The purpose of this research was to analyze the job satisfaction and business attitudes of restaurant owners in order to explore solutions for improving restaurant management. The results were as follows : 1) The motive for starting a restaurant business was vocational aptitude \longrightarrow possibilities \longrightarrow good income : 2) In terms of job satisfaction, most respondents were satisfied with both the work itself and the income. It was also observed that the younger owners were more satisfied with their jobs than the older owners : 3) Increased costs, including labor and food costs, was indicated as the biggest problem in restaurant management. Respondents also perceived labor shortage as one of the most difficult problems. Men were more likely than women to consider the following problems as being more serious: rent, financial problems, taxes, regulation restrictions, menu development and customer complaints. It was found that as the size of the restaurants grew, the respondents perceived the shortage of labor as the hardest part of running a business : 4) Respondents agreed that employing good foodservice workers was the most important part of foodservice management. Owners also believed that they needed more research time for menu and service development 5) To be successful, the restaurant owners paid the most careful attention to food taste. Service, sanitation, and menu development were also emphasized. Respondents stressed the focus on service, good relationships, diligence, and faithfulness in order to be a good restaurant owner. The results of this research suggest that restaurant owners should have more professional conscientiousness to succeed in their own businesses, as well as improve the quality of the foodservice industry. Other important aspects related to the overall improved quality of the foodservice industry are: the continuation of government support, the enlargement of educational opportunities and greater respect for foodservice employees.

대졸 청년층의 노동이동을 대학졸업생자료와 고용보험DB를 결합한 자료로 분석하였다. 우리나라 대졸 청년들의 졸업 후 4년 동안 평균 취업회수는 1.68회였고, 직장경험이 늘어남에 따라 직장근속이 늘고 있으며, 취업회수가 많을수록 총근속기간이 더 길었다. 대졸 청년층들의 노동이동에서 업종과 직종이 일치하지 않는 경우가 많았다. 대졸 청년층들이 비수도권에서 수도권으로 이동하는 비율은 수도권에서 비수도권으로 이동하는 비율보다 높아 인적자원의 수도권 집중이 되고 있음을 보이나 이는 수요측 요인으로 파악된다. 대졸 청년층은 노동이동을 통하여 상위의 직종을 얻고 있으나, 작은 규모의 기업으로 이동하고 있다. 직장경험이 많은 대졸 청년들의 첫 직장 임금은 낮은 것으로 나타났으나, 이들은 직장 이동을 통해 임금수준을 증가시키고 있었다. 인문사회계 출신보다는 이공계 출신이 직장이동을 할 확률이 높았으며, 임금이 높을수록 직장이동을 할 확률은 떨어지고 있다. 수능점수가 높은 경우 직장이동을 할 확률이 낮았다. 직장이동을 통해서 대학에서의 전공과 일치하지 않는 직무로 나갈 가능성이 큰 것으로 나타났기 때문에 청년층의 노동이동을 경력형성의 방향으로 유도할 수 있도록 하는 정책대안이 필요하다. 또한 대학 졸업자의 노동의 질이 보다 높아질 수 있도록 대학교육의 강화 및 대학생 수의 감축을 위한 정책대안이 모색될 필요가 있다.

Nowdays the prison is the only correctional for juvenile delinquents not to be the second offenders in Korea. Originally the correctional education aims to let criminals go back to the society as a decent citizen after correcting them and prevent them from comminitting crimes repeatedly. Being considered to increase the second offenders in juvenile delinquency, the purpose of this study is to investigate the actual condition and problems of juvenile correctional education in Korea and to find out the solution of problems. First of all, this study examines the actual condition of the juvenile delinquency in Korea. The number of juvenile crimes has been increased from 1985 to 1995. In 1997, the current education in correctinal institutions for juvenile delinquents is inferior to that of developed countries. On the basis of this investigation, improvement plans which will be fit for the circumstances in Korea are suggested. The conclusion of this study are summarized as follows 1. Correctional institutions will be improved to accommodate the proper number of convicts. 2. Correctional officers should be qualified proffessinals who can achieve the aim of correctional education successfully. 3. In order to cultivate he social adaptability of convicts, the expansion of open prison is needed. 4. It is neccessary to classify convicts by means of moderized and scientific methods. 5. Correctinal education consist of various practical courses on jobs, After complenting these vocatinal training, the convict can obtain certificates. 6. The government has to has to plan policies that the released convicts can get jobs for living. 7. Owing to keeping prisons sanitary, it is very helpful for convicts to have thebelief that they are not abandoned by the member of their society. 8. Convicts are given opportunities to participate religious activities by their free-will. If above improvement plans are sufficiently accomplished, correctinal education will obtain good results, It is also effective to minimize the repetition of offence by ex-convicts.

본 논문은 파트타임근로를 통해서 짧은 시간 내에 높은 고용률 향상이라는 성과를 달성한 네델란드에서의 파트타임근로의 현황과 전망, 제도와 정책 등을 종합적으로 살펴보는 글이다. 네델란드는 파트타임근로를 통한 고용률 제고뿐만 아니라 양질의 파트타임을 만들어냈다는 점에서 주목받고 있다. 네델란드에서 파트타임근로가 증가한 것은 시장, 제도, 정책, 그리고 노사관계 등 다양한 요인들이 파트타임근로를 촉진하는 방향으로 서로 보완하면서 발전하였기 때문이다. 노동시장에서는 여성의 경제활동참가 증가와 기업의 파트타임수요의 증가라는 선순환 구조가 형성되었고, 파트타임근로를 보호하고 파트타임에 유리하도록 인센티브 구조를 재설계하며 근로시간선택권을 보장하며 보육시스템을 강화하는 제도나 정책이 지속적으로 강화되었다. 그러나 이러한 시장에서의 수요-공급의 선순환 구조와 파트타임을 촉진한 제도와 정책도 노사정 사이의 사회적 합의라는 커다란 틀 속에서 그에 기초해서 이루어진 것이었다는 점이 중요하다. 또한 거의 30년 가까지 지속된 네델란드모델은 노동시장의 문화와 관행으로 정착되어 풀타임근로나 노동시간 확대의 방향으로 전환하기는 어려운 것으로 평가된다. 따라서 네델란드 모델은 네델란드의 사회적 조건 하에서 성립한 특수한 모델이고 높은 수준의 사회적 합의를 기초로 하여 제도와 시장이 보완적으로 잘 결합되어 있는 모델이기 때문에 여타 국가가 부분적인 제도 이식을 통해서 성과를 내기는 어렵다고 판단된다.

In this study, two representative measures in the job-focused approach and the employee-focused approach of emotional labor are explored to examine dimensionality and the predictability of each emotional labor measure on key consequences that include job stress, customer orientation, and job satisfaction. Data obtained from 193 department store apparel saleswomen were submitted for analysis. The results show that the emotional dissonance and emotional effort of the Kruml and Geddes measure are good predictors for job stress, customer orientation, and job satisfaction. In a test of the Davies measure, job stress is predicted by emotional dissonance and frequency while customer orientation is predicted by duration, variety, and the frequency of emotional expression in jobs. Duration is also a key predictor for job satisfaction. The result confirm the dimensionality and predictability of two emotional labor measures as well as suggests the need for the careful selection and refinement of appropriate measures according to consequences.

Job shop scheduling with m different machines and n different jobs is a NP-hard problem of combinatorial optimization. The purpose of the paper is to develop the heuristic method using tabu search for job shop scheduling to minimize makespan or mean flowtime. To apply tabu search to job shop scheduling problem, in this paper we propose the several move methods that employ insert moves in order to generate the neighbor solutions, and present the efficient rescheduling procedure that yields active schedule for a changed operation sequence by a move of operations. We also discuss the tabu search techniques of diversifying the search of solution space as well as the simple tabu search. By experiments, we find the appropriate tabu list size and tabu attributes, and analyze the proposed tabu search techniques with respect to the quality of solutions and the efforts of computation. The experimental results show that the proposed tabu search techniques using long-term memory function have the ability to search a good solution, and are more efficient in the mean flowtime minimization problem than in the makespan minimization.
