  • The proper conditions for cold storage of milt in four species of flatfish were investigated. Various diluents were tested for the preservation of marbled sole, brown sole, starry flounder and olive flounder milt at $1\pm0.5^{\circ}C$ for 7 days. The most effective diluent was $1\%$ NaCl for marbled sole and Stein's extender for brown sole, starry flounder and olive flounder. After 7 days of storage in different dilution ratios (milt: diluent), marbled sole milt diluted with 1:3-10 and brown sole, starry flounder and olive flounder milt diluted 1:1-10 maintained good sperm activity index (SAI). SAI was affected by storage volume and presence of antibiotic. SAI was lower after 7 days storage in the volume of 1.5 mL than in 0.5 or 1.0 mL. SAI after 29 days storage was markedly enhanced by addition of antibiotic in marbled sole (400 ppm gentamicin, 400 ppm neomycin, 200-400 ppm streptomycin), brown sole (600 ppm gentamicin), starry flounder (1,000 ppm gentamicin) and olive flounder (200-1,000 ppm gentamicin, 200-400 ppm neomycin, 200-1,000 ppm streptomycin).

  • It has been one of the puzzles in the English syntax that so called the rule of subject-auxiliary inversion (SAI) is not allowed in subject wh-movement while it is not obligatory in non-subject wh-movement in a root sentence. This asymmetry has been a puzzle since SAI itself was thought to be a part of question construction as we can observe from yes/no questions. The asymmetry gets more complicated in terms of sentence embedding, i.e no SAI is permitted in the embedded context in question. The goal of this paper is to suggest an unified analysis for this unsolved grammatical phenomena on the basis of Rizzi (1997)'s recent work. The main idea is that SAI is not a I-to-C movement but one of I-to-Focus where Focus is a functional category and its phrase is located between CP and IP. The other proposal is that Wh-movement is no more homogeneous in terms of landing site between a root and an embedded sentence: the target for a wh-phrase in the former is the Spec of FocP (Focus Phrase) but the one in the latter is the Spec of CP as the standard theory assumes. Pesetsky (l999)'s analysis is discussed and its theoretical and empirical shortages are pointed out. Its rather radical proposals such as the one that the nominative case is just an uninterpretable tense feature of DP and the other that 'that' is no longer a complementizer but an element of I(nflection) make it less acceptable in spite of the possibility that it can get rid of Case theory entirely, which would be ideal in the spirit of minimalism.

  • 말똥성게 정자의 냉장보존을 위한 여러 가지 희석액의 보존 효과를 비교하였다. 다양한 농도의 포도당 용액, 인공해수(ASW)를 희석액으로 하여 정자를 4$^{\circ}C$에서 보존하였다 보존효과는 정자 활성지수 (SAI), 생존율 및 말똥성 게 난에 대 한 수정률로 평가하였다. ASW와 1.2 M glucose액을 희석 액으로 하여 30일간 냉장보존하였을 때 가장 높은 운동성 및 생존율을 유지하였다. 정자의 냉장보존을 위한 희석액의 적정 pH는 7.0∼8.0 이었다. 정자의 SAI와 생존율을 높이기 위한 항생제로는 neomycin(400 ppm)이 효과적인 것으로 나타났다

  • The aim of this study was to compare the efficacy of cryopreservation methods for ex situ conservation of spermatozoa from far eastern catfish, Silurus asotus. The spermatozoa activity index (SAI) and hatching rates were higher in spermatozoa stored in Alserver's solution than those of spermatozoa stored in glucose solution. The SAI and hatching rates in all experimental groups gradually decreased with increasing duration of storage. Additionally, the SAI and hatching rates gradually decreased with increasing thawing temperatures at all storage durations (P<0.05). Based on the SAI and hatching rates, our results suggest that the optimal cryopreservation conditions of catfish spermatozoa involve storage in Alserver's solution with 15% ethylene glycol, and thawing at $25^{\circ}C$. Cryopreservation of spermatozoa is a useful and reliable technique for conserving gene resources and for artificial propagation of far eastern catfish.

  • Objective : The purpose of this study was to examine the mood disorder, especially depression and anxiety which have an effect on rehabilitation in stroke patients. Methods : Subjects were 32 stroke patients who were inpatients and outpatients at Woosuk University oriental hospital. The degree of depression and anxiety was measured by the Beck Depression Inventory(BDI) and State-Trait Anxiety Inventory(STAI, State Anxiety Inventory : SAI, Trait Anxiety Inventory: TAI). Other questionnaire included sex, age, onset of stroke, degree of education, econommic class, religion, relationship with family, expectancy on treatment, side of hemiplegia, weakness grade of hemiplegia. Results : Results were as follows. 1. The average scores of SAI, TAI and BDI were 45.7, 46.7 and 19.9. The percentages of patients who had relatively high SAI, TAI and BDI scores were 75%(>36 point), 87.5%(>36 point) and 56.2%(>16 point). 2. SAI was correlated with onset of stroke(p<0.05), religion and relationship with family(p<0.1 ), TAI with religion and BDI with weakness grade of hemiplegia(P

  • 12만 개소에 달하는 일본 신사(神社)의 총본산이라 할 만한 미에현 이세시(伊勢市) 소재 이세신궁(伊勢神宮)은 황조신 아마테라스(天照大神)를 모시는 내궁(內宮=황대신궁(皇大神宮)) 과 식물신 도요우케(豊受大神)를 모시는 외궁(外宮=풍수대신궁(豊受大神宮))으로 이루어져 있다. 흔히 천황가의 조상신이라 말해지는 태양의 여신 아마테라스를 제사지내는 신사라는 점에서 역사상 천황과 밀접한 관계를 유지해 왔다. 일본 신도에서 신에게 바치는 음식물 즉 신찬을 다루는 본 연구는 연간 약 1,500회나 거행되는 상기 이세신궁의 마쓰리 중 매일 조석으로 행해지는 일별조석대어찬제(日別朝夕大御饌祭)를 비롯하여 가장 대표적인 대제(大祭)인 신상제(神嘗祭, 간나메사이), 20년마다 한차례씩 행해지는 식년천궁제(式年遷宮祭), 그리고 이와 관련하여 고대 이래현대에 이르기까지 천황이 집전하는 각종 제사 가운데 가장 중요한 신상제(新嘗祭, 니이나메사이) 및 대상제(大嘗祭, 다이죠사이)를 주요 분석대상으로 삼고 있다. 이때 본고의목적은 기본적으로 신찬의 유형과 주요 특징 및 그 신화적 배경과 역사적 변천과정 등을개략적으로 살펴본 후, 구체적으로 상기 마쓰리에 등장하는 신찬의 품목과 절차 등을 검토하면서 궁극적으로 신찬의 사회적, 종교적, 정치적, 문화적 의미를 규명하는 데에 있다. 가령 신도 신찬의 사회적 의미는 농경사회적 특징, 고대 식생활과의 관계, 일본요리와의연관성, 현대사회에 있어 신찬의 의미 및 그것과 관련된 신불(神佛)관념의 문제등을 중심으로 생각해 볼 수 있다. 또한 신찬은 특히 신성, 생명, 재생의 관념과 밀접하게 결부되어 있다는 점에서 그 종교적 의미를 말할 수 있다. 한편 고대일본에서 정치는신에 대한 제사를 뜻하는 '마쓰리고토'라고 불렸으며, 천황의 최대 역할은 바로 신을 모시는 데에 있었다. 다시 말해 일본에서 정치란 신에게 신찬과 공물을 바치고 그 가호를 기원하는 데에서 시작된 것이라 할 수 있다. 이는 신찬이 본래 정치와 밀접하게 연루되어 있었음을 시사한다. 끝으로 본고는 고대 한일간 문화교류의 뚜렷한 흔적을 보여준다는 점에서 신찬의 문화적 의미를 조명하고 있다.

  • Intracranial tumors secondary to radiotherapy are rare. In this group gliomas are the rarest. Only 6 cases of glioblastoma multiforme (GBM) have been reported in patients undergoing radiotherapy (RT) for craniopharyngiomas of which only 4 have been in children less than 18 years of age. In recent years RT has become a mainstay of adjuvant therapy for recurrent or partially excised craniopharyngiomas. We report a child of 12 years who had previously undergone RT for a suprasellar craniopharyngioma and presented 10 years later with a GBM. This is the 5th pediatric case in literature demonstrating a GBM after RT for a craniopharyngioma. The implications of subjecting the pediatric population to RT for a benign lesion versus the outcome of gross total removal and management of RT induced tumors is discussed and the need to avail of safer alternatives such as stereotactic radiosurgery is stressed.

  • In this paper, we will propose the new method that estimates the sensing ability of HH smart sensor. We have developed a new signal processing method that can distinguish among different materials relatively. The HH smart sensor was developed for recognition of materials. We made the HH smart sensor in our experiment. Then, we estimated the ability to recognize objects according to acceleration value. We estimated the sensing ability of HH smart sensor with the $R_{SAI}$ method. Experiments and analysis were executed to estimate the ability to recognize objects according to acceleration value changing. Dynamic characteristics of HH smart sensor were evaluated relatively through a new $R_{SAI}$ method that uses the power spectrum density. Applications of this method are for finding abnormal conditions of objects (auto-manufacturing), feeling of objects (medical product), robotics, safety diagnosis of structure, etc.

  • This paper deals with sensing ability of smart sensor that has a sensing ability to distinguish materials according to surface types of smart sensor. We have developed a new signal processing method that can distinguish among different materials. The smart sensor was developed for recognition of materials. We made two types of smart sensors in our experiment. Then, we estimated the ability to recognize objects according to smart sensor type. We estimated the sensing ability of smart sensor with the $R_{SAI}$ method. Experiments and analysis were executed to estimate the ability to recognize objects according to surface types of smart sensor.
