This study aims to develop a diagnostic tool that can measure nine personality types of the enneagram types based on the theoretical content of enneagram to measure personality as a human factor among various factors that affect to performance for maximizing organization and individual's performance. We have develeped measure items to figure out 9 enneagram types. Since first of September of to 30th August 2011, we had a preliminary survey with total 842 students in zed the data. Based on the results of the analysis of preliminary invmiddle and high school and analyestigation, we made a Enneagram Personality Type Inventory for Young People with a total of 144 selected questions. 4,008 middle and high students across the country were surveyed and had statistical analysis with the data. The data shows Cronbach's α was from .77 to .86 for the 9 types. This diagnostic tool developed with this study will help students can understand, develop and grow themselves, also this can be useful in coaching and counseling areas like Personality, career, academic, career and leadership development.

Cheonggukjang was prepared by addition of peanut (Arachis hypogaea L.) powder in order to improve its quality and functional properties. The physicochemical and sensory properties of Cheonggukjang added peanut powder were investigated, after adding the peanut powder with the amount of 5, 15 and 25% (w/w). The proximate composition of peanut powder was as follows: moisture, 1.80%; crude protein, 24.9%; crude lipid, 48.3%; crude ash, 2.90%; and carbohydrates, 22.1%. Crude protein and lipid content of Cheonggukjang increased with increaes in the amounts of peanut powder, while the moisture content decreased. Calcium and amino acid contents showed disparity depending on the increasing addition of peanut powder. Cheonggukjang containing 15% (w/v) peanut powder was found to be highest calcium contents. The major amino acids of Cheonggukjang were glutamic acid, aspartic acid, lysine, leucine, arginine and proline. Depending on increasing amounts of peanut powder, the L and b values (measured using Hunter’s color values) were decreased, while the a value was increased. In addition, pH was decreased as the amount of peanut powder was increased. Sensory scores of Cheonggukjang containing 15% (w/v) peanut powder were best when considering both quality characteristics and sensory evaluation. This study suggested that peanut powder could enhance the quality and functionality of Cheonggukjang further.

테린 계열의 화합물은 생체 내에 존재하여 여러 가지 효소들의 cofactor로써의 역할을 담당하며, 활성 산소에 대하여 제거 작용을 갖는 비단백질 화합물로서 널리 알려져 있다. 테린 계열의 화합물은 (6R)-5,6,7,8-tetrahydrobiopterin (이하 6-BH4)인 완전히 환원된 형태로 활성을 가지며 공기에 노출되었을 경우 쉽게 산화 형태로 전환된다. 6-BH4의 결핍 증상으로서 정신 질환 관련된 파킨슨 질환, 알츠하이머 질환, 우울증 등의 증상이 있으며, 피부 질환으로는 백반증이 있다. 최근에는 6-BH4의 멜라닌 합성 저해와 관련된 연구가 수행되어지고 있다. 본 연구에서는 6-BH4와 유도체인 (6R)-5-methyl-5,6,7,8-tetrahydrobiopterin (이하 methyl-BH4)의 항산화 효능과 미백 효능 및 자외선 손상 방어 효능에 관한 연구를 수행하였다. 테린 화합물의 DPPH 라디칼 소거능 평가 결과 항산화 표준 물질인 quercetin과 유사한 효능을 갖는 항산화 물질임을 확인하였으며, 피부 세포주에서의 세포 독성이 없는 안전한 물질임을 확인하였다. 또한 미백 효능을 평가하기 위하여 효소 수준에서의 tyrosinase 활성 저해능과 세포 수준에서의 tyrosinase, TRP-1단백질의 발현 저해 효능을 확인하였다. In vivo에서의 미백 효능 평가 결과 역시 증류수 처리군과 비교시 테린 화합물 처리군에서 멜라닌 수치가 감소하는 것을 확인할 수 있었다. 테린 화합물의 또 다른 효능으로서 항산화 효능을 기반으로 하는 자외선 손상 방어 효능을 평가한 결과, 자외선에 의해 유도되는 cytokines의 발현양을 감소시켰으며, 멜라닌의 합성을 저해하는 것을 확인할 수 있었다. 이러한 결과들로부터 테린 화합물의 화장료적 특성을 확인할 수 있었다.

Reuse of industrial effluents through the cooling systems in a petrochemical complex was described. The partial oxidation of the effluents from the biological treatment plant was examined, using Fenton`s reagent as a pretreatment step prior to a next treatment of the effluents. Next tertiary treatment using fixed-film reactor resulted in marked reductions in COD and suspended solids. The continuous fixed-film process with Fenton oxidation pretreatment showed a 23% increase in the COD removal efficiency when compared to that without pretreatment of Fenton oxidation under the volumetric organic loading rate of 0.1 ㎏ COD/㎥/day. The Fenton oxidation treatment seemed to be a possible method for tertiary biological treatment to reduce the residual toxicity with the enhanced biodegradation of the effluents.
