There are increasing number of patients having dental treatment under outpatient general anesthesia. There were researches that studied patients treated under outpatient general anesthesia in Chonbuk National University Dental hospital between 2005~2013. However, there has been an absence of research since 2013. Therefore, the aim of this research is to study cases regarding outpatient general anesthesia visiting Chonbuk National University hospital between 2014~2017 and analyze the trends of these patients. The medical records of 409 cases from January, 2014 to December, 2017 were reviewed. From the patients' charts, data on sex, residence, visiting dates, disability status, and types and number of treatments was collected and investigated. The number of cases has increased from 86 in 2014 to 140 in 2017. Among 409 cases, 275 cases(67.2%) had disabilities, with mental disabilities consisting most of the disabilities. 192 cases were aged under 20 years old mostly with no disabilities, 142 cases were 20~39 years old mostly with mental disabilities, and 75 cases were 40 years old or more mostly with physical disabilities. The conservative treatment was performed most frequently in both disabled and non-disabled patient groups. There was an increasing trend in the number of patients treated under outpatient general anesthesia, and more than half were disabled patients. In order to meet this demand, Chonbuk National University Dental Hospital increased the number of general anesthesia pracrice. To follow this trends, the implementation of safe outpatient general anesthesia system and cooperation among teams is needed to improve the quality of treatments.

Gangneung Danoje does not only have the longest history but also is the largest folk festival in Korea. However, during its long history Gangneung Danoje has not always been the way as it is today. As records reveal, since the Chosun dynasty and through Japanese rule, it has gone through numerous variations and registration processes in order to become a national designated major intangible cultural asset. Especially after it has been appointed as a national major intangible cultural asset Gangneung Danoje has under gone through variety of transformations. First of the few changes is the citizen-lead characteristic. As Gangneung Cultulral Center took charge of Danoje this trait has become prominent. Hereby Chosun dynasty's government lead system has transformed into a civilian lead festival. Second alteration is the enormous scale of expansion and the variations of the characteristic of the festival because of it. Dano event has increased annually from 12 events in 1974 to 58 events by 1999. As the scale of Danoje enlarged the promoters found solutions by providing diversified events in order to satisfy peoples' various aspirations from the festival. However this solution lead to a diversion - from participating festival to a spectating festival. And the last change that occurred is the awareness of the need to develop Danoje into an international festival. This is rather a desire from the government than of the people. In 1994, Korea visiting year as an opportunity this consciousness grew active. For instance, the invitation of mass foreign folk performance in 1999 seems to conform to this policy. The intention to make Gangneung Danoje not only to represent Gangneung but also to represent Korea's folk event can be witnessed. As we enter 21st Century this inclination for international festival has strengthened. Gangneung government has shown enthusiasm to find the future of Danoje by inviting external service corps to assess Danoje. The current inclination appears to be increase its value as an international festival through UNESCO cultural property registration and having this as a foundation make Danoje become an international cultural tourist product. The judgment of this will be made after Gangneung International Folklore Festival 2004.

Purpose: This study empirically examines the effect of Communication Privacy Management(CPM) factors and Privacy Calculus factors to the intention to disclose Personal Health Information(PHI) in the context of healthcare ecosystem. Also, it investigates the moderating effects of CPM factors in the relationship between privacy calculus variables and the intention to disclose PHI. Methods: We conducted scenario-based repeated-measures quasiexperiment and used total 364 samples for analysis. Confirmatory factor analysis and repeated-measure ANOVA were employed using SPSS 24.0. Results: All CPM factors, such as type of information, requesting purpose, and requesting stakeholder, directly influence to the intention to disclose PHI, whereas only the medium trust out of the Privacy Calculus factors has direct influence on the intention to disclose PHI. With regard to the moderating effects, the requesting stakeholder is the most influential and the information type is the least influential construct. Conclusion: The findings suggest that healthcare system should be designed to provide more definite and personalized benefits to customers to enhance social and individual benefits by getting more participation from customers. Also, it is desirable that the requesting stakeholder of PHI would be non-profit organizations such as hospital, government or public agencies to secure more willingness of PHI from people. Furthermore, it is implied that extensive information gathering and utilization, instead of excluding sensitive information or critical patients' records, is recommended which is substantial to invigorate the healthcare industry.

Objectives: Medication-related osteonecrosis of the jaw (MRONJ) is a well-known side effect of certain drugs that are used to influence bone metabolism to treat osteometabolic disease or cancers. The purpose of our study was to investigate how high-concentration and low-concentration bisphosphonate (BP) intake affects the disease severity. Materials and Methods: Data collected from the medical records of 52 patients treated with BPs, antiresorptive, antiangiogenic drugs and diagnosed with MRONJ were included in this study. Age, sex, type of systemic disease, type of drug, duration of drug treatment, jaw area with MRONJ, drug administration protocol, and MRONJ clinical and radiological findings were obtained. Patients were divided into two groups: anti-neoplastic (Group I, n=23) and anti-osteoporotic (Group II, n=29). Statistical evaluations were performed using the IBM SPSS ver. 21.0 program. Results: In both groups, more females had MRONJ. MRONJ was found in the mandibles of 30 patients (Group I, n=14; Group II, n=16). When we classified patients according to the American Association of Oral and Maxillofacial Surgeons staging system, significant differences were seen between groups (${\chi}^2=12.23$, P<0.01). More patients with advanced stage (stage 2-3) MRONJ were found in Group I (60.9%). Conclusion: According to our results, high-concentration BP intake, age and duration of drug intake increased disease severity.

Background: The stem exclusion stage is a stage of forest development that is important for understanding the subsequent understory reinitiation stage and maturation stage during which horizontal heterogeneity is formed. Over the past 11 years (2009-2019), we observed a deciduous broad-leaved forest in the Albongbunji Basin in Ulleungdo, South Korea in its stem exclusion stage, where Fagus engleriana (Engler's beech) is the dominant species, thereby analyzing the changes in the structure (density and size distributions), function (biomass and species richness), and demographics. Results: The mean stem density data presented a bell-shaped curve with initially increasing, peaking, and subsequently decreasing trends in stem density over time, and the mean biomass data showed a sigmoidal pattern indicating that the rate of biomass accumulation slowed over time. Changes in the density and biomass of Fagus engleriana showed a similar trend to the changes in density and biomass at the community level, which is indicative of the strong influence of this species on the changing patterns of forest structure and function. Around 2015, a shift between recruitment and mortality rates was observed. Deterministic processes were the predominant cause of tree mortality in our study; however, soil deposition that began in 2017 in some of the quadrats resulted in an increase in the contribution of stochastic processes (15% in 2019) to tree mortality. The development of horizontal heterogeneity was observed in forest gaps. Conclusions: Our observations showed a dramatic shift between the recruitment and mortality rates in the stem exclusion stage, and that disturbance increases the uncertainty in forest development increases. The minor changes in species composition are likely linked to regional species pool and the limited role of the life-history strategy of species such as shade tolerance and habitat affinity. Our midterm records of ecological succession exhibited detailed demographic dynamics and contributed to the improvement of an ecological perspective in the stem exclusion stage.

By means of installing sloped rolling-type seismic isolators (SRI), the horizontal acceleration transmitted to the to-be-protected object above can be effectively and significantly reduced under external disturbance. To prevent the maximum horizontal displacement response of SRI from reaching a threshold, designing large and conservative damping force for SRI might be required, which will also enlarge the transmitted acceleration response. In a word, when adopting seismic isolation, minimizing acceleration or displacement responses is always a trade-off. Therefore, this paper proposes that by exploiting the possible information provided by an earthquake early warning system, the damping force applied to SRI which can better control both acceleration and displacement responses might be determined in advance and accordingly adjusted in a semi-active control manner. By using a large number of ground motion records with peak ground acceleration not less than 80 gal, the numerical results present that the maximum horizontal displacement response of SRI is highly correlated with and proportional to some important parameters of input excitations, the velocity pulse energy rate and peak velocity in particular. A control law employing the basic form of hyperbolic tangent function and two objective functions are considered in this study for conceptually developing suitable control algorithms. Compared with the numerical results of simply designing a constant, large damping factor to prevent SRI from pounding, adopting the recommended control algorithms can have more than 60% reduction of acceleration responses in average under the excitations. More importantly, it is effective in reducing acceleration responses under approximately 98% of the excitations.

Purposes: The purpose of this study is to analyze the institutional and personal factors that affect the medical utilization of patients transferred to tertiary medical institutions. Methodology: We retrospectively analyzed the 2 weeks electronic medical records of 1,556 patients, who were referred to the tertiary hospital, from June 15 to 26, 2015. The patient's personal characteristics, referral hospital, referral path, medical experiences and expenses were analyzed for 6 months after the patient's first visit. Findings: The largest proportion (848; 54.5%) of referrals was referred from primary clinic but the referrals of the same tertiary hospital level were one in seven (228; 14.7%) of the patients. Most patients (1,401; 90%) were referred from the clinics and hospitals directly and only one in ten (155; 10%) of the patients utilized the medical referral center. Patients who had been referred from tertiary care institutions had significantly higher medical costs than those referred to primary care (7,560,000 vs 2,333,000 won). The institutional factors including the numbers of visits to outpatient clinic, previous history of hospitalization and operation, consultation to other medical departments and hospitalization fee significantly influenced on medical utility pattern. Personal factors including patient's medical diagnosis and department of disease have a highly correlation with patient's referrals. Practical implications: The medical utilization of medical expenses and experiences is influenced by institutional and individual factors, and it is important to establish a referral system considering the institutional factors of the type of referral hospital.

병원에서는 의료 기록저장 시스템 EMR (Electronic Medical Record)을 통하여 개인 정보 및 건강 정보를 저장 및 관리한다. 그러나 병원의 정보 공유를 위한 다양한 서비스를 제공함에 따라 취약점과 위협이 증가하고 있다. 따라서 본 논문에서는 EMR에서 환자 정보의 전송으로 인한 개인 정보 유출을 방지하기 위한 모델을 제안하였다. 환자의 의료 기록이 저장된 병원으로부터 환자 정보를 안전하게 수신 및 전달할 수 있는 권한을 부여하기 위한 방법을 OAuth 권한 위임 토큰을 사용하여 제안하였다. OAuth Token에 의사 정보와 환자가 원하는 기록 열람 제한을 적용하여 전달함으로써, 안전한 정보 전달이 가능하도록 프로토콜을 제안하였다. OAuth Delegation Token은 환자 정보를 열람할 수 있는 권한, 범위, 파기 시점 등을 작성하여 전달 가능하다. 이를 통하여 안전한 환자 정보 전달 및 환자 정보 재사용 금지를 방어할 수 있다. 또한, 불법적인 환자 정보 수집을 방지하고 전달 과정에서 발생할 수 있는 개인 정보의 유출을 방지한다.
