        Helicoverpa assulta (Lepidoptera: Noctuidae) exhibits a specialized herbivorous diet, primarily targeting select Solanaceae plants. Despite its significant economic impact as a pest, causing substantial harm to crops like hot pepper and tobacco, it has received comparatively limited attention in research compared to its generalist counterparts, H. armigera and H. zea.We introduce a chromosome level genome assembly using a Korean H. assulta (Pyeongchang strain, K18). This assembly was achieved through a combined approach utilizing Nanopore long-read sequencing (approximately 78X coverage) and Illumina NovaSeq short-read sequencing (approximately 54X coverage). The total assembled genome spans 424.36 Mb, designated as ASM2961881v1, comprises 62 scaffolds, with 98.7% of the genome contained within 31 scaffolds, confirming the insect's chromosome count (n = 31). The completeness of the assembly is reflected in BUSCO assessment, with values reaching 99.0%, while the repeat content accounts for 33.01%, and 18,593 CDS were annotated. Additionally, 137 genes were identified within 15 orthogroups that have rapidly expanded in H. assulta, while 149 genes in 95 orthogroups have rapidly contracted. This genome draft serves as a valuable resource to explore various aspects of the specialist's biology, enabling research into host-range evolution, chemical communication, insecticide resistance, and comparative investigations with other Heliothine species.

        제비동자꽃(Lychnis wilfordii (Regel) Maxim.)은 주로 고위도의 이탄습지에 분포하는 전문종이다. 우리나라에서는 2개 지역에 고립되어 분포한다. 본 연구에서는 생육지 특성, 생장특성 및 자가화합성 그리고 안정적인 개체군을 유지하고 있는 용늪습지보호지역에서 개체군의 지속에 관여하는 내적 동태를 평가하였다. 분포지의 식생환경은 용늪습지보호지역과 평창군 대관령면 분포지 사이에 뚜렷한 차이가 있었다. 화분매개충의 방문에 의해 종자의 생산이 촉진되기는 하지만 자가화합성을 함께 소유하였다. 토양의 유기물함량이 높은 조건에서 다수의 겨울눈을 생성하였고, 줄기 수, 열매 수가 최대에 달하였다. 그렇지만 유기물함량이 낮은 조건에서도 생장하고 개화하여 종자를 생산하였다. 용늪습지보호지역에서 제비동자꽃은 고층습 원에는 분포하지 않았고 뚝사초가 형성하는 사초기둥이 발달한 저층습원에 분포하였다. 제비동자꽃은 이 공간에서도 사초기 둥의 상단부에 주로 분포하였다. 따라서 뚝사초가 형성하는 사초기둥의 생성, 성장 및 소멸은 이 공간에 분포하는 식물의 정착, 성장, 소멸과 밀접한 연관이 있는 것으로 판단되었다. 현재 용늪습지보호지역은 제비동자꽃이 분포하는 사초기둥이 발달한 공간이 넓게 분포하고 있고 소멸과 재정착의 과정이 잘 이루어지는 것으로 평가되었다. 그러므로 현재와 같은 생태적 과정이 잘 유지된다면 용늪습지보호지역의 제비동자꽃 개체군은 오랜 기간에 걸쳐 지속 가능할 것으로 예상되었다.

        The Sasang constitution typology was analyzed through SCAT2 and a specialist to examine the correlation between the Sasang constitution and dietary pattern, and the difference in BMI and food preference according to Sasang constitution was determined. The Sasang constitution typology of the subjects was classified by SCAT2 and a specialist. Seventy-four subjects were screened by SCAT2 (SC), and 18 of them were judged by the specialist (SP). The results of SCAT2 and the specialist were consistent in 13 subjects (SS). BMI and food preference among these groups were compared. The concordance rate of SCAT2 and the specialist classification was 72.2%. The BMI in SC was significantly lower in the order of Taeeumin, Soyangin, and Soeumin, but no significant difference was observed between Taeeumin and Soyangin in SP and SS. To analyze the preference of food and the constitutional suitability, the ‘Yin-Yang food preference index’ was developed and compared with the data classified by constitutional food according to existing ideological medical theory. As a result, there were 33 food items that matched in the SP-SS, which was more than that in the SC-SP (4 items), SC-SS (6 items), and SCSP- SS (4 items). Twenty-four of the 33 matched food items were consistent with the existing constitutional food data. In conclusion, SCAT2 is a very useful tool for Sasang constitutional research, but for more objective research, it is recommended that subjects who show consistent results by different methods be targeted.

        This paper aims to expand our understanding on the success factors of small businesses, which comprise of more than 90 percent of all businesses in U.S. in 2016. One of the most critical issues behind small business success is the competition, which becomes increasingly intense. Not only small businesses fiercely compete with larger competitors (e.g. Emergence of mega-retailers such as Wal-Mart has intensified the competition in the grocery industry, and, as a result, many mom and pop stores have gone out of business.), but also the competition against each other (i.e. competition between small businesses) becomes increasingly aggressive. Yet, the current literature in marketing have less investigated the issue of competition between small businesses, while issues on competition between small and large businesses have been somewhat explored. Another phenomenon in small business that has not received much attention is the competition between generalist and specialist firms. This phenomenon of specialist versus generalist competition is in fact frequently observed in many industries. Therefore, we study competition between small businesses, focusing on the competition between generalist and specialist small businesses. We examine how competitive intensity, as well as market environmental factors, affect the performance of small businesses. Specifically, we decompose the competitive intensity into two types, one between generalists and the other between specialists, in order to identify the differential effects of competition between generalist and specialist, and examine their impacts on the generalist and specialist performance. Given the research questions above, we develop the following hypotheses based on the past research in marketing. First, we expect competition has a positive effect on generalist performance, while we expect the opposite effect on specialist performance. We also expect that the effect of competition becomes weaker, as the competition becomes more intense. That is, the positive (negative) impact of competition on generalist (specialist) performance becomes less significant as there are more competitors in the market. We further expect that competition between the same type of businesses (e.g. between generalists) has a positive effect on their performance, while competition between the difference types (e.g. between generalist and specialist) has a negative effect on their performance. Moreover, we expect that market environmental factors have differential effects on the performance of generalist and specialist. To test the aforementioned hypotheses on the small business competition between generalist and specialist, we collected data from the health care industry on private physician practices (offices) in Korea. Out data contain, for each practice, monthly sales, number of doctors, number of nurses, type of practice, number of beds and zip code it is located in. We also have data on average consumer spending, average medical spending, percentage of patients over sixty years old for each zip code. Moreover, we have data on competition between the same type of offices (e.g. between generalists and between specialists) and competition between different types (e.g. between generalist and specialist). Note that our data collected from the Korean health care industry fit our research questions well. First, the majority of medical service providers in Korea are small private practices with an average number of two doctors, and the share of generalist and specialist practices are about half-and-half. Second, unlike the U.S. health care industry, generalist physicians in Korea usually practice a number of different fields, while specialist physicians focus on their own specialties. Third, patients in Korea do not usually distinguish between generalist and specialist offices, and they do not usually have a primary care physician. As a result, patients can easily switch between physicians, and in fact the switching is highly likely, as all medical information is centralized by government. Our main findings are as follows. First, we find that competition has a positive effect on generalist performance, while it has a negative effect on specialist performance. Specifically, we find that generalist benefits from competition with both generalist and specialist, while specialist suffers from the competition with both specialist and generalist. As competition becomes intense, meaning the number of physician offices increases, it would attract more patients to visit the area where physician offices are clustered (clustering effect), while it becomes easier for patients to switch from one to the other nearby offices. In particular, as generalist usually treats multiple fields (specialties), generalist tends to benefit from the patients who switch from specialist. In other words, generalists benefit from competition, as they free ride on clustering of physicians including specialists, while specialists would suffer from competition. Second, our findings show that as the competition becomes more intense, its effect on business performance becomes weaker. That is, a high level of competition weakens the benefits and damages imposed on the performance of generalist and specialist, respectively. When there are more physician offices to switch, the effect of free riding becomes weaker, as patients have more options to choose from. Thus, the benefit of generalist from free riding becomes weaker, as well as the negative effect on specialist performance. Moreover, our findings suggest that market environmental factors do influence the business performance. Specifically, the performance of both generalist and specialist improves as the number of doctors increases. However, an increase in the number of nurses has a different effect on generalist and specialist. Employing a larger group of nurses has a negative effect on generalist because it might cause the operation of the office to be less efficient. However, since specialist’s practice usually involves a more technical and sophisticated processes, a larger group of nurses could make the office more efficient having a positive impact on the sales performance. Similarly, we find the effects of other environmental factors have differential impacts on the performance of specialist versus generalist.

        지방자치단체들은 지역축제를 통한 새로운 수익창출 모델 및 홍보를 위하여 자체적인 전담기구 및 추진위원회, 조직위원회 등 많은 기구를 두고 운영 하고 있으며 전문성을 갖춘 이벤트사 및 기획사가 행사를 대행하고 있는 실정이다. 따라서, 많은 축제들이 관주도형으로 이루어지고 있어 지방자치단체장들의 선심성 및 선전용으로만 전락되어 축제의 본질을 벗어나는 경우도 있으며 특히 전문가를 확보하지 않는 상태에서 관 주도형 및 일부 몰지각한 회사들의 이익을 위한 축제들도 많이 등장하여 주민들의 혈세로 진행되는 축제의 예산의 낭비를 초래하는 일도 많아지고 있다. 이러한 문제는 기초가 없는 상태에서이루어지는 일이기 때문에 당연한 결과라고 할 수 있다. 그럼 이 시점에서 제기하고 싶은 것 은 열악한 교육환경이다. 현재 대부분의 4년제 대학교와 일부 전문대학에서는 광고홍보학과에서 축제 이벤트 관련 교육을 일부 다루기는 하나 이벤트 기획을 체계적으로 교육하는 학교가 희박하며, 교육을 할 전문 인력 또한 부재하다. 이벤트 기획 및 실무 교육위주의 교육 프로그램이 절실하며, 대학교와 대학원외 현 이벤트업계 종사자들을 재교육할 전문기관의 설치가 필요한 시점이다. 21세기 첨단 문화산업의 선구자로 우뚝 선 지역축제를 잘 선도하여 전문성 및 독창성을 갖고 각 지자체들의 특색을 잘 살려 관광객들을 많이끌어들여 지방 자립도 확립 및 살기 좋은 고장으로서의 면모를 확실히 갖추어야 할 문제를 전문 교육에서 부터 출발을 해야 할 것이다.

        This study explores an exemplary case of an English immersion program originally initiated by some primary school teachers. It investigates how an immersion education was initiated by the members of an English teachers" study group and later supported by a provincial office of education. The contents of the program and the three examples of immersion classes are briefly illustrated and commented. The innovative endeavors for the successful execution of the immersion classes include the use of the daily morning English practice and various ways of exposing students to English. It was found from the interview conducted with 5 immersion teachers that the strong motivation of the immersion teachers was the first empowering factor for this program and the appropriate financial and administrative help from the provincial office of education was another crucial one. Several practical problems from implementing the immersion program are also reported. From these results and findings some suggestions are made for better ways for implementing immersion programs in elementary schools.

        A survey was conducted to investigate the attitudes of the food specialist to the food developed by gene recombination. The mail survey was distributed to 1,400 food specialists and received 464, a response rate of 33.1%. Respondents were asked about knowledge, concerns of potential hazards, purchasing and labeling of the gene recombination foods. Most respondents (98.7%) have some knowledge on the gene recombination foods. 91.3% of respondents recognized necessity of gene recombination technology. However, they also point out its potential hazards (80.9%). The groups with less knowledge showed their increased worry on the hazard in comparison with ones of having more knowledge(p$lt;0.01). The result indicated that there was negative relationship between knowledge and worry on the gene recombination foods. The groups with more knowledge showed their increased purchasing on gene recombination foods in comparison with ones of having less knowledge(p$lt;0.01). The result indicated that there was positive relationship between their purchase intent for gene recombination foods and knowledge. 68.4% of respondents showed their interest on purchasing the gene recombination foods. In this group, most of them (44.9%) has on condition that low cost (27.0%). In addition, they also have not use the foods for their children (17.9%) if they buy it. Most respondents (85.3%) want labeling on the gene recombination foods.
