  • Additional costs as well as schedule delay are occurred due to change orders in today's construction projects. Additional costs, overhead calculation methods are of various types. In a foreign country cases, many claims related to the loss of labor productivity quote research statistics data. In domestic cases, the study of the reason why the loss of labor productivity occurs and its effect have not been performed. Therefore, this paper analyzes factors affecting lost productivity and a methodology is presented to estimate the lost productivity.

  • Object : From the ancient times, the importance of childbirth has been well recognized by Korean Traditional Medicine. Numeral methods have been developed to ease the labor process and keep the mother and child healthy from conception to labor. Bulsusan(佛手散) is one of the main remedies to healthy labor in KTM, both widely known and applied as well. Method : This paper examines the labor theory and practice of KTM focused on Bulsusan which is composed of Angelica gigas Nakai(當歸) and Cnidium officinale MAKINO(川芎). Result : 1. From the ancient times until the Q$\bar{i}$ng period, much attention was placed to the handling of the placenta, as it was conceived as bearing much relation to the health of the mother and her fate, and thus included in the labor process. 2. There was a recognition of the 'birth pulse[離經脈]', an intense change in the pulse that presents itself prior to somatic signs of labor. 3. There were numerous prescriptions that were administered beforehand to ease the process. They are mostly constituted with medicinals that nurture Gi(氣) and stimulate its flow, which in turn makes the fetus firm and reduces the volume, easing the labor process. 4. The medical practice of labor-induction was called 'Choesaeng(催生)'. The prescriptions which functioned as such were mostly constituted with blood medicinals such as Angelica gigas Nakai and Cnidium officinale MAKINO, those which nurture both Gi(氣) and blood, and medicinals that physically lubricate the labor pathway such as honey, oil and Talcum(滑石). Conclusion : Bulsusan can be used in most problems concerning pregnancy and labor, and cases of emergency blood loss due to injury. The term 'bulsu(佛手)' infers to the medical ability of the great doctor who takes care of major blood-loss situations resulting from discharge of dead fetus, cesarean delivery, etc. The prescription name takes after this meaning, as it deals with similar conditions in its effect.

  • This paper investigates the success factors of labor mediation using the Survey on the Problems and Improvements of Mediation Service by the Labor Relation Commission which was conducted by the Ministry of Labor in 2000. When the parties of labor and management which took mediation service belong to the manufacturing industry and the Minju-nochong, they are found to have less chance to change their negotiation attitude favorably toward agreement in mediation process and to adopt an agreement proposal made by the mediator. Those who took mediation service more frequently in the past tend to have lower chance to make use of mediation service successfully. Those who saw the mediators of their dispute to be qualified with fairness and expertise tend to have higher chance. As the time of mediation meeting lengthens, it is more likely for them to reach an agreement with assistance by the mediators.

  • Nowadays much efforts for evaluating the productivity of port physical distribution system to meet the rapid change of the port and shipping circumstances has been made continuously all over the world. The major part of these efforts is the improvement of the productivity of cargo handling system. The cargo equipment system as infrastructure in the cargo handling system is organized well in some degrees, but the management system of manpower as upper structure is still remained in an insufficient degree. There is little study, so far, on a systematic research for the management of port labor gang, and even those were mainly depended on rule of thumb. The object of this study is to introduce the method of optimal allocation and assignment for the labor gang in single ship, which was suggested as a first stage in dealing with them generally. The problem of optimal allocation and assignment of the labor gang can be (I) formalized with multi-stage allocation and assignment of the labor gang can be. (II) dealt with two stages in form of hierarchic structure and moreover, (III) The optimal size of labor gang was obtained through dynamic programming from the point of minimizing the summation of labor gang in every stage, (IV) For the problem of optimal assignment, the optimal policy was determined at the point of minimizing the summation of movement between hatches.

  • This study examines the puzzle of institutional change of irregular worker protection system in Korea through a theory of incremental institutional change. It is the case of "conversion" mode of institutional change that occurs when ambiguous rules permit reinterpretations of rules and regulations for converting functions of institutions into new ones without formal revision. Management sectors with enforcement power have circumvented main rules of high discretion since 2007. In institutional dimension, the extent of irregular workers and the provisions of limit on employment-period and prohibition-correction on discrimination lack sufficient details. In political context, veto possibilities have been downward. Irregular workers were hardly organized independently and two labor union federations mainly composed of regular workers were less receptive to them. Veto possibilities in legislation were also low: the Economic and Social Development Commission ended up in weak labor representation and labor parties in the National Assembly have undergone dissolution.

  • The purpose of the study was to define the labor change in the moutainous villages, So this study analyzed the mass dram of the population from the mountainous villages created by the unequal development between the first and second under the high economic development and the large difference in the income between city and rural area. The content of the study was (1) the foundation of the production in the survey area (2) labor change in the mountainous villages (3) the supply and the demand of the labor in this area. The date were collected from 118 household of 2 villages (one with a high level of brest product, and the other with a low level of forest products) in Cheon-nam Province through a questionarie. The results of the study were as follows. 1. The mass drain in the mountainous villages started in the middle of 1970's, and the rate of drain has been very rapid and accelerated. 2. The drain of the mountainous village with a low level of forest products is more than that of the mountainous village with a high level of forest products. 3. In the mountainous village with high level of forest products, the specialization in the farmer class has begun and the farmers with a side job are now increasing. 4. Generally the major drain consisted of the young class (16-30 age), and consequently it caused a change in the composition of labor power into old age and women. 5. The character of the forest labor market is how changing from closed to open.

  • Recently, a long strike by hospital labor union emerged as a serious social issue. During the Worldcup Games in June, 2002, labor strikes broke up at 'C', 'K' and other hospitals, and in 2007, 'Y' hospital suffered much from a strike. Such series of extreme labor disputes have awakened people of importance of a more stable labor-management relationship for the medical institutions responsible for people's health than any other business organization. The purpose of this study was to examine the labor-management disputes at 'Y' hospital in 2007 and 'C' and 'K' hospitals in 2002. The results of this study can be summarized as follows; First, requests of the labor union such as pay raise, reemployment of the irregular workers as regular employees and participation of the labor union in personnel affairs are the long-held or core issues suffered by the medical institutions. Such issues are not independent from each other but complicated with each other surrounding the pay raise. Accordingly, it is not easy to determine the genuine bone of issue for labor-management disputes. Second, the model type of disputes between labor and management at medical institutions may be strike. However, it is conceived that the type of disputes would be subject to change as the essential medical service area system began to be operated since 2008. Third, the common characteristic of the labor strike among the 3 sample hospitals was occupation of the hospital lobby for a sit-in strike to maximize the negative effects of strike. Article 42 (Prohibition of Violence) of Labor Union and Labor Relation Coordination Act prohibits occupation of production or other important business facilities. In addition, since Ministry of Labor interprets that the hospital lobby belongs to the important business facilities enumerated by Article 42 of the above act, occupation of the hospital lobby for a sit-in strike may be too controversial to be admitted as a fair act of labor dispute when its legitimacy should be judged. Fourth, the counter-measures taken by the hospitals against the strike were observance of the principle 'no labor no pay,' closure, legal action, accusation, claim for recovery of damage, provisional seizure, disciplinary punishment, etc., but the principle of 'no labor, no pay' was not applied in a fair manner by 'C' and 'K' hospitals. However, 'Y' hospital applied this principle thoroughly to the strike; the hospital conduced to correction of the wrong labor-management relationship by refusing inclusion in the labor collective agreement of a provision about payment of wage during the period of strike or labor union's request to that effect during a strike. In addition, 'Y' hospital took an effective measure to end the strike earlier by notifying the labor union of cancellation of the collective agreement and banning the unionists from entering the hospital.

  • This study investigates the employment and spatial mismatch as a significant acting factor of deepening urban poverty and analyses the placeness of regional labor market that the more efficient place-based labor market intervention needs to take into account. The change of unemployment rate as a regional labor market outcome in metropolitan cities is determined by the dynamic interaction between disequilibrium of labor supply and demand and employment mismatch according to various labor market conditions and its process is certainly differentiated across the metropolitan regional labor markets. In addition, it is analyzed that during the employment suburbanization the spatial mismatch puts differentiated impacts on different labor groups through human capital requirements and industry-selective job opportunities. As a result, because this whole process works with its unique process within individual regional labor markets, in order to link between urban poverty and employment mismatch and to promote problem-solving labor market intervention, we need to develop place-based policy based on the placeness of regional labor marekt.

  • Purpose - Southeast Asia has been the focus of Korea's foreign investment. Korea has been helping developing countries in Southeast Asia achieve economic growth and win-win cooperation through capital exports. FDI is an important channel for technology diffusion. However, the impact of FDI on the bias of technological progress in the host country is dependent on the host country's own endowment structure and capital-labor factor substitution elasticity. Therefore, the central issue of this paper is to accurately evaluate the impact of Korea's FDI to the four Southeast Asian countries in various industries on their bias of technological progress. Design/methodology - The paper uses macroeconomic data for Korea and four East Asian countries to estimate capital-labor factor elasticities of substitution using nonlinear, seemingly uncorrelated regressions (NLSUR). Then, the biased technological change index (BTCI) is calculated for each country. Finally, panel data analysis is used to explore the impact of Korean FDI in various industries in the four Southeast Asian countries on their own directed technological progress, and a robustness test is conducted. Findings - There is a substitution relationship between capital and labor factors based on their elasticity in Korea, Singapore and the Philippines. There is a complementary relationship between capital and labor factors in Indonesia and Malaysia. According to the BTCI, there is a trend toward labor-biased technological progress in all countries. Korean investments in manufacturing, wholesale and retail trade in the host country trigger capital-biased technological change in the host country; investments in the finance, insurance and information and communication sectors trigger labor-biased technological change. In addition, this paper also confirms that directed technological progress can enable cross-country transmission. Originality/value - The innovation of this paper lies in three aspects. First, we estimate the BTCI for five countries and explore the trend and situation of directed technological progress in each country from each country's own perspective. Second, we explore the impact of Korean FDI in the host country on the bias to its technological progress at the industry level. Second, we explore the impact of Korean FDI in various industries in the four Southeast Asian countries on the four countries' own directed technological progress from a national perspective. Finally, we propose corresponding countermeasures for technological progress from the perspective of inverse factor endowment. These innovative points not only expand the understanding of technological progress and cross-country technology transfer in East Asia but also provide practical references for policy-makers and business operators.

  • This study aims to investigate the changes in the employment structure of occupational groups by job characteristics and analyze the factors influencing wage premiums in local labor markets from 2010 to 2020. This study's analysis involves three primary steps. First, the occupational characteristics data from the Korea Network for Occupations and Workers are subjected to an exploratory factor analysis, and then a non-routine task intensity index is calculated by each occupations. Then, we conduct an exploratory analysis of changes in the distribution of employment by occupation from 2010 to 2020 by combining data from the Population Census with data from the Korean Labor and Income Panel Study to construct individual-level and regional-level data. Thirdly, we employ a hierarchical linear model to examine the individual-level and regional-level factors influencing wage premiums. Since 2010, the proportion of employment in occupations requiring non-routine task has continued to rise and now dominates the metropolitan labor market. Moreover, agglomeration effects resulting from urbanization produce a substantial wage premium for wage workers in occupations requiring non-routine tasks. This study seeks to provide policy implications to mitigate inequality and polarization in local labor markets by empirically analyzing the transition of occupational structure and wage inequality in relation to the local labor market context.
