This study is to investigate the heating value and noxious gases generation such as CO, NO and $SO_2$ known as dangerous gas for human from specimen made of cement and lightweight aggregate. The most quanity of CO gas is generated in EPS(Expanded Poly Styrene), core of commercial sandwich panel. Although specimens mainly composed of cement discharged the relatively less CO gas than organic core such as EPS, specimens which SBR was added discharged the very much amount of CO gas similar to EPS and especially, specimens including foaming agent, gas foaming agent or redipersible powder of VA/VeoVa showed the good properties in the generation of CO gas. From the standpoint of the generation of NO and $SO_2$ gas, both the core of commercial sandwich panel such as EPS, Glass wool and specimens made with polymer dispersion such as St/BA and SBR discharge the very much amount of NO and $SO_2$ gas in comparison of the other specimens. From this study, it was confirmed that organic materials such as core of commercial sandwich panel dischared much more noxious gas than specimens composed of cement and inorganic lightweight aggregate.

Effects of supplemental charcoal powder and vitamin A on growth performance, serum profile and carcass characteristics with 24 Hanwoo steers were inves$\ell$ated. The Hanwoo steers were randomly assigned to one of the three dietary treatments: 1) Control(commercial feed), 2) Tl(commercial feed supplemented with 2% charcoal powder and 0.2 % vitamin A), 3) T2(commercial feed with 2 % charcoal powder). In the age 26 month, body weight of control Tl and T2 were 633.8 kg, 621.0 kg, 619.4 kg, respectively, with not significantly different(P> 0.05). The daily weight gain of control was the highest followed by Tl and T2. The contents of vitamin A(retinol) and total cholesterol in the blood of Tl was higher Tl(56.32 $\ell$ / dt, 163.83 mg/ dz) than the other treatment groups(P < 0.05). The average of WBC value in the blood was 6.86-" 9.83 k / ${\mu}\ell$, RBC value was 7.98 - 11.26 k / ${\mu}\ell$ and blood platelet was 236.7 - 287.0 k / ${\mu}\ell$. But The serum profile in blood was not significantly different between control and treatment groups. The carcass grade and characteristics of all treatments in Hanwoo steers were not significantly different except the texture.

This research was done to develop a standard management checklist for duck farmers. To this end, experts in commercial duck farming participated in making a blueprint for a standard management checklist. This expert group consisted of ten members which included the researcher, a professor, an extension advisor and leading farmers in commercial duck farming. By collecting knowledge on commercial duck farming from these experts, a management performance index was made, and checking factors were designated. As a result of this expert survey, management outcome indicators and subdivision evaluation indicators were established. To confirm these results, a first stage Delphi expert survey was carried out. As a result, the experts were not in agreement with the farming scale of 1 - 4 levels and 2 levels in the management outcome indicators. Additionally, the experts were not in agreement on the choice of feed in the feeding management and the cooperative management system as well as the utilization of agricultural information in managing the business. The factors that did not have the same opinion among experts were surveyed by a second Delphi survey asking whether experts approve the requested value. As a result of the second Delphi survey, all factors have an approval rate that have a value of more than 90%. Finally, a standard management checklist was established based on the research result.

Purpose - Corporate patent management refers to an organization belonging to the government or an intergovernmental organization that plays a bigger role in controlling patents. The purpose of the present study is to investigate and suggest brief solutions regarding how companies should manage their patents, maximizing their commercial values. Research design, Data, and methodology - Since the current researcher needed to optimize authenticity, the datasets were used primarily for collecting data from various sources examined by peers. This research used a claim from PRISMA (preferred reporting items for systematic reviews and meta-analysis) to identify prior studies within the limits of the sample. Result - The results revealed that corporate patent management is faced with different problems in the course of its operations. It faces many different critics from the outside world; therefore, a need to solve those problems. This study strongly suggests there are seven solutions to manage companies' patents. Conclusion - The conclusion of this study points out that The prolonged period has given some business organizations a competitive advantage over others especially that belong to industries that have a lower propensity to adopt patent rights. As a result, some business organizations have grown relatively faster than others within the long period they remain as patent rights members.

본 연구는 역세권의 세력권별 도시공간구조에 따른 지가영향요인분석을 통해 역세권의 거리별 개발방향을 도출하는데 그 목적이 있다. 본 연구의 방법은 선행연구에서 이용한 변수들과 본 연구의 범위별 도시공간구조의 특성을 반영한 변수들로 추출하여 역세권의 거리에 따라 지가에 미치는 영향요인 분석을 다중회귀분석모형을 통해 분석하여 역세권의 세력권별 지가 영향요인의 차이 및 정도를 도출하였다. 분석 결과 역연접권은 상업 중심의 고밀개발, 접근성 및 노후도의 개선 필요성을 도출 하였고 직접세력권은 상업 및 업무 중심의 고밀 복합개발, 접근성의 개선, 상권 활성화를, 간접세력권은 주거 및 상업중심의 복합개발, 노후도의 개선 및 타 이동수동과의 연계성 증대의 필요성을 도출하였다. 본 연구는 역세권의 세력권별 특성 및 차이점을 도출하기 위하여 선행연구의 내용, 분석결과 및 한계점을 토대로 본 연구자의 목적을 도출하기 위한 수단으로 지가를 종속변수로 하여 유동인구, 교육시설 규모, 사회복지시설 규모의 사회적 요인과 건축밀도인 용적율, 지형적요인인 표고, 입지적 요인의 토지이용 및 노후도, 지하철이용인구 및 버스정류장수의 접근성 측면의 독립변수를 설정하여 역세권 세력권별로 지가에 미치는 영향요인을 도출하였다. 도시공간구조가 지가에 미치는 영향 즉, 지가영향요인 분석을 통해 향후 역세권 개발계획 수립 시 중요한 참고자료로 활용될 수 있을 것이라는 결론을 내리게 되었다. 또한, 지가 및 도시공간구조 특성에 대한 한계점을 보완하여 역세권의 개발 방향뿐만 아니라 다른 범위 및 성격의 개발방향을 도출하기 위한 수단으로 활용될 수 있을 것이라 판단된다.

인터넷전문은행의 출범은 많은 변화를 가지고 왔다. 기존 시중은행과 인터넷전문은행이 무한 경쟁을 시작하면서 고객과의 관계유지 혹은 신규고객의 창출이 중요하다. 이를 위해서 고객들이 어떤 측면에서 가치를 지각하는 지를 파악하는 것은 의미가 있다. 따라서 인터넷 전문은행의 출범으로 기존 폰뱅킹 사용자들이 어떠한 태도를 보일 것인지에 대해 실증 분석하였다. 첫째, 시중은행의 기존 모바일뱅킹 서비스특성 중 신뢰성, 이동성이 지각된 전환가치에 영향을 미치며, 반응성은 영향을 미치지 않는 것으로 나타났다. 둘째, 인터넷 전문은행인 제공하는 다양한 혜택이 지각된 전환가치에 미치는 영향을 파악한 결과, 경제적 혜택과 편의적 혜택은 지각된 전환가치에 정(+)의 영향을 미치는 것으로 조사되었다. 마지막으로 지각된 전환가치가 이용의도에 정(+)의 영향을 미치는 것으로 나타났다.

All vague and constructions of contemporary cultural environment have been reorganized and the relationship between people and culture can't follow development speed of rapid material civilization development and being informationalized. Because of the circumstances, physical environment is changing into other cultural environment, existence of human being is at a crisis. Physical value precedes mental value and rapid changing causes culture lag. Modernism design of 20th century suggested standard, simplicity and mass production methods, but nowaday, as human being complexity is increasing, information-media are needed to satisfy that. Namely usual design thoughts have to be changed because our life is surrounded by many kinds of powerful media sings and various mixed cultural circumstances. People predict that the characteristics of new ages are 'Immateriality', 'Sensoriality', 'multimedia'. Amongst them, medial spatial characteristics will be eventually remarkable in commercial space which is coincided with economic logic and multilateral culture. This study is a focus on commercial space which emphasis contemporary medial characteristics and observes medial meaning and various technique through some experimental works in Korea. Also this study's purpose is to examine design directions which correspond with contemporary Korea culture.

Quality characteristics of Yaksik prepared with glutinuous rice soaked for different time lengths were investigated. Moisture contents increased with the increment of soaking time. In Hunter's color value, the lightness decreased and redness and yellowness increased by the increment of soaking time. Samples prepared with a commercial formula showed increased red and yellow colors due to the addition of caramel sauce. The firmness decreased with the increment of soaking time during storage. However, the samples prepared with 2 hr-soaking were retrograded rapidly. In peroxide value, there were no differences among samples. In microbiological evaluation, samples prepared with a commercial formula had prolonged shelf lives probably due to the preservatives contained. Samples prepared with 6 hr-soaking showed the highest score in sensory evaluation.
