the automation of many tasks provided by intermediaries and seemed to eliminate the role of many traditional intermediaries, which is called disintermediation. However, depending on their market power, traditional intermediaries either will be disintermediated or fill new roles by providing added value and assistance, which is called reintermediation. According to the research of Alina M. Chircu et al. there are three conditions for reintermediation for traditional intermediaries. Three conditions are weak appropriability of EC innovations, ownership of co-specialized assets for both market intermediation and EC innovations and economies of scale. Besides these three reintermediation conditions, we hypothesize that leveraging BPO can be a suitable strategy for traditional intermediaries to be transformed into reintermediaries. Business Process Outsourcing (BPO) is the leveraging of technology or specialist process vendors to provide and manage an organization's critical and/or non-critical enterprise processes and applications. This paper will investigate the relationship between above reintermediation conditions including BPO and reintermediation.
