It would be the most effective way to have government take care of social problems and hazardous material danger due to odor. It is also well known that odor acceptance and their willingness to pay for resolving the odor problem vary person by person. This is why public sector's intervention is required to get ride of any possibility of market failure resulted from negative external effect of human. This paper has tried to do empirical research based on survey of residents who are currently living in the area of Ochang industrial complex in North Chong-chung province. According to the empirical research results, first of all, it was proven residents' perception of legal regulation has a negative effect on odor acceptance. That is, the more residents are aware of law and regulation, the less they tend to accept odor. In addition, resident's perception on need to improve odor regulation has a positive impact on their odor acceptance. Finally, residents' satisfaction on the legal complaints to local government has an interaction effect to causative relationship between the perception of improving odor regulation and odor acceptance.

This study was conducted to evaluate the allelopathic effect against the regeneration of the seedling and to identify the presence of allelochemicals in Picea jezoensis natural population in Jirisan. Water-soluble extracts from leaves of different competition plants were collected to test their effects on seed germination and seedling growth of P. jezoensis. Phenolic compounds from leaves were quantified using GC/MS. The seed germination rate and seedling growth of P. jezoensis was reduced by extracts of all competition plants leaves. Monoterpenoids compound, which are generally well known in the allelochemicals has been detected in the leaf extracts. In conclusion, allelopathic chemicals of competition vegetation in P. jezoensis natural population could inhibit the seed germination and seedling growth of P. jezoensis, that is considered as a result of the lower seedling establishment.

This study begins with focus on the public opinion and political views on embracing Yemeni refugees in Jeju. The public opinion is demanding amendment or even abolition of the Refugee Act. The argument opposing Yemeni refugees is persuasive enough in terms of public order and safety, cultural conflicts and economic interests, but it is going against the universal and authentic values that must be pursued by a forward-looking society. It is natural that the power exerting political discretion keeps an eye on public opinion. However, no matter how many people express it, unjustified public opinion must not be a foundation for political decision. This study will examine the shadows of public opinion and related concepts for those reasons, and review Augustine's concept of 'love' as a value to refer to in making a communal decision. Conflicts lead to insecurity and rift. Without sensus communis (common sense), the rift will not be healed. This study raises the need to resolve such conflicting state and seeks insight from Augustine.

Alterations in the amount of fibronectin during chick myogenesis were investigated. The amount of fibronectin as measured by immunoblotting was found to decrease during the process. As a first step in answering the precise mode of change in the level of ibronedin during myogensis, the interaction of 28,000 dalton(28 kDa) amino terminal fragment of fibronectin as well as 85,000 dalton (85 kDa) fragrxient with myoblasts was examined. The specific binding of 125 l-28 kDa fragment to myoblasts was time-dependent and reached a maximum within 60 min. Unlabelled 28 kDa fragment inhibited the binding of 125 I-28 kDa fragment, whereas 85 kDa fragment containing adhesion promoting activity did not inhibit it. This finding suggests that the 28 kDa fragment interacts with the matrix assembly receptors but not with the cell adhesion receptors. Accordingly, the decrease in the level of fibronectin is likely to correlate with the fall of fibronectin receptors on the myoblasts.

2019년 3월 기획재정부 장관은 관계부처 합동으로 제2벤처 붐 확산전략을 발표하였다. 신산업 고기술 스타트업 발굴을 통해 기술인재 고기술창업 특히 대학 및 연구소등의 우수 인재가 기술혁신형 창업을 하고, 이에 투자 멘토링 기술 지원하는 사업을 강화하는 한편 지원규모를 확대한다는 계획이다. 2019년 9월 국내 벤처기업 수는 3만6759개이고, 액셀러레이터 투자도 벤처투자로 인정한 '벤처기업육성에 관한 특별조치법' 개정안을 마련하고 있으며, 엑설러레이터 기준을 새로 마련하고 있다. 벤처 투자액은 올해 4조원을 돌파할 거라 예상하고 있는 가운데, 특히 창업의 마중물 역을 하는 액셀러레이터 시장이 크게 성장하고 있다. 대학부터 지자체, 기업, 기존 투자사들까지 뛰어들면서 관련제도가 도입된 지 3년이 채 되지 않아 200곳이 설립됐다. 전 세계적인 스타트업 붐에 더해 진입문턱이 대폭 낮아지자 초기 기업에서 기회를 엿보는 곳들이 늘어난 것으로 보인다. 2017년 54곳에 불과했던 액셀러레이터는 2년이 지나지 않아 4배 가까이 증가했다. 이처럼 시장이 급성장하는 이유는 대기업 중심의 경제 성장세가 둔화되고 우버와 같은 회사들이 새로운 산업을 구축하며 전 세계적으로 스타트업에 대한 관심이 고조되었고, 정부 역시 제2벤처 붐을 일으키겠다며 다방면의 벤처 육성책을 내놓고 있기 때문이다. 이러한 엑셀러레이터에 대한 관심은 학술적이 연구로도 나타나고 있는 바, 엑셀러레이터로부터 투자를 유치한 스타트업의 성과와 관련하여 다양한 원인을 찾고자하는 노력이 시도되고 있다. 스타트업 관계자가 인식하는 엑셀러레이터의 평가지표에 대한 수용성 정도와 그들의 성과 간의 관계에서 엑셀러레이터 조직에 대한 신뢰의 역할을 연구할 필요성이 제기된다고 할 것이다. 제기된 연구 필요성의 해결을 위하여 본 연구에서는 최근 3년 이내 엑셀러레이터로부터 투자 유치를 받은 스타트업 관계자를 대상으로 평가수용성과 엑셀러레이터의 조직신뢰 그리고 성과에 대한 설문조사를 실시하였다. 본 연구의 분석결과를 바탕으로 스타트업 성과를 극대화할 수 있는 엑셀러레이터의 평가지표 구성과 조직측면에서 전략적 방안 모색의 기초자료로 제공하고자 한다.

Records, especially the authentic records the nation secured, have an ontological feature of proof that is able to persuade the current present of the past present, and inherent in it is faith that originates from fundamental objectivity. Therefore the image of silence that such strictness of records creates realizes the detonation of specific memories through the act of visual exhibition. This research started from the notion that records achieve social vitality and return through its exhibition, as well as the critical awareness that it 're-mediate' the past and memory through interactions with image. The reason for viewing the archival exhibition as the subject of user analyzation is that in the process where exhibition sorts and arranges records, it is the tool and mediation that most distinctly exposes the identity of the archives. Hence, this research first analyzes national archives, particularly the exhibition of "presidential" records, which is in the center of memory conflict, in the viewpoint of the cultural practice of memory. Afterwards, it discusses empirical research and results on how users accept and resist the meaning of the exhibition through actual surveys of users after their viewing of an exhibition.

The ectopic expression of gonadotropin releasing hormone(GnRH and luteinizing hormone(LH) in several tissues is a quite intriguing phenomenon. Recently, the presence of GnRH and its receptor has been clearly demonstrated in rodents and human mammary gland. In this context, one can postulate that the presence of local circuit composed of GnRH and LH in the gland. The present study was undertaken to elucidate whether there is a correlation between the LH expression in rat mammary gland and physiological status during the process of mammary differentiation. LH contents in mammary gland from cycling to weaning rats were measured by radioimmunoassay(RIA). In cycling rats, changes of the LH level in both serum and mammary gland showed similar pattern as the highest level in proestrus and the lowest level in diestrus II stage. While the serum LH levels were fluctuated from pregnant through involution stage, a sharp decline of mammary LH contents was observed in the lactating rats. This decrement was recovered in involuting rats to the level of proestrus stage. Reverse transcription-polymerase chain reaction (RT-PCR) and Southern blot analyses demonstrated that the transcriptional activities of the mammary LH and GnRH were increased from diestrus I stage to estrus stage, and the increased levels were maintained in pregnant, lactation and involution stages. To test the hypothesis that the alteration in mammary LH expression might be steroid-dependant, ovariectomy(OVX) and steroid supplement model was employed. As expected, supplement of estradiol(E$_2$) after OVX remarkably decreased serum LH level compared to that in serum from vehicle-only treated rats. Likewise, administration of E$_2$ significantly reduced the mammary LH content. The present study demonstrated that (i) the LH expression in mammary gland could be altered by some physiological parameters such as estrous cycle, pregnancy, lactation and involution, and (ii) ovarian steroid especially estrogen seems to be one of major endocrine factors which are responsible for regulation of mammary LH expression.

Recently, it is more important to study the reasons for using media than which media is selected. This paper investigates different countries as objects to conduct the survey. In accordance with the research results, in hypothesis 1, there is a positive "(+)" influence of its interestingness, informality, restlessness, news pursuit and convenience on satisfaction when college students in South Korea use net news. Taking Chinese college students as an example, there is a positive "(+)" influence of the using motivation of net news on news pursuit, habituation, interactivity, convenience and the satisfaction with net news. In hypothesis 2, the interestingness, informality, habituation and convenience of the using motivation of online news of college students in South Korea are reflected in the acceptance intention of online news, while for Chinese college students, the informality, habituation and convenience are reflected in the acceptance intention of online news. Finally, in hypothesis 3, there is a positive "(+)" influence of the satisfaction of online news on the acceptance level of online news. In addition, this research also considers that the PLS path coefficient of college students in South Korea and China is different, and the motivations and purposes for using net news by two countries are different due to the characteristics and cultures of news media in different countries, so the satisfaction is also different.
