  • We analysed the determinants of part-timer labor demand and supply in Kwangju. The findings of the paper are as follows; First, firms employ part-timer workers in the unskilled or skilled jobs not demanding much training cost. There are two reasons for firms to employ part-time workers: labor cost cut and flexible employment adjustment. Estimated wage differential is 40% not including fringe benefits differential. Second, we find lots of married women to want part-time jobs. The more probably married women choose part-time work, the younger and the less educated they are, and the less kids and the less other income they have.

  • This article examines part-time work in the UK in terms of its characteristics and institutional contexts. Part-time jobs developed early due to the UK's liberal market institution and low level of public support for female employment. A large proportion of the employed women (about 40 percent) work part-time. Part-time work has been largely for married women. The expansion of part-time work in the UK was primarily market-driven and led by employers. Married women have worked part-time work primarily to accommodate their family responsibilities. There have been significant changes in labor market regulation in the UK since 1997. The Labor government legislated the Part-time Workers Regluations in 2000 to protect part-time workers. The government has also changed and newly implemented various laws and policies for work-life balance. There has been a real progress in improving the quality of part-time work overall. Nevertheless, we have not seen qualitatively different results in terms of female employment patterns and the qualify of part-time work so far. It has been largely constrained by the government's liberal orienation and voluntarism of labor relations in the UK.

  • The purpose of this study was to conduct the review of female labor suply, and thus, to provide useful theoretical and empirical frameworks for future studies related to female labor supply. Based on the theory of the allocation of time, the process of individual labor supply was systematically reviewed. Participation Probit/Logit, Tobit, and Selection B;ias Corrected Regression were considered in estimating the function of female labor supply which modifies the selection bias. Based on the previous empirical results, wage rate, asset income, husband's income, the level of eduction, and child-related variables such as the presence of child and the number of children might be considered for the empirical specification of female labor supply.

  • Objective: The purpose of this study was to examine the different effects on labor pain, length of delivery time, and hemoglobin for primipara women treated by San-Yin-Jiao(SP-6) acupressure of 15 minutes or 30 minutes. Methods: The design of this study was a randomized clinical trial with two experimental groups and one control group, the participants included primiparas who underwent vaginal delivery. Data were collected using a structured questionnaire consisting of general characteristics with a subjective labor pain scale with VA.S, and length of delivery time and hemoglobin were collected in the medical record. Data was analyzed using descriptive statistics, x2- test, t-test, and ANCOVA. Results: There was statistically significant lower labor pain in the group of 30 minutes SP6 acupressure than the control group(t=7.733, p=.007), and there was statistically significant short length of delivery time in the group of 15 minutes SP6 acupressure than the control group(t=-2.230, p=.030). Conclusions: Even though we could not found a consistent effect with the SP6 acupressure, It was found that there was effect on shortening length of delivery time by 15 minutes of SP6 acupressure or lessening labor pain by 30 minutes of SP6 acupressure without risk of blood loss. It is necessary to replicate the study with a larger number of participants to find a consistent result.

  • The purposes of this study were to analyze the structure of time use in farm households, and to compare the time use structure of women farmer with that of their husbands. The data for this study were collected from 276 farm households, selected from 8 provinces in the country. The data were collected at two times of farming season and off-farming season and classified as farm labor and household labor by labor types. SPSS(ver 12.0) statistical package was utilized to analyze the data, and t-test was performed for this study. The major findings are as follows; 1) In the case of work directly related to farming, husband's working hour was significantly longer than that of wife during the farming and off-farming season. In contrast with wife's household working hour was significantly longer than that of husband during both seasons. 2) There existed a severe work time imbalance between wife and husband during the-farming season. Based on the findings of this study, the following implications could be drawn to promote efficient labor and equal labor sharing. First, the consciousness has to be changed because the impartial labor sharing roles. We have to develope many programs to break these fixed ideas. And these programs have to be included to educational course and be instructed continuously. Second, the role of wife that household and farming work is important and will be magnified in the future.

  • The experiment was conducted to reduce the labor and production cost with the labor save of harvest in cultivating the onion using the machine and the results are as follows. On labor saving effect in transparent vinyl mulching, digging working hours per 10a in the case of using tractor are 55 min., fixing + turning time is 11 min.,the time of harvest is 66 min, digging working hours using cultivator are 90 min. and fixing + turning time is 9 min., but the time of hand harvesting is 693 min and 41 sec. and in digging labor saving effect, tractor shows 90% in the harvesting period and harvest by cultivator 86%. On nonmulching cases, the harvest by tractor takes 44 min. and that by cultivator does 75 min, and digging labor saving effect shows 93.6% in the tractor harvest and 89% in the cultivator harvest. Therefore, on the operation efficiency per hour, in the case of tractor with digger vinyl mulching and nonmulching show $0.091\sim0.136ha$ and in the case of cultivator with digger-both show $0.061\sim0.08ha$, but in the case of hand harvest, vinyl mulching and nonmulching are $0.008\sim0.009ha$, so in the mechanized harvest of onion, the harvest by tractor with digger is the best. On the cost and labor save for harvesting the onion with labor saving effect, tractor shows 19 hours and 26min./10a in vinyl mulching and 18 hours and 54min./10a in nonmulching, so it shows the short hours for harvesting. And labor saving effect shows 37% in comparison with 29 hours and 49 min. $\sim30$ hours and 38 min.($110,587\sim113,925won$) of the hand harvest, so the cost was reduced to $69,525\sim72,225won$. On the cultivator with diggers, vinyl mulching takes 19 hours and 49 min and nonmulching 20 hours and 2 min., so the labor saving effect and cost were reduced to $32\sim36%$($73,087\sim75,075$ won) in comparison with the hand harvest.

  • BIM is effective to improve the labor productivity of construction participants. From this point of view, it is important to analyze the outcome related with BIM Labor which covers most of the BIM investment costs. This research focuses on BIM RFI which is one of the major task of the BIM labor and analyze the outcomes. In addition, this research was quantitatively analyzed by the standby time and related cost caused by BIM labor, which affect the results of the project participants. To this end, analytical standby queue model was utilized to analyze the labor focusing on micros TASK. 11 projects were selected to analyze the results of BIM labor and RFI that the project participants requested to the BIM labor was collected. Through this, it collected variables for analyzing results, and Finally, we pulled out 4 projects for analysis. In this study, the basic results analysis of RFI processing of the BIM labor, the probabilistic analysis of BIM labor service status, and the economic analysis of BIM labor optimal inputs were performed by using the research model presented. The results of this study can be utilized to formulate the optimal strategy for BIM labor inputs(e.g. number of employees, level, time point, etc.) of the construction phase. Moreover, it can contribute to ensuring the credibility of the BIM ROI results by presenting the cost of BIM services in BIM ROI analysis and the standby cost of project participants.

  • Subject : The Imminent Labor Pulse(臨産 離經脈, extra-meridian pulse approaching labor) is one of many practical clinical knowledges, unique to Traditional Korean(Eastern) Medicine. Objective : This research explores the origin and change of perception on the subject throughout history, with objective to sort out practical knowledge applicable in the clinic of today. Also, it draws clinical meaning of pulse diagnosis according to the physiological theories, and suggests directions for future clinical researches. Method : First, the Imminent Labor Pulse was examined based on major publications such as the "Nanjing", "Maijing" and theories of major doctors. Second, this previous study was examined through clinical observation research. Third, further research was carried out on pulse theory according to the Traditional Medical theories. Fourth, their clinical practicality and points of further research were sorted out. These points need to be examined through additional clinical research. Conclusion : The following conclusions could be drawn from study of the Imminent Labor Pulse. From the Imminent Labor Pulse which indicated the beginning of the first period of labor in the "Maijing", it developed into trying to grasp the beginning of the second period of labor which is the actual time of labor, through "Zhubingyuanhoulun" and "Shizaizhifang". By Xueji, another pulse that could be felt on the middle finger of the mother had been discovered. The middle finger is where the Pericardium Meridian flows. The child's connection to the uterus becomes disconnected on the first period, but that with the Pericardium meridian which provides blood meridian to the Taichongmai of the child continues throughout labor until the umbilicus chord is cut. Therefore, this middle finger pulse could serve as showing the heart condition of the mother and child during labor. The time of its appearance and disappearance, and their correlation with the child's heartbeat need to be clinically examined.

  • The study examined the effects of San-Yin-Jiao(SP-6) acupressure treatment on labor pain, length of delivery and anxiety for women in the labor. The effects of using SP-6 acupressure were evaluated by comparing two groups, a SP-6 acupressure group (22) and a control group (17), for a total of 39 women in labor who had a normal vaginal delivery. Data were collected using a structured questionnaire which included general characteristics, a subjective labor pain scale, measurement of duration of delivery time and a subjective anxiety scale. Data were collected before treatment (pre) and after treatment (post). The results of this study are summarized as follows : 1. The post-scores for total labor pain increased over the pre-scores but the difference between the two groups was not statistically significant(p=0.219). Wilcoxon signed rank test of the difference in pre-post labor pain scores for the SP-6 acupressure group was not statistically significant (p=0.081) but the increase for the control group was statistically significant (p=0.001). 2. The length of time for the delivery in the group which had the SP-6 acupressure was shorter (143.91${\pm}$67.77) than the control group (197.94${\pm}$89.64). The difference between the two groups was statistically significant (p=0.028). 3. The post-scores for anxiety increased over the pre-scores but the difference between the two groups was not statistically significant (p=0.426). The scores of SP-6 acupressure group did not show a significant increase by the Wilcoxon signed rank test (p=0.194) but in the control group showed a significant increase (p=0.008).This study showed that SP-6 acupressure was effective in relation to labor pain, length of time for delivery and anxiety for labor women. But it is necessary to replicate the study with a larger number of participants to generalize the results.

  • The experiment is conducted to reduce the labor and production cost with the labor save of harvest if cultivating the potatoes using the machine and the results are as follows. On labor saving effect in transparent vinyl mulching, digging working hours per 10a in the case of using tractor are 60 min., fixing + turning time is 5 min. and 30sec., the time of harvest is 65 min and 30sec., digging working hours using cultivator are 99 min. and fixing +turning time is 5 min. and 30sec., but the time of hand harvesting is 990 min. and in digging labor saving effect, tractor shows 94% in the harvesting period and harvest by cultivator 90%. On non mulching cases, the harvest by tractor takes 49 min. and 30 sec. and that by cultivator does 87 min. and 30 sec., and digging labor saving effect shows 94% in the tractor harvest and 90% in the cultivator harvest. Therefore, on the operation efficiency per hour, in the case of tractor with digger vinyl mulching and non mulching show, $0.091\sim0.121ha$ and in the case of cultivator with digger both show $0.057\sim0.069ha$, so in the mechanized harvest of potatoes, the harvest by tractor with digger is the best. On the cost and labor save for harvesting the potatoes with labor saving effect, tractor shows 19 hours and 20 min./10a in vinyl mulching and 19 hours. and 54 min./10a in non mulching, so it shows the short hours for harvesting. And labor saving effect shows $42\sim45%$ in comparison with 35 hours and 21 min. $\sim35$ hours and 23 min.($123,113\sim130,613$ won) of the hand harvest, so the cost was reduced to $71,250\sim72,225$ won. On the cultivator with diggers, vinyl mulching takes 19 hours and 55 min. and non mulching 19 hours and 38 min., so the labor saving effect and cost were reduced to $14\sim44%$ ($72,675\sim73,313$ won) in comparison with the hand harvest.
