We report a 70 year-old man with Binswanger's disease associated with mood symptoms. He was apparently well until 15 years ago when the treatment-resistant atypical mood symptoms had been appeared. He showed a fluctuating course in mental disturbance, such as irritable and labile affect, emotional incontinence, and irritable behavior. Two years ago, he was diagnose as hypertension, renal failure, and heart failure. He was admitted to psychiatric ward due to irritable mood, dysarthria, lack of bladder control, gait disturbance, and impulsive behaviors, which had been aggravated during the last 2 months. In physical examination, he had hypertension and both pretibial pitting edema was revealed, and also in neurological examination, exaggeration of deep tendon reflexes and weakness of extremities were found. On mental status examination, he showed irritable and labile mood with mild cognitive disturbances. Brain MRI demonstrated multifocal high signal intensity in periventricular white matter, both basal ganglia, and thalami on the T2 imaging. These findings were compatible with Binswanger's disease with mood symptoms.

In this study, the frequencies and types of questions about LIFE areas of the Science Curriculum of elementary school students were investigated through in-depth interviews with twelve 4th and 5th graders. The results of the research can be summarized as follows: (1) In conjectural question, the proportions of 'object exploration question' and 'object verification question' were high in all of the 4th graders and the students of low achievement level. (2) The numbers of causal questions generated by the 4th graders were much higher than those of the 5th graders. (3) The frequencies of the predictive, methodological, applicative questions were very low both in 4th and 5th grade students. (4) The numbers of conjectural questions were more in all students except the low achievement level of 4th graders at not-yet-taken contents than at already-taken ones. (5) The numbers of causal questions were more in all students except the low and middle achievement levels of 4th graders at not-yet-taken contents than at already-taken ones. (6) The numbers of the predictive, methodological, applicative questions of the 4th graders were more at not-yet-taken contents than at already-taken ones, whereas opposite trend in the 5th graders. (7) The numbers of students' curriculum-related questions were more in all students except the low and middle achievement levels of 4th graders at not-yet-taken contents than at already-taken ones. (8) As ways for solving or seeking answers about questions, the 4th graders suggested methods of consulting experts or teachers (23.9%), internet searching (21.6%), and books or science-related encyclopedia (20.3%), while the 5th graders suggested the internet searching (36.5%), consulting experts or teachers (24.8%), and books or science-related encyclopedia (17.7%). Based an these results, we suggest several ways for improving the question-posing abilities of the students and adequate use of students' questions in the process of science teaching learning.

Background and Purposes: Over the past three decades, numerous studies performed in Korea have reported that job stress is a determinant risk factor for chronic diseases and work disability. Every society has its own culture and occupational climate particular to their organizations, and hence experiences different occupational stress. An occupational stress measurement tool therefore needs to be developed to estimate it objectively. The purpose of this study is to develop and standardize the Korean Occupational Stress Scale (KOSS) which is considered to be unique and specific occupational stressors in Korean employees. Subjects and Methods: Data were obtained from the National Study for Development and Standardization of Occupational Stress (NSDSOS Project: 2002-2004). A total of 12,631 employees from a nationwide sample proportional to the Korean Standard Industrial Classification and the Korean Standard Occupational Classification were administered. The KOSS was developed for 2 years (2002-2004). In the first year, we collected 255 items from the most popular job stress measurement tools such as JCQ, ERI, NIOSH and OSI, and 44 items derived from the a qualitative study (depth interview). Forty-three items of KOSS, in the second year, were retained for use in the final version of the KOSS by using Delphi and factor analysis. Items were scored using conventional 1-2-3-4 Likert scores for the response categories. Results: We developed eight subscales by using factor analysis and validation process: physical environment (3 items), job demand (8 items), insufficient job control (5 items), interpersonal conflict (4 items), job insecurity (6 items), organizational system (7 items), lack of reward (6 items), and occupational climate (4 items). Together they explained 50.0% of total variance. Internal consistency alpha scores were ranged from 0.51 to 0.82. Twenty-four items of the short form of the KOSS (KOSS-SF) were also developed to estimate job stress in the work setting. Because the levels of the subscales of occupational stress were gender dependent, gender-specific standard norms for both the 43-item full version and the 24-item short form using a quartile for the subscales of KOSS were presented. Conclusion: The results of this study suggest that KOSS might be an appropriate measurement scale to estimate occupational stress of Korean employees. Further and more detailed study needs to be conducted to improve the validity of this scale.

정상체중을 가진 성인 남성에서 지방과다(adiposity)와 심혈관계 질환의 위험요인과의 관련성을 알아보고자 하였다. 2001년 1월 3일부터 12월 31일까지 영남대 학교의료원에서 종합검진을 받은 만 28∼69세 성인 남성 129명을 대상으로 연령, 신체계측, 혈압, 공복 혈당, 혈청 지질대사치와 체성분 검사를 실시하였다. 체질량지수(BMI)가 18.5∼23 kg/㎡(76명)인 정상체중군과 23∼25 kg/㎡(53명)인 과체중군으로 분류하고, 체비방률, 체지방량과 위험인자들(수축기혈압, 이완기혈압, 공복시 혈당, 중성지방, 저밀도지단백, 고밀도지단백)의 상관관계를 분석하고, 정상체중군을 지방과다에 따라 3군으로 나누고, 각 군과 과체중군에서 심혈과 질환의 위험인자를 평가하였다. 정상체중의 제1군을 기준으로 제2, 3군과 과체중군의 위험인자 존재에 대한 비차비(odds ratio)를 조사하였다. 정상체중군에서 지방과다 변수들(adiposity variables: 체지방량, 체지방률)과 수축기 및 이완기 혈압, 저밀도지단백, 중성지방에서 유의한 상관관계가 있었다. (P<0.01). 나이를 보정하고 난 뒤 제1군을 기준으로 제3군(체지방율: 3.7, 체지방양: 4.7)과 과체중군(체지방율: 6.6, 체지방양 11.5)에서 위험인자에 대해 더 높은 비차비를 가졌다. 지방이 많은 정상체중의 성인남성은 적은 지방을 가진 성인 남성보다 심혈관 질환에서 더 높은 유병 위험도를 가졌다. 지방 측정은 정상체중군에서 심혈관계 질환의 위험인자외에 추가적인 정보를 제공할 수 있었다. Background: Most of all studies about the relation between the health risk and obesity are based on the European and American data. The purpose of this study is to examine the relation between adiposity and factors for cardio vacular disease (CVD) in normal weight individuals. Materials and Methods: Normal weight subjects with a body mass index (BMI) between 18.5 and 23 kg/㎡(76 subjects) and overweight subjects with a BMI between 23 and 25 kg/㎡ (53 subjects) were retained for this study. Normal weight subjects were divided into three group of each adiposity variable, then three group and the overweight group were evaluated for the presence of CVD risk factors and analyze the correlation coefficients between adiposity variables and risk factors controlled for age in normal weight, overweight groups. Using logistic regression analysis, the odds ratio (OR) for the prevalence of risk factors for each group of adiposity variables and the overweight group was estimated relative to the first group in normal weight subjects. Results: Systolic BP, diastolic BP, LDL cholestrol, HDL cholesterol, triglycerides in normal weight subjects were significantly correlated with all adiposity variables (P<0.01). Third group (3.7 for %fat and 4.7 for fat mass) of adiposity variables in the normal weight group and the overweight group (6.6 for %fat and 11.5 for fat mass) tended to have higher ORs compared to first group for risk factor variables. Conclusion: Normal weight subjects with elevated adiposity had higher prevalence of risk factors than normal weights subjects with less adiposity. Measuring of adiposity added additional information of cardiovascular disease risk factors in normal weight subjects.

This study was performed to evaluate the effect of resin and filler type on the strength of light-activated composites. Experimental composites were prepared using the four types of urethane tetramethacrylate monomers(HM-4M, TM-4M, XY-4M and DC-4M) and three different shapes of silica fillers. Cylindrical specimens of 3㎜ in diameter and 6㎜ in length and rectangular specimens of 2×2×24㎜ were prepared for the compressive test and 3-point bend test, respectively. All specimens were immersed in distilled water at 37℃ for 24 hours. Compressive and 3-point bend tests were carried out at a crosshead speed of 0.5 ㎜/min and fracture surfaces were observed with scanning electron microscope. The results obtained were summarized as follows : 1. When the size distribution of fillers was same, composites containing the spherical fillers showed the relatively higher loading rate of fillers and compressive strength than those containing the crushed fillers. 2. Compressive strength values of the composites based on UTMA monomers containing the aliphatic UTMA monomers (HM-4M and TM-4M) showed the relatively higher strength values than those of the composites based on UTMA monomers containing the aromatic or cyclohexane ring in their chemical structure(XY-4M and DC-4M). 3. The compressive and transverse strength values of UTMA-based composites were higher than those of Bis-GMA-based composites. 4. According to the microscopic observation of fracture surfaces, composite failure developed along the matrix resin and resin/filler interface region.

External morphological characteristics of male and female of Degeeria separata, which was endoparasited in adult of the Asian ladybird, were studied by using the scanning electron microscopy(SEM). The antenna of Degeeria separata was consisted of three segment and arista. Anstae were about 750㎛ length and 30㎛ in diameter. The surface of antennae was covered with many sensilla. They were long or short, slender or thick, and straight or curved. Each three morphological types of sensilla were observed on the second and third segment of antennae. The mouthpart was sponging type. It was consisted with clypeus, labellum, labium, labrum, and maxillary palp. The labellum is 400㎛ width and double folded vertically. The leg consist of tarsus, tarsus claw, pulvilli, and empodium.

주사전자현미경을 이용한 토마토에 발생하는 아메리카잎굴파리(Liriomyza trifolii)의 외부형태적 특징

윤영남,김기덕,박수진,김남성,서미자,채순용 충남대학교 농업과학연구소 2000 농업과학연구 Vol.27 No.1

SEM을 이용하여 아메리카잎굴파리(Liriomyza trifolii)의 암 ·수컷 성충의 외부형태적 특징을 살펴보았다. 더듬이에 있어 감각모의 3가지 형태는 더듬이가는마디(funicle)에서 관찰되었으며, 모상감각기(trlchold sensillum)는 말단 부위가 뽀족한 특징적인 형태를 하고 있고 감각기들 중에서 가장 많이 분포하고 있다. 원추상 감각기(basiconic sensillum)는 길이가 13㎛, 지름이 1.4㎛에서 1.2㎛인 원형곡선형이다. 홈형 감각기(grooved sensillum)는 간상(peg) 끝에서 나온 손 모양을 하고 있으며, 이 모든 감각기들은 후각과 연관되어져 있는것으로 추정된다. 구기는 홉즙형으로 작고 펼쳐진 윗입술(labrum)과 합쳐져서 하나의 연결된 주둥이(rostrum)을 형성하고 있다. 가느다란 한 쌍의 작은턱수염(maxillary palp)은 긴 관 모양으로 각각의 세로로 이어져 있다. 발마디는 5마디로 이루어져 있으며 그 한가운데에는 패드모양의 흡착반(pulvillus)과 가시모양의 발톱사이돌기(empodium)가 있다. 아메리카잎굴파리는 흡착반과 발톱사이돌기에서 미끄러운 표면에 부착할 수 있는 물질을 분비한다. 수컷의 생식기는 매우 복잡하며 삽입구(aedeagus)는 생식기관으로서 가장 일반적인모양이다. 반면에 암컷의 생식기는 상대적으로 간단한데 이 구조는 외부로 돌출된 관모양이었다. 또한 이러한 결과를 이미 발표된 다른 여러 종의파리와 비교하였다. The external morphology of male and female of Liriomyza trifolii (Burgess) was studied using the scanning electron microscopy (SEM). Three types of sensilla were identified on the funicle of antennae. The trichoid sensilla were most conspicious and distributed with a characteristic sharp structure at the apical end. Basiconic sensilla were showed distal curvature about 13㎛ long and 1.2㎛ to 1.4㎛ in diameter. Grooved sensilla were showed a finger-like projections at the peg apex. The function of these sensilla likely to be olfactory. The mouthparts were adapted for sucking food, and formed a elongate rostrum which was incorporated with labrum. The labrum was a small and flap-like shape. The slender and paired maxillary palp seemed to combine with each other lengthwise to long tube. The tarsus typically consisted of 5 segments, which might be variously modified, principally by thickening or flattening. The segment healed a pair of claws. Beneath the claws, there was a pair of pad-like pulvillia and a bristle-like median empodium. L. trifolii secreted on the pulvillus and empodium an adhesive substance that enable them to cling to smooth surfaces. Male terminalia was complicated. The name 'aedeagus' seemed the best available general term for the copulatory organ, otherwise, female terminalia was usually relatively simple. This structure was reduced and formed a telescopic, eversible, and tubular ovipositor.
