본 논문은 한국노동패널(KLIPS) 자료를 활용하여 국내 노동시장에서의 인적 네트워크 활용의 효과성을 검증하고 임금근로자 개인의 구직 네트워크 가치를 추정하였다. 흔히 인적 네트워크를 활용한 이직을 '연줄' 혹은 '정실인사'라고 하여 부정적으로 보는 견해가 많으나, 본 연구는 인적 네트워크가 이직자와 구인자 사이의 정보전달기능을 수행함으로써 사회 전반의 일자리 매치(job match)의 적합성을 증대시키는 긍정적 기능을 수행하고 있음을 입증하고 있다. Propensity Score Matching 방법론을 활용하여 검증한 결과, 자발적 이직자들의 이직을 네트워크형 이직과 비네트워크형 이직으로 구분하여 보았을 때, 네트워크형 이직만이 교육수준 및 기술수준의 적합도를 각기 (100점 만점에서) 2.13점과 2.52점 개선시키는 것으로 확인되었으며, 이러한 적합도의 개선은 월 4.074만원(2010년 기준)의 임금상승효과로도 재확인되었다. 덧붙여, 이를 활용하여 임금근로자 개인의 구직 네트워크의 가치를 추정해 보면, 구직 네트워크의 생애 금전적 가치는 1,872.0만원으로 집계되었으며, 여기에 주관적 만족도에 대한 보상측면까지 고려하면, 만족도 1점의 현금가치를 n만원으로 환산할 때, 대략 (1,872.0+758.2n)만원에 이르는 것으로 집계되었다.

Economic transformations have led to an increase in the role of creative assets and their central role in public life. Changes in creative activity have led to a change in the organization of the work of institutes engaged in the training of specialists, in particular teachers of labor education. Methods and approaches to training determine the development of creative industries, being the basis for models of professional training of future teachers of labor training. The purpose of an article was to develop a modern model of professional training of future teachers of labor training based on the concept of creative economy. The methodology is based on the concepts of holistic craft and creative economy. Based on the integration of pedagogical learning models "Craft as design and problem-solving", "Craft as skill and knowledge building", "Craft as product-making" and "Craft as self-expression" developed and experimentally confirmed the conceptual model of professional training of future teachers of labor training. The proposed model forms a practitioner with professional, technical, digital and creative skills who is able to transfer the experience to students. The training course "Creativity and creative thinking" has been developed. The model provided for the development of a course based on the strategy of developing professional creativity, flexibility, improvisation, openness, student activity, joint practice, student-oriented approach. The practical value implies the adaptation of the developed model of professional training of future teachers of labor education during the training of teachers in higher education, which is confirmed in the experiment.

본 연구는 2009년부터 2012년까지의 복지패널자료로 노동시간과 임금의 변화를 잠재적인 추이를 통해 살펴보고, 이들의 관계 패턴을 통해 역동적인 노동시장 안에서 연도별 개인의 효용극대화점의 변화와 노동공급곡선의 방향을 살펴보아 앞으로의 방향성을 예측해 보고자 한다. 연구대상과 자료는 한국복지패널의 2009년부터 2012년간 가구 월기준으로 노동시간과 임금을 측정 및 분석하였다. 연구결과로 먼저, 2009년에서 2012년으로 변화함에 따라 노동시간과 임금은 증가함을 예측할 수 있었으며, 비선형 성장곡선이 아닌 선형으로 나타났다. 둘째, 2009년에서 2012년 동안 추정해 보면 노동시간의 SLOPE와 임금의 SLOPE간에 높은 상관관계를 보였다. 셋째, 2009년에서 2012년까지 노동시간과 임금이 함께 증가하는 것으로 나타났기 때문에 노동공급곡선 가구의 한계효용점은 우상향으로 이동한다. 노동공급곡선이 우상향하는 추이를 지속적으로 보이므로 대체효과가 소득효과를 좀 더 압도하고 있다고 볼 수 있다.

This study explores the overall attitudes of family life used data from dual-earner wives(N=773) who contribute to household economics. The major hypothesis of this study is that employed wives are more likely to be equal in performing their roles at home than full-time homemakers. However, a pattern of asymmetry exists concerning the role performance of wives regardless of their employment The specific findings are as follows : (1) Wives indicate the instrumental and the dual(mixed the traditional value with the developmental value) perceptions of marriage. (2) It is not equal in the distribution of family resources and the procedure of decision-making among couples. (3) The household labor is mainly performed by wives. (4) Wives are mainly responsible for child-rearing and indicate the inconsistent perception of mothering From the findings study suggests that : (1) Future research might investigate the reason of low family contribution among employed wives (2) The egalitarianism (role sharing) in household labor and child rearing might be extended. 93) women might be educated to pursue an independent life.

This study applied Data Envelopment Analysis to a set of Korean Public Corporation Medical Centers and Japanese Municipal Hospitals to compare their relative human resource efficiencies. Based on the data provided on the inputs and outputs, the analysis showed Japanese municipal hospitals were relatively efficient than Korean hospitals. The result of analysing BCC model shows 5 hospitals in Japan and 7 in Korea with an efficiency rating of less than 1 as considered relatively inefficient. For the inefficient hospitals the manner in which inefficient hospitals may be made efficient were indicated by the managerial strategies based on dual variables. A subsequent analysis of Wilcoxon rank-sum test revealed that the medical revenue per medical expense, labor cost per value added revenue were statistically significant between efficient and inefficient Korean hospitals and medical revenue per medical expense, labor cost per value added revenue, bed occupancy rate, average length of stay, rate of personnel expenses per medical revenue were statistically significant between efficient and inefficient Japanese hospitals.

This paper empirically investigates the role of R&D intensity on market concentration of firms using four key market valuation variables, namely (1) market share, (2) labor intensity, (3) firm age and, (4) firm's market value. The empirical tests use database at firm level for the Indian IT sector from 1999 to 2013 from the CMIE Prowess database. The results of the regression analyses partially support our hypothesis that R&D intensity positively influences firm's market value measure by the H-index. The test results are consistent with the hypotheses that R&D spending is more valuable for firms with larger market shares, higher labor intensity, and firms that are diversified.

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.

Although the Pontryagin's maximum principle theory is widely applied in control problems, its contribution to the solution procedure have been restricted just to figure out the rough picture of true solutions, probably due to the complexity of the two-point boundary value problems. This paper discusses a numerical approach to solve the control problems in connection with the two -point boundary value problems. A model of labor management negotiation during a strike has been constructed and solved explicitly by us of DVCPR subroutine introduced in IMSL. The results have been turned out that the management is better increase wage very slowly during the strike period, while , on the labor side, it is more effective to show the high intensity of demonstration against the company at the outset and gradually decrease it.

Most of fruit quality classification has been done by time consuming, inaccurate and intensive manual labor. This study proposed an automated fruit grading system based on appearances and internal flavors. In this study, image processing technique and a weight checker were used to measure the value of appearance features and the near infrared spectroscopy analysis method was used to estimate the value of internal flavors. Additionally, I suggested 8x8x5x5 ANN based fruit quality classifier model to grade fruits quality. The proposed automated fruit quality classification system is expected to be very beneficial for many farms where heavy manual labor is usually needed for fruit quality classification.
