This article examines the reasons for the observed discrepancy between worker's actual and required levels of schooling and the resulting economic effects in wage and labor mobility using KRIVET's Graduates Economic Activities Survey in 2005. Overeducated workers in Korea are estimated to be 10.1%-20.7% among junior college graduates and 18.8% among university graduates for their first job according to job analysis method and worker's self-assessment method each. The effects of school quality-measured by the student/teacher ratio, school building area/student ratio-on the overeducation of their graduates are found to be mostly insignificant not only junior colleges but also universities. This founding implies that the increase of education investment from schools does not acquire any recognition from the labor market. Also, the effects of overeducation and school quality on wages are found to be insignificant and job mobility has little effects on improving overeducated workers' job match.

This study examines the job changes and the coincidence of job and major In the case of the youth, science and engineering graduates in Korea. The pattern of job changes and the coincidence of job and major get observed in the Unemployment Insurance Database and the Graduate List. This data enables us tracing all job changes in the labor market, and analysing the coincidence of job and major. The average rate of coincidence is not so high, the rate at first job is roughly one third. The youth with coincidence of job and major have earned less income than the youth without coincidence of job and major. But this result is impressive in the lower wage earners, any differences in regard to coincidence is not found in the upper wage earners. The probability of the coincidence of job and major is higher in case of the high wage and the high study attainments. The results suggests that the problem of the science and engineering graduates should be concentrated only on the lower manpower in the scientist and engineer jobs. Korean government have to lessen the number of entry into the science and engineering college and enlarge the number of entry into the science and engineering graduate school. Korean government have to prepare the system that aids establishment where the employee with coincidence of job and major earns more income.

This study was conducted by relative time study to identify the allowance time and basic work time, which is together composed of the total work time, in the wage composition and work process composition. This study was done for the case of a basic one person a group from thinning treatment for some conifer species such as Japanese red pine, Japanese larch, pitch pine and Korean pine. 1. In order to apply the Japanese allowance time of four species to the general conifer case, the maximum value of allowance time composition value among those of four species was selected. The results are as follows: delay time for person 1.8%, rest time 14.1%, delay time for machine 12.5% and wating time 0.4%. The some of ratios of adjustment allowance time is 28.8%. 2. Estimated wage basis time table, which can be used for wage table or process table, was prepared by adding up adjusted general allowance time and standard work time estimated by estimation equation for each species through the time study.

After analyzing and finding the explaining factors about the "Effect of My Mom's Friend's Son (MMFS Effect)" with online-surveyed data, we introduce this concept into the conventional job search theory to develop it further. We try to estimate its effects on the hazard rate of youth pre-employment duration with some proxy variables such as his/her parents' schooling, living with parents dummy, increasing rate of consumer price index representing the burdens of parents, monthly temporary/daily workers ratio, relative ratio of quarterly 90th percentile urban household income, monthly average wage differentials between the workers of large and small firms, etc. The results confirm us the fact that so called "MMFS Effect" has been effective enough and strengthened up to recently. The conventional job search theory should be extended to be able to introduce the influencing effects of other person's success, for instance MMFS's success, on the job search behavior of youths, too.

This paper presents examples of trolley wire resistance influential on the movement of tensioning devices. Therefore, this study is on the examples of trolley wire resistance which keep tensioning devices from working properly to the expansion and contraction in accordance with temperature change of overhead trolley wire system such as messenger wire and contact wire. Trolley wire resistance interrupts the working of tensioning device and drops the capacity of trolley wire. Reduced trolley wire capacity lowers the performance of current collection and has a bad effect on electrical train operation. So it is desirable to reduce the factors increasing trolley wire resistance to the minimum from the designing and construction stage of overhead trolley wire system. This study will introduce this problem and suggest the solution.

본논문(本論文)에서는 우리나라의 노동시장(勞動市場)의 구조(構造)를 동학적(動學的)으로 살펴보고 이에 따른 정책과제(政策課題)를 도출(導出)하기 위해 취업(就業)과 실업상태(失業狀態)를 번갈아 움직이는 노동자(勞動者) 행태(行態)의 결정요인(決定要因)을 실증분석(實證分析)하였다. 분석방법(分析方法)으로는 직업탐색이론(職業探索理論)을 이용(利用)하여 이론적(理論的)인 가설(假說)을 도출(導出)하였고, 계량적(計量的) 검증(檢證)을 위해 회귀모형(回歸模型)을 정형화(定型化)하였다. 통계자료(統計資料)는 1985년(年) 한해 동안의 "경제활동인구조사(經濟活動人口調査)"의 매월(每月) "테이프"에서 같은 근로자(勤勞者)를 11개월(個月) 동안 추적하여 분석(分析)을 위한 표본(標本)으로 이용(利用)하였다. 임금(賃金)은 취업(就業)에서 실업(失業)으로 변화(變化)할 확률(確率)에 대해 부(負)의 효과(效果)를 보이고 실업(失業)에서 벗어나 재취업(再就業)할 확률(確率)에도 부(負)의 효과(效果)를 나타내어 이론(理論)에서 도출(導出)된 가설(假設)이 검증(檢證)되었다. 연령(年齡)이 상태간(狀態間) 이동(移動)에 미친 효과(效果)는 부(負)의 값을 보였다. 그러나 이 효과(效果)는 일정한 연령(年齡)이 지나면 정(正)의 효과(效果)로 바뀌는 비선형성(非線型性)을 보였다. 이러한 결과(結果)에 입각(立脚)하여 우리는 높은 임금(賃金)을 받는 근로자(勤勞者)일수록 이직(移職)의 가능성(可能性)이 낮고 또한 실업상태(失業狀態)에서 재취직(再就職)의 가능성(可能性)이 낮다는 사실(事實) 등을 알 수 있다. 이에 따른 정책적(政策的) 시사점(示唆點)의 하나는 직업훈련(職業訓鍊)을 단순히 양적(量的)으로 확대(擴大)하기보다는 연령체계(年齡體系)에 맞추어 그 내용을 질적(質的)으로 조정(調整)하는 것이 바람직하다는 것이다.

This paper presents an empirical analysis on the relationship between consumer sentiment and macro-economic indices by consumer's characteristics such as age, income and employment type. According to the empirical analysis based on the Consumer Sentiment Index(CSI) of the Bank of Korea and other macro-economic indices, the following study findings are presented. First, individual consumer sentiment depends not only on GDP growth, but also on other macro-economic conditions such as wage, employment, consumer and asset price, and debt burden. Second, the degree of importance of the macro-economic indices on determining individual consumer sentiment varies strongly according to consumers' characteristics. These findings reveal that the gap between consumer sentiment and GDP growth can largely be explained by considering the other macro-economic indices and consumer's characteristics.

There has been a dramatic increase in the proportion of temporary employees in LIS fields, due to current trends of restructuring, automation, complete personnel systems, and complete wage systems. This research, therefore, conducted a survey exploring the current status and working environment of the temporary posts in LIS fields, in order to understand and direct the employment prospects of potential librarians. Results show that the average working period of more than half of temporary librarians are between 1-3 years. The total working period as a temporary librarian, including former experiences in their career, were evenly distributed between 1-5 years. Among those, being temporary often persisted, as 32% of temporary librarians stayed in their temporary status for more than 5 years. Second, temporary librarians perceived themselves as working the same hours as regular librarians, having independent or assistant tasks to regular librarians, and having a neutral or larger amount of tasks than regular librarians. Third, temporary librarians are employed and contracted from the work place, generally having contracts of less than 2 years or an open contract, which shows a serious level of job instability. Therefore, we should consider the following: proper remuneration for work of equal value, professional contractors, the supplementation of the total wage system and the number of public employees in the system as well as changing temporary positions to permanent positions and so on.

This study was conducted to compare job satisfaction and factors related to job satisfaction between permanently and temporarily employed dietitians in school foodservices in the Gyeongsangnam-do area. A total of 204 questionnaires were used in the final analysis. The average age, length of employment, and monthly wage of temporarily employed dietitians was significantly lower than those of permanently employed dietitians. However, there was no significant difference of overall job satisfaction between permanently and temporarily employed dietitians, although the average pay, welfare benefits, and promotion factors for permanently employed dietitians was significantly higher. Work and pay factors had significant effects on the overall job satisfaction of permanently employed dietitians, while work factors and work atmosphere had significant effects on the overall job satisfaction of temporarily employed dietitians. In conclusion, there was a significant difference in overall factors related to job satisfaction between permanently employed dietitian and temporarily employed dietitians. The pay, welfare benefits, and promotion condition of temporarily employed dietitians should be improved to ensure the efficient management of the school foodservice workforce in the future.
