Some of Helicoverpa species (Noctuidae: Heliothinae) are among the worst Lepidopteran agricultural pests in the world, such as H. armigera, H. assulta, H. zea, and H. punctigera. Despite different distribution areas, these species possibly migrate long distances both with and without human transportation, mixing insecticide resistance alleles along the way. As these species are morphologically similar at the larval stage, diagnostic methods have been developed and utilized for their identification. Here, we developed a loop-mediated isothermal amplification (LAMP) assay for rapid and effective species diagnosis, along with PCR, to identify Korean field-collected or overseas samples. Species-specific primers were designed by aligning and comparing the mitochondrial genomes of related species, including four species. There are differences depending on the species and the optimal temperature and reaction time of the LAMP assay, depending on the set of four essential primers. For instance, H. armigera sensitivity is good enough to allow visual discrimination when reacted at 61°C for 30 minutes. This simple and accurate LAMP assay can be used for intensive field monitoring and integrated management of these species.

The Korean government has introduced Official Development Assistance (ODA) Partnership Programs as part of efforts to increase the efficiency of ODA programs while addressing segmentations between grants and concessional ODA programs and projects. This research has significance in the development cooperation policy in Korea, given that the research addresses the confusion related to concepts and challenges regarding ODA Partnership Program, and it also provides policy recommendations to address such challenges. The research on the “Planning of ODA Partnership Program in STI” is conducted with two purposes: the first is to increase the effectiveness of Korea’s ODA programs and to revitalize integrated ODA programs, by analyzing the status and the challenges about current ODA integration policies and programs of the government. The second is to proactively respond to the demands of the Korean government in development cooperation policy and programs by providing planning cases of ODA partnership program in STI. The research consists of two parts: in the first part, the main challenges in ODA integrated policies and programs are identified through conducting in-depth interviews with practical experts from public agencies and universities in the development cooperation community. The research team also conducted a survey to further clarify the issues and to develop policy recommendations to address such challenges. Survey questions are elaborated on the basis of results of the in-depth interviews, and the survey was targeted the experts from implementing agencies of ODA projects and government officials from ODA related ministries. Based on the interview and survey results, policy recommendations for integrated ODA policy and programs are suggested. The second part is how to plan ODA Partnership Program in STI, which can be used by relevant ministries and implementing agencies of ODA projects. The research team developed a guideline for the planning of ODA Partnership Program in STI, which includes process and methodology for the program planning. Based on the guideline, pilot cases of ODA Partnership Programs in STI are developed targeting six countries such as Laos, Sri Lanka, Azerbaijan, Indonesia, Cambodia and Tunisia. The research emphasizes that partnership in STI ODA programs is one of the key policy directions in the development cooperation for the successful transition to the problem-solving ODA programs. With several findings and implications from reviewing challenges and limitations of the current policies regarding ODA Partnership Programs, the research provides policy recommendations about how to implement ODA Partnership Programs in an effective manner. The research also provides useful results for the practitioners of aid projects. The guideline in the research provides the procedures for planning an ODA Partnership Program from the perspective of practitioners. Another contribution of the research also can be found in the problem-solving oriented planning with a top-down approach and the systematic planning procedures for an ODA Partnership Program. The usefulness of the research can be found that pilot cases of ODA Partnership Programs are developed by applying the methodology for ODA Partnership Programs in STI. It is expected that the pilot programs are good references for the government and practitioners in the development and implementation of their future ODA Partnership Programs in STI.

프리캐스트 콘크리트 블록과 강재 리브로 구성된 신형식 아치 교량은 프리캐스트 블록 연결부의 힌지 거동으로 연결부의 응력 및 거동특성이 교량의 안전성에 영향을 줄 수 있다. 따라서 신형식 아치교량의 주요 부재인 프리캐스트 패널의 연결부 거동을 평가하기 위하여 제안된 아치 교량의 3차원 비선형 구조해석을 실시하였다. 제안된 프리캐스트 패널 블록 아치 교량의 구조해석 결과, 아치 교량 프리캐스트 연결부는 아치 교량의 시공단계에 따라 수평 변위 및 수직 변위가 발생하고 연결부의 회전변형을 통하여 제안된 아치 교량이 구조적으로 안정적으로 거동하고 있음을 확인하였다.

Non-linear vibrationof disc brake system, such as judder, squeal, and so on, generated from a disc brake system results in its resonance and the irregular wear of both brake disc and pad. Although the standard methods to verify the non-linear vibration of brake system including a judder are developed, it is complicate to estimate or interpretate the transient vibration generated in low and high frequency level. The accurate brake system modeling and simulation of various input conditions in the time domain should be conducted for analyzing the non-linear transient vibration. In this paper, the accurate model of brake system is used in ADAMS, and its simulation is performed for the various inputs, the parameter study of design factors, as well as each brake components modeling method. Consequently, the accurate brake system model has been developed to evaluate the dynamic performance and vibration of disc brake system.
대학생의 부모자녀관계에 대한 인식이 주관적 안녕감과 심리적 안녕감에 미치는 영향

본 연구에서는 대학생이 인식하고 있는 부모자녀관계가 이들의 주관적 안녕감과 심리적 안녕감에 미치는 영향을 알아보았다. 강원도에 위치한 H대학의 학부 5개 학과의 1∼3학년에 재학하고 있는 대학생 337명을 대상으로 한국적 부모자녀관계인 부자유친성정, 주관적 안녕감, 그리고 심리적 안녕감을 묻는 질문지를 사용하여 조사한 후 평균과 표준편차를 구하고, 상관관계분석과 회귀분석을 통해 밝혀낸 연구의 결과는 다음과 같다. 첫째, 부모자녀관계에 대한 대학생의 인식과 주관적 안녕감 간에는 긍정적인 상관관계가 있는 것으로 나타나 대학생들이 부모와의 일체감과 부모의 헌신성을 높은 수준으로 인식하고 있을수록 대학생들의 주관적 안녕감의 수준도 높아지는 것으로 나타났다. 단계적 중다회귀분석 결과 어머니와의 일체감과 헌신성에 대한 인식, 그리고 아버지와의 일체감과 헌신성에 대한 인식은 모두 대학생들의 주관적 안녕감에 많은 영향을 미치고 있었고 특히 어머니와의 일체감과 헌신성에 대한 인식이 더 많은 영향력을 미치는 것으로 밝혀졌다. 둘째, 부모자녀관계에 대한 대학생의 인식과 심리적 안녕감 간에는 긍정적인 상관관계가 있는 것으로 나타나 대학생들이 부모와의 일체감과 부모의 헌신성을 높은 수준으로 인식하고 있을수록 대학생들의 심리적 안녕감의 수준도 높아지는 것으로 나타났다. 단계적 중다회귀분석 결과 아버지와의 일체감과 헌신성, 그리고 어머니와의 일체감과 헌신성이 대학생들의 심리적 안녕감에 많은 영향을 미치고 있었고 특히 아버지와의 일체감과 헌신성에 대한 인식이 더 많은 영향력을 미치는 것으로 밝혀졌다. This study investigated the effects of college students` recognition with their parents` sense of unity and about their parents` devotion to them on their subjective happiness and psychological well-being. The participants in this study included 337 college students who have various majors in a college in Chunchun, Gangwon-Do, Korea. These college students participated in a survey on their perception of their recognition with their parents` sense of unity and about their parents` devotion to them, subjective happiness, and psychological well-being. The results of this study are as follows. First, the correlation analysis revealed that college students` recognition with their parents` sense of unity and about their parents` devotion to them and their subjective happiness were highly correlated. Stepwise regression analysis showed that college students` recognition with their mothers` sense of unity and about their mothers` devotion to them, and their fathers` sense of unity and about their fathers` devotion to them influenced their subjective happiness.
