        This study was carried out in order to provide suggestions with regard to optimal control methods for various odor emission facilities (162 companies and 26 industrial classifications) through comparative analysis of effective odor treatment technologies for each type of odor substance by literature reviews, based on measured 22 odor substance data for 162 samples taken from A city. The industrial classification of Pulp showed the highest odor quotient (7,589 as average value) and was followed by the industrial classifications of Wastewater, Woods, and Furniture, indicating average odor quotient values of 2,361, 1,396 and 1,392, respectively. Absorption using chlorine dioxide and sodium hydroxide can be an optimal treatment method to remove the odor substances of sulfide and aldehyde groups. Biofilers with microbial communities will be effective to remove odors caused by volatile organic compounds (VOCs) and an absorption method using sulfuric acid is proper for the removal of odor substances caused by nitrogens.

        The Lactobacillus brevis 340G strain isolated from traditional Korean fermented food (kimchi) produced 15.50mMof γ-aminobutyric acid (GABA) after 48 h of cultivation in MRS media containing 1% L-monosodium glutamate(MSG). The culture conditions of Lb. brevis 340G were optimized for GABA production. Lb. brevis 340G was cul-tivated at 30oC in optimized MRS media containing 3% sucrose and 2% yeast extract with 3% MSG, resulting inmaximum GABA production (68.77mM) after 54 h of cultivation. Skim milk fermented with Lb. brevis 340G pro-duced 4.64mM of GABA in the presence of 1% MSG. These results suggest that Lb. brevis 340G could be usedas a starter for functional fermented foods and skim milk fermented with Lb. brevis 340G could be further devel-oped to become functional dairy food fortified with GABA.

        국내 전통식품 인증을 획득한 된장을 대상으로 간 섬유화 억제를 위한 기능 소재로서의 활용가능성을 알아보고자하였다. 국내 농산물로만 제조되어진 전통식품인증 된장총 24개 제품을 전국에서 수집하여 70% 메탄올로 추출한다음, MEF 세포주에 처리하여 간섬유화의 지표인 α-SMA의 발현 억제활성을 측정하였다. 공장식 생산과정을 거치는 일반 시판된장과 대조군 대비, 경북지역에서 수집된No. 13 전통인증된장 추출물이 약 74%의 α-SMA 발현억제활성을 나타내어 뛰어난 간 섬유화 억제활성을 나타내었다. 이는 의약품으로 사용되는 silymarin 84%과 비교시10% 정도밖에 차이나지 않았으며, 2년 이상의 발효시간을거친 제품임을 감안할 때 향후 발효시기에 따른 기능성의향상에 대한 기대도 가능할 것으로 예상된다.

        Korean logistics industry have been focused on transportation business. However, with the expansion of the electronic commerce and on-line shopping, delivery service is now dramatically growing. Despite the expansion of logistics market, the domestic logistics industry have significant structural problems such as low productivity comparing with the advanced countries, relatively high cost and shortage of human resources and lack of professionalism of people in the industry. Logistics companies reallocate employees, use subcontractors, expand consignment and training the employees to overcome the labor shortages but it has some limits. In recognition of the importance of labor in the logistics industry, financial support and investment have increased. Logistics companies tend to hire consultants, set up logistics department or R&D center in order to establish highly productive logistics process and system so it is viewed that there will be considerable demands of human resources in the logistics industry. This study indicates implications and development direction of human resources in the logistics industry by looking into prospect and characteristic of the industry, employment status, training programs and qualification requirements.
