  • 본고는 생산현장에서의 인적자본 축적, 즉 근로자의 숙련형성에 영향을 주는 요인들을 실증적으로 찾아보고, 형성된 숙련이 생산성 향상에 기여하고 있는 것을 확인한다. 먼저 숙련형성의 유형은 '단순/견습근로자 < 단능근로자 < 다능근로자'의 직렬적 순서이다. 제품수요의 급변성과 비정상적인 상황 발생이라는 외부적 내부적 불확실성이 클수록 다능화가 활발하게 이루어지고 있으며, 선배 동료 근로자와의 상호학습, 근로자의 의사결정 참여, 직무 순환 등의 인적자원관리 관행들도 다능화를 촉진한다. 이러한 발견들로부터 생산 현장에서의 숙련형성은 다능화로 대표될 수 있다고 판단된다. 기업의 노동생산성 성장률을 기업의 성장률이라고 하면, 불확실성과 인적자원관리 관행들은 다능화를 통해서 기업의 성장에 영향을 준다. 구체적으로 기업의 다능화 비율이 0.1만큼 올라감에 따라 노동생산성 성장률이 0.019만큼 증가한다. 이것은 또한 다능화가 인적자원관리 관행들에 영향을 받아 형성되는 인적자본 축적의 한 결과라는 주장에 대한 근거가 될 수 있다.

  • This study investigates empirically the export competitiveness of Korea and Japan in America by calculating 4 indexes such as market share index(MSI), export similarity index(ESI), market comparative adventage index(MCAI) and market share expansion ratio(MSER)-export similarity deepening ratio(ESDR). The empirical finding of this analysis shows that Korea is competitive in the labor-intensive products and Japan in the technology-intensive products. This result also meets the general understandings that Japan is superior to Korea in the export competitiveness such as value added of goods, etc. Therefore, in order to strengthen the export competitiveness of Korea in the US market, it's desirable for our firms and government to improve the quality of product ranges by developing technologies focused on the higher value-added products.

  • This study was to find out the status of labor division between rural husband and wife by measuring the labor time for tasks, the ratio of relative contribution toward work, and work segregation. Data used in this study were collected fro 424 persons of 212 farm households mainly cultivating rice and barley. The results of this study were as follows : 1) In the case of work directly related to farming, working hours of husband were significantly longer than those of wife during the farming and off-farming season. In contrast working hours of wife for housekeeping were significantly longer than those of husband during both seasons. 2) The ratio of relative contribution toward farming work of husband was a little higher than that of wife during farming and off-farming season. But this toward housekeeping work was less than that of wife. 3) The degree of gender segregation in farming was 0.33 during the farming season and 0.01 during the off-farming season. The kinds of work and time distribution were relatively same. The degree of gender segregation in housekeeping was 0.79 during the farming season and 0.72 during the off-farming season. These values showed inequality of work segregation in the kind of work and time distribution.

  • The productivity of a hospital foodservice system has a significant implication in hospital management as costs for labor and material increase, competitions among hospitals increase, and patients' expectations as to the quality of hospital services increase. The foodservice is characterized by its labor intensiveness. The objective of this study was to examine associations between operational and managerial factors and the productivity of dishwashing work in hospital foodservice systems. The labor productivity in 20 conventional food service systems was assessed and related to a number of influencing variables within the system. The productivity measurement was based upon the total dish equivalents as a ratio of the total direct and non-direct labor hours required to wash these dishes. 20 hospitals with more than 500 beds located in Seoul were surveyed to obtain data for study variables. Questionnaire and a survey form were mailed. Statistical methods used in this study were descriptive analysis and Pearson product moment correlation analysis. Hospital system characteristic which was found to correlate significantly with productivity was the ratio of dish loss. As this increased, the productivity level increased.

  • Worldwide consumption of vegetable soybean has been increasing recently, but, in the process of vegetable soybean production threshing and seperation work accounts for about $80\%$ of overall labor. Therefore, developing of the vegetable soybean thresher is necessary to reduce the cost of labor. The main objective of this study is to develop the vegetable soybean thresher which is suitable for domestic circumstances. The threshing and separating performance, operating cost, and field capacity of developed vegetable soybean thresher are investigated and analysed. The results are as follows. The effective field capacity of the developed vegetable soybean thresher was shown as 4.8hr/10a, and reduced as much as 11.7 times compared with human labor. The ratio of unthreshed soybean-pod to stem after threshing work was shown as $1.5\%$ and the damaged pod ratio of detached soybean was shown as $1.8\%$. The cost of human labor was shown as 2,560,000 won/ha, but the operating of the developed vegetable soybean thresher was shown as 503,000won/ha. If the vegetable soybean thresher would be used in our farm, the minimum cultivation area appeard to be 22.7a for the cost effective management.

  • Subjects : A literature research on the constitution and medicinal effect & adaptation diseases of "Bullsusan". "Bullsusan" is a herbal prescription composed of Angelicae Gigantis Radix(當歸) and Cnidii Rhizoma(川芎). Objectives : Through the researching on the records of "Bullsusan" in Korean Traditional Medical Books, gain the literature evidence for adaptation to these days child labor as a pre-labor keeping herbal medicine. And have detailed consideration on the constitution of prescription and medicinal effect & adaptation diseases of "Bullsusan". Methods : First, researched the records of "Bullsusan" in Korean Traditional Medical Books which were included at A Series of Korean Medicine(韓國醫學大系) and analysed component ratio, nickname, herbal manufacture and drug processing method, medicinal effect and adaptation diseases. Second, referred related Korean and Chinese researches that examined the medicinal effect and adaptation diseases of "Bullsusan" by scientific experimentation. Conclusions : We found total 46 records of "Bullsusan" from 20 kinds of Korean Traditional Medical Books included at A Series of Korean Medicine. Prescription component ratio of Angelicae Gigantis Radix and Cnidii Rhizoma were 3:2, 1:1, 2:1, 1:1. 3:2 had most 20 records and 1:1 had second 14 records. Especially 1:1 had a tendency of having nickname "Goonguitang", but not must had. First herbal manufacture was powder, it had 8 records. First drug processing method was decocting with water and alcohol, had 19 records. Medical Effects of "Bullsusan" can be induced to next 8, that were "remove get bad blood, give birth new blood", "easy labor by reducing fetal volume", "acceleration of labor", "test of fetal survival, elimination of dead embryo", "elimination of placenta", "revive", "allaying pain", "nourish the blood". From these medical effects, 9 adaptation diseases can be induced. That were "threatened abortion", "womb ache and vaginal bleeding by spontaneous abortion", "pre-labor keeping(prevention of hard labor)", "acceleration of labor", "hard labor", "missed abortion", "postnatal vaginal bleeding, dizziness, asthma, headache, womb ache", "postnatal mastoptosis and mastodynia", "first aid symptom like as dizziness, unconsciousness, stroke caused by excessive bleeding". The medical effect of "acceleration of labor" and "elimination of placenta" have been examined by modern clinical research. The effect of "remove get bad blood, give birth new blood", "allaying pain" and "nourish the blood" have been examined by modern experimental study. But overdosing on "Bullsusan" to pregnant mouse can cause natural abortion, so the proper dose of "Bullsusan" in pregnant period is very important.
