The purpose of this study was to analyze the results of 133 studies related to patient compliance published between 1980 and 2001 and to assess the effectiveness of intervention on compliance by using meta-analysis. We collected the existing literatures by using web and manual search 'patient compliance', 'sick role behavior', 'major clinical disease', and 'intervention' as key words and by reviewing content of journals related to medicine, nursing and public health. The compliance interventions were classified by theoretical focus into educational, behavioral, and affective categories within which specific intervention strategies were further distinguished. The compliance indicators broadly represent five classes of compliance-related assessments: (1) health outcomes (eg, blood pressure and hospitalization), (2) direct indicators (eg, urine and blood tracers and weight change), (3) indirect indicators (eg, pill count and refill records), (4) subjective report (eg, patients' or others' reports), (5) utilization (appointment making and keeping, use of preventive services). Quantitative meta-analysis was performed by MetaKorea program which was developed for meta-analysis in Korea. Among the 133 articles, 10 studies were selected through the qualitative meta-analysis process, and then only 6 studies were selected for the quantitative meta-analysis finally. The interventions produced significant effects for all the compliance indicators with the magnitude of common effect size (4.1192) than the non-intervention group in a random effect model. The largest effects were each study for patient of hypertension using health outcome such as blood pressure (0.4679) and diabetes mellitus using direct indicator such as glucose level in blood and urine (0.7753). These results suggest that strategic interventions showed clear advantage for improvement of patient compliance compared with non-intervention group.

This study was conducted to investigate the optimal management interval in 33 healthy adults by observing changes in oral health on the basis of the plaque control index and gingival index. When plaque control score was compared according to the period, it was found that oral hygiene management was the best in the fourth visit (p<0.05). Improved oral hygiene status was observed during the 3- and 6-month follow-up (p<0.05). Regarding gingival index, the fourth visit showed the healthiest gingival status (p<0.05). At the 3-month follow-up, the gingival index worsened, but a healthy gingival status was attained by 6-month follow-up (p<0.05). The plaque control score according to interest in dental health showed that the 'interested' group had good oral hygiene management (p<0.05). As a motivation for oral hygiene status and gingival health, examination with a 'phase contrast microscope' in the first visit and calculation of the 'evaluation index' in the follow-up visit tended to improve the patients' ability for oral hygiene management (p>0.05). The questionnaire survey showed, that the optimal management interval was 1, 3, and 6 months. As a result, with the effective management interval for the preventive management program focused on professional mechanical tooth cleaning, which was administered weekly, the maximum ability for oral hygiene management was attained at the fourth visit. The effective management period was 1 month. The use of a phase contrast microscope and the calculation of the evaluation index for oral hygiene management could influence the motivation to improve oral hygiene management.

Dietary intakes of 57 college women were measured by 7-day weight food records(7WR) Nutrient intakes of 7WR were compared with results of using 1-day weighted food records(1WR) and 2-day weighed food records(2WR), 7WR were recorded for 7 consecutive days by subjects and its first two days were chosen to provide 1WR and 2WR Mean nutrient intakes of the group were not significantly different between 1WR or 2WRand 7WR. Within-person variations were found to be greater than between-person variations. The ratio of within- and between-person variability was lowest for the vitamin A and highest for the calcium. Data on 7WR were analyzed to estimate the number of recording days needed to ensure r$\geq$0.9 between observed and turn mean intakes. The 11 to 13 days needed for energy sugar protein and vitamin A and 20 days for calcium The results indicated that the number of days needed varied substantially among individuals for the same nutrient and within individuals for different nutrients.

Purpose: To identify the epidemiological characteristics and risk factors of coronavirus disease 19 (COVID-19) outbreaks depending on the type of educational facility by analyzing the COVID-19 cluster associated with educational facilities. Methods: This study is based on epidemiological investigation of COVID-19 cluster in Gangwon-do, Korea from December 10, 2020 to September 23, 2021 reported to the Korea Disease Control and Prevention Agency's Integrated Disease and Health Management System. Four hundred seven patients in 19 facilities, classified as cluster related to educational facilities, were the study population. The result of preliminary epidemiology survey report, in-depth epidemiological survey by phone and the result of risk assessment derived from the field epidemiology investigation were retrospectively analyzed to evaluate infectivity and the characteristics of the risk factors. Results: There were total of 407 confirmed patients related to 19 educational facilities, with 204 students under the age of 19 (50.1%). One hundred fifty-five preceding spreaders were from families (38.1%) and 125 were the teachers (30.7%). The place exposed to confirmed patients was the highest with 139 people (34.2%) at home. Conclusions: It was confirmed that the cause of the occurrence of clusters related to educational facilities was higher due to family transmission than the risk of facilities in schools. Nevertheless, continuous efforts should be made to control infection in educational facilities, and that teachers' implementation of principles for prevention of COVID-19 personal hygiene in their daily lives should be strengthened.

Measuring intellectual capital efficiency is one of the greatest challenges for all who are involved in knowledge-based economy, at macro as well as at micro level. The purpose of this study is to calculate and analyze the efficiency of national intellectual capital and value added intellectual coefficient for Korea, US, Japan, and China during the period 2000-2005. Major findings from the analysis can be summarized as follows. The US shows both the highest value creation efficiency of national intellectual capital, 1.480 and the highest value added intellectual coefficient, 6.585. It holds rank one according to GDP per capita, $41,541 in 2005. In Korea, the coefficient of national intellectual capital efficiency is 1.321 while that of value added intellectual capital is 4.733. However, the national intellectual capital efficiency of Japan, 1.271 is in opposition to the created high of vale added, 5.695. Finally, China shows that the coefficient of national intellectual capital efficiency is 1.438 while that of value added intellectual capital is 3.815.

Purpose : To evaluate the effectiveness and tolerance of postoperative external radiotherapy for patients with intracranial meningiomas. Materials and Methods : The records of thirty three patients with intracranial meningiomas who were treated with postoperative external irradiation at our institution between Feb, 1988 and Nov, 1999 were retrospectively analyzed. Median age of patients at diagnosis was 53 years with range of 17 to 68 years. Sites of involvement were parasagital, cerebral convexity, sphenoid ridge, parasellar and tentorium cerebelli. Of 33 evaluated patients, 15 transitional, 10 meningotheliomatous, 4 hemangiopericytic, 3 atypical and 1 malignant meningioma were identified. Four patients underwent biopsy alone and remaining 29 patients underwent total tumor resection. A dose of 50 to 60 Gy was delivered in 28-35 daily fractions over a period of 5 to 7 weeks. Follow-up period ranged from 12 months to 8 years. Results : The actuarial survival rates at 5 and 7 years for entire group of patients were 78% and 67%, respectively. The corresponding disease free survival rates were 73% and 61%, respectively. The overall local control rate at 5 years was 83%. One out of 25 patients in benign group developed local failure, while 4 out of 8 patients in malignant group did local failure (p<0.05). Of 4 patients who underwent biopsy alone, 2 developed local failure. There was no significant difference in 5 year actuarial survival between patients who underwent total tumor resection and those who did biopsy alone. Patients whose age is under 60 showed slightly better survival than those whose age is 60 or older, although this was not statistically significant. There was no documented late complications in any patients. Conclusion : Based on our study, we might conclude that postoperative external beam radiotherapy tends to improve survival of patients with intracranial meningiomas comparing with surgery alone.

Class III malocclusion or anterior crossbite is commonly seen in Asian. This problem is easily recognized by dentists and parents. During the primary dentition period, anterior crossbite with functional shift and deep overbite could develop to skeletal protrusive mandible. So, early and proper diagnosis of anterior crossbite which needs prompt treatment is important. These cases showed the early management of crossbite with functional shift in primary dentition using intraoral removable appliance resulting in improvement of intermaxillary relationship. And I analyzed the positional change and the dimensional change during treatment with lateral cephalometric x-ray analysis. Our patients showed vertical dimensional change of lower anterior facial height and clockwise rotation which results crossbite correction in 1 year of treatment period.

With the effectuation of Kyoto Protocol on the United Nations Framework Convention on the Climate Change, the emission reduction of greenhouse gases became an urgent issue and has been competitively secured among countries as the form of certificates through clean development mechanism (CDM) or joint implementation (JI). Nitrous oxide ($N_2O$) is one of the major greenhouse gases along with carbon dioxide ($CO_2$) and methane ($CH_4$) having warming potential 310 times that of carbon dioxide and chemically very stable in the atmosphere to give a life time of more than 120 years so that it reaches to the stratosphere to act as an ozone depleting substance. $N_2O$ hardly decomposes and thus, besides to the adoption of thermal decomposition at high temperature, selective catalytic reduction methods are usually used at temperatures over $400^{\circ}C$ in which the presence of NOx acts as a major impeding material in the decomposition process. In this article, the sources of various $N_2O$ generation, catalytic reduction processes and the status and trends of emission trade with CDM projects for greenhouse gas reduction are summarized and discussed on a condensed basis.

The goal of this paper was to understand the skill-up experiences of ex-participants of the customized training program in Technical High Schools for Small and Medium Business during first 2 years in Company through qualitative interviews with 3 purposefully selected ex-participants. Their core skill-up experience in this period was assumed as the shift from' dependent worker' to 'independent worker' on the base of literature review. The results of this study were following : 1. The small and medium companies offered a few formal training for newcomers, production-site orientation through short job rotation, linking them with skilled workers and job manuals or job standards. 2. Authentic skill-up experiences were combined with a structured reprimand, peer learning, deep learning through reflection on one's own experiences. 3. There were a few handicap conditions that disturbed their skill-up activities: the skilled worker don't open their skill toward new corner; the ex-participants in company had no time to learn anything meaningful to up-grade their competency.

Purpose : The objective of this survey was to develop an operational plan for breast feeding education. In order to comprehend current breast feeding patterns, we aimed to examine the knowledge, attitude and practices regarding breast feeding of mothers and to compare the data with a similar study done 6 years ago. Methods : A total of 127 mothers who delivered healthy babies at Ewha Womans University Dongdaemun Hospital were interviewed and asked to complete a survey on their perception of breast feeding during their postpartum stay in the hospital. A follow up phone interview was carried out at 1, 2 and 3 months after delivery and similar questions were asked. Results : At the time of delivery, 96.1 percent of mothers planned to breast feed, including 73.2 percent of exclusive breast feeding and 22.8 percent of mixed feeding. The duration of breast feeding planned was mostly 7-12 months. Breast feeding had been recommended by family members. Between 1-3 months, exclusive breast feeding was maintained at least 50 percent but a large number of mothers who had practiced mixed feeding changed to formula feeding. This trend demonstrates an increase in the rate of breast feeding at 3 months compared to a similar study done in 1999. The main reasons for discontinuing breast feeding were insufficient amount of milk(35.0 percent) and return to work(27.5 percent). Conclusion : Breast feeding rate has increased in Korea since 1999 but failure to continue exclusive breast feeding still occurs mainly within the first month after delivery. Breast feeding education should focus on supportive care to mothers practicing mixed feeding.
