This Article examines the main approaches to the public understanding of science(PUS) in light of the changing relation of science and public. Traditional approach called deficit model recognizes scientific knowledge as a entity, unidirectionally diffusing to public. This View basically presupposes the gap between science and public. Meanwhile, this approach has an aspiration to reduce the gap. So there is a paradoxical situation in the traditional PUS. Public perception of environmental crisis and risk of science has been risen since late 1980's. And the science technology studies (STS) have criticized traditional approach. STS proposes new approach of constructive PUS. Constructive PUS conceives the public to have heterogeneous, local characteristic. This approach has been very fertile both in theory and practice. But most recently, newly proposed approach, so called heterogeneous PUS, criticizes constructive PUS. Main point of criticism is that constructive PUS has dichotomy between science and public, and romanticizes the public. It is uncertain whether heterogeneous PUS can take place of constructive PUS. But this trend has the implication that the relation of science and public is constantly changing.
Kim Deuk-yeon(金得硏), who lived at the age of Chosun Dynasty, was the person who kept the parents's will of not serving as a government officias even though he had the ability of serving those positions. He made his composition at the Jisujeong(止水亭), a kind of pavilion which he had built, and the Sijo(時調) Sanjungjapgok(山中雜曲) is one of those compositions. This sugggestes that Sanjungjapgok has a close relation with the Jisujeong(止水亭) which he opreated on his own. So the purpose of this study is focused on analyzing the Sanjungjapgok based on his goal of operating the Jisujeong. The middle age of Chosun dynasty was the era when the pavilion had been prevail even to the average aristocrats who stayed just in local area. Kim Deuk-yeon seems to have had a great endeavor of operating his own pavilion; he had prepared to build Jisujeong for about 30 years. This resulted in his affection of the Jisujeong, which caused him to spend the last part of his life there. Sanjungjapgok consists of 49 pieces of peom and seems to have been written after compositing Jisujeongga(止水亭歌). Even though it has the same title, it doesn't have lots of relations for us to regard this as a Yeonsijo(聯詩調). But this also has the properties of Yeonsijo, whoch contatins 14 Yeonjaksijo(聯作時調) composed of Yeonsijo which has 2 to six lines. The subject of the Sanjungjapgok can be classified as a four major parts: appreciating the nature, study, gathering to make the poem, and taking a rest while satisfied with his own situation. These four properties reflect the function of the private pavilion. In the light of these four properties, I noticed that there were some contents dealing with the private pavilion. Given his social status, I was able to confirm that he had the considerable satisfaction with his life of operating the private pavilion, which was reflected by the Sanjungjapgok.
Paradigm depending only on fossil fuel for building heat source is rapidly changing. Accelerating the change, as it has been known, is obligation for reducing green house gas coming from use of fossil fuel, i.e. reaction to United Nations Framework Convention on Climate Change. In addition, factors such as high oil price, unstable supply, weapon of petroleum and oil peak, by replacing fossil fuel, contributes to advance of environmental friendly renewable energy which can be continuously reusable. Therefore, current new energy policies, beyond enhancing effectiveness of heat using equipments, are to make best efforts for national competitiveness. Our country supports 11 areas for new renewable energy including sun light, solar heat and wind power. Among those areas, ocean thermal energy specifies tidal power generation using tide of sea, wave and temperature differences, wave power generation and thermal power generation. But heat use of heat source from sea water itself has been excluded as non-utilized energy. In the future, sea water heat source which has not been used so far will be required to be specified as new renewable energy. This research is to survey local heating system in Europe using sea water, central solar heating plants, seasonal thermal energy store and to analyze large scale central solar heating plants in German. Seasonal thermal energy store necessarily need to be equipped with large scale thermal energy store. Currently operating central solar heating system is a effective method which significantly enhances sharing rate of solar heat in a way that stores excessive heat generating in summer and then replenish insufficient heat for winter. Construction cost for this system is primarily dependent on large scale seasonal heat store and this high priced heat store merely plays its role once per year. Since our country is faced with 3 directional sea, active research and development for using sea water heat as cooling and heating heat source is required for seashore villages and building units. This research suggests how to utilize new energy in a way that stores cooling heat of sea water into seasonal thermal energy store when temperature of sea water is its lowest temperature in February based on West Sea and then uses it as cooling heat source when cooling is necessary. Since this method utilizes seasonal thermal energy store from existing central solar heating plant for heating and cooling purpose respectively twice per year maximizing energy efficiency by achieving 2 seasonal thermal energy store, active research and development is necessarily required for the future.

In recent days network computing technologies have bee developed rapidly and the extended use of Internet applications for enterprises such as internet/extarnet in and between enterprises has been increased enormously. Therefore the business in the future will be executed by virtual enterprise. Virtual enterprises which is based on information sharing between enterprises are composed of work processes related to information exchange between virtual enterprises, the team members who are representatives of the organizations that are participated in the actual business of virtual enterprises, and members who are representatives of the organizations that are participated in the actual business of virtual enterprises, and environment that are provided by supporting CALS(continuous Acquisition and Life cycle Support or commerce At light Speed). Supporting system of IDE(Integrated Data Environment)for CALS implementation that is provided as an environment of virtual enterprises has to ensure the autonomies of local data and to provide the accessibility of heterogeneous database of enterprises on network transparently for giving user a single global view of data. This paper introduce the design and implementation of the database broker system that can be accessed data transparently by the suers of participated enterprises in the integrated data environment supporting virtual enterprises. The system uses java/CORBA technology in Web environment and Object Query language (OQL) to process the queries of relational database system, object-oriented database system, and file information.
Thirteen InGaAs/InGaAsP separate-confinement heterostructure multiple quantum well lasers were designed such that the strain in the active layer from 0.9% compressive strain to 1.4% tensile, and their threshold current density was caluculated to see the effects of strain on the threshold current density. The well width was adjusted such that the bandgap of the quantum well is 1.55 ${\mu}{\textrm}{m}$, For the calculation of the band structure and transition matrix element needed for the gain calculation, a block diagonalized 8$\times$8 second-order $\to{k}.\to{p}$ Hamiltonian was used to incorporate the conduction band nonparabolicity and the valence band mixing. The threshold current density shows discontinuity at 0.4% tensile strain where the first heavy-hole subband and the first light-hole subband cross and at 0.5% tensile strain where the second conduction subband begins to exist. The threshold current density at room temperature has a maximum around these 0.4-0.5% tensile strains, and as strain varies in either direction it decreases first and then increases a little after a local minimum. This calculated trend is consistent with the other reported experimental results. We discussed the results of this calculation in comparison with other theoretical or experimental papers on the effect of strain.
An 11-year-old, intact male Pekingese was brought to the Veterinary Teaching Hospital of Kangwon National University with a 10-day history of seizures. Fifteen days before coming to Kangwon National University, the dog had visited a local animal hospital for lameness, and non-steroidal anti-inflammatory drugs were prescribed to treat this symptom. However, 10 days before coming to our hospital, the dog experienced generalized seizures. Two days before his arrival, generalized ataxia and mental dullness also occurred. Our examinations revealed no remarkable findings on a routine blood test or X-ray. However, the neurological examinations confirmed mental dullness, generalized ataxia, and a lack of menace response and pupillary light reflexes. Nine hours later, dyspnea occurred, and 12 hours after that, the patient was euthanized per the client's request. A necropsy of transverse sections confirmed the presence of a prominent midline shift due to extended tumor growth. On histopathological analyses, pseudopalisading necrosis of the glial cells and microvascular proliferation were observed. In immunohistochemical analysis, glial fibrillary acidic protein, proliferating cell nuclear antigens, and ionized calcium binding adaptor molecule 1 immunoreactive cells were observed in the tumor area. Based on the results, the tumor was confirmed to be a glioblastoma. Primary intracranial tumors are rare in the veterinary field. This case report describes the clinical and histopathological findings of glioblastoma in a Pekingese.

Maritime air pollutants around port cities have gained a great deal of attention due to their direct impacts on regional air quality. This study aims to determine the geographical properties of sea/land breezes in different areas to discover overall ranges of maritime emission dispersion. The HOTMAC-RAPTAD modeling program was used to simulate regional-scale air dispersion considering non-linear and unsteady states during the general summer period for the target areas of the Yellow Sea (Incheon Port and Pyeongtaek·Dangjin Ports), archipelago region (Mokpo Port), South and East Sea (Busan and Masan Ports) and East Sea with mountainous area (Donghae·Mukho Ports). The resulting dispersion lengths of vessel emissions into the onshore regions around the target ports shed light on portal air quality management, because vessel emissions from the Incheon, Mokpo, Busan, and Donghae·Mukho ports were transported 27-31km (Western Seoul), 21-24km (Southern Muan), 20-26km (Gimhae and Yangsan), and 22-25km (Taebeak Mountains), respectively. Therefore, the results of this study provide useful data for regional air quality management and marine air pollution mitigation to improve the sustainability of port cities.

This study was conducted to determine how the family relationships of the middle-aged affect their life satisfaction and how family support services regulate the association between the two factors. A total of 8,695 middle-aged residents(aged 50 to 64 years) were chosen from among resident-respondents of the needs survey administered to establish the 4th local social security plan in Gyeonggi-do. The moderating effect of family support services on the relation between family relationship difficulties and life satisfaction was investigated. The analysis showed that the life satisfaction experienced by the middle-aged is slightly higher than the middle level. The lower the difficulty in family relationships, the higher the use of family support services, the more women than men, and the better the economy, the higher the life satisfaction of middle-aged. As a moderating variable, family support services significantly moderate the effects of family relationship difficulties experienced by the middle-aged on life satisfaction. The results are meaningful in that they comprehensively shed light on the difficulties that confront family relationships and the relationship structure of family support services, thereby contributing to the search for life satisfaction among the middle-aged in Gyeonggi-do.
This paper studies the influence of multinational R&D Labs' expansion motives on their business performance and the mediating effect of the level of control on this motive-performance relationship. Through an in-depth study of the relevant literature, the expansion motives can be divided into four general types. The first is called a market factor in the sense that the purpose of their expansion is to secure potential markets and customers in China. The second is called a resource factor; their purpose is to obtain excellent technology and a workforce from the country. The third is called an institution factor. An example is the case of R&D Labs advancing into China to make the best of its institutional advantages such as the government's benefits, related policies, and incentive articles. The last is called a strategic factor and indicates the case where they go into China for the purpose of competing in the market, considering it as a major strategic place. The companies' control level on their R&D Labs was measured for each item. According to the empirical analysis on the relevance of their control level and expansion motives, it turns out that giving a free hand to the Labs which pursue market, institutional, and strategic factors is more desirable than highly controlling them. This is because they should be familiar with the local business environment in consideration of those companies' objectives. In light of the mediating effects of the control level on expansion motives and business performance, the R&D Labs pursuing resource factors seem to need their headquarters' control to make the best use of the high-end technology obtained in the country. The companies pursuing strategic factors seem to hold a dominant position and perform more competitively when their headquarters control the Labs more tightly.
A new peanut variety "Pungsan" (Arachis hypogaea ssp. hypogaea L.) was developed at the Yeongnam Agricultural Research Institute, NICS, in Milyang in 2007. It was derived from a cross between a short stem cultivar "Satonoka" and a high-yielding local cultivar "Yecheon". "Pungsan" is the Virginia plant type. It has 18 branches per plant and 40 cm of main stem height. Each pod with long-ellipse shaped large kernel has two grains with light-brown testa and 100 seed weight was 95g in the regional yield trials (RYT). "Pungsan" showed more resistant to web blotch compared with check variety. In the regional yield trials "Pungsan" was outyielded in grain yield to the check variety by 16% with 4.45 MT/ha for grain.
