  • It is difficult to perform orthodontic treatment for cleft lip and palate patient. Although there are many orthodontic appliances to expand narrowed maxillary arch, results are rarely successful and the possibility of relapse is increased due to severe scars. Self-ligating bracket, recently used in orthodontic treatment, suggests solution of crowding by expansion of dental arches. Light and continuous force could apply for orthodontic movement due to characteristic low friction of self ligating bracket, which gives expansion force until dentition reaches its new equilibrium position and it can be expressed as spontaneous lateral expansion with heavy labial tension. This kind of expansion force is thought to be a possibility of expanding the constricted maxillary arch of cleft lip and palate patient. Repositioning of the maxilla by Le Fort I osteotomy in case of severe maxillary deficiency, increases the possibility of relapse because of limitation in anterior movement and adaptation of soft tissue. In these cases, distraction osteogenesis(DO) can be applied for stable result. We report a case of cleft lip and palate patient with narrowed maxillary arch and maxillary deficiency using self ligating bracket and DO.

  • In this paper, we consider a multilayer neural network, with a single hidden layer. Error backpropagation learning method used widely in multilayer neural networks has a possibility of local minima due to the inadequate weights and the insufficient number of hidden nodes. So we propose a fuzzy supervised learning algorithm by using self-generation that self-generates hidden nodes by the compound fuzzy single layer perceptron and modified ART1. From the input layer to hidden layer, a modified ART1 is used to produce nodes. And winner take-all method is adopted to the connection weight adaptation, so that a stored pattern for some pattern gets updated. The proposed method has applied to the student identification card images. In simulation results, the proposed method reduces a possibility of local minima and improves learning speed and paralysis than the conventional error backpropagation learning algorithm.

  • 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.

  • This study is performed to understand and resolve psychologically the issue of North Korea-South Korea's cultural heterogeneity which is treated importantly in unification debates. We collected data from 181 North Korea Defectors through survey, and found out that the North Korea Defectors perceived cultural heterogeneity so much especially at the early settlement stage. However, this fact itself didn't give a serious suggestion, What is significant was how much South Korean cultural orientation they had as a coping strategy. When they coped with South Korean cultural orientation, they showed high level of self-efficacy, and furthermore they demonstrated high level of psychological adaptation. By the way, this psychological adaptation level was not significantly correlated with positive index such as life satisfaction, but correlated with negative index such as depression. That is, low self-efficacy group showed high level of depression and 43% of them could be classified as a depression-symptom group. Thus, we can conclude that it is rather helpful for the North Korean Defectors to have South Korean cultural orientation for overcoming North Korea-South Korea's cultural heterogeneity, and coping strategy is more important than cultural heterogeneity itself.

  • Purpose: To survey the functional status, self-esteem and depression of a community of indwelling clients with total laryngectomy, and to evaluate the correlation among these three variances. Methods: From May 2002 to October 2002, 76 clients who had undergone total laryngectomy more than three months ago were surveyed with using Baker's functional status in head & neck cancer-self report, Rosenberg's self rating self-esteem scale and Zung's self rating depression scale. Results: 1. The functionaI status score was $48.67{\pm}10.12$. The subjects aged 70 years or older had significantly higher scores than the subjects aged $50{\sim}59$ years. The group of clients who were operated on more than five years ago showed higher scores than the patients operated on within a year. 2. The self-esteem score was $30.47{\pm}6.44$. 3. The depression score was $47.26{\pm}8.01$. The subjects who bad three family members and the subjects who had five family members had significantly higher scores than the subjects who had two family members. 4. A significant correlation found between the functional status and self-esteem. Significant negative correlations were found between the functional status and depression and also between self-esteem and depression. Conclusion: Remarkable correlations were observed among functional status, self-esteem and depression. Nurses should consider the status of layngectomy patients and pay more attention to their pre- and post- operative nursing care and rehabilitation.

  • The childbearing process is a sociocultural phenomenon of a woman who gives birth to a child as well as a biological phenomenon. The purpose of this ethnographic research study was to explore the experience of childbearing process of mothers with children from pregnancy to the 3 months postpartum in Korea and to understand deeply the perspectives of childbearing women reflected on Korean sociocultural values. A convenient sample of 10 childbearing women were observed from January to October 2000 through field work in Seoul, Korea. Data analysis was accomplished under ongoing process. The results of this study were as follows : The mothers with children experienced self-reflection, family relation, and physical adaptation during pregnancy. In self-reflection, all mothers experienced universality and diversity in their self-discovering process. The universal experiences were maturation, life with family and priority on maternal value between being a mother and a woman. The diverse experiences were taking a dual role of working mother, emotional drift of a resigned mother, and disheartened life of a mother who has two daughters. In family relation, the foundation of the new marital relationship were attained during childbearing process and sexual life were changed for the benefit of a healthy mother and a healthy baby. All mothers established friendly relations with their mothers, but established friendly or conflicting or constraining relations with their mother-in-laws due to husband based family culture. In physical adaptation, the informants endured well the physical discomfort and recognized general appearance change. Also maternal-fetal interaction occurred and mothers realistically felt motherhood and accepted themselves as mother-to-be. The mothers prepared for the best delivery, look for a safe childbirth center, newborn goods, endorsed family coping during hospitalization and responded labor pain to make it more endurable, less painful, fast passed owing to labor recognition of the natural process to be a mother. After childbirth, they felt emancipation, satisfaction, accomplishment, more easiness, actually feeling as mother-to-be, emptiness, and showed response to the sex of newborn. Their Sanhujori practice was different according to the Sanhujori environment including provider, place, time in postpartum and reflected on Sanhubyung. The mothers felt actually mother-to-be and happiness during lactation regardless of feeding pattern. These mothers had a different maternal image about rearing subjecthood through their child-rearing experience. But all mothers felt need for family support and social support. The universal rearing response were actual feeling of mother-to-be, a strenuous experience, a pride on child-rearing, confusion, reflecting marital relationship, and wondering rivalry among children. In conclusion, mother of all with children went through self-discovery, self-reflection and made connections with the family as a mother and as a woman simultaneously during the childbearing process. Therefore it is suggested when harmony and balance between a mother and a woman is accomplished, the woman will lead a healthy and high quality of life. Also, this study sought to confirm the sociocultural factors affecting the childbearing process from the perspectives of the women with children. Therefore health care providers must understand deeply the childbearing women with children based on this finding of and try a integrative approach with new ideology of maternity with biocultural perspectives in a clinical setting.

  • This study is a descriptive research study to grasp the critical thinking tendency, clinical practice stress, core basic nursing confidence, and degree of adaptation to clinical practice in nursing students. From June to July 2019, 207 students in the fourth year of nursing college were surveyed through their own questionnaire. Collected data were analyzed by t-test, ANOVA and multiple regression analysis using SPSS/WIN v24.0. The negative correlation between clinical practice stress and critical thinking tendency(r=-.18, p=.010). The core self-confidence practice self-confidence showed a positive correlation with critical thinking tendency(r=.25, p<.001), and a negative correlation with clinical practice stress(r=-.17, p=.017). Adaptation to clinical practice showed a positive correlation with clinical practice stress(r=.44, p<.001), and the factor influencing clinical practice adaptation was stress(β=.40) (F=18.34, p<.001), and the explanatory power was about 23.1%. As mentioned above, stress brings a positive change to clinical practice, so it is necessary to identify stress factors received from clinical practice of nursing college students and reflect them in curriculum development.
