Demand for manpower of conducting pharmaco-economic evaluation was investigated. The priority order of conducting economic evaluation on the already listed drugs was set by the budget impact for health insurance by the therapeutic groups. Manpower demand was estimated by the Anatomical, Therapeutical, Chemical (ATC) code. The total number of economic evaluation on the already listed drugs is estimated to be 346 cases. Based on these numbers, at least 53${\sim}$102 of full-time-equivalent (FTE) manpower is needed for conducting economic evaluation per year in the following 5 years.

본 논문에서는 클러스터 단위로 센서 노드의 키와 그룹키를 생성한 후 분배하는 KGDC(Key Generation and Distribution based on Cluster) 모듈과 이 키를 이용하여 시빌 공격과 웜홀 공격을 탐지할 수 있는 SWAD(Sybil & Wormhole Attack Detection) 모듈로 구성되는 SWAD-KNH(Sybil & Wormhole Attack Detection using Key, Neighbor list and Hop count) 기법을 제안한다. KGDC 모듈은 ECDH 알고리즘, 해시함수, 키 체인 기법을 이용하여 그룹키와 센서 노드의 키들을 생성하고 안전하게 배포한다. SWAD 모듈은 2단계 키 확인절차를 수행함으로써 시빌 공격 탐지를 강화시키고, 근원지와 목적지 노드의 공동이웃노드들의 수와 홉 카운트를 이용하여 웜홀 공격을 탐지한다. 그 결과 SWAD-KNH 기법은 시빌 공격 탐지율은 91.2%, 평균 FPR(False Positive Rate)은 3.82%이고, 그리고 웜홀 공격 탐지율은 90%, 평균 FPR(False Positive Rate)은 4.64%으로 평가되므로 시빌과 웜홀 공격 탐지율 및 시빌과 웜홀 공격 탐지의 신뢰성을 향상시켰다.

미국선녀벌레에 방제효과가 높은 3종 (데리스, 시트로넬라, 계피)의 식물추출물과 보조제 (잔탄검과 실리콘 계열 화합물)를 함유하는 조성물을 개발하였다. 이 조성물은 인삼 재배지에서 미국선녀벌레 방제효과가 90% 이상으로 높았다. 또한 다른 흡즙성 해충에도 살충률이 높아 PLS (positive list system) 전면 시행에 따른 대응방안으로 활용이 가능할 것으로 생각된다.

Because HTTP-related ports are allowed through firewalls, they are an obvious point for launching cyber attacks. In particular, malware uses HTTP protocols to communicate with their master servers. We call this an HTTP-based command and control (C&C) server. Most previous studies concentrated on the behavioral pattern of C&Cs. However, these approaches need a well-defined white list to reduce the false positive rate because there are many benign applications, such as automatic update checks and web refreshes, that have a periodic access pattern. In this paper, we focus on finding new discriminative features of HTTP-based C&Cs by analyzing HTTP activity sets. First, a C&C shows a few connections at a time (low density). Second, the content of a request or a response is changed frequently among consecutive C&Cs (high content variability). Based on these two features, we propose a novel C&C analysis mechanism that detects the HTTP-based C&C. The HAS-Analyzer can classify the HTTP-based C&C with an accuracy of more than 96% and a false positive rate of 1.3% without using any white list.

인류의 문화에 가상과 현실의 융합과 게이미피케이션 혁명이 시작되고 있다. 4차 산업혁명시대를 맞이하며, 융합의 핵심 콘텐츠인 게임이 인류의 놀이 상품으로서 큰 발전이 예상된다. 지금은 다양한 게임 IP가 필요한 만큼, 게임시나리오 창작에 쉽게 접근할 수 있는 방법론이 필요한 시점이다. 게임시나리오의 창작은 일반적인 영상 시나리오와 상호작용성에서 매우 큰 차이를 지닌다. 따라서 상호작용적인 지식이 없으면, 게임시나리오 창작에 도전하기가 힘들다. 이 논문에서는 게임시나리오 창작의 진입장벽을 낮추기 위해 '게임시나리오 창작 리스트'를 만들었다. 이 논문이 게임 콘텐츠의 발전에 조금이라도 보탬이 되길 기대해 본다.

This study is to find out primary factors through the punch list in the large scale apartment housing complex, to prevent repeatedly occurring defects of construction and to gain quality management. The following are the findings of the research. (1) The positive strengthening of supervision for the workers can contribute to prevent defects of apartment construction and make better quality of the construction. (2) A solution should be made for the poor of surface join and the damage of work element showing a lot in the apart construction, which prevent defects and improve construction quality. (3) Indirect factors such as negligence and carelessness of the management should be improved to advance construction quality, and the caution and control strengthening of the management should be followed. It is revealed that hitch, omission, and heedlessness come from the defects, and the shortage of skill and checking appear as indirect factors. Therefore, to get quality improvement, the enhancement of the management factors, employment of excellent workers, and enhancement of working attitude and construction management are needed.

'농약 허용물질목록 관리제도(Positive List System, PLS)'는 당해 농산물에 등록된 농약 잔류허용기준이 없으면 일률기준 0.01 mg/kg을 적용하는 제도이다. 본 연구에서는 경기도 내에서 유통되는 열대과일류의 잔류농약 모니터링을 실시하여 PLS의 실효성을 검토하고, 국내 재배 열대과일의 농약 잔류허용기준 설정에 기초자료를 제공하고자 하였다. 경기도 내 유통되는 열대과일류 120건에 대해 다종농약다성분 분석법에 따라 잔류농약 220종을 검사한 결과 바나나, 망고, 키위 3품목 7건에서 6종의 잔류농약이 검출되었다. 바나나에서 azoxystrobin와 chlorpyrifos, 망고에서 chlorfenapyr, 키위에서 chlorothalonil, iprodione, procymidone이 검출되었다. 그 중 국내산 망고에서 chlorfenapyr, 국내산 키위에서 chlorothalonil이 각각 1건씩 검출되었고 PLS 적용 결과 잔류허용기준을 초과하여 부적합 판정 되었다. 따라서 국내에서 재배되는 열대과일류를 대상으로 농약 잔류허용기준을 설정할 필요가 있다.

Objectives: This study was designed to investigate the dose-dependent effects of Gastrodia elata Blume for memory improvement. Methods: This study was a 12-weeks, double blind, and comparative clinical study. Those who were eligible worked with a group of healthy seniors, all 60 years of age or older. 22 subjects were randomized either to Gastrodia elata Blume powder form that was steeped in hot water or placebo. We measured the faculty of memory by using MMSE-K, Digit Span, Letter Fluency Test, Word List Memory Test, and Trail Making Test, and again after 12 weeks. Results: 1) Neither Gastrodia elata Blume groups nor control have a difference in MMSE-K, Digit Span, Letter Fluency Test, and Trail Making Test. 2) Gastrodia elata Blume group showed significant advances in immediate recall 1 and 2 of Word List Memory Test, and 3 g group show better results than the 4 g group. 3) 4 g Gastrodia elata Blume group showed significant advances in the recognition of Word List Memory Test. Conclusions: The results suggest that positive effects on memory improvement due to Gastrodia elata Blume depend on the amount.

In this investigation, the following study was carried out for an experimental proposal of the knit item lists which were not actualized due to lack of studies. First of all, we have put the knit item titles that have been used through the document investigation, into the lists in order to clarify the original item list. Furthermore, we have pointed out the problems and the areas to be developed in the original item lists, and proposed twenty new knit item lists. By defining the design traits of each item, we have established item list which could be classified more systematically. As a result, the knit item titles of twenty newly proposed item titles are knit pull over, knit pull over top, knit top, knit t shirt, knit shirt, knit polo shirt, knit blouse, knit vest, knit hood, knit jumper, knit jacket, knit coat, knit cardigan, knit ensemble, knit cape, knit shawl, knit bikini, knit one-piece, knit pants, and knit skirt. Secondly, in order to investigate the possibility of practical use of twenty knit item lists proposed by this study, we have applied anova with repeated measurement for foreign fashion collection knit item trends of the past 10 years based on the proposed item lists. As a result, four items classified as top, shirt, cardigan, and pants had similar changes in the trend for last 10 years in S/S season while eleven items classified as pull over, pull over top, blouse, vest, jacket, coat, cardigan, ensemble, cape, shawl, and one-piece had similar trend changes for F/W season. The first significance of this study is on the experimental proposal of knit item list which could be used in the actual clothing industry and academic field. Furthermore, by defining the design traits of each knit item, it sublated the confusions brought by vocabularies in design of knit products and distribution in the industry perspective, and it made it possible to categorize the knit items correctly in knit design analysis and knit design education in academic field. The second significance shows that this study brought about positive results in the possibility of industrial academic practical use of proposed list by indicating that most of the knit designs appeared in the foreign collections in the past ten years could be correctly classified through investigational analysis.
