  • Corpora annotated with lots of linguistic information are required to develop robust and statistical natural language processing systems. Building such corpora, however, is an expensive, labor-intensive, and time-consuming work. To help the work, we design and implement an annotation tool for establishing a Korean dependency tree-tagged corpus. Compared with other annotation tools, our tool is characterized by the following features: independence of applications, localization of errors, powerful error checking, instant annotated information sharing, user-friendly. Using our tool, we have annotated 100,904 Korean sentences with dependency structures. The number of annotators is 33, the average annotation time is about 4 minutes per sentence, and the total period of the annotation is 5 months. We are confident that we can have accurate and consistent annotations as well as reduced labor and time.

  • The purpose of this paper is two-fold. One is to investigate the determinants of the demand supply of labor, and another is to project long-term demand and supply of labor. The paper consists of three parts. In the first part, theoretical models and important hypotheses are discussed: for the case of a labor supply model, issues regarding discouraged worker model, permanent wage hypothesis, and relative wage hypothesis are examined and for the case of a demand model, issues regarding estimating an employment demand equation within the framework of an inverted short-run produc- tion function are inspected. Particularly, a theoretical justification for introducing a demographic cohort variable in a labor supply equation is also investigated. In the second part, empirical results of the estimated supply and demand equations are analyzed. Supply equations are specified differently between primary and secondary labor force. That is, for the case of primary labor force groups including males aged 25 and over, attempts are made to explain the variations in participation behavior within the framework of a neo-classical economics oriented permanent wage hypothesis. On the other hand, for the case of females and young male labor force, variations in participation rates are explained in terms of a relative wage hypothesis. In other words, the participation behavior of primary labor force is related to short-rum business fluctuations, while that of secondary labor force is associated with intermediate swings of business cycles and demographic changes in the age structure of population. Some major findings arc summarized as follows. (1) For the case of males aged 14~19 and 2O~24 groups and females aged 14∼19, the effect of schhool enrollment rate is dominant and thus it plays a key role in explaining the recent declining trend of participation rates of these groups. (2) Except for females aged 20∼24, a demographic cohort variable, which captures the impact of changes in the age structure on participation behavior, turns out to show positive and significant coefficients for secondary labor force groups. (3) A cyclical variable produce significant coefficients for prime-age males and females reflecting that as compared to other groups the labor supply behavior of these groups is more closely related to short-run cyclical variations (4) The wage variable, which represents a labor-leisure trade-off turns out to yield significant coefficients only for older age groups (6O and over) for both males and females. This result reveals that unlike the experiences of other higer-income nations, the participation decision of the labor force of our nation is not highly sensitive with respect to wage changes. (5)The estimated result of the employment demand equation displays that given that the level of GNP remains constant the ability of the economy to absord labor force has been declining;that is, the elasticity of GNP with respect to labor absorption decreasre over time. In the third part, the results of long-term projections (for the period of 1986 and 1995) for age-sex specific participation rates are discussed. The participation rate of total males is anticipated to increase slightly, which is contrary to the recent trend of declining participation rates of this group. For the groups aged 25 and below, the participation rates are forecast to decline although the magnitude of decrease is likely to shrink. On the other hand, the participation rate of prime- age males (25 to 59 years old) is predicted to increase slightly during 1985 and 1990. For the case of females, except for 20∼24 and 25∼34 age groups, the participation rates are projected to decrease: the participation rates of 25∼34 age group is likely to remain at its current level, while the participation rate of 20∼24 age group is expected to increase considerably in the future (specifi- cally, from 55% in 1985 to 61% in 1990 and to 69% in 1995). In conclusion, while the number of an excess supply of labor will increase in absolute magnitude, its size as a ratio of total labor force is not likely to increase. However, the age composition of labor force is predicted to change; that is, the proportion of prime-age male and female labor force is projected to increase.

  • The purpose of this study was to determine the standard work time of dietetic staff through work sampling methodology in school flood service systems. Work measurement through work sampling methodology was conducted in five conventional, five commissary and five joint management flood service systems over two consecutive weeks in October 1999. Statistical analysis was performed on the SAS/Win 6.12 package program for Kruskal-Wallis test and multiple comparison. Observed data were satisfied with a confidence level of 95% and a confidence interval of $\pm$ 0.05. The results of this study can be summarized as follows. The actual time spent by dietetic staff members in conventional, commissary, joint-management flood servile systems was 2,394, 2,521 and 2,110 minutes per week, respectively. Transportation time of each flood service systeml and ILO allowance rate (11%) was applied. Thus, the standard work time per week of dietetic staff members in conventional, commissary, joint-management flood service systems was 2,746.14, 2,861.58 and 2,520.81 minutes, respectively. The standardized index was 1.04, 1.08 and 0.95 men in conventional, commissary, and joint-management flood service systems, respectively. Regardless of the school flood service system, those with "the duty of cooking and distribution management" had the longest labor time, while those with "duty of nutritional education" had the shortest labor time.

  • The purposes of this study were to : a) investigate actual time spent and expected labor time spent on management activities, and b) develop standardized indices of dietetic staffing needs in employee foodservice. A job analysis questionnaires were developed and mailed to 65 dietitians who were members of The Korean Dietetic Association Practice Group, members with management responsibilities in employee foodservices. Completed questionnaires were received from 32 dietitians for a response rate of 49%. The questionnaire contained two parts with a total of 99 statements. Statistical data analysis was completed using the SAS programs for descriptive analysis, wilcoxon signed ranks test, wilcoxon rank sum test, and pearson correlation. The results of this study can be summarized as follows. 1. The actual time spent on management activities by dietitians in employee foodservice was 69.80 hours and expected labor time spent was 61.81 hours. And they were significantly different (p<0.05). 2. ILO allowance rate( 11%) was applied: The standardized working hours per week of dietitians working in employee foodservice with manufacturing and industrial plants, and office building were 79.61 and 64.25 respectively ; Staffing need indices were 1.81 and 1.46 respectively on the base of 44 working hours. 3. The average standardized working hours per week was 68.61 hours and staffing need indices was 1.56

  • Purpose: This study was to present improvement strategy and the problems of the nursing fee in national health insurance system. Methods: A total of 23 nursing activities performed by nurses were selected. Data were collected the relative value score and criteria of the Health Insurance Review & Assessment Agency. Sixty clinical nursing experts panels were composed and nursing time surveyed self-reported method. The actual fee was calculated through the nursing time, relative value score and actual labor costs. Nextly, the labor costs analyzed was compared with that in the national health insurance. Results: Although the practices were mainly performed by the nurse, other occupations have been recorded as main practitioners and the time of the nursing activity is partially improperly reflected. Additionally, although the nurse practiced mainly in glucose (semi-quantitative) test, it was confirmed that the principal practitioner was described as a clinical pathologist. The the labor cost gap was estimated that is 9.3 times (median) and 11.9 times (average) in this analysis. Conclusion: This study suggests that it is necessary to legislate a policy that can improve the quality of clinical nursing by reinforcing the appropriateness and improving nursing fee through reflection of the actual time spent for nursing care.

  • This study examines the impact of Long-Term Care Insurance(LTCI) on family caregivers(especially focused on female household members) labor supply in South Korea. When public care and informal care are substitutes, LTCI will change allocation of time of family caregivers to spend more time to paid work. The impact of LTCI on labor supply depends on each country's institutional level of public care services. If public care can not substitute for informal care, labor supply of family caregivers will not rise significantly. The conclusions of vigorous empirical study from western countries' are incompatible and problem of endogeneity in terms of methodology has been raised consistently. The dataset of this study are used the third and ninth waves of Korea Welfare Panel. As a result, the introduction of LTCI had no effect on labor supply of household members. Robust findings suggest the positive effects of caregiving on labor market outcomes in simple comparison t-test, but not in fixed-effect regression. Compared with western countries, South Korea's public care services can be interpreted as a supplement to only part that remained at the level does not substitute informal care. These findings may suggest that if LTCI become much more prevalent in the future, senior citizens and family members will be able to choose the LTCI arrangement that best suits their needs.

  • Co-residence is a type of intergenerational private transfers of resources: money, time and space. Adult daughters and their elderly parents decide to co-reside, depending on their utility levels before and after co-residence that mainly depend on the health status of the elderly. Therefore, co-residence implies positive net benefits to both parties in the sense that, when they co-reside, elderly parents share childcare and adult daughter provide elderly care. In other words, formal (paid) care can be substituted with informal (unpaid) one. Both marriage and giving births are considered as the major obstacles to labor market attachment of women who bear burdens of home production and childcare. Co-residence can be a solution for married women to avoid career interruption by sharing burdens with their elderly parents. However, most previous studies using the U.S. data on intergenerational private transfers focused on elderly care and have concluded that they reduce government expenditures associated with public subsidies to the elderly. This study focuses on adult daughters and it examines effects of co-residence on labor supply of married women in Korea, who face limited formal childcare programs in terms of both quantity and quality. It applies the Tobit model of married women's labor supply to the data from the Second Wave of the Korean Labor and Income Panel Survey( 1999), in order to investigate effects of co-residence and the work and health status of the co-residing elderly as well as their own health status. Four specifications of the empirical model are tested that each includes co-residence with elderly parents, their gender, or their work and health status. Estimation results show that co-residence, co-residence with female elderly, and co-residence with not-working female elderly have significant positive effects on labor supply of married women while poor health status of co-residing female elderly does not bring about any negative effects. However, co-residence with male elderly, regardless of their work and health status, has no significant effect The results indicate that co-residence is closely related to sharing of home production among female elderly and adult daughters who are married and, through intergenerational private transfers of resources in terms of time, it helps women avoid career interruption.

  • Today Korean clothing companies are experiencing difficulties in the global market due to unfavorable business conditions including poor production environments, labor shortage, rising costs, the further opening of the domestic distribution market, and increased competition among them. As a result, this has caused many of Korean clothing companies to transfer their production bases abroad in search of relatively inexpensive labor force, instead of using domestic plants. This study attempted to examine how Korean clothing companies perceive production environments and labor standards with regard to their offshore outsourcing. In such an attempt, in-depth interviews were conducted with 24 brand-name clothing firms. Those interviewed firms were the brands for the domestic or foreign market that were found to produce more than 200,000 pieces of clothing per year, and also the group of interviewees included some promotion service providers. The key findings from this study are as follows: First, a large number of the interviewed clothing companies were found to manage their foreign contract manufacturers by "visiting their factories regularly on a seasonal basis" or "stationing their personnel in factory for management purposes." Second, in relation to quality control in their foreign manufacturers, the most frequent response was to "have personnel stationed in those manufacturers." A smaller number of the clothing companies answered that they had "engaged their production management teams in quality control from time to time," or "used their inspectors to inspect products." Third, when asked about labor standards in foreign contract manufacturers, the largest number of the clothing companies responded, "we apply our own standards." The results of this study suggest that most of domestic clothing companies still use offshore sourcing just as a means of reducing their initial labor costs. However, in the continuously changing environment of the global clothing industry, clothing businesses are required to escape from the early phases of their manufacturing environments and set up more globalized standards.

  • The purpose of this study is to analyze the trend of changes in household labor among middle-aged generations who are facing dynamic changes in the middle of their life cycle. The research method is a literature study that examines and analyzes related data. Specifically, it aims to analyze the basic characteristics of middle-aged generations and trends in household labor, which are revealed through Time Use Survey, market trend reports, newspaper articles, and books. From the perspective of family resource management, housework is an unpaid activity performed by and for family members, and is an activity that can be replaced by purchasing goods or services from the market. This study focuses on the rapid growth of the home appliance market that replaces housework with the development of technology after industrialization, and how the change of technology affected the efficiency of housework. In addition, the composition and characteristics of middle-aged generations greatly changed according to changes in family structure, form, and family value. Examining the current state of housework and changing trends of middle-aged generations, which have different characteristics from previous generations, is significant in that it can predict future market trends and suggest implications for family policies that support the improvement of the quality of life of middle-aged generations.
