오징어 가공중의 향기성분의 변화를 알아보기 위하여 Nikerson형 연속추출장치(SDG)를 이용하여 시료의 향기성분을 추출한 후 중성, phenol성 염기성 및 산성획분으로 나누어 중성 및 염기성획분을 GC 및 GC-MS로 분석·동정한 결과 중성획분에서 31성분, 염기성 획분에서 7성분 분석·동정되었다. 오징어 가열시료에서 3-methylthiophene, 2-methyl-2-hexanethiol 등의 함황화합물이 검출되었고 탄소수 5인 1-penten-3-ol, 3-penten-2-ol, 4-me-thyl-3-pentanal 및 탄소수 3인 3-methyl-1,2-propan-diolo, 1-hydroxy-2-propanone과 bexanal,benzaldey-de를 비롯한 탄소수가 8과 9인 alclhol, ketone 등이 검출되었다. 염기성획분에서는 trimethylamine을 비롯한 6종의 pyrazine류가 분리·동정되었으며 2,5-dimethyl pyrazine, 2-ethyl-6-methyl pyrazine, 2,3,5-trimethyl pyrazine 등과 특히 2-ethyl-3,5-dimethyl pyrazine의 함량이 많아 염기성획분의 주된 향기성분으로 나타났다. Volatile components in natural and basic fraction of the steam distillation extraction method from squid during processing were analyzed by GC and GC-MS equipped with a fused silica capillary column. Thirty eight compounds were identified; they were 31 compounds from neutral, 7 compounds from basic fraction. The main components flavor of squid were 3-methylthiophene, 2-methyl-2-hexanthiol, 1-penten-3-ol, 3-penten-2-ol, 3-ethyl-1,4-hexadiene, 1-hydroxy-2-propanone, hexenal and benzaldehyde etc. Especially, (E, E)-3,-5-octadecanal were detected during the boiled. 2,5-dimethyl pyrazine, 2-ethyl-6-pyrazine, 2,3,5-trimethyl pyrazine and 2-ethyl-3,5-dimethyl pyrazine basic compounds, which have respectively a burnt and roasted odor, are considered to be important for the characteristic basic fraction of squid.

기능성식품 원료, 채소, 식물성 소금 재료 및 제염식물 등으로 개발이 유망시되는 염생식물인 나문재의 육지부 재배 가능성을 조사하고, 내륙지방에서의 작물화 가능성을 검토코자 전남 서해안의 염전 부근에 자생하는 나문재의 종자와 식물체를 공시하여 내륙지방인 전남 무안군 소재의 『목포시험장』포장에서 시험하였던 바 그 결과를 요약하면 다음과 같다. 가. 나문재는 식물체를 이식하여도 생육이 양호할 뿐만 아니라 2년 묵은 종 자에서도 발아가 잘되었으며 발아소요 기간은 9일 정도 였고, 나문재의 생육은 소금기가 부족한 내륙에서도 비교적 양호하였으며, 병충해나 기타 재해도 거의 없어 내륙에서의 재배화 가능성이 높은 것으로 인정되었다. 나. 나문재의 생육에 미치는 소금물의 공급 효과를 검토하기 위해 1주일 간격으로 바닷물 농도의 소금물을 공급한 결과, 초장은 소금물을 공급한 것이 공급하지 않은 것 보다 양호하였으나 줄기의 굵기와 분지발생 수 는 소금물 공급효과가 크지 않았다. 다. 나문재의 생체중과 건물중은 종자파종의 경우 7월 10일 현재 소금물 처리구는 각각 주당 33.75g, 2.62g인데 비해 무처리구는 각각 23.52g, 1.84g으로서 소금물 처리구가 무겁고, 생체중에 대한 건물중의 비율은 대체로 7.14∼11.58% 범위로서 수분함량은 92.86∼88.42%정도 되는 다육식물 이었다. 라. 결론적으로 나문재는 소금기가 많은 곳에서 잘 생육할 뿐만 아니라 소금 기가 적은 곳에서도 생육이 비교적 양호하며, 식물전체에 짠맛을 가지고 있으므로 식물성 소금, 기능성 식품, 채소, 그리고 간척지나 음식물쓰레기의 염분제거 식물로서의 이용 가능성 등에 대한 보다 면밀한 검토가 필요하다고 보여진다. The plant of halophyte, Suaeda asparagoides MIQ, which is mainly inhabit on tidal flat was investigated on their growth characteristics and cultural traits on inland condition, in order to get some informations on it's possible use for functional food, vegetables, medicinal herb, and salt removing plant from tideland, or food-waste. The plant, Suaeda asparagoides M_IQ., is well grown on inland condition. But the salt applicated plants were better than those of the non-treated plants in its vegetable growth. The plant height is about 78.5cm in salt application, compared to the 64.5cm in non-treated plot. But the stem diameter and the number of branches are not better in salt application compared to the non-treated ones. However, the fresh weight and dry weight of the plant in salt-application are better than those of the non-treated ones, which means the total biomass is more productive by the salt application. As a conclusion, the plant Suaeda asparagoides M_IQ, seems to be an available plant and need to more discussion for possible use mentioned in the above sectors, from the results of inland cultivation of which well grown and characteristics.

Study on Method of Sperm Aspiration and Injection into an Oocyte in Intracytoplasmic Sperm Injection(ICSI) Immobilization of spermatozoa prior to intracytoplasmic sperm iniection(ICSI) sometimes results in crooked tail and this makes it difficult to aspirate sperm into an injection pipette tail first. Head-first sperm aspiration into an injection pipette avoid this problem due to the bigger size of the sperm head. The effect of head or tail-first sperm injection into an oocyte on fertilization cleavage, percentage of grade I embryos and development to blastocyst stage in ICSI program has been studied. A single living immobilized spermatozoa from oligoasthenozoospermic patient was injected into an oocyte head-first or tail-first according to the treatment. Eighteen hours after microinjection, oocytes ware inspected for survival and fertilization Fertilized oocytes with two pronuclei were cultured in 30μl drop of mHTF supplemented with 10% heat-inactivated follicular fluid(FF) at 37℃. On day 2. embryo transfer was performed with cleaved embryos. The remaining 2-8 cell stage embryos were co-cultured with BRL cells in mHTF + 10% FF for 72 hours and the developmental stage was observed. The data were analyzed by Analysis of Variance. A total of 164 oocytes from 36 cycles were assigned to earth treatment and ICSI was performed(88 head-first, tail-first). The rates of normal fertilization were 81.8% and 76.3% for head-first and tail-first, respectively. Of the fertilized oocytes, the percentage of cleaved embryos and the percentage of grade 1 embryo among cleaved embryos were 88.9% and 68.8%, 93.1% and 74.1% for head-first and tail-first, respectively. Of the 2-8 cell embryos cultured, 44.4%(16/36) and 50.0%(10/20) for head first and tail first, respectively developed to blastocyst stage. There were no differences in fertilization, cleavage, rates of grade 1 embryos, and development to blastocyst stage. In conclusion, head-first or tail-first sperm injection into an oocyte in ICSI program does not affect fertilization and subsequent embryo development to blastocyst stage in vitro.

The purpose of this study was to identify the effect of proprioceptive neuromuscular facilitation (PNF) stretching exercise and joint mobilization on ankle joint range of motion (ROM), plantar pressure, and balance in subjects with stroke. Thirty patients (n=30) were organized into three groups, each of which received different treatments: PNF stretching (n=10), joint mobilization (n=10), and joint mobilization and PNF stretching combined (n=10). Each group received three exercise sessions per week for four weeks. The ankle ROM was measured using a goniometer, and plantar pressure and balance ability were measured using BioResque static posturography. In comparison within each group, the joint mobilization group and the joint mobilization with PNF stretching group showed significant improvements in ankle ROM, plantar pressure, and balance ability (p<.05). In comparison between the groups, a statistically significant difference was found in SECS change between the PNF stretching group, joint mobilization group and the joint mobilization with PNF stretching group. This study found demonstrates that the joint mobilization and joint mobilization with the PNF stretching methods were effective in improving ankle ROM, plantar pressure, and balance ability in stroke patients.

육군은 90년대부터 워게임 모의모델을 활용하여 군단 전투지휘훈련, 전구 연합지휘소연습, 사·군단 작전계획 검증을 하였으며, 현재는 차세대 워게임 모의모델을 개발하기 위한 기술적 검토단계에 있다. 워게임 모의모델의 객체인 가상군을 자동화하기 위한 연구는 오래전부터 진행되었으나, 규칙기반 시스템을 적용한 반자동화군에 대한 연구가 일부 진행된 수준이다. 이에 본 논문에서는 게이머 행동패턴을 기반으로 학습한 인공지능으로 차세대 육군 워게임모델의 대항군 기동부대를 완전자동화하는 방안을 제안하였다.
