I. Preface A. Establishment. There are many psycological and physiological difficulties that students have made practical application to a building site of 600 pyung and a structure of 65 pyung each sixteen students in the Home Management House, but there exists problem in students apprentice and management of professors. B. Purpose of study This research aim to seek a high degree of efficiency approach in investigating, studying and analyzing factors of the problem in Home Management which have been faced in women colleges in seoul. C. Content of study. This study is aim at finding out the problems including facilites, system, guiding principle, working bottleneck and administrative problem in making practical application of Home Management. II. A plan and method of study A. This subject of statiscal research is 616 women students in senior year from september 27 1970 to October 31 1974. The rate of collection of questionnaire is 100 percent. B. The Method of study is devised through refering documents, interview with students, questionnaire and observation. III. Result of study Of the total of 29 university in seoul, 24 Universities have its Course of Home Economic among which only 12 have Home Management for making practical application. Home Management House for making practical application is located mainly in campus but some of them exceptimally are in outside university. Students practice mainly at civilzed resident, apartment, bangalow so forth, and demention of which occupies approxiamtely 50-600 pyung (land) and 20-70 pyung (Building). A member with 4 or 20 students make practical application from 10 days to 3 months. A member consists of students and assistant teacher, and practice site classifies into living school for Professors living, and another school for Professors and assistant teachers. Answer to a questionnaire. 616 students answer to a questionnaire. 49 Perfect of 616 students like to have a member with 12 students like to have a member with 12 students, 38 percent student a member with 16 students. About the period of making practical About the period of making practical application, 76 percent students like to have two or three week period. 19 percent students think it a short period and 4 percent students think it a long period. There is none who thinks 25 day period day period to be short. About making practical application, 66 percent of 616 students feel uneasy, 40 percent students feel lack of sleep and tired. Students take a pleasure in having a conversation with their friends, inviting their mother, having dinner-party and birthday party. 77 percent students want to invite their father and 67 percent students want to invite their boy-friends. It is hard to have a good personal relation about the great the result of practice, students acknowledge themselves that they have learned about Cautiousness and they are sure of good Home Manager. There are 9 difficult problems during the period. IV. Summary discussion a. Many problems come from having a number of students. b. Students feel tired with their practice if over three weeks. No Matter how good a plan is, it useless if students can't adapt themselves to it. Suggestions 1) it is good to have a member with 5 or 6 students, and it is suitable to have two or three week period, and to have an area of 20 or 30 pyung. 2) it's proposed a profess or to live together in making practical application of Home Management 3) it is proposed a professor to have a sure T.O. and to be treated better.

This study explored the processes of parental divorce and adaptation in single-parent families as well as examined how the experience of living in family welfare facilities influences the adaptation process of such families. The research question to achieve the study objective was, "What is the adaption process for a singlefather family, and what influence does living in a single-father family welfare facility have on that process?" Data collection was conducted between June 2013 and April 2014 that included an in-depth interview process and continuous participatory observations on 14 children residing in the facility. The study results were as follows. The theme in a two-parent family period was 'changes in reduction of family: serious conflicts between parents.' Children directly witnessed intense conflicts between parents and experienced anxiety from situations that involved verbal and physical violence during the two-parent family period. The experience of children prior to entering the facility was represented by "loss and confusion experienced." The theme for children of singlefather family in entering a facility was "selecting a realistic alternative." Children's daily activities consisted of being with friends of a similar age, which allowed them to play and support each other in building social skills. The facility departure theme for the children was "hope for a new life."

The concentration of gaseous elemental mercury (Hg) was measured concurrently with relevant environmental parameters from Yang-Jae monitoring station in Seoul during Sept. 1997 to June 2002. Although data collection was disrupted for certain periods, the grand mean concentration of Hg for this five year period was found at 5.32 $\pm$ 3.53 ng m$^{-3}$ (N = 27,170). Because of short resolution of data acquisition, we were able to examine the temporal variability of Hg at varying time scale. The diurnal variability of Hg, when investigated for each of those five years, indicated consistently the dominance of nighttime over daytime. If examined at seasonal scale, Hg level was systematically higher during winter/spring than summer/fall period. The results of this short-term variability were best explained by the combined effects of such factors as meteorological conditions (formation of inversion layer and seasonal changes) and anthropogenic source processes. However, examination of long-term variation Pattern was much more complicated to explain. Thus, extension of our study is needed to diagnose the future direction in long-term trend of Hg behavior.

Purpose: This study was to identify predictors of sexual function in gynecologic cancer patients. Methods: The participants were 154 patients treated at a university medical center in A city, Korea. The data collection was performed through a structured questionnaire from July to December, 2010. The instruments used in this study were Female Sexual Function Index (FSFI) perceived health status scale, Eastern Cooperative Oncology Group (ECOG) performance status, body image, and depression. Data were analyzed using descriptive statistics, Mann-Whitney test, Kruskal-Wallis test and stepwise multiple regression with the SPSS 18.0. Results: The mean score of perceived health status was 8.42 and sexual function was 8.42. The lowest score among sexual function was lubrication. The scores of sexual function was significantly different by age, job, marital status, period after diagnosis of cancer and diagnosis. There were significant correlations between sexual function, perceived health status, ECOG performance, body image and depression. In multiple regression analysis, predictors were identified as ECOG performance, age, diagnosis and period after diagnosis of cancer (Adj.$R^2$=.28). The most powerful predictor of female sexual function was ECOG performance (19.0%). Conclusion: The above findings indicate that it is necessary to develop a more effective and personalized sexual function improvement program for gynecologic cancer patient.

The objectives of this study were to identify the period of initiation of floral primordia in black locust (Robinia pseudoacacia L.) and subsequent development of floral buds until following spring. Four mature trees of black locust located in Suwon, Korea were selected. Bud samples were collected from the current-year shoots, starting from mid June to July every week, from August to October and from February to April every month. The buds were fixed in FAA solution, dehydrated, and imbedded in paraffin for microscopic observation. Buds collected on June 16, and 23, 1997, contained primitive primordia that might be interpreted as early floral primordia. By June 30, a bud showed a positive indication of inflorescence primordium with a well-formed shoot apex. All the inflorescence primordia observed throughout the collection periods were always associated with unique hairy appendages around the primordium and enclosed within a sclerenchymatous chamber. By July 7 and 15, a floral apex had early bud scales. By July 22, primitive inflorescence developed into visible arrangement of individual floral primordial By July 29, the inflorescence developed into whirl arrangement of individual floral primordia in a transverse section, but showed little further development until October 15. The inflorescence primordia seemed to over-winter at this stage. Buds collected from February 15 and March 24 the following year also showed no further development of inflorescence primordia. By April 7 the inflorescence started to show further development with elongated axis. At this time individual flowers were easily recognized.

First half of my article focused on analyzing the current state of historical materials regarding weather and climate, and established a list of weather-related historical literature collection of Korea with which to make a lexical approach to the situations of all kinds of weather literature. It also put emphasis on gathering information and data of weather logs from journal-type historical records which were contained in 48 weather-related journals of Choseon period. The results of this research are expected to be useful for the activation of study in historical meteorology. The latter half of my research focused on analyzing various meteorological states of sunny, cloudy, rainy, snowy and frosty weather which were recorded in the official Annals of King Kojong (1864~1907). And it re-verified historical rainfall data of preceding researches of Wada Yuji (1917), Jung-Lim (1994), Jhun-Moon (1997). In result, different records were found between data of theirs and mine. It means that we have to analyze and reconstruct newly the meteorological data of the Annals of King Gojong and the Daily Records of Royal Sungjungwon (1623~1910) during the late Choseon period.

The purpose of this study is to explore practices of the child rearing in the late period of the Goryo Dynasty. This study was using the historical method and the materials for analysis were the literatures written from the late thirteenth century to the fourteenth century in Goryo Dynasty, such as 'the Ikjaijip'(익재집), 'Mokeunjip'(목은집), 'Yangchonjip'(양촌집). According to the results, parents, grandparents, maternal grandmother, and an elder sister played important roles in child-rearing. And parenting roles were expected to give their children affections and consistent disciplines. In terms of sustenance for children, children were provided with boiled rice as principal food and seasonal fruit and rice cake as snacks. In housing habits, children, especially boys, shared the same room with their grandfather. And children were assured of physical safety and psychological protection through cultural practices, such as taboo, prayers, humble naming, first birthday celebration, and dreams of forthcoming conception. Finally, disciplining of children was focused on studies for Confucianism and shaping basic habits for cultivation of mind.

This study was carried out to investigate the effects of diverse dietary Ca levels and to determine whether bone mineral metabolism is influenced by the arnount of dietary Ca when given a choice of diets containing various levels of Ca. Forty Hy-line brown laying hens housed in separate cages were fed self-selected Ca diets. Birds were allowed a 7-day adaptation period followed by an 8-day collection period. Feed and water were available for ad libitum consumption. Eggs and excreta were collected at 6-h intervals during the day for mineral analysis. The Ca contents in excreta and retained Ca in the body on egg forming day were proportional to the amount of daily Ca intake. The retained Ca in the body were 0.97 g in control and 1.24~1.74 g in self-selected groups, respectively. Daily Ca contents (%) in tibial cortex were not consistent with feeding time intervals. The Ca content in tibial medulla in control group was lower than those of self-selected feeding groups(P<.05). The medullary Ca content in all treatment groups increased from 10:00 to 16:00 in a day. Ca content in plasma was low between 10:00 and 16:00 and was high between 22:00 and 04:00 in the following day.

Present study examined the effect of intermittent versus continuous infusion of progesterone(P) on LHRH release in uiuo from the mediobasal hvpothalamus of ovariectomiEed, estradiol-primed adult rats bearing push-pull cannulae. Three experimental groups were studied: 1) control (perfusion medium only),2) intermittent perfusion of P (10-min on,20-min off, and 3) continuous perfusion of p. p (10 ng/mll was directly infused into the MBH following a 3 hr basal collection. Perfusates were collected at 10 min intents린s on ice and LHRH release was measured by LHRH radioimmunoassav. Cycle detector analysis revealed that the spontaneous HRH output in the control group was pulsatile over a 7 hr push-pull perfusion period. The mean basal LHRH release, pulse amplitude and pl서se period were 0.68 $\pm$ 0.03 ps110 min, 1.15 $\pm$0.08 pg and 60 $\pm$ 9 min, respectivelv. Intermi구eat perfusion of P clearly stimulated the mean LHRH release (pre-P vs post-P: 1.14 $\pm$ 0.18 vs 1.99 $\pm$ 0.53 pg) without changes in LHRH pulse frequency. In contrast to intermittent infusion of p, continuous administration of P faithed to modify LHRH release, since the mean LHRH release and pulse amplitude between pre-P and post-P perfusion urere similar. The in vitro study clearly showed that intermittent, but not continuous administration of P is effective in stimulating LHRH release. Therefore, it appears that rhythmic secretion of P mal be the erective signal for activating the neural LHRH apparatus.

Segmentally erected prestressed concrete box girder bridges have been widely used in Korean high speed railway. Segmental erection has been accomplished along the longitudinal direction and across the depth of cross section. The cross section is similar to a composite cross section, composed of old and new segments. Because these segments have different time-dependent creep and shrinkage properties, a stress redistribution takes place during the construction period. It is the main objective in this research to investigate this behavior. An actual bridge was instrumented with 96 vibrating wire embedded type strain gauges, 6 electronic type steel strain gauges, and 75 thermocouples. Two span continuous high speed railway bridge was selected. Two points of importance, such as the midpoint of the first span and the point of interior support, along the span of the girder were chosen to monitor the time dependent behaviors for an extended period of time. The data collection was starting just after concrete girder were cast and is still going on. According to the measured results, the strain distributions across the depth of the section at midspan and interior support were not continuous and the important redistribution of stresses takes place. Thus, rational design of prestressed concrete composite box girder bridges need.
