  • Purpose: This study was carried out to show the parental child-rearing attitudes perceived by daughters(woman college students), who were in the process of pursuit of resonable values, ethics and preparing for marriage and settling down, and another purposes were to help them to have positive attitudes toward their child-rearing in the future and set up preliminary parenting education program. Method: The subjects were 120 woman college students who were freshmen to junior in one university in Seoul. Using the self-report questionnaire, data were collected from December in 1999 to March in 2000. The contents which subjects wrote down were categorized by content analysis method. Result: 1) The age range of subjects were 19-25 years old and main rearer was mother(85.84%). 2) The perception of parent's child-rearing by subjects were revealed 555 statements and then tied together 50 themes: 'emphasizing on studying hard'(8.3%), 'doing by oneself'(5.6%), 'sternness'(5.2%), 'respect of personality'(4.5%), 'eagerness'(4.0%), 'humanity education'(4.0%), 'moderating in daily living'(4.0%), 'propriety education'(3.8%), 'sacrificing for children'(3.6%), 'expectation'(3.2%), 'concerning'(3.1%), 'parent-centered'(3.1%), 'giving a free hand'(2.9%), 'sharing with'(2.9%), 'consideration'(2.7%), 'over-protectiveness'(2.3%), 'hostile attitude' (2.2%), 'corporal punishment'(2.2%), 'expression of parental love'(2.0%), 'encouragement'(1.8%), 'family-centered' (1.8%), 'treating fairly'(1.6%), 'offering live experiences'(1.6%), 'exacting obedience'(1.62%), 'exemplary parental role' (1.6%), 'sexual discrimination'(1.6%), 'cooperation'(1.4%), 'giving favors'(1.4%), 'indifference'(1.4%), 'understanding' (1.3%), 'confidence'(1.3%), 'intimacy'(1.3%), 'pursuit of health'(1.3%), 'warm-hearted'(1.1%), 'stinginess'(1.1%),'broad-mindedness'(0.7%), 'granting'(0.7%), 'interfering'(0.7%), 'reproach'(0.7%), 'distinction of sex in household affairs'(0.7%), 'help'(0.5%), 'preparing for the future'(0.5%), 'disregarding'(0.5%), 'making environment'(0.4%), 'bringing up a child personally' (0.4%), 'comparing'(0.4%), 'religious life'(0.4%), 'good deed'(0.4%), invasion of privacy' (0.2%), 'controlling desire'(0.2%). 3) 50 themes were categorized by 18 categories once more: 'control' (13.2%), 'crazy for education'(12.3%), 'endeavoring'(8.6%), 'autonomy'(8.5%), 'home education'(7.7%), 'esteem' (6.67%), 'support'(6.67%), 'pursuit of healthy daily life'(5.6%), 'earnestness'(5.4%), 'disregarding personality'(5.4%), 'emotional bonding'(3.2%), 'imposing a burden'(3.2%). 'inhospitality'(3.1%), 'acceptance'(5%), 'discrimination'(2.3%), 'mature parenthood'(1.8%), 'strengthening family tie'(1.8%), 'psychological intimacy'(1.1%). 4) On the basis of this study, 3/5 of subjects(61.2%) perceived their parents had mature and autonomous child-rearing attitudes, and on the other hand 2/5(39.5%) of them perceived controlling, just forcing to work harder and personally disregarding attitudes. Conclusion: So we need to offer them nursing implementation such as preliminary parenting education program and parenting consulting like to strengthen positive perception and help improving in realistic, developmental child-rearing attitudes.

  • The Archaeological sites of so called Round Clay Rim Pottery (Jeomtodaetogi : 점토대토기) culture in Kangwon region have been rarely excavated in proper form. Since most cases belong to those of ground surface gatherings, it is difficult to certify the nature and the association with other artifacts. Therefore, researches on that culture have been limited to simply set the chronological order in the Bronze Age in realtion with the Plain Pottery culture. However, a comparative study trying to explain the Round Clay Rim Pottery culture in both Yeongseo(영서) and Yeongdong(영동) has become possible thanks to recent excavation results from the sites of Chilgeon-dong(칠전동) in Chunchon City(춘천시) and Songrim-ri(송림리) in Kangneung City(강릉시), for example. Certain difference can be observed in form and amount of artifacts in between Yeongseo and Yeongdong. Such difference can be seen as individual localization in different places diffused from a common source, rather than showing different stages of unilineal developmental process of one culture. The Round Clay Rim Pottery culture seems to have been coexisted with the Rim-Perforated Pottery(공렬토기) and Dolmen(지석묘) culture. According to the radiocarbondatings, the upper time limit of the Round Clay Rim Pottery culture goes back considerably beyond the alleged upper limit of either the late fourth century or the second century B.C.. However, both cultures absorbed into the Iron Culture during the same period.

  • Purpose: Maxilla and mandible have different patterns of cortical and trabecular bone and different bone mineral densities, even though both are components of the jaw bone. However, cellular differences between maxilla- and mandible derived osteoblasts (OBs) have rarely been studied. We hypothesize that maxilla- and mandible-derived OBs show different responses to $17{\beta}$-estradiol (E2), which is one of the critical factors for bone formation. This study compares skeletal site-specific cell responses between maxilla- and mandible-derived human OBs to E2. Methods: Maxilla- and mandible-derived OBs derived from an identical donor were separately isolated from a total of five normal healthy subjects aged 18~44 years old, cultured with a treatment of 100 nM estrogen. The responses between maxilla- and mandible-derived OBs to E2 were evaluated and compared using cell proliferation, alkaline phosphatase (ALP) activity and gene expression of osteoprotegerin (OPG), ALP, insulin-like growth factor-1 (IGF-1), and estrogen receptor ${\alpha}$ ($ER{\alpha}$). Results: E2 did not have any distinct effects on the proliferation of both types of OBs. Mandible-derived OBs exhibited higher ALP activity than maxilla-derived OBs in the non-treated condition, which was common in all tested individuals. ALP activities of both types of OBs showed a minor increasing tendency with the treatment of E2, even though there was no statistical significance in some specimens. The gene expression of OB by E2 was diverse, depending on the individuals. There was increased expression of OPG, IGF-1, or $ER{\alpha}$ gene in the part of subjects, which was more repeated in maxilla-derived OBs. In particular, OPG or ALP induction by E appeared less frequently in mandible-derived OBs. Conclusion: Current results revealed that E2 affects maxilla- and mandible-derived OBs into facilitating the osteogenic process despite individual differences. Mandible-derived OBs are less sensitive to bone-forming gene expression by E2.

  • This study, was done to compare the nursing education systems of China and South Korea (Korea), then, on the basis of this comparison, to examine the direction of nursing education in China. The results the study are as follows : 1. Nursing education in Korea was influenced by social change, political policy, but as it was established, nurses in Korea, were able actively involved in presenting nursing education development proposals to the government, and in developing nursing education through their own efforts. Nursing education in China developed through the political policy of a socialist Country. During the period of modernization after 1977, a nursing education developed very quickly, In 1983, the first baccalaureate nursing education program was established and, in 1992, the first masters program was opened. 2. In Korea, there are two nursing education systems; diploma and baccalaureate, and there is only one entry level, high school graduation. In China today, on the other hand, there are three types of nursing education systems; technical, diploma, and baccalaureate, and they have middle school and high school graduation as the two levels of entry. 3. There are similarities between China and Korea in curriculums for nursing education which include the major nursing concepts. But in descriptions of the education objectives, China the emphasis is on training the 'expert' in clinical nursing which is not consistent with their educational philosophy. Korea differs from China in that the focus is on training for 'multiple ability' to be used in both clinical and community environments. 4. In Korea, the curriculum is organized with the theoretical and clinical experience combined. The curriculum is oriented to the life cycle and human developmental process. In China, however, the curriculum is organized so that after finishing the theoretical part of the curriculum, the students begin a one year intensive field experience in which the major clinical field is the hospital, and the focus is on disease oriented care and research ability. 5. In order for nurses to be proposed to address nursing education system needs follows : to change as The new nursing education system should be baccalaureate education in order to improve the education level in all nursing education programs, to develop doctoral programs, to open nurse specialist programs, and to develop a new curriculum based nursing philosophy and health delivery system change. New nursing curriculum for health care in China in the 21st century should be directed by a framework based on nursing philosophy, objectives and nursing content. In conclusion, the study will contribute China nursing education system revolution for policy develop and curriculum research. According to these results, in the future, nurses in China should be more actively involved in research and in a nursing education revolution, Also they should be involved in building information networks and in developing long term projects in nursing education.

  • The purpose of this paper is to analyze the structure and characteristics of the utilization support systems(USS), which has been institutionalized to aid the use of social welfare services in Japan's social welfare systems recently. In order to conduct such purposes, this paper made the process as follows. Firstly, this paper examined the developmental processes of social welfare systems, and the back ground of institutionalization of USS in Japan. Secondly, this paper formulated at ideal dimension the analytic model which was to explain the structure and characteristics of the USS. To build this model, this paper used two factors which were the connective dependency to the welfare support systems and the feasible-satisfying alternative setting for user. Thirdly, this paper analyzed the characteristics of the user-driven support facilities which has already activated in social welfare systems in Japan. According to the result of analyzing such model, this paper explained that USS in Japan has possessed the structure and characteristics, such as to aid self actualization and human right of user, to compose the inner coalition organization with supply systems, to emphasize the employee to train care management's skill, and to keep up bounded openness to USS's participation. Therefore, oligopoly market is formulated owing to bounded openness in the field of USS and the role of social worker such as a care manager is emphasized on making care plan.

  • Developmental process of vegetation over years after afforestation was analyzed in the Japanese larch (Larix kaempferi) plantations with different stand ages. The height and diameter of Japanese larch increased rapidly until 24 years after afforestation and tended to be blunted thereafter. The density of Japanese larch was similar with each other in the 8 and 17 years old stands but was reduced greatly in the 24 years old plantation and changing little thereafter. The floristic composition of the Japanese larch plantation did not show any clear trend depending on stand ages. The differences of species composition among plantation themselves with different ages were bigger than those between plantations and the reference stands, Mongolian oak (Quercus mongolica) stands. Japanese larch plantations showed a trend of succession to native vegetation dominated by Mongolian oak based on the results of analysis of frequency distribution by diameter class of major tree species. Species richness and diversity of all plantations were higher than those of the reference vegetation. As were shown in the above mentioned results, it can be evaluated that Japanese larch plantations practiced in the level of the functional restoration achieved successful restoration based on the floristic composition similar to the reference vegetation, the successional trend toward native vegetation, and higher species diversity compared with the reference vegetation.

  • Different factors may affect the sensitivity of porcine oocytes during cryopreservation. The effect of two methods (cooling and vitrification), four cryoprotectants [glycerol (GLY), 1, 2-propanediol (PROH), dimethyl sulfoxide (DMSO) or ethylene glycol (EG)] and two vitrification media (1 M sucrose (SUC)+8 M EG; 8 M EG) on the developmental capacity of porcine oocytes at the germinal vesicle (GV) stage or after IVM at the metaphase II (M II) stage were examined. Survival was assessed by FDA staining, maturation and cleavage following IVF and IVC. A toxicity test for different cryoprotectants (GLY, PROH, DMSO, EG) was conducted at room temperature before cooling. GV and M II-oocytes were equilibrated stepwise in 1.5 M cryoprotectant and diluted out in sucrose. The survival rate of GV-oocytes in the GLY group was significantly lower (82%, p<0.01) than that of the other group (92 to 95%). The EG group achieved a significantly higher maturation rate (84%, p<0.05) but a lower cleavage rate (34%, p<0.01) than the DMSO group and the controls. For M II-oocytes, the survival rates for all groups were 95 to 99% and the cleavage rate of the GLY group was lower than the PROH-group (21 vs 43%, p<0.01). After cooling to $10^{\circ}C$, the survival rates of GV-oocytes in the cryoprotectant groups were 34 to 51%, however, the maturation rates of these oocytes were low (1%) and none developed after IVF. For M II-oocytes, the EG group showed a significantly higher survival rate than those of the other cryoprotectant groups (40% vs 23-26%, p<0.05) and the cleavage rates of PROH, DMSO and EG group reached only 1 to 2%. For a toxicity test of different vitrification media, GV and M II-oocytes were equilibrated stepwise in 100% 8 M EG (group 1) and 1 M SUC + 8 M EG (group 2) or equilibrated in sucrose and then in 8 M EG (SUC+8 M EG, group 3). For GV-oocytes, the survival, maturation and cleavage rates of Group 1 were significantly lower than those in group 2, 3 and control group (p<0.05). For M II-oocytes, there were no differences in survival, maturation and cleavage rates between groups. After vitrification, the survival rates of GV and M II-oocytes in group 2 and 3 were similarly low (4-9%) and none of them matured nor cleaved after in vitro maturation, fertilization and culture. In conclusion, porcine GV and M II-oocytes do not seem to be damaged by a variety of cryoprotectants tested, but will succumb to a temperature decrease to $10^{\circ}C$ or to the process of vitrification, regardless of the cryoprotectant used.

  • The lysosomal acid hydrolases including lysosomal acid phosphatase (LAP) are believed to play an important role in intracellular and extracellular degradation. LAP was reported to increase its activity in dedifferentiation stage during urodele limb regeneration. In the paresent study, LAP localization in the Mexican axolotl (Ambystoma mexicanum) limb regenerates was investigated by immunohistochemistry. LAP immunoreactivity with monoclonal antibody against Korean salamander (Hynobius leehii) LAP was observed mainly in the wound epidermis, blastema cells, muscle, and cartilage which were under dedifferentiation process in axolotl limb regenerates. Moreover, LAP immunoreactivity increased gradually during the early phase of lib regeneration and reached the peak level at dedifferentiation stage. However, as redifferentiation begans, LAP immunoreactivity decreased slowly to the basal level. Retinoic acid (RA) which is known to induce skeleton pattern duplication in regenerating urodele limb appears to enhance LAP immunoreactivity. In the RA-treate limg regenerates, LAP immunoreactivity was higher than in the normal regenerates. In addition, the LAP expression period was more extended in the RA treated regenerates than in the normal regenerates. These results suggest that RA is involved in the extension of dedifferentiation state in RA-treated limb regenerate.

  • The present experiment was performed to confirm the effects of selenium on maturation and viability of mouse oocyte. Maturation of oocytes was observed by microscope, Germinal vesicle breakdown(GVBD) and polar body formation(PB) were confirmed at 2.5, 13 hours after in vitro culture. Viability of oocytes was observed by microscope. Normal and abnormal oocytes were distinguished by morphological change in vitro culture for 72 hours. Glutathione(GSH) content of collected oocytes from individual stage also was measured by glutathione assay using spectrophotometer. The results obtained were as follows; The low concentration of selenium($0.005\;{\mu}g/mL{\sim}0.5\;{\mu}g/mL$) increased the maturation rate of germinal vesicle(GV) oocytes to GVBD and PB oocytes. The high concentration of selenium($5\;{\mu}g/mL$) decreased the maturation rate. The low concentration of selenium increased the viability rate of PB oocytes. The high concentration of selenium did not affect the viability rate. The low concentration of selenium increased the GSH content in PB oocytes. The high concentration of selenium decreased GSH content. GSH content in PB oocyte was much higher than that in GVBD oocyte. The results indicate that the low concentration of selenium increases the maturation rate by helping quality elevation of oocyte and minimizing damages of oxidative stress generated from metabolism process. The low concentration of selenium also increases the viability rate by increasing GSH content.
