  • The purposes of this study are to identify the types of teacher efficacy, to present a theoretical base for teacher efficacy among Home Economics teachers and subsequently, to improve the quality in the practices of home economics education. To achieve these purposes, 263 secondary school home economics teachers were surveyed by the prime investigator. The three research questions of this study were: 1. What are the individual characteristics, the environmental characteristics and the trends of teacher efficacy among secondary school home economics teachers? 2. What is the factor in teacher efficacy among secondary school home economics teachers? 3. What are the types of teacher efficacy among secondary school home economics teachers? For these research questions, factor analysis and cluster analysis were conducted. The factor analysis on teacher efficacy with a survey of secondary school home economics teachers produced 5 factors of efficacy: classroom management, needs assistance, instructional strategies, environmental assistance and teaming assistance. The teacher efficacy had a mean of 3.58 and the home economics teachers showed a slightly higher level in teacher efficacy. Of the 5 efficacy factors, classroom management showed the highest level (M=3.89), followed by learning assistance (M=3.81), instrumental strategies (M=3.57), environmental assistance (M=3.42) and needs assistance (M=3.19). Overall, the teachers had positive feeling in teacher efficacy. Three types of teachers were found in the types of teacher efficacy: the supreme, the average and the efforts-needy. Those types were identified based on the mean scores of the five sub-domains from the factor analysis. To enhance the teacher efficacy, the needs assessments for the students and behavioral adjustment issues should be reflected in the curriculum of teacher education and workshops. The primary investigator suggested that continuous and long-term plans for teacher education need to be developed because short-term plans may not be effective in changing attitudes such as teacher efficacy.

  • Objectives: To evaluate the methodological quality of Korean Acupuncture Clinical trials Methods : Two independent researchers reviewed 12 protocols of Acupuncture clinical trials which were conducted in Korea 2006. Also, Survey Principal Investigator of those was conducted. We compare the results of protocol review with investigator reponses of actual practice. Quality assessment consisted of 5 items including random sequence generation, randomization method, allocation concealment, subject blinding, assessor blinding. Results : Randomization was performed using the proper procedure to insure that treatment assignment is unbiased and concealed from subjects in all clinical trials, According to protocols, 6(50%) of 12 clinical trials used computer-generated random numbers, 6(50%) remaining trials didn't describe the randomization method. Also all trials used appropriate randomization methods on the basis of the survey results: 8 trials used computer-generated random number, 2 used random table. Of 7 protocols in which allocation concealment was stated, 5(71%) reported appropriate method (Calling a central office or statisticians, Sealed opaque envelopes). However according to survey, 5(42%) of 12 trials used inappropriate allocation concealment (Keeping a master randomization list and referring to when subject entered the trial). In addition, the result of protocol review and survey response was not coincident in 5(42%) trials. Subject blinding was conducted in all except 1 clinical trials. Although 11(92%) of 12 trials were conducted using assessor blinding in actual practice, only 7(58%) reported that in protocol. Conclusion : Although randomization and blinding were conducted adequately, allocation concealment was used inadequately, Not only appropriate allocation concealment, but also every quality assessment item including randomization, blinding should be stated in more detail in protocol.

  • The purpose of this study was to identify concretely how to improve inquiry learning. To put the purpose in detail : 1) to define the inquiry skills 2) to select the factors of inquiry skills appropriate to the content of Science I (earth science) textbook 3) to develop items which consist of experimental inquiry and concept inquiry in due proportion, to evalute inquiry skills 4) to analyze the relationship between high school students' cognitive levels and the achievement of science inquiry skills. To achieve these objectives, the investigator sampled 558 students in eleventh grade, living in Seoul, Chung-Ju and Kwang-Ju, and evaluated their cognitive levels and the achievement of science inquiry skills. The results of this study showed that the cognitive levels of students were lower than those identified in Piaget's work and that the achievement of science inquiry skills were low also. It may be thought that one of most important reasons to bring about those results is lacking in adaptation capability of science inquiry items and inquiry learning. So, it can be recommended as a way to heighten cognitive levels to make inquiry learning using the textbook content. In conclusion, the investigator make suggestions as follows : 1) to give inquiry learning which consist of experimental inquiry and concept inquiry in due proportion 2) to develop inquiry items to include content for evaluating inquiry learning, and test items for psycho-motor areas 3) to publish textbooks which motivate students' inquiry activities and develop their creative thinking, considering students' cognitive levels and inquiry skills.

  • Background: The characteristics of lateral epicondylitis (LE) are muscle strength weakness and increased common extensor tendon (CET) thickness. Ultrasonography has recently been used to evaluate tendinopathy. Diamond taping (DT) is commonly used to manage patients with LE. However, no previous studies have investigated the effects of DT on CET thickness. Objects: The aim of this study was to investigate the effects of DT applied around the lateral elbow on CET thickness, grip strength, and wrist extension force in healthy subjects. Methods: The subjects were 26 adults (13 male) in their twenties. First, the CET thickness was measured at rest. The CET thickness was measured by using ultrasonography at two points. The subjects were then instructed to perform maximal grip activities or maximal wrist extension activities before and after DT around the lateral elbow. The DT technique was applied using non-elastic tape. While the subjects performed maximal grip activities, the investigator measured the maximum grip strength (MGS) and CET thickness. Likewise, while the subjects performed maximal wrist extension activities, the investigator measured the maximum wrist extension force (MWEF) and CET thickness. Results: The MGS showed a statistically significant improvement after DT taping application in men (p < 0.05). The MWEF showed a statistically significant improvement after DT application in male (p < 0.01) and female (p < 0.05). When performing the activities, the CET thickness increased compared to that at rest. However, CET thickness didn't show a statistically significant improvement before and after DT. Conclusion: This study shows that DT applied around the lateral elbow is effective in improving MGS and MWEF. However, it does not affect CET thickness.

  • This research was an attempt to make it possible to provide nursing care and health education meet- ing the need not of care givers but of patients by identifying the nature of patients' self regulation experiences. The specific objective of this study was : 1) to explore self regulation experiences of patients with adult disease. The phenomenological approach in qualitative studies is used to serve this purpose. Colaizzi's method is used for the phenomenological analysis of the data in this study, which were collected from 25 patients hospitalized in the internal medical ward and oriental medical ward of a Seoul hospital, suffering from adult disease such as hypertension, arteriosclerosis and diabetes mellitus. The research was conducted over a period of March to September, 1994. The investigator conducted participated observations and in-depth unstructured interviews which were audiotaped under the permission of patients. The investigator read the data repeatedly to identify and categorize significant statements, formulating meanings, themes and theme clusters. The result is categorized as follows : Self regulation activities, their barriers and predisposing factors of a disease. Thirteen theme clusters of self regulation activities related to health identified were. “maintaining diet regimen”, “maintaining exercise regimen”, “maintaining medication regimen”, “maintaining oriental medical regimen”, “maintaining health monitoring regimen”, “maintaining self effort”, “maintaining religious life”, “maintaining social sup-port systems”, “maintaining peaceful mind”, “maintaining moderation in life”, “maintaining sincere attitude in life”, “maintaining natural life”, and “maintaining folk remedy” This findings confirm the fact that self regulation is complicatedly and diversely influenced by oriental medicine and folk remedy, and Korean traditional ideas melted in Confucianism, Buddhism, Taoism and Shamanism, and modern medical care and western culture. Seven theme clusters of self regulation barriers identified were : "lack of knowledge and self aware-ness", "lack of social supports", "lack of awareness of need in continuous regimen and treatment", "dissatisfaction with hospital and health care provider", "lack of self management ", "lack of will to combat illness", and "overconfidence in folk remedy" Four theme clusters of predisposing factors of a disease were : "cumulation of stressors", "fatalism", "careless life style", and "family history". In conclusion, this. study will prove helpful not only in understanding clients in light of our traditional culture but also in providing them with the kind of nursing care and health education satisfying their demands and particularly cultural needs.

  • Exposure to the sun, ultraviolet radiation, and oxidative stress are the chief etiologic factors responsible for melasma. The ingredients of Korean red ginseng powder, which include ginsenoside and phenolic compounds, have antioxidative effects and reduce ultraviolet B-induced pigmentation. This study was designed to evaluate the effectiveness and safety of Korean red ginseng powder in patients with melasma. In 25 female patients, 3 g of Korean red ginseng powder was orally administered for a 24 week period. The level of pigmentation and erythema were determined and clinical improvement was evaluated by the melasma area and severity index (MASI), melasma quality of life scale (MELASQoL), and patient- and investigator-rated global improvement scale. After 24 weeks, the MASI score decreased from 8.8 to 5.6, and MELASQoL showed improvement in 91% of patients (p<0.05). The mean level of pigmentation decreased from 184.3 to 159.7 and erythema levels decreased from 253.6 to 216.4 (p<0.05). Additionally, 74% of the patients showed some improvement in both patient- and investigator-rated global improvement scales at week 24. Korean red ginseng powder was well tolerated by most of the patients. In conclusion, Korean red ginseng powder showed good tolerability and beneficial effects in patients with melasma. The use of Korean red ginseng would be counted as a useful adjunctive therapy for patients with melasma.
