Objectives: The suicide rate in Korea is increasing every year, and is the highest among the Organization for Economic Cooperation and Development countries. Psychiatric patients in particular have a higher risk of suicide than other patients. This study was performed to evaluate determinants of mental health care utilization among individuals at high risk for suicide. Methods: Korea Health Panel data from 2009 to 2011 were used. Subjects were individuals at high risk of suicide who had suicidal ideation, a past history of psychiatric illness, or had utilized outpatient services for a psychiatric disorder associated with suicidal ideation within the past year. The chi-square test and hierarchical logistic regression were used to identify significant determinants of mental health care utilization. Results: The total number of subjects with complete data on the variables in our model was 989. Individuals suffering from three or more chronic diseases used mental health care more frequently. Mental health care utilization was higher in subjects who had middle or high levels of educational attainment, were receiving Medical Aid, or had a large family size. Conclusions: It is important to control risk factors in high-risk groups as part of suicide prevention strategies. The clinical approach, which includes community-based intervention, entails the management of reduction of suicidal risk. Our study identified demographic characteristics that have a significant impact on mental health care utilization and should be considered in the development of suicide prevention strategies. Further studies should examine the effect of mental health care utilization on reducing suicidal ideation.

The arguments exist that private health insurance(PHI) policy holders tend to use the health care services more than non-policy holders due to their little out-of-pocket spending, resulting in the adverse effects on the finances of National Health Insurance. This study aims to increase the objective understanding of the issue and to draw a direction of further research, by reviewing the articles, reports and statistics which examined the effects of purchasing PHI policies on health care utilization. Significant differences in healthcare utilization, except for the very partial increase of utilization in outpatient settings, have been not found. The similar trends of the results have existed in a few previous studies which tried to control the endogeneity of medical use and health insurance with latent variables which affect the decision on medical use and health insurance. However, we can not exclude the potential change of healthcare utilization patterns because the portion of the insured of indemnity PHI is becoming rapidly larger in the market. For further research, we should try to obtain the objective information of subjects' past medical history, health status, health related behavior, and income affecting purchase of PHI and utilization of healthcare services. And the efforts of controlling the endogeneity of medical use and health insurance with latent variables which affect the decision on medical use and health insurance, are very considerable.

Objectives : This study was carried out to know the status of clinical utilization of Korean medical knowledge and the Korean medical knowledge system which Korean medical doctors want. Methods : Questionnaires were distributed to Korean medical doctors registered for the Association of Korean medicine via the email and 249 answered questionnaires were analyzed. Results : 50.6 % of Korean medical doctors utilized the textbooks for Korean medicine when they treated their patients. The reason why they did not utilize the textbooks for Korean medicine was mostly that 'it could not be applied directly into clinical application with only contents of textbook because clinical approach (diagnosis and treatment methods) was not clearly described in the textbook'. 48.6 % of Korean medical doctors utilized the EBM materials when they treated their patients. EBM materials that they referred included domestic articles, other EBM materials excluding papers and international academic papers based on PubMed in order. The reasons why they did not utilize the EBM materials were mostly that 'it was difficult to find the evidence' and 'EBM materials were not actually helpful for the clinical practice.' It was found that Korean medical doctors approached the disease in aspects of Korean and Western Medicine concurrently upon the diagnosis of patients and performed the diagnosis and treatment of Korean medicine on the diseases which seemed to be effective with Korean medicine. It was also found that they thought that they needed to know the Western medical knowledge as much as general doctors who have a doctor's license or family medicine specialists who comprehensively treat the general diseases know. Korean medical doctors wanted to have the systematic summary of modern research performance in fields of acupoint, acupuncture, herbal drugs and formula. They thought that constitutional medicine and Sa-am acupuncture therapy were representative characteristics in Korean medicine differentiated from Traditional Chinese medicine and Kampo medicine. Conclusions : Korean medical doctors wanted to establish the Korean medical knowledge system based on evidence focusing on clinical and practical contents. New Korean medical knowledge system should be established based on these requirements in the future.

The historical records of public institutions are not only important historical records for the study of modern Korean history in various academic fields such as politics, economy, society, culture, and science, but also important historical content that students and the public may be interested in. In this study, among the 350 institutions designated as public institutions as of 2021, 339 public institutions that can request information disclosure through the information disclosure portal were investigated. Based upon the results of the survey, it was found that 217 (67%) out of 326 (96.2%) public institutions compiled a total of 516 institutional histories. This study proposed improvement plans in terms of the compilation of history in public institutions and the utilization of users by analyzing the results of the investigation of the compilation status of history in public institutions by six elements: compilation time, target period, department in charge, budget and required period, accessibility, and regulations.

It is rare that the dwelling buildings designated as cultural assets owing to the demands of the rapid-changing times and their residences are conserved as their original shapes, though the extent varies. Meanwhile, there has been a continuous effort to preserve and take over our traditional dwelling culture. Yet, the effects were not tangible because the viewpoints are different between the conservation promoters and related residents-officials-experts and because the conservation method is not decided in advance. Thus, in conserving the traditional dwelling culture containing the history of human life, this study tries to find out the reasonable ways for conserving traditional residence based on the consciousness research of citizens on conserving and utilizing the cultural assets. Furthermore this study also tries to suggest to contemporaries - who should live side by side with the historic cultural assets - what attitude they should have. On the basis of above survey, the objective of this study is said to consist in presenting the directions - what efforts are needed - for the more active and participant conservation.

A new possibility for helping regional residents to establish the identity based on the history, culture and environment of the region and harmonizing art and culture in daily life can be seen from eco-museum. Unique cultural inheritances for each region exist not only in our nation but everywhere around the world, and Cheonan region is continuously attracting tourists from other regions as a home of the Independence Hall, Yu Gwan Sun Memorial, and live branches of independent activists with important inheritances such as tourist attractions and national treasures. However, despite unique environment of the region and inheritances with high academic values, lack of basic guides and explanations place the region in an environment that is difficult to approach. The purpose of this study is to systematically investigate regional inheritances based on the concept of eco-museum as an alternative for such problem recognition and to examine problems of inheritances scarred around Cheonan region based on their current status. The author of this study aims to analyze the investigated regional inheritances, rearrange their values and suggest possibilities for continued preservation and utilization.

This study was carried out in order to find out an effective machinery utilization strategy by conducting a survey on utilization and maintenance of agricultural machinery. The survey showed that the no. of utilization hours for power tiller in a year was 190.2hrs, 208.6hrs for tractor, 59.1hrs for rice transplanter, 74.0 hrs for combine, 44.6 cultivator and 254.4hrs for 4.4hrs for grain dryer. The period covered the time the machine was until it became unserviceable. The results are as follows: 10.0yrs for power tiller, 7.5yrs for tractor, 7.4yrs for rice transplanter and 5.4yrs for combine. This indicate that the actual period of use for power tiller and rice transplanter was longer than the expected period of duration years so there is a need for adjustment. The factors considered by the farmers for purchasing agricultural machine were: farm size(32%), machine operation (26.0%), performance(l4.0%) and post or after sales service(12.6%), according to the survey. It showed that repair cost rate in a year was classified into major agricultural machine; 4.8% for combine; 3.9% for tractor; 3.5% for rice transplanter; 2.0% for power tiller; 1.6% for grain dryer; and 1.2% for cultivator. The reasons for poor maintenance were insufficient after sales service(25%) and difficulty in buying parts(75%) because of the unavailability of parts in local shops(55%), imported models(30%) and outmoded model(15%).

As a result of this study, an attempt to emphasize the effect of perspective through the factors of spatial constitution is considered that, in Mwaeom thought, the establishment of the basic situation for cherishing the religious experience as Seonjae Dongja's course of ascetic practice, was needed. Therefore, placing of gates, terrace make-up and the changing spaces and constitution that the space under a castle moves from narrow darkness to wide brightness, express the steps of the course of ascetism. Through this, it gives observers dramatic changes and expectation to their sensual feeling. The emphasis on the perceptibility of Muryang Sujeon, Anyang Loo and the terrace by using a perspertive technique can be interpreted as an intention to express the very delightedness at the last moment the truth is perceived.

Radiographic examinations are used to discover and define the type and extent of disease in many clinical situations. Currently, it is common for dental patients to receive dental radiographic examinations on a routine schedule with little variation in spite of different patient signs and symptoms. Such routine scheduling of radiographic examinations may result in unnecessary patient exposure. There is also the possibility of under-utilization of radiography; this can result in inadequate or excessively delayed diagnosis. Patient selection criteria are descriptions of clinical conditions derived from patient signs, symptoms and history that identify patients who are likely to benefit from a particular radiographic examination. It makes possible making individual decisions based on history, clinical examination and risk factors. The radiographic selection criteria of dentistry have been revised in accordance with recent guidelines and peer-reviewed research in USA and Europe, but the studies of these subjects are not sufficient in our nation. In this review article, the relating factors and update necessity of radiographic selection criteria are discussed.

Tissue optics is a well-established and extensively studied area. In the last decades, Monte Carlo simulation (MCS) has been one of the standard tools for simulation of light propagation in turbid media. The utilization of parallel processing exhibits dramatic increase in the speed of MCS's of photon migration. Some calculations based on MCS can be completed within a few seconds. Since the MCS's have the potential to become a real time calculation method, a dynamic accuracy estimation, which is also known as history by history statistical estimators, is required in the simulation code to automatically terminate the MCS as the results' accuracy achieves a high enough level. In this work, spatial and time-domain GPU-based MCS, adopting the dynamic accuracy estimation, are performed to calculate the light dose/reflectance in homogeneous and heterogeneous tissue media. This dynamic accuracy estimation can effectively derive the statistical error of optical dose/reflectance during the parallel Monte Carlo process.
