유기 포도재배가 늘어남에 따라 이마점애매미충(Arboridia maculifrons), 이슬애매미충(A. maculifrons), 검은볼애매미충(A. nigrigena)의 발생이 늘어나고, 농가에서 방제의 어려움을 격고 있다. 애매미충류는 포도잎을 가해하는 노린재목 흡즙성 해충으로 약충과 성충 모두 엽록소를 파괴하기 때문에 광합성효율을 떨어뜨리고, 당·산도 함량 및 착색 등에 영향을 미치는 대표적 미소해충 중의 하나이다. 애매미충류의 친환경적인 방제를 위해 완전 비가림하우스에서 접착트랩 색에 대한 유인효과를 검정하였다. 검정결과 yellow>blue,purple,white>red 순으로 유인반응을 보였다 실내에서 모니터링 상자를 이용한 LED(Light emitting diode) 반응은 white> green>blue>yellow>red 순으로 유인 반응을 보였으며, 포장시험에서도 white의 효과가 인정되어 일몰후 1시간, 일몰후 2시간, 19~21시로 나누어 야간 시간대별 LED 유인효과를 분석해 본 결과 야간온도가 25℃이상에서 유인효과가 인정되었으며, 20℃이하에서는 유인효과가 없었다. 이는 미소해충이 운동을 위해 필요한 에너지가 기온과 관련이 있기 때문으로 생각된다.

The objective of this study is to examine the potential of cost reduction and factors affecting production cost of Korean farmers. First, the study estimates technical efficiency, allocation efficiency, and cost efficiency of Korean farmers using DEA. Then, Tobit regressions are conducted to identify factors affecting each of the three efficiency scores. The study uses the Farm Household Economy Survey data from the Korean National Bureau of Statistics for the period from 2008 to 2012. Results from DEA show that overall, technical and cost efficiency scores are low, which suggests a great potential of cost reduction for Korean farmers. The results also show relatively large differences in efficiency scores across provinces. Tobit results suggest that farm size, number of family members, operation costs, and invested capital amount are major factors affecting farm efficiencies.

Many pronuclear stage eggs were used to generate transgenic mice (Tg) by microinjection. In this study, we used in vitro fertilized mouse eggs, followed by ultrarapid freezing to establish a simple procedure for production of Tg mice. We produced in vitro fertilized mouse eggs and cryopreserved them by ultrarapid freezing method. A total of 139 cryopreserved-thawed pronuclear eggs, of which 101 (72.6%) were survived following microinjection of chicken b-actin promoter-driven firefly improved luciferase cDNA (β-act/luc+) and were transferred into 5 recipients. All recipients became pregnant and gave birth to a total of 15 (14.8%) pups. As a control, same DNA construction (β- act/luc+) was also injected into 450 in vitro fertilized eggs, of which 338 (75.1%) were survived and then were transferred into 14 recipients. Eleven (78%) mice became pregnant and littered a total of 54 (19.1%) pups. Southern blotting analysis of Tg mice indicated that one (1/15, 6.6%) and three (3/54, 5.5%) transgenic mice were production from cryopreserved and in vitro fertilized eggs, respectively. All Tg mice produced from both eggs showed the expression of improved luciferase gene. These results indicated that efficiency of produced of Tg mice from cryopreserved eggs was comparable to that from in vitro fertilized eggs. Furthermore, it is suggested that microinjection of transgene into in vitro fertilized eggs cryopreserved by ultrarapid freezing is an easy and conveniently method for production of Tg mice.

The live fire test has been playing a critical role in evaluating the goals-to-meet of the weapon systems which utilize the power of explosives. As such, the successful development of the test systems therein is quite important. The test systems development covers that of ranges and facilities including system-level key components such as mission control, instrumentation or observation, safety control, electric power, launch pad, and so on. In addition, proper operational guidelines are needed with well-trained test and operation personnel. The emerging weapon systems to be deployed in future battle field would thus have to be more precise and dynamic, smarter, thereby requiring more elaboration. Furthermore, the safety consideration is becoming more serious due to the ever-increasing power of explosives. In such a situation, development of live fire test systems seems to be challenging. The objective of the paper is on how to incorporate the safety and other requirements in the development. To achieve the goal, an architectural approach is adopted by utilizing both the system components relationship and safety requirement when advanced instrumentation technology needs to be developed and deteriorated components of the range are replaced. As an evaluation method, it is studied how the level of maturity of the test systems development can be assessed particularly with the safety requirement considered. Based on the concepts of both systems engineering and SoS (System-of-Systems) engineering process, an enhanced model for the system readiness level is proposed by incorporating safety. The maturity model proposed would be helpful in assessing the maturity of safety-critical systems development whereas the costing model would provide a guide on how the reasonable test resource allocation plan can be made, which is based on the live fire test scenario of future complex weapon systems such as SoS.

이 연구는 2012년 2월6일 정부가 발표한 학교폭력 근절 종합대책 의 내용을 검토해 보고 학교폭력 예방을 위한 학교 차원의 회복적 사법의 적용과 한국사회 학교폭력의 실태와 효율적 대처방안으로 학교 구성원을 포함한 사회적 공감대의 형성, 학교폭력 근절 종합대책의 실효적 보완을 통한 지속적인 실천, 보다 학교폭력해소를 위한 근본대책을 제시함을 목 적으로 한다. 학교폭력은 세계 각국의 공통적인 현상이라고 할 수 있으 며, 우리나라도 예외는 아니어서 학교폭력에 대한 예방책을 제시 및 시 행하고 있으나 근절에는 미치지 못하고 있는 실정이다. 오히려 학교폭력 은 점차 악화되고 있기까지 하다. 최근 학교폭력의 특징은 흉포화, 저연 령화, 강력화되어 그 심각성은 도를 넘고 있다. 특히 대구 중학생 자살사 건, 경산 고등학생 아파트 투신 자살사건, 대전 여고생 자살사건, 김해 여고생 폭행치사 사건 등의 일련의 자살사건의 원인에 학교폭력이 작용 했다는 것이 알려지면서 심각한 사회문제화 된 학교폭력-청소년비행에 적절한 대응이 이루어지지 못하고 있다는 자성의 목소리가 커지면서 이 에 대한 원인 규명에 대한 노력이 다각도로 이루어지고 있다. 이에 정부 는 학교폭력 피해학생을 실질적으로 보호하며 가해학생을 엄하게 처벌한 다는 대책을 발표했다. 현행 학교폭력 근절대책에서는 피해학생과 가해 학생을 분리시키고 가해학생에게는 출석정지, 강제 전학, 퇴학과 생활기 록부 기재 등이 추가되는 등 처벌을 강화시키고 있는 추세이다. 반면 학 교폭력은 예전과는 또 다른 양상으로 발전·진화하고 있다. 소수 특정학 생에서 일반학생까지 확대되고 있으며 신체적 폭력 외에도 정서적 폭력, 언어폭력, 사이버 폭력, 성추행 등으로 다양해지며 가해자와 피해자의 위 치가 쉽게 전환된다는 점이다. 따라서 본 연구에서는 이와 같이 나날이 진화·발전하는 학교폭력의 사전 예방 및 대처의 한 방법에 주목하여 학생, 가족, 학교 및 지역사회 의 다차원적 개입의 필요성과 피해회복, 피해자-가해자의 조정·화해 및 공동체 강화를 강조하는 회복적 사법이 학교차원에서 실천 적용될 필요 성을 제시하였다.

온실의 냉방부하 산정방법 개발을 위하여 열수지 방법에 기초한 냉방부하 산정식을 구성하고, 포그냉방 온실 에서 냉방부하를 실측하여 검증하였다. 포그냉방 온실의 냉각열량은 포그분사에 의한 증발수량에 물의 증발잠열을 곱하여 구할 수 있다. 여기서, 증발수량은 포그 분사량에 증발효율을 곱하면 구할 수 있으며, 즉 분무수량을 계측하고 포그시스템의 증발효율을 알면 온실의 냉방부하를 실측할 수 있다. 따라서 온실의 냉방부하 실측을 위하여 실험온실에서 포그시스템의 증발효율을 실험하고, 실험온실의 열환경 계측과 더불어 포그 분사량을 계측하여 냉방부하 산정방법을 검토하였다. 먼저 냉방부하 산정식의 환기전열량을 검토하기 위하여 냉방을 실시하지 않은 상태에서 환기량 실측 실험을 통해 비교한 결과 열수지식을 이용한 환기전열량 예측은 비교적 양호한 결과를 보이는 것으로 나타났다. 이류체 포그시스템의 증 발효율은 0.3~0.94의 범위를 보였으며 평균 0.67로 나타 났고, 환기율이 증가함에 따라 커지는 것으로 나타났다. 포그냉방을 실시하면서 온실의 환경을 계측하여 열수지 식으로 냉방부하를 계산하고, 분무량 실측치로부터 증발 냉각열량을 구하여 비교한 결과 냉방부하 계산치와 실측치는 대체로 유사한 경향을 보이는 것으로 나타났다. 냉방부하가 낮은 경우에는 실측치에 비하여 약간 크게 예측되었고, 냉방부하가 높은 경우에는 실측치보다 작게 예측되었다. 온실의 냉방시스템 설계 시에는 최대냉방부하를 이용하여 냉방설비의 용량을 결정하게 된다. 따라서 냉방부하가 큰 쪽에서 실측치보다 작게 예측되는 부분은 검토가 필요하지만 설비용량 산정시의 안전계수를 고려하면 본 연구에서 제시한 냉방부하 산정방법은 온실의 환경설계에 적용할 수 있는 것으로 판단된다.

The need for contents that uses motion capture has increased recently. Motion capture realizes the various motions as the data collected through the marker reacts to the characters after being converted to digital data. However, if generalizing the various methods that have been conducted so far, it is somewhat unreasonable to complete animation only with motion capture. The existing motion capture field have been carried out based on the equipment operation and technology development and the advanced research of motion capture-producing pipeline for the production of animation is insufficient as well. This study suggests the realistic animation-producing pipeline by modeling, character setup, calibration, motion capture, data modification and integration of animation for each phase based on such methods.

Recently, management based on statistical data has become a big issue and the importance of the statistics has been emphasized for the management innovation in the defense area. However, the Military Management based on the statistics is hard to expect because of the shortage of the statistics in the military. There are many military information systems having great many data created in real time. Since the infrastructure for gathering data form the many systems and making statistics by using gathered data is not equipped, the usage of the statistics is poor in the military. The Analytical Defense Statistics System is designed to improve effectively the defense management in this study. The new system having the sub-systems of Data Management, Analysis and Service can gather the operational data from interlocked other Defense Operational Systems and produce Defense Statistics by using the gathered data beside providing statistics services. Additionally, the special function for the user oriented statistics production is added to make new statistics by handling many statistics and data. The Data Warehouse is considered to manage the data and Online Analytical Processing tool is used to enhance the efficiency of the data handling. The main functions of the R, which is a well-known analysis program, are considered for the statistical analysis. The Quality Management Technique is applied to find the fault from the data of the regular and irregular type. The new Statistics System will be the essence of the new technology like as Data Warehouse, Business Intelligence, Data Standardization and Statistics Analysis and will be helpful to improve the efficiency of the Military Management.

nfrastructure such as tracks, catenary, rolling stock and signaling systems, and close interface with the human factors of train drivers, shunting staff and maintenance staff are required for train operations. Safety management is the most essential part for the functioning of a train. In line with the safety management, each rail operator has a safety guidance system and the Ministry of Land, Infrastructure and Transport operates Railway Safety Inspector system. Safety Inspector System is to train employees working in the field to be aware of rules and regulations, and to improve identified risk factors. Hence, it is necessary to establish systematic training and inspection methods for safety guidance staff and make clear the roles and responsibilities of safety inspectors according to the Occupational Safety and Health Act, and safety instructors for several inspections according to the Railroad Safety Act.

An effective method for produce munitions effectiveness data is to calculate weapon effectiveness indices in the US military’s Joint Munitions Effectiveness Manuals (JMEM) and take advantage of the damage evaluation model (GFSM) and weapon Effectiveness Evaluation Model (Matrix Evaluator). However, a study about the Range Safety that can be applied in the live firing exercises is very insufficient in the case of ROK military. The Range Safety program is an element of the US Army Safety Program, and is the program responsible for developing policies and guidance to ensure the safe operation of live-fire ranges. The methodology of Weapon Danger Zone (WDZ) program is based on a combination of weapon modeling/simulation data and actual impact data. Also, each WDZ incorporates a probability distribution function which provides the information necessary to perform a quantitative risk assessment to evaluate the relative risk of an identified profile. A study of method to establish for K-Range Safety data is to develop manuals (pamphlet) will be a standard to ensure the effective and safe fire training at the ROK military education and training and environmental conditions. For example, WDZs are generated with the WDZ tool as part of the RMTK (Range Managers Tool Kit) package. The WDZ tool is a Geographic Information System-based application that is available to operational planners and range safety manager of Army and Marine Corps in both desktop and web-based versions. K-Range Safety Program based on US data is reflected in the Korean terrain by operating environments and training doctrine etc, and the range safety data are made. Thus, verification process on modified variables data is required. K-Range Safety rather than being produced by a single program, is an package safety activities and measures through weapon danger zone tool, SRP (The Sustainable Range Program), manuals, doctrine, terrain, climate, military defence M&S, weapon system development/operational test evaluation and analysis to continuously improving range safety zone. Distribution of this K-range safety pamphlet is available to Army users in electronic media only and is intended for the standing army and army reserve. Also publication and distribution to authorized users for marine corps commands are indicated in the table of allowances for publications. Therefore, this study proposes an efficient K-Range Safety Manual producing to calculate the danger zones that can be applied to the ROK military’s live fire training by introducing of US Army weapons danger zone program and Range Safety Manual

연구에서는 연색 지수가 90이상의 초고연색성 백색 발광다이오드를 구현하기 위해서, 황색형광체로서 Y3Al5O12:Ce3+, 녹색형광체로서 Lu3Al5O12:Ce3+ 그리고 적색형광체로서 InP/ZnS 양자점을 적용한 형광체 변환방식의 백색 발광다이오드의 새로운 조합을 제안하였다. 또한 발광효율을 향상하기 위해서 청색 칩 위에 이증 구조의 형광 체 도포방식을 적용하였다. 적색 InP/ZnS 양자점을 적용하여 만들어진 백색 발광다이오드는 동작전류 60mA, 상관 색온도 5200K 조건하에서 발광효율이 123 lm/W 이상이며, 90 이상의 초고연색성을 나타내었다. 상업적으로 적용된 초고연색성 백색 발광다이오드 제품과 비교해 보면, 적색 InP/ZnS 양자점을 적용한 형광체 변환 방식에 의한 백색 발광다이오드 연구 결과는 고체조명 응용에 적용될 수 있을 것으로 예상된다.

In this paper, scale efficiencies and relative efficiencies of R&D projects in Industrial Technology Program, sponsored by Ministry of Trade, Industry and Energy, Korea, are calculated and compared. For the process, various DEA (Data Envelopment Analysis) models are adopted as major techniques. For DEA, two stage input oriented models are utilized for calculating the efficiencies. Next, the calculated efficiencies are grouped according to their subprograms (Industrial Material, IT Fusion, Nano Fusion, Energy Resources, and Resources Technology) and recipient types (Public Enterprise, Large Enterprise, Medium Enterprise, Small Enterprise, Lab., Univ., and etc.) respectively. Then various subprograms and recipient types are compared in terms of scale efficiencies (CCR models) and relative efficiencies (BCC models). In addition, the correlation between the 1st stage relative efficiencies and the 2nd stage relative efficiencies is calculated, from which the causal relationship between them can be inferred. Statistical analysis shows that the amount of input, in general, should increase in order to be scale efficient (CCR models) regardless of the subprograms and recipient types, that the 1st and 2nd stage relative efficiencies are different in terms of the programs and recipient types (BCC models), and that there is no significant correlation between the 1st stage relative efficiencies and the 2nd stage relative efficiencies. However, the results should be used only as reference because the goal each and every subprogram has is different and the situation each and every recipient type faces is different. In addition, the causal link between the 1st stage relative efficiencies and the 2nd relative efficiencies is not considered, which, in turn, is the limitation of this paper.

본 연구는 환경오염과 양수분 손실을 주는 비순환식 수경재배에 FDR센서를 이용한 자동관수시스템을 적용할 때 관수효율을 높이기 위한 최적의 최소대기시간을 설정하고자 수행되었다. 실험은 가을과 겨울철에 봄과 여름철에 두 번 수행하였고 가을과 겨울철에는 3분 급액과 최소대기시간을 5분으로 한 3R5F 처리구, 3분 급액과 최소대기시간을 10분으로 한 3R10F 처리구, 5분 급액과 최소대기시간을 15분으로 한 5R15F 처리구를 설정하여 실험하였고 봄과 여름철에는 3분 급액과 최소대기시간을 5분으로 한 3R5F 처리구, 3분 급액과 최소 대기시간을 10분으로 한 3R10F 처리구를 설정하여 실험하였다. 3분 급액은 주당 60mL, 5분 급액은 주당 80mL가 공급되었다. 가을과 겨울철 재배에서 정식 후 62일 까지 주당 급액량은 3R5F (858mL) > 5R15F (409mL) > 3R10F (306mL) 처리 순으로 나타났고 배액률은 3R5F (44%) > 5R15F (23%) > 3R10F (14%) 순으로 나타났다. 정식 후 62일부터 102일 까지는 일일 주당 급액량이 5R15F (888mL)> 3R5F (695mL)> 3R10F (524mL) 순으로 나타났고 이 시기에 배액률은 5R15F에서 가장 높았다. 봄과 여름재배에서는 일일 주 당 급액량과 배액율이 3R5F 처리구에서 3R10F 처리구보다 높았다. 두 재배 모두에서 수분이용효율 (WUE)은 3R10F 처리에서 높았다. 따라서 FDR 센서를 활용한 자동화 관수 시스템에서 관수효율을 높이기 위한 최소대기시간은 10분으로 고찰된다.

The hydro–acoustic technology has been widely used in not only South Korea but also many foreign countries for various scientific purposes. Unfortunately acoustic data especially collected from field surveys may contain noises caused by a variety of sources. Therefore, it is exceedingly important to eliminate noises when acoustic data are analyzed to derive quantitative results. This study introduced two methods for eliminating noises easily and effectively using post–processing software. Used acoustic data were collected on the Jinhae bay and Tongyeong coast of the South Sea in April 2015. The first method, that is the Wang’s method, placed emphasis on ‘erosion filter’ to eliminate only data samples contaminated by noises. The second method (Yamandu’s method) focused on the ‘resample by number of pings’ to remove pings contained noises. To substantiate the effectiveness of two methods, the mean Sv (Volume backscattering strength), mean height and depth of the fish schools detected were compared between before and after using the noise elimination methods. In the Wang’s method the mean Sv was decreased from –52.4 dB to –52.9 dB, and in the Yamandu’s method from –52.6 dB to –53.3 dB, indicating that noises were successfully eliminated. The mean height (1.5 m) and depth (19.0 m) were same between before and after using two methods showing that the shapes of fish schools were not changed.

본 연구에서는 미국 일본 등 해양선진국에서 운영하고 있는 민간해양구조세력의 사례와 국내 의용소방대의 현황을 조사, 비교분석하였다. 이를 통해 한국해양구조협회와 민간해양구조대로 이원화되어 있는 해양구조세력을 일원화하여 통합구조체제를 갖추고, 법제화를 통해 안정적인 육성 지원책을 마련할 필요가 있었다. 효율적인 구조활동을 위해 미국 캐나다처럼 정부기관에서 지휘 통솔권을 갖추도록 법령을 정비하고 교육 훈련을 체계화하며 전문교육기관 위탁교육 등을 통하여 구조역량을 높여야 할 것으로 판단되었다. 민간구조세력의 안정적인 지위를 유지하기 위해 정부지원금 등 재정지원책을 마련하며, 해양구조 업무를 담당하는 일원으로 사명감과 자긍심 고취를 위해 국내 외 연수 등 사기진작책 마련 등 법적, 제도적 개선사항을 도출하여 제시하였다.

This study is to analyze the efficiency of Korean sea food manufacturing using Data Envelopment Analysis. Firstly, based on an output oriented traditional CCR, BCC model, the study estimated the efficiency scores. The average estimates of technical, pure technical, and scale efficiency turned out 0.6517, 0.7184, 0.9074 respectively, which are separated for 50 marine corporations. The 10 DMUs were efficient under CCR model while the 17 DMUs under BCC model. Also, the study suggested that the operating profit of the two output factors should be more increased relatively and averagely from the viewpoint of efficiency improvement. Secondly, super efficiency scores are estimated under super efficiency and SBM model. As a result, it came to be possible to distinguish and rank the efficiency of the efficient DMUs. The highest score was 4.2975 under Super-CCR, was 2.4947 under Super-BCC, was 2.7160 under SBM-Super- CCR, and was 1.5319 under SBM-Super-BCC model. The average estimates of super efficiency were 0.76 and 0.82 under Super-CCR and Super-BCC model respectively, and were 0.61 and 0.67 under SBM-Super- CCR and SBM-Super-BCC model. Finally, the study conducted a rank-sum test, Wilcoxon-Mann-Whitney test, to find a statistical significance of heterogeneity existing in efficiencies among the sample corporations. The result showed that there was a significant difference in average efficiency between Dried, Salted product manufacturing and Frozen product manufacturing under BCC-Super efficiency model at 10% level of significance. Furthermore, TOBIT model was applied to find out the potential factors that might influence the efficiency, Wilcoxonand the results showed debt and sales cost influenced all of the technical, pure technical, and scale efficiency, while net profit influenced only the technical efficiency.

PURPOSES: This study has been conducted to determine a homogeneous segment and integration to improve the efficiency of short-term traffic count. We have also attempted to reduce the traffic monitoring budget. METHODS: Based on the statistical approach, a homogeneous segment in the same road section is determined. Statistical analysis using t-test, mean difference, and correlation coefficient are carried out for 10-year-long (2004-2013) short-term count traffic data and the MAPE of fresh data (2014) are evaluated. The correlation coefficient represents a trend in traffic count, while the mean difference and t-score represent an average traffic count. RESULTS : The statistical analysis suggests that the number of target segments varies with the criteria. The correlation coefficient of more than 30% of the adjacent segment is higher than 0.8. A mean difference of 36.2% and t-score of 19.5% for adjacent segments are below 20% and 2.8, respectively. According to the effectiveness analysis, the integration criteria of the mean difference have a higher effect as compared to the t-score criteria. Thus, the mean difference represents a traffic volume similarity. CONCLUSIONS : The integration of 47 road segments from 882 adjacent road segments indicate 8.87% of MAPE, which is within an acceptable range. It can reduce the traffic monitoring budget and increase the count to improve an accuracy of traffic volume estimation.

In this paper we describe differential circuit of charge pump for voltage management systems, their evolution and improvement in design. The systems are powered by solar cells and generate different voltage levels which are suitable for systems on-chip integrated regulator applications. The voltage regulator outputs voltage from low power digital circuit, -2V for memory, and from 2V to 12V for input and output components. The circuits were simulated using LT SPICE software.

Depending on the living styles, the types of energy consumed by households have changed, and the consumption has increased rapidly. Consequently, those have led to environmental issues, such as exhaustion of energy and the climate changes. As one of solutions to such issues, energy efficiency can be approached. Therefore, in this study, the gas water heater(115S type Rheem products) that made in Germany and obtain hot water using gas as a heat source is selected. a 1.0㎥ water tank with a 6kW electronic heater is installed and a water temperature and pressure is maintain constantly also thermometer is injected.
