In this research, consumer awareness investigation and wearing test were carried out for obtaining useful data on the development of thermo-sensitive functional clothing material. A survey involved 216 people in Seoul and Kyeonggi- do, and 200 questionnaires data were analyzed by descriptive statistics and frequency using SPSS 17.0. Four healthy men in twenties were participated for wearing test. Subjects in normal loungewear were exposed to temperature change from the initial temperature 30oC down to 5oC for an hour in a climate chamber. The environmental temperature, surface temperature of garment and skin were measured. As a result, most of respondents have all season clothing products such as underwear, hosiery, and jogging suit for loungewear. Also, thermo regulator y functional clothes are frequently used as underwear and sweat shirt. The consumer awareness investigation on thermo regulatory functional clothing showed that the most important key buying factor is quick climate temperature response, easy maintenance, design and cost, in that order. Surface temperature of garment went down with the cooling down of environmental temperature. The lower environmental temperature, the greater temperature difference by body part showed. Skin temperature change by environmental temperature showed similar tendency of garment surface temperature. In comparison between garment surface and body skin, temperature difference became larger under the lower environmental temperature.

Objectives : This study aims to estimate the prevalence of the DSM-IV psychiatric disorders in Korean population using the Korean version of Composite International Diagnostic Interview (K-CIDI). Methods : Subjects were selected by taking multi-stage, cluster samples of 7,867 adult household residents, 18 to 64 years of age, in ten catchment areas. Total 78 trained interviewers administered the K-CIDI to the selected respondents, from June 1 to November30,2001. Results : Total 6,275 respondents completed the interview. Some 33.5% of respondents reported at least one lifetime disorder, 20.6% reported at least one-year disorder, and 16.7% reported at least one-month disorder. The most common lifetime disorders were alcohol abuse/dependence (17.24%), nicotine dependence/withdrawal (11.19%), specific phobia (5.16%), and major de-pressive disorder (4.25%). The lifetime prevalence of substance abuse/dependence (0.25%) and schizophrenia (0.16%) was very low. Nicotine and alcohol use disorder showed very high male/female ratio. Mood disorder and anxiety disorder were more prevalent among female than male. Conclusion : The prevalence of psychiatric disorders was high. In comparison with other studies, remarkable differences in distributions of psychiatric disorders across the areas and times were observed.

박충기,안광선,車日煥 연세대학교 산업기술연구소 1977 논문집 Vol.7 No.1

. Fourier transformation is used to analyze a time varying signal in the frequency domain. Due to recent progresses of computer technology, it has been possible to study multitude of time dependet input data effectively and in a relatively short time. The fast Fourier transform (FFT) has been developed for the effective use of computers in dealing with Fourier transform. An elementary theory and general properties of FFT beginning with the Fourier series is presented. It is also shown how to avoid some pit-falls arising in the usage of the FFT. A computer program of FFT for general purpose is developed. As an example of a practical application of this program, the power spectrum of six fundamental vowels of Korean language is resolved.

The critical etiologic factor in the development of dental caries is dental plaque. The main component of dental plaque is the mutan produced by streptococcus mutans. The following results were obtained by using blue mutan to assess the factors affecting the mutan-digesting activity of micromonospora aurantiaca isolated from oral cavity. Micromonospora aurantiaca digested more blue mutan in the minimal essential broth at pH 7.0 than at pH5.5 or 8.5, and at 37℃ than at 32℃ or 42℃. Blue mutan was similarly digested at the range of lmM to 16mM of CaCl₂and 0.1mM to 6.4 mM of MgCl, while being significantly digested at the concentration of 2.5mM of KCL. When the concentration of glucose was decreased in the minimal essential broth, the digestion of blue mutan was increased, When the culture supermatant of Micromonosoira ayrabtiaca in the broth with 1% glucose or 0.5% mutan was mixed with 2× BHLYS broth containing 0.5% yeast extract and 10% sucrose, the formation of artificial plaque on the orthodontic wires by streptococcus mutans was inhibited(p<0.05). These results indicated that the production of mutanase was identified in the culture supernatant of Micromonospora aurantiaca, suppressing the formation of artificial plaque by streptococcus mutans.

본 증례는 50세 여성의 제 1형 신경섬유종 환자로서 척추 신경섬유종에 의해 초기 상완신경총 병변 소견을 보였다. 약 4개월 동안 후경부통, 좌측 견관절, 좌측 상완의 마비를 보였으며, 초기 전기진단학적 검사상 경수 5번과 6번 신경근을 중심으로 쇄골상부 신경절전성 상완신경총 병변이 관찰되었다. 그러나, 액와 자기공명영상, 초음파검사, 단순 방사선검사, 골주사 등의 영상학적 검사에서는 심한 흉추 척추 전-측만증과 경수 뇌경막에 확장 소견을 제외하고는 상완신경총 병변의 소견은 관찰되지 않았다. 7개월경과 후, 좌측 상지 및 양측 하지의 근력 저하, 경수 4번이하의 감각 저하, 경도의 흉통을 동반한 호흡곤란이 진행되었다. 응급으로 시행된 경수 자기공명영상에서 좌측 경수 3번과 4번에 경막내 액와-속질의 신경종양이 진단되었다. 수술적 처치를 시행하였으며, 거시적 관찰상 척수 신경섬유종이 진단되었다. 급격히 진행하는 척수 신경섬유종은 초기에 상완신경총의 신경근 병변의 소견을 보일 수 있으므로, 신경섬유종증 환자에서 상완신경총 병변의 진단에 세심한 주의를 요한다. We observed a patient with symptom similar to brachial plexus lesion caused by spinal neurofibroma in a 50-year-old female with a history of neurofibromatosis-1(NF-1). She presented with posterior neck, left shoulder and left upper arm paralysis of 4 months duration. The initial electrodiagnostic study(EDS) revealed supraclavicular preganglionic brachial plexus lesion of mainly involved left C5 and C6 roots. However, radiological imagings including axillar MRI, ultrasonography, cervical plain radiography and bone scintigraphy showed no definitive brachial plexus disease except cervical dural dilation and severe thoracic scolio-Iordosis. On 7 months after the first admission, she had aggravated muscle weakness on the left upper arm and both lower extremities, sensory impairment below C4 and respiration difficulty with the chest pain. Emergency MRI showed intradural axillar-medullary neurogenic tumor at the left C3-C4. Subsequently, the patient was treated with surgical resection. Grossly specimen examination displayed the presence of a spinal neurofibroma. In rapidly progressing spinal neurofibroma represented firstly as root lesion of brachial plexus in EDS, the physician should pay scrupulous care to evaluate the cause.

본 연구의 목적은 요양보호사 대상의 죽음준비교육이 요양보호사의 DNR에 대한 태도, 피로, 수면의 질에 미치는 효과를 파악하는 데에 있다. 연구의 설계는 비동등 대조군 실험 연구이다. 본 연구는 총청도 J시의 재가노인장기요양서비스 기관에서 2016년 02월 15일부터 5월 30일까지 시행하였다. 본 연구에 대상자는 참여를 동의한 재가노인장기요양서비스기관의 요양보호사 총 43명을 대상으로 하였다. 실험군과 대조군은 각각 21, 22 명씩 무작위로 나누어 배정하였다. 실험군(n=21)을 대상으로 매 회 2시간, 주 1회, 8주간에 걸쳐 죽음준비교육을 실시하였다. 실험 처치 효과는 DNR에 대한 태도, 피로, 수면의 질의 변화를 8주간의 중재 전, 후에 구조화된 설문지를 통하여 측정하였다. 자료의 분석은 t-, chi-square, Fisher Exactand paired t-tests를 사용하였다. 8주간의 중재 후 실험군의 DNR에 대한 태도 (P<.001), 수면의 질(P<.001)이 유의하게 증가된 반면, 피로(P<.030)는 유의하게 감소되었다. 죽음준비교육 프로그램은 요양보호사에게 효과적인 간호 중재로 보인다. 그러므로, 죽음준비교육 프로그램의 현장 적용 가능성을 고려할 수 있겠다. The aim of this study was to investigate the effects of death education on the attitude toward DNR, fatigue, and quality of sleep for generic care worker. This study followed a nonequivalent control group and a non-synchronized design. This study was performed in a visiting generic care service institution in J city, Chung-Cheong province, Korea between February 15 to May 30, 2016. The study included 43 participants who agreed to participate in this study. They were randomly divided into two groups: 21 participants in the experimental group and 22 in the control group. Participants in the experimental group received death education 2 hours per day, once a week, for a duration of greater than 8 weeks. The effect of treatment was measured using a structured questionnaire on the attitude toward DNR, fatigue, and quality of sleep before and after 8 weeks of intervention. Data were analyzed using t-, chi-square, Fisher Exact- and paired t-tests. The experimental group showed a significantly increased attitude toward DNR (p=0.001) and quality of sleep (P<0.001), whereas significantly decreased attitude toward fatigue (p=0.030) than the control group after 8 weeks of intervention. The death education program was shown to be an effective nursing intervention for generic care workers. Therefore, we can consider the possibility of incorporating death education in the nursing program.

NC선반 기어박스의 기어열 : 축계 진동해석 Spindle System for an NC Lathe Gear Box

최영휴,박선균,배병태,정택수,김청수 한국공작기계학회 2000 한국공작기계학회 추계학술대회논문집 Vol.2000 No.-

In this study, two mathematical models are first constructed to analyze vibration characteristics of a gear train - spindle system of an NC lathe gear box. One is a lumped parameter model which is used for calculating natural frequencies of the torsional vibration, the other is a finite element model for analyzing lateral vibration and critical speeds of the spindle system. In addition, this study examines some possible resonance conditions such as gear mesh frequencies, IX shaft rpm frequencies over whole operating speed range, and so on. The results may be helpful to design a machine tool gear box with low noise and vibration.

편모가계와 편부가계의 빈곤개념 : 상대적 빈곤과 주관적 빈곤의 비교적 접근 with Respect to Relative and Subjective poverty

정영숙,박충선 大邱大學校 社會科學硏究所 1998 社會科學硏究 Vol.5 No.4

본 연구에서는 편부모가족의 빈곤문제를 상대적 빈곤과 주관적 빈곤으로 분류하여 분석하였다. 분석결과 편부가족보다는 편모가족의 상대적 빈곤감 혹은 박탈감과 주관적 빈곤감이 더 심각한 것으로 파악되어 이들이 우리 사회에서 경제적으로 빈약한 처지에 있다는 점을 시사하고 있다. 특히 최근의 극심한 경제적 변화는 편모가족의 경제적 안정도를 위협하는 요인으로 작용하고 가계의 취약성을 초래하는 요인이며 이로 인해 이들 가계가 빈곤계층으로 편입될 확률이 크다는 점을 감안할 때 이들을 위해 정부나 지방자치 단체에서는 편모가족이 최소한의 경제적 생활을 할 수 있도록 취업알선 및 기술교육을 제공하고 노동능력이 있거나 자활능력이 있는 편부모에게 산업교육 및 취업기회를 확대함으로써 스스로 자립할 수 있도록 중앙정부와 지방정부의 차원에서 직업훈련 및 취업알선에 관한 서비스가 필요하고, 질병 및 장애로 인해 노동력이 없는 편부모에게는 자녀양육 및 자녀교육과 의료비 보조 등 최저한의 생활을 보장해 줄 수 있는 제도가 정립해야 할 것이다. 본 연구의 결과는 우리 사회에서 편부모가족이나 경제적 취약계층을 위한 빈곤정책의 기초가 될 수 있을 것으로 사료된다.
