This study was examined closely physiological activation and intended to present the possibility of developing food low-fat food. Developing carbohydrate fat replacer as materials for low-fat food made of Korean potato starch, it is expected that the new demand of fat replacer will be created. Potato starch was modified by chemical modification. The calorie of starch of GPS was measured to be 3.0 kcal/g, those of chemically modified starch, HPR showed 2.5 kcal/g respectively, suggesting that calorie is decreased by modified treatment. The appropriateness of processing food was experimented by substituting the existing oil and fat containing food with gel of starch and modified starch in constant rate through utilization of modified starch. When producing mayonnaise by substituting edible oil with gel of modified starch in 10-50%, calorie was reduced by 44${\sim}$45% when substituted by 50%, suggesting the potential of low-fat food. Measuring viscosity of mayonnaise by Brookfield viscometer, the mayonnaise with HPR showed high viscosity and the chemical modified starch group of EZ also showed high viscosity. Generally, the material property of mayonnaise tended to reduce in all measured items when oil and fat are substituted by starch substituting materials and the substituting materials increase. When it comes to the emulsification stability of mayonnaise with starch substituting materials, emulsification stability of all mayonnaise with starch substituting materials is lower than that of compared group. While the group with NL as commercial fat replacer showed emulsification stability which was slightly higher than group with modified starch and the substitution group of HPR showed higher emulsification stability. Sensory evaluation for low-fat mayonnaise by substituting oil the products substituted by modified starch was more preferred than general starch substituting products such as GPS. While NL as commercially fat replacer showed the hight preference, products with H40, EZ were also highly preferred.

본 논문에서는 중소기업을 대상으로 모바일 분야 생태계 활성화를 위한 방안을 찾고자 설문조사를 수행하였다. 204명의 모바일 분야 기업 종사자의 응답을 통해, 모바일 생태계 발전의 저해 요인, 모바일 시장 활성화를 위한 요인, 디지털 잠재성 진단을 수행하였다. 국내 모바일 시장 활성화를 위해서 단기적 저해 요인인 시장 구조개선, 자금 지원 등과 활성화를 위한 장기적 지향 요인인 인재 육성, 정부 주도의 지원 역할 강화 등을 고려해 체계적인 지원 전략을 모색해야하는 시사점을 얻었다. 디지털 잠재성 측정 결과, 국내 모바일 중소기업들은 디지털 잠재성의 중요성에 대해 인식하고 있으며, 미래 시장에 대해 어느 정도의 고려와 준비를 하고 있었다. 자사의 제품과 서비스에 적절한 디지털화가 이뤄질 수 있다면, 시장에서 성공시킬 수 있다는 확신과 의지를 가지고 있다는 점을 보여주었다. 반면 디지털 파괴 속에서 기회를 잡기 위해서 국내 중소기업들은 디지털 배달 측면에서 능동적인 접근을 해야 한다는 과제를 얻을 수 있었다.

선천성 면역 반응을 위해 중요한 역할을 하는 TLRs가 외부 병원성 물질에 자극을 받게 되면 NF-${\kappa}$B를 활성화시키며, 그 결과로 염증을 유도하는 COX와 같은 유전자를 발현한다. 이번 연구에서, 옛날부터 지금까지 전통적인 약재로써 질병 치료에 다양하게 쓰이고 있는 감초의 뿌리에서 추출한 성분 중의 하나인 ILG가 NF-${\kappa}$B활성과 COX 발현을 어떻게 조절하여 항염증 효과를 가지고 있는지 알아보았다. ILG는 TLR agonists인 MALP-2, Poly[I:C], 그리고 LPS에 의해 유도된 NF-${\kappa}$B 활성화와 COX-2 발현을 억제시켰다. 또한 ILG는 리간드(ligand)에 독립적인 TLRs signaling downstream molecules인 MyD88, IKK ${\beta}$, 그리고 p65에 의해서 유도된 NF-${\kappa}$B 활성을 억제시켰다. 이러한 결과는 한약재로서 많이 이용되는 감초가 단지 한약의 쓴맛을 줄이기 위함이 아니라 TLRs 신호전달 체계를 조절하여 항염증 효과를 가지고 있다는 것을 보여주는 것이라 할 수 있겠다.

The objective of this study is to analyze the willingness to change into organic blueberry and the activating strategies on domestic products. For the activation of domestic blueberry, it is necessary to get the quality certification, especially organic certificate and develop the technology for increasing production. It is investigated that the smaller product, younger farmer and higher price expected, the higher willingness to change into organic blueberry. The results and finding of this study can be used to build-up the technical and marketing supporting system that reflects the rapid change of customer's preference on blueberry.

Micro duplex stainless steel is used to denote a fine scale two-phase micro structure consisting austenite and firrite. The development of this structure was done by proper thermo-mechanical processing. The objective of present investigation is to study creep characteristics of this alloy. Since we have little design data about the W behaviors of the alloy. An apparatus has been designed and built fir conducting creep tests under constant load conditions. A series of creep tests on them have been performed to get the basic design data and life prediction of micro duplex stainless steel products and we have gotten the 1311owing results. First the stress exponents decrease as the test temperatures increase. Secondly, the creep activation energy Gradually decreases as the stresses become higher. Thirdly, the constant of Larson-Miller Parameters on this alloy is estimated as about 5. Last, the fiactographs at the creep rupture show both the ductile and brittle fracture modes according to the creep conditions.

The objective of this study is to propose activation ways through an analysis on processing actual conditions and quality of farm food. For the analysis we have surveyed the actual condition of farms and conducted sensory test on farm food. Difficulties of farm business are in order to 'preparation of papers', 'facility standard', 'improvement of quality' and 'labeling'. Overall, products from major food companies achieved better results than farm foods in all sensory test. It is necessary to educate the 'Food Sanitation Act' and prepare a manual for the development of farm food.

Coloured wastewater is released as a direct result of the production of dyes as well as from various other chemical industries. Many dyes and their breakdown products may be toxic for living organisms. Activated carbon is one of the best materials for removal of dyes from aqueous solutions. The present study describes the adsorption behaviour of methylene blue dye on three microporous activated carbons, where two samples (AC-1 and AC-2) were prepared by a polymer blend technique and the other is a microporous activated carbon (ARY-3) sample from viscose rayon yarn prepared by chemical-physical activation. The effects of contact time and activated carbon dosage on decolourisation capacity have been studied. The results show that activated carbon having mixed microporosity and mesoporosity show tremendous decolourisation capacity for methylene blue. In addition, the activated carbon in the powder form prepared by the polymer blend technique shows better decolourisation capacity for methylene blue than the activated rayon yarn sample.

The volume of B2C products rapidly increases according to the activation of the electronic commerce. Small and medium electronic commerce companies request the establishment of Parcel Warehouse &Distribution Center(PWDC) that is invested by the post office. This paper presents an economic evaluation method for PWDC from the perspectives fo PWDC and the post office. Two types of warehouses are considered as alternatives for PWDC. One is the conventional warehouse, and the other is the automamic warehouse that is characterized by AS/RS and automatic dispenser system. A benefit/cost analysis method is used to evaluate PWDC since it has the property of public enterprise. A PWDC which will be located in Seoul and adjacent to a concentrated post office is selected as a case study to illustrate the procedure of economic analysis.

Polyclonal antibody of the boar sperminogen was used to characterize the boar sperm proteinase sperminogen. Boar sperminogen was purified from the acid extracts of the washed epididymal spermatozoa by gel filtration through a Sephadex G-100 column. followed by preparative SDS-PAGE. The sperminogen band was sliced out and was eluted from the gel matrix. The purified sperminogen was used to produce the polyclonal antibody of the boar sperminogen. When characterized on a Western blot, the final preparation of sperminogen appeared as a homogenous protein with a molecular weight of 32 kDa. The relative migration of sperminogen was distinctly different from the major components of the proacrosin-acrosin system as well as all the observable proacrosin activation by-products detected on the Western blot. The sperminogen antibody, however. cross-reacted with the proacrosin-acrosin system.
