국립공원은 주로 산악 지형 내 조성되어 있으므로 산사태에 의한 피해 가능성을 항상 내포하고 있다. 본 연구는 산사태 연구의 일환으로 국립공원 탐방로 내 위험 급경사지를 체계적으로 유지관리하기 위한 방안을 마련하는데 목적이 있다. 국립공원에 특화된 자체 체크리스트를 제작하였으며, 전국 19개 국립공원 183개소 급경사지에 대한 실태조사가 이루어졌다. 실태조사의 최종 목적은 위험 급경사지에 대한 안정화 대책을 마련하는 것으로 현장조사와 안정해석의 과정을 거친다. 일부 급경사지에서는 위험성 판단을 위해 지상라이다 등 특수 장비를 이용한 조사를 시도하였다. 중장기 정비계획을 위한 투자우선순위 공식을 개발하였으며, 현장자료를 이용한 순위 및 위험등급을 산출하였다. 최종적으로 위험 급경사지의 향후 체계적인 관리를 위해 “국립공원 급경사지 유지관리시스템”을 개발하였으며, 모든 현장자료들은 시스템 내 DB화 되었다. National parks, which are located mainly in mountainous areas, are always at risk of damage by landslides. The goal of this study is to establish a method for systematically maintaining hazardous steep slopes along trails in national parks. We produced a checklist suitable for each of the 19 national parks nationwide and investigated 183 slopes. The aim of these investigations is to recommend appropriate slope-stability countermeasures, including field investigations and stability analysis. We made preliminary investigations at specific sites, evaluating the slope hazard using specialized equipment such as terrestrial LiDAR. An investment priority formula was developed, and ranking and hazardous grades were calculated as part of a long-term maintenance plan. Finally, to systematically manage dangerous slopes and to house all the field data within one system, we developed the “Slope Maintenance System in National Parks” based on web server that can show various information for slopes.

Background: The use of neurolytic agents to control neuropathic pain has been described from the last century Phenol and ethyl alcohol have been widely used as neurolytic agents, however, their neurolytic effect is variable in efficacy and duration of action, and infrequently accompanied with grave complications. It has been found that 5% lidocaine causes irreversible conduction blockade in animal studies. The goal of this study was to evaluate the neurolytic effect of 5%o lidocaine on various neuropathic pain syndromes for prolonged analgesia. Methods: Twenty-five patients with a diagnosis of neuropathic pain including trigeminal neuralgia (n = 7), postherpetic neuralgia (n = 10), and postsurgical neuralgia (n = 8) were selected after failure of routine therapeutic regimens. After performing a diagnostic nerve block with 1% lidocaine and 5% lidocaine was injected. The patients were followed for 6 months. Visual analog scale (VAS) scores and side effects were recorded for each patients. Results: A significant decrease in pain scores after neurolytic blockade with 5% lidocaine was seen in all of three pain groups. All the patients reported immediate and prolonged pain relief lasting from 4 weeks to 6 months. None of patients exhibited any appreciable side effects or complications. Conclusions: We suggest that 5% lidocaine may be used safely and effectively for the purpose of prolonged analgesia in selected patients with intractable neuropathic pain syndromes.

Objectives : The purpose of this study was to evaluate whether herbal medication may injure the liver function and kidney function. We clinically studied the changes of biochemistry and complete blood cell count in patients who were hospitalized in Korean hospital. Methods : The subjects were 160 patients admitted in Kangnam Korean hospital, Kyung Hee, whose mean duration of medication was 70 days(min 30, max 252). All patients had been checked biochemistry and complete blood cell count for 30 days since their hospitalization. Results : Aspartate aminotransferase(AST), alanine aminotransferase(ALT), alkaline phosphatase(ALP), blood urea nitrogen(BUN) and Creatinine(Cr) decreased significantly on discharge, compared with the values of admissoin(P<0.05). Total protein significantly elevated on dischrge compared with the values of admisson(P<0.05). Conclusions : This study suggests that even though there are few toxic herbal medicines, in general, herbal medications which are prescribed by oriental medicine doctors should be carefully administered not to hurt liver and kidney function.

Objectives : Metabolic syndrome (MetS) is associated with increasing risk of cardiovascular morbidity and mortality but the risk of stroke associated with the MetS is less well established. The objective of this study was to evaluate the prevalence of MetS in stroke patients. Methods : We analyzed the data of 806 patients with acute ischemic stroke from Hanbang Stroke Registry supported by the Ministry of Science and Technology of Korea. Subjects' enrollment was done in the oriental medical hospitals of 4 universities located in the metropolitan region from April 2007 to August 2008. We analyzed all registered data and evaluated the prevalence of MetS and specific components of MetS. Results : The prevalence of MetS in stroke patients according to American Heart Association/National Heart Lung and Blood Institute (AHA/NHLBI) criteria was 59.6%. The prevalence according to the International Diabetes Federation (IDF) criteria was 41.6%. The prevalence of female patients was higher than that of male patients (71.8% vs 51% by AHA/NHLBI criteria; 61.7% vs 27.7% by IDF criteria). The prevalence of central obesity, low HDL cholesterol and hypertension was higher in female patients. There was no significant relationship between MetS and stroke subtype. Conclusions : This work gives us the basic data on the association between MetS and risk of stroke. There should be the prospective cohort studies to evaluate MetS and the risk of stroke.

The policy change in the Data 3 Act is one of the issues that should be noted at a time when non-face-to-face business strategies become important after COVID-19. The Data 3 Act was implemented in South Korea on August 5, 2020, calling ‘Big Data 3 Act’ and ‘Data Economy 3 Act,’ and so personal information that was not able to identify a particular individual could be utilized without the consent of the individual. With the implementation of the Data 3 Act, it is possible to establish a fair economic ecosystem by ensuring fair access to data and various uses. In this paper, the law on the protection of personal information, which is the core of the Data 3 Act, was compared around Korea, the European Union and the United States, and the implications were derived through network analysis of keywords.

It is widely known that compare to many other countries, the U.S.A. has a strong framework for efficient implementation of mitigation policy to protect wetlands. As indicated in many strong mitigation initiatives, mitigation policy primary requires avoidance rule for wetland damage and if a developer inevitability damages wetlands, the development should be minimize, and as a last resort, the policy impose legal duty that a developer should compensate wetland corresponding to the damaged wetlands. However, the legal system fur Korea's mitigation system does not provide any legal duty for the compensatory mitigation, although the possibility of creation of tidal flat is casually expressed in several Korean legal systems. Therefore, without any strong and enforceable legal system, Korean mitigation system cannot efficiently protect Korea's vast and productive wetlands. To introduce mitigation policy similar to the U.S.A. in Korea, we suggest that there (a) should be a strongly policy which regulate legal duty for the compensatory mitigation, (b) should be an improve management system for actively corresponding to special knowledge relating to environment, and lastly, (c) should be a system which consider a class action introduced in environmental regime for a long term protection of tidal wetlands for future generation.

본 논문에서는 제한된 자원을 가지는 포터블 임베디드 시스템을 위하여, 작은 메모리 사용으로 효율적으로 영상 부호화가 가능한 웨이블릿 영상 부호화기를 제안하였다. 제안된 방법은 부호화 과정시 요구되는 메모리 사용량을 줄이기 위해 웨이블릿 계수들의 비트 레벨 정보를 가지는 2차원 중요 계수 배열을 사용한다. 제안된 방법은 중요 계수에 대한 부호화 과정과 계수들의 비트 레벨 정보의 부호화 과정을 한 번에 수행할 수 있다. 실험 결과 기존의 부호화 방법보다 화질 면에서 비슷하거나 우수한 성능을 보였으며, 2차원 중요 계수 배열을 이용한 최소의 메모리 사용으로 다양한 비트율에서 영상의 일그러짐 없이 안정적으로 동작함을 확인하였다. In order to provide an efficient way to processing with limited resources, we propose a wavelet coder that operates with little memory usage on the portable embedded system. In order to reduce redundancy in coding process caused by repetitive scanning of wavelet coefficients, the proposed coder uses a 2D significance coefficient array (SCA) which records the bit-level information of wavelet coefficients. The 2D SCA improves memory usage and processing speed required for image coding because it can perform significance check and bit coding of coefficients simultaneously.
