Since the early 1990s, the Korean courts have tilted in the direction of giving greater freedom to employers by relaxing the restrictions on dismissal for economic reasons. During the Korean economic crisis of 1998, the Korean Labor Standard Act was also revised for the purpose of relieving the limitation of employer's discretion in employment adjustment. From the Coasian perspective, this article analyze how implied contracts for the employee's reliance and employer's compliance might be influenced after the formal law is revised. We demonstrate that, if the legal change results in excessive intervention, it might cause the employers to over-breach, the employees to under-rely, and the accompanying efficiency to decrease. We scrutinize the total population of unjust dismissal cases since 1987 in order to investigate how the legal changes in Korea have affected the implied contracts. Our empirical analysis raises a possibility that Korean legal changes made in 1990s might have increased the employer's opportunism and decreased the employer's reliance effort.

금속을 용해 응고시킬 때 생성되는 소위, 주조 결함이나 소결금속 내의 기공은 재료의 성능이나 강도를 현저하게 낮추는 결함으로서 예전부터 기피되어 왔다. 또한, 재료공정에 있어서도 여하의 기공이나 기포가 없는 치밀한 고강도 및 고기능성 재료를 개발하는 것에 최대한의 주의와 관심을 기울여 왔다. 반면에 자연계의 천연물이나 인공물을 둘러보면 그 대부분이 다공질임을 쉽게 눈치챌 수 있다. 예를 들어 목재, 지엽 등의 생물을 시작해서 콘크리트 등의 인공물, 우리 체내의 뼈도 전형적인 다공질구조로 구성되어 있다. 이러한 구조로부터 재료의 재질제어 이외에 구조제어라는 새로운 어프로치를 고려할 수 있고, 최근 들어, 금속재료에 있어서도 이러한 다공질 구조에 관한 연구가 활성화되어 충격흡수재, 생체재료, 베어링재료 등의 다양한 응용이 전개되고 있다. 원주상의 방향성 기공을 갖는 로터스 금속의 제조 원리는 용융금속의 높은 가스용해도와 고체금속의 낮은 가스고용도의 차이를 이용하여 응고할 때 고용되지 않는 가스원자가 기포를 형성시키는 것이다. 수소용해도는 모든 금속에 있어서 온도상승에 따라 증가하지만 융점에 있어서 용해도의 불연속적 증가를 나타내며 응고할 때 고액계면에서 다량의 가스를 방출하고 기공 생성을 야기한다. 특히, 고 액상에 있어서 수소용해도 차가 큰 마그네슘, 니켈, 철, 동 등은 기포를 생성하기 쉽다. 또한 기공의 배열구조를 제어하기 위해 일방향응고법를 이용하여 기공에 방향성을 부여한다. 외관상 기공구조가 연근뿌리를 닮은 것으로 부터 로터스 금속이라는 명칭이 널리 알려져 있다. 이와 같은 제조방법에 의해 로터스 금속은 기공 방향, 기공크기, 기공률을 자유롭게 제어할 수 있고 우수한 기계적 성질이 기존의 발포금속, 소결금속과 전혀 다른 특성을 가지고 있다. 이러한 기공구조는 용해온도, 응고속도, 분위기 가스압, 불활성가스와의 혼합체적비 등의 제어를 통해서 조절할 수 있다. 이와 같이 제조한 방향성 다공질금속은 BT (인플란트, 생체적합성, 저탄성, 경량), ST (초음속기엔진부품, 경량), IT (고성능수냉모듈), ET(고온촉매, 필터)의 분야로의 응용을 기대한다.

This study analyzes the impacts of mixed-use development and transportation on housing values in Seoul, Korea. An index measuring the land use mix is proposed using three components of land uses, residence, office, and retail, which are the essential elements for everyday urban life. This index offers a relatively easy way in measuring the level of mixed-use and proves itself useful providing sensible and reliable results in this empirical study. Also surface and underground transportation accessibilities are measured. By covering both surface and underground, a comprehensive view of Seoul's transportation accessibility is provided. Finally, housing value models are constructed with developed variables, i.e. land use mix index and accessibility measures, as well as relevant socio-economic variables. The empirical outcomes verifies that mixed-use development and transportation accessibility positively affect housing values.

The purposes of this study are to identify many implications of commuting regional type according to the features of foreigner commuting. Research on the pattern of distribution of foreigners has been very simple and limited because foreigners usually lived together in a specific area, and their workplace often tended to be their residence. However they currently live dispersed more Widely, and their job and housing increasingly tend to be mismatched. This study divided areas inhabited by foreigners into general one characterized by job-housing match and exceptional one characterized by job-housing mismatch, and then examined the features of foreigner commuting. General commute type showed a high rate of intra area commute and foreign workers' universal features. Inflow commute type showing high E/R ratio. In these areas, outflow commuters had a short journey to work while inflow commuters had relatively a long journey to work, and professionals accounted for a high proportion of employees. Outflow commute type showing low E/R ratio. In these areas, outflow commuters had a long journey to work while inflow commuters had a relatively short journey to work. The composition ratio of three commute types was different according to nationality and visa type.

This paper explores the empirical performances of the workout companies with special interests in the effectiveness of corporate reorganizing tools on their revitalization. In the empirical analysis it considers the criteria of success or failure in restructuring from both creditors' and debtors' perspectives. The key results are summarized as follows. First, the initial conditions on the debt structure of the workout companies are significantly related to the revitalization from both creditors' and debtors' point of view. Second, the debt restructuring instruments are insignificant in the success of corporate turnarounds while the debt-to-equity conversion has been a relatively effective tool. Third, the self-restructuring efforts, employment downsizing and governance reshuffling do not affect the performances significantly. The higher importance of initial conditions than corporate restructuring efforts may imply that Korean corporate workouts serve better to the needs of creditor financial institutions which are to maximize debt recovery and of the government which is to overcome financial crisis.

Infrastructure engineering is a field that supports construction (assembly) as a representative industry that creates high added value and jobs by combining science and technology with knowledge, though its importance is underestimated. According to a report from the Ministry of Land, Infrastructure and Transport (Korea), the value-added rate (65.3%) of the engineering industry and the employment inducement coefficient (14 employees per billion won) are three times higher than in manufacturing. In particular,the forward value chain (such as project management and basic design) accounts for less than 10~15% of the total project cost but determines the overall price and quality of the infrastructure facilities. In this study, a work break-down system, design support module and database development method for road design projects for design platform development is presented. Based on the presented development method, a cloud-based infrastructure design platform's prototype is developed. The developed infrastructure engineering platform is expected to provide a web-based design work environment without time/space restrictions and greatly contribute to winning overseas business orders and securing competitiveness.

The purpose of this study is to analyze the impact of reading on self-efficacy and multicultural acceptance. The Korean Education and Employment Pannel II data were used for the analysis. Through analyzing the data with latent growth model, the growth trajectories for reading, self-efficacy, and multicultural acceptance were identified, and the relationship between three variances were analyzed using multi-variate latent growth model. As results, reading books, self-efficacy, and multicultural acceptance were decreased, as times go by. Next, the intercept of reading was postively related with self-efficacy and multicultural acceptance. Finally, self-efficacy mediated between the intercept of reading and the multicultural acceptance, and it's statistically significant.

We empirically investigate the determinants of a firm's exit from exporting, using Korean manufacturing firm-level data for the period from 2006 to 2014. Specifically, we estimate the effects of not only firm-level and industry-level characteristics, but also macroeconomic variables on the probability that a firm stops exporting by applying a Complementary Log-Log Model analysis. The results of our estimation suggest that firm-level heterogeneity, such as workforce size, capital intensity, intangible assets and foreign ownership, industry-level variation, such as the labor displacement rate, and macroeconomic variables, such as domestic demand and world demand, significantly affect the possibility of a firm ceasing exports. Also, we show that market interest rates increase the possibility of an export cessation and that the effects of market interest rates are more pronounced on firms with a higher debt ratio. In the primary exporting industries, the probability of a firm ceasing exports decreases as productivity at the firm rises.

By analyzing 1998~2008 Korean Labor and Income Panel Study(KLIPS), this study examines socio-economic characteristics of people who become poor. The study also explores the reason why they are in the state of poverty. To find determinants affecting poverty entrance, discrete-time hazard models are applied. Major findings are as follows. The socio-economic characteristics driving people into poverty are in the middle way of the long-term poor and the non-poor, combining the characteristics of both groups. This implies that many cases of the newly poor tend to enter and exit from poverty repeatedly. Poverty entry rate was at a high level right after the economic crises, then was a downturn and remained fairly stable since 2000. However, the young, the high-educated, and even the professional are on the rise as a new poverty group. The major reason people become poor is temporary job loss. This factor is confirmed again by multi-variate analyses. In building anti-poverty policies, it is important to distinguish the long-term poor from the short-term poor. For the long-term poor, virtually the only affective policy will be income support. On the other hand, a labor-market strategy for jos security will be more effective for the short-term poor. The characteristics and determinants of poverty entry may affect poverty duration and exit in the future. Future research will be needed to investigate the relationship among these factors.
