  • The lifting scheme has been found to be a flexible method for constructing scalar wavelets with desirable properties. In this paper, it is extended to the UDAR data compression. A newly developed data compression approach to approximate the UDAR surface with a series of non-overlapping triangles has been presented. Generally a Triangulated Irregular Networks (TIN) are the most common form of digital surface model that consists of elevation values with x, y coordinates that make up triangles. But over the years the TIN data representation has become an important research topic for many researchers due its large data size. Compression of TIN is needed for efficient management of large data and good surface visualization. This approach covers following steps: First, by using a Delaunay triangulation, an efficient algorithm is developed to generate TIN, which forms the terrain from an arbitrary set of data. A new interpolation wavelet filter for TIN has been applied in two steps, namely splitting and elevation. In the splitting step, a triangle has been divided into several sub-triangles and the elevation step has been used to 'modify' the point values (point coordinates for geometry) after the splitting. Then, this data set is compressed at the desired locations by using second generation wavelets. The quality of geographical surface representation after using proposed technique is compared with the original UDAR data. The results show that this method can be used for significant reduction of data set.

  • Objectives : The purpose of this study was to apply informations related to herbal medicines to IDMP (Identification of Medicinal Products), an ISO standards related to medicinal products substances, for systematic collection of data through the integration of informations on distribution, manufacturing, and management of herbal medicines. Methods : By analyzing ISO 11238 and ISO/TS 19844, elements that can be used in the information model of herbal medicine were derived from the identification of medicinal products information model on substances. The labeling specified in the safety and quality control regulations for herbal medicines was mapped to the IDMP information model, and ginseng was applied as an example. Results : Herbal medicine corresponded to substance in IDMP. Among the five types of substances specified by IDMP, herbal medicines were expressed as structurally diverse. Scientific name was used as an invariant property of herbal medicine, and the substance level included information about source material and modification, and specifically included information about the scientific name, medicinal part, fraction, and processing. In addition, the specified substance level had information on the constituents, characteristic attributes, manufacturing, and grade of the herbal medicine. Conclusions : It is necessary to establish a code system for identifying herbal medicines. In order to apply the IDMP standards, research on the development of standard terms is required to express the characteristics of herbal medicines. In addition, information for identification of herbal medicines is also required, and information from production to consumption should be systematically accumulated and managed for actual application.

  • Purpose : The purpose of this study is to directly understand the health condition of residents of mental health sanatoriums nationwide, which has been difficult to ascertain in surveys conducted to date. The study presents specific measures for improving the health of these residents. Methods : A "physical examination questionnaire for residents of mental health sanatoriums" was developed to check the basic physical condition of residents, and 20 out of 59 mental health sanatoriums nationwide were randomly selected. Medical personnel visited the sanatoriums, interviewing and examining the residents in person. A total of 396 health surveys were completed. Results : Many of the residents were underweight but had abdominal obesity. It was confirmed that chronic diseases among the residents were not diagnosed early or were not properly managed. Among the subjective symptoms complained of by the residents, musculoskeletal symptoms were the most common. Oral examinations revealed a serious level of oral health problems among the residents, including dental caries and missing teeth. Basic physical examinations found health problems that required additional examination or medical treatment. Blood pressure abnormalities made up the highest percentage of the health problems. Conclusion : Regular health surveys are needed to determine the health condition of residents of mental health sanatoriums. Access to and quality of primary medical services within the sanatoriums need to be dramatically improved. A delivery system for severe diseases and emergency medical care in the sanatoriums should also be specifically presented. The residents should be notified upon admission and during their stay that they have the right to the enjoyment of the highest attainable standard of mental and physical health. The issue of health rights should be addressed within a larger framework of reorganizing management plans for people in the community - not only residents - with chronic mental illness.

  • Purpose : The purpose of this study was two-fold: to identify the effect of dental hygienist's self-determination motivation on their job engagement and to analyze the moderating effect of compensation satisfaction that affect the relevance. Methods : Data were collected using a structured self-report questionnaire administered to 260 dental hygienists working in dental hospitals and clinics in Busan, South Korea. These were analyzed using IBM SPSS Statistics version 26.0 and SPSS Process Macro 3.5. A frequency analysis, including the respondents' general characteristics, frequency, percentages, and standard deviations, was performed. A regression analysis was also performed using SPSS Process Macro to verify the moderating effect of compensation satisfaction in the effect of self-determination motivation on job engagement. Results : The self-determination motivation of the dental hygienists had a statistically significant positive effect on their job engagement, which was the dependent variable. Higher intangible compensation satisfaction levels led to a stronger effect of intrinsic motivation but a weaker effect of extrinsic motivation on job engagement. Moreover, higher tangible compensation satisfaction levels strengthened the effect of intrinsic motivation on job engagement. Conclusion : Recently, the demand for oral health care has been increasing, Competition in the dental medical service market warrants, high-quality dental services based on accurate diagnosis and treatment. In this context, dental hygienists' job engagement must be improved. For this purpose, increasing the satisfaction of dental hygienists with self-determination motivation and appropriate compensation is effective. In addition, attention must be paid to the moderating effect of compensation satisfaction on the relationship between intrinsic motivation and job engagement. On the basis of the implications of this study, the results can be used as basic data for improving dental hygienists' welfare system and manpower management.

  • In this study, the authors surveyed the dietary habits of all elementary school students registered with the Busan Metropolitan City Office of Education using an online questionnaire called the Dietary Screening Test (DST). The DST consists of 36 items, and these were divided into 5 factors: life rhythm, meal quality, eating development, eating temperament characteristics, and eating habit characteristics. Data were collected from 153,017 students attending 304 schools in Busan, and the responses of 4,020 were included in the analysis. The study was undertaken to document growth and development and diagnose nutrition and dietary problems to provide basic data for the development of customized nutrition education and counseling programs. Results showed that 13.5% and 14.3% of participants were classified as overweight or required weight management for obesity, respectively; 6.7% were underweight. Additionally, 37.0% and 9.5% of children required parental attention at bedtime and sleeping hours, and 14.2% ate too quickly or too slowly. Furthermore, food group consumptions were unbalanced, 25.0% and 64.4% of participants ate grains and protein less than twice a day, respectively, and 72.3% and 74.5% ate kimchi and vegetables less than twice a day, respectively. In contrast, 28.8% of respondents consumed sweet snacks daily or 5~6 times weekly. These findings highlight the need for a standardized school nutrition counseling manual and individually customized nutrition counseling programs to address the nutrition and dietary problems of elementary school students in Busan.

  • Purpose : The objective of this study is to serve guidelines for the investigation and management of uterine myomas with KM therapies. Methods : English-language articles from PubMed and Korean-language articles from the database of the journal of oriental gynecology were reviewed from 2000 to 2005, using the key words 'uterine myoma', 'uterine leiomyoma', 'fibroid', 'uterine artery embolization', 'endometrial ablation', 'myomectomy', and jagungguenjong(子宮筋腫)'. Results and Limits : The areas of clinical practices considered in formulating this guideline are assessment, KM therapies, medical treatments, myolysis, selective artery occlusion, endometrial ablation and surgical therapies including myomectomy and hysterectomy. Implementation of this guideline would optimize the decision-making process of women with uterine myomas and further investigation or therapy of their KM doctors. But we don't have abundant evidences of clinical trials of uterine myoma treated with KM therapy, though we treat or manage that with every-day clinical practices. Moreover cultural gaps between Korea and other western countries make many differences in the attitude to surgical therapies, especially hysterectomy. So it is very difficult to compare W therapies with other therapies. Moreover it is much difficult to estimate cost-effectiveness and benefit of those therapies in QOL. Conclusions : The majority of uterine myoma is asymptomatic and will not require any intervention or further investigation. But unmarried women who wish to marry and get pregnant want to find safe therapy for their asymptomatic uterine myomas. In that case, most of the patients prefer non-surgical therapy to surgical therapy. So KM herbal medicinal therapy is a good alternative method for those patients. For the symptomatic myomas, hysterectomy offers a definitive solution. However, it is not the best solution for women who wish to preserve their uterus. So KM therapy is a good alternative for them. But the predicted benefits of alternative therapies including KM therapy must be carefully weighed against the Possible risks of these therapies. To improve the quality of life of both women with asymptomatic and symptomatic myomas, selecting and treating patients should be done carefully. Moreover, the effect of KM therapy has to evaluated, comparing the possible situation without treatment and the benefit of constant treatment as a health-care system.

  • Purpose: Physician's occupational burnout has been a very important issue that can cause negative consequences not only for individual's physical and mental health, but also for patient's health and the overall national healthcare system. For the reason, this study confirmed how consultation length and the number of outpatients affect physician's occupational burnout in the medical environment. Methodology: In the study, the data of '2020 Korean Physician Survey' conducted by Korean Medical Association(KMA) was used for the analysis, and a total of 4,215 physicians were selected as study samples. The differences in the degree of occupational burnout according to the physicians' general characteristics were confirmed through uni-variate analysis, and also a regression analysis was conducted to confirm the effects of consultation length and the number of outpatients on physician's occupational burnout. Findings: As a result. the overall degree of physician's occupational burnout decreased(𝛽=-0.051, p<0.01) as the consultation length increased. Specifically, the physician's emotional exhaustion increased(𝛽=0.051, p<0.01), while the reduction of accomplishment decreased(𝛽=-0.131, p<0.001). Furthermore, the overall occupational burnout decreased(𝛽=-0.047, p<0.01) as a proportion of advice and education during the consultation increased, and it had an effect on the decrease in depersonalization(𝛽=-0.045, p<0.01) and the reduction of accomplishment(𝛽=-0.065, p<0.001). At last, as the number of outpatients increased, the overall occupational burnout increased(𝛽=0.041, p<0.05) with more emotional exhaustion(𝛽=0.095, p<0.001), depersonalization(𝛽=0.065, p<0.001), and less reduction of personal achievement(𝛽=-0.081, p<0.001). Practical implication: Consequently, it is necessary to prevent physician's occupational burnout by ensuring sufficient consultation length and providing a medical environment to treat an appropriate number of patients. Therefore, national policies should expand health insurance coverage and compensate medical fees for sufficient consultation length that both patients and physicians can satisfy. It will ultimately contribute to ensuring the patients' health and improving the quality of national healthcare services.
