Infectious diseases imported from other countries have increased as more and more Koreans are going abroad for various purposes. Tsutsugamushi disease from other endemic area such as Southeast Asia is important, because it can occur in any season and eschar may be absent. We report a case of imported tsutsugamushi disease acquired in the Philippines. A patient presented with fever, headache, and maculopapular skin rash. However, eschar was absent. Polymerase chain reaction (PCR) for 56-kDa gene of Orientia tsutsugamushi using buffy coat was positive. Serum indirect immunofluorescent antibody assay was initially negative but became positive with a titer of 1:320 at follow-up, Sequencing analysis revealed the strain to be 100% identical to the TW73R strain identified in Taiwan. After the patient received doxycycline, body temperature normalized in 12 hours. Tsutsugamushi disease is one of the differential diagnoses that should be included for patients with fever who have recently returned from Southeast Asian countries. PCR for O. tsutsugamushi using patient's buffy coat was useful for early diagnosis.

This paper deals with the speed control of a BLDCM with rectangular back electromotive force using fuzzy logic controller. The fuzzy PI controllers make the many degrees of freedom in proportion to the number of the rule for input and its ability of adjustment for control input is excellent. Thus, the proper adjustment of the fuzzy rules can provide the good performance for the system. Above all, the advantage of the fuzzy controller has the characteristic of robustness for parameter variation, load change, noises. As a current controller, a hysterisis current controller is implemented, and in order to reduce torque ripple in low speed range, current controller detects the uncommutating mode current for every 60 electrical degree. The fuzzy speed controller is implemented by MCS80C196KC, a 16 bit one-chip microprocessor. The experimental results show that the performance of the fuzzy speed controller is superior to that of the conventional PI controller in terms of robustness for the change of load torque.

Hearing impairement in varying degrees constitutes one of the most common disabilites affecting school aged children. Eight out of every 1,000 students under the age of twenty have significant hearing loss. Hearing disabilities range from slight to total loss of sound perception. Statistics indicate that only one out of every ten hearing impaired children will become deaf. Most motor activities can be included students may possess low levels of static and/ or dynamic balance, but the greatest majority possess normal motor and physical capabilities. All the hearing impaired youngsters should be properly assessed and given the identical testing batteries as normal children. Hearing impaired students have, essentialy, a communication handicap and suffer from inability to understand verbal instructions. All physical educators should be able to use minimal finger spelling and signing for hearing impaired students.

1. Introduction Governmental policies should receive strong support from the general public to be effectively implemented. Therefore to find some clue as to how public policies might receive nation-wide support is very important. As the research objective was to find some factors which effect degree of policy acceptability, we interviewed 1,179 persons(633 citizens of Tae-gu city and 546 persons from rural communities in Kyung-puk Province) from July 10 to August 20, 1973, by stratified sampling. Stratifying criteria were sex, age, financial assets and educational background. X^2 was used as a tool to test the hypotheses that there may be differences in values and degree of policy acceptance among persons of different strata and that there may be differences in degree of policy acceptance among persons who have different values. 2. General Tendency Forty percent of those interviewed choose the item "None" among the choices to the following question; Question; Which one do you choose, if you can choose only one of three? Answer; 1) Money or wealth 2) Power 3) Honour 4) None Let us call the persons who choose 1) "Money-oriented" and so "Power-oriented", "Honour-oriented". More persons interviewed preferred a self-restraining life to a hedonistic life, and egoistic, to altruistic. Egoists here means the persons who choose item 1, 2, 3, and altruists, 4 and 5 in the following question; Question; For whom do you think you live? Answer; 1) My-self 2) Children 3) Ancestor 4) Community 5) Nation or country More persons believed that the moral order of a society is more important than economic affluence. Almost seventy percent of the interviewed preferred that public policies be formulated for a better future life for the people than for immediate present well-being. Economic policies including those for increasing national income and increasing export were believed to be goood and effective in their implementation. However, taxes were regarded as too heavy. This shows that people rely much on the government for economic development on the one hand, but do not recognize their responsibilities to support those governmental efforts through taxes on the other. The Sae-Ma-Ul movement received as strong support as the economic policies and city development policies received sufficient support. But educational policies such as school expenses and ethics and moral education were denounced, as were the public health policies. 3. Differences among Strata ⑴ Region: people of rural communities regarded power and honour with more value than their urban counterparts, while urban people were more money-oriented. Rural people accepted tax policies more readily than did urban people, but they denounced the public health policies and educational policies mentioned above more severely than urban people. ⑵ Sex: men were more power and honour-oriented than women. Men preferred the moral order of scociety more than women, while women preferred economic affluence more than men. Export increasing policies, public health policies and school expense policies were accepted more readily by women. However, city development policies were accepted more readily by men. ⑶ Education: the more educated persons were more honour-oriented, emphasized the moral order of society and the better future life of the people more strongly than less educated persons. All these reflect the effects of moral education. However, from non-educated persons to high school graduates, the more educated the more money and power-oriented they were, while college graduates were far less money and power-oriented than middle or high school graduates. This points out the good effects of college education and some problems of middle and high school moral and ethics education. The more educated regarded the present compulsory educational system as more effective and school expences less expensive than the less educated. However, college graduate gave less support to the new school entrance system, while they gave the highest support to the Sae-Ma-Ul movement. ⑷ Age: the older persons emphasized the moral order of society more frequently and showed more political apathy than younger persons. They also accepted the public health policies more readily than the younger people. ⑸ Assets: the richer persons were more honour-oriented and regarded school expenses as less expensive than the poor persons. 4. Correlation between Values and Policy Acceptance ⑴ Money-oriented persons(who choose Money among given items of Money, Power, Honour and None) were much more egoistic (mentioned above in General Tendency) than the honour-oriented persons. ⑵ Honour-oriented persons accepted more readily than the money-oriented persons policies for increasing national income, reestablishing law, moral order and a better atmosphere of a society and the Sae-Ma-Ul movement (three of five policies analized in detail to test our hyphotheses about correlation between people's values and the degree of policy acceptance). Altruists supported policies for increasing national income and city development policies more strongly than the egoists. Therefore we assume that honour-oriented persons or altruists accept the public policies more readily than money-oriented persons or egoists.

Diabetic foot infection is one of the important complications in patients with advanced diabetes mellitus. Limb threatening infections such as osteomyelitis, abscess, and necrotizing fasciitis are frequently accompanied by the disease. Non-tuberculous mycobacterium (NTM) is a rare causative organism of diabetic foot infection. Thus, if one is not suspicious or meticulous, infection due to NTM will be easily overlooked and this will result in delayed diagnose and treat. Therefore, it is necessary to consider NTM as the causative organism if the wound does not respond to the conventional antibiotic treatment and the culture from the adequately obtained specimen reveals atypical acid-fast bacilli. We present a case of diabetic foot infection with osteomyelitis and abscess due to Mycobacterium mageritense, one of the rapid growing mycobacteria, that was successfully treated with surgical debridement and appropriate antibiotic treatment.

김지연,이태희,박재홍,정민영,양승원,정동진,김명수,김정민,이정훈 대한당뇨병학회 1998 Diabetes and Metabolism Journal Vol.22 No.1

연구배경: 당뇨병 환자에서 동맥경화증의 발생위험이 정상잉인에 비해 높은 원인의 하나로써 혈액응고와 섬유소용해작용의 이상을 초래하는 Lipoprotein(a) [Lp(a)]가 논의되고 있다. 당뇨병 환자의 동맥경화증과 당뇨병성 합병증 발생위험 증가에 Lp(a)가 어느 정도 관여하는지에 대해서도 아직 확실히 알려져 있지 않다. 저자등은 인슐린비의존형 당뇨병 환자의 혈관합병증(대혈관 및 미세혈관합병증) 발생과 Lp(a)농도와의 관계 및 혈관합병증을 일으키는 다른 위험인자와 Lp(a)농도와의 관련성에 대하여 알아보고자 본 연구를 시행하였다. 방법: 인슐린비의존형 당뇨병 환자 152명(여자:남자=72:80)을 대상으로 공복상태에서 혈중 Lp(a), ApoA1, ApoB, 총 콜레스테롤, 중성지방, 고밀도지단백질-콜레스테롤 등을 측정하였다. 대혈관합병증(허혈성 심질환, 뇌혈관질환, 말초혈관폐쇄성 동맥경화증)의 진단을 위해 증상이 있는 환자들에서 심전도, 관상동맥조영술, 뇌전산호단층촬영, Doppler velocimetry, 말초혈관조영술 등을 시행하였고, 미세혈관합병증은 안저활영, 신경전달속도, BBV(beat to beat variation), VPT(vibration perception threshold), 24시간 요단백량 등을 측정하여 확인하였다. 결과: 허혈성 심질환, 뇌혈관질환등 대혈관질환 및 당뇨병성 망막증 등 미세혈관질환을 갖는 환자에서 Lp(a)농도가 대조군보다 통계적으로 유의하게 증가되어 있었다. Lp(a)농도가 30㎎/dL이상인 군에서 ApoB/ApoA1 및 저밀도지단백질-콜레스테롤이 Lp(a)농도가 30㎎/dL 이하인 군보다 높았으며, 혈관질환을 갖는 군에서 Lp(a)는 높은 ApoB/ApoA1와 저밀도지단백질-콜레스테롤과 통계적으로 의의있는 양의 상관관계를 보였다. 결론: Lp(a)는 인슐린비의존형 당뇨병 환자의 대혈관합병증과 미세혈관합병증(특히 당뇨병성 망막증)에 관련이 있는 것으로 보이며, 특히 저밀도지단백질-콜레스테롤 및 ApoB/ApoA1이 높게 나타난 인슐린비의존형 당뇨병 환자에서 Lp(a)농도 측정이 필요하리라 생각된다.

송경호,김계형,김충종,박경운,전상훈,김홍빈,김남중,오명돈,최강원 대한감염학회 2007 감염과 화학요법 Vol.39 No.5

Good 증후군은 흉선종과 면역결핍이 동반되는 질환으로, B세포의 감소로 인한 범저감마글로불린혈증과 CD4^(+)T세포의 감소로 인한 세포성 면역저하가 동시에 나타나는 것을 특징으로 한다. 본 증례는 18개월 전부터 발생한 반복적인 부비동염을 주소로 내원한 43세 남자 환자로, 내원 1년 전 흉선종절제수술을 시행받았으며, 면역학적 검사상 범저감마글로불린혈증과 T세포의 감소 등의 이상 소견이 발견되었다. 정주 면역글로불린과 경험적 항생제(amoxicillin/clavulanic acid) 사용 후 부비동염이 호전되었으며, 예방접종과 정기적인 면역글로불린 투여 후 특이 합병증없이 경과 관찰 중이다. Good's syndrome is the association of thymoma with immunodeficiency, characterized by hypogammaglobulinemia, B-cell lymphopenia and variably defects in cellular immunity with CD4^(+) T-cell lymphopenia and an inverted CD4^(+):CD8^(+) T-cell ratio. We report a 43-year-old male patient who presented with a 18-month history of productive cough and postnasal drip. One year ago, he underwent the operation for resection of a thymoma. Despite of appropriate management, sinusitis relapsed multiple times. He was found to have hypogammaglobulinemia with nearly absent B cells(4/μL). The CD4^(+) T-cell count was 554/μL with an inverted CD4^(+):CD8^(+) T-cell ratio of 0.6. His symptoms and signs improved with antibiotic treatment and monthly administration of intravenous immunoglobulin (IVIG, 400 mg/kg).

Objectives : The aim of this study was to examine the behavioral and emotional problems associated with nocturnal enuresis in Korean children. Methods : Three hundred eighteen children with nocturnal enuresis, together with their parents, completed the Child Behavior Checklist (CBCL), Disruptive Behavior Disorder Scale according to DSM-IV (DBDS), Children's Depression Inventory (CDI), State-Trait Anxiety Inventory for Children (STAIC), and Piers-Harris Children's Self-Concept Scale (PHCSC). Ninety-three normal students were selected as the control group. Results : Compared to the normal control group, the mean scores with regard to the withdrawn, social problems, attention problems, delinquent behavior, aggressive behavior, externalizing problems and total problems profiles were significantly higher in the nocturnal enuresis group according to the CBCL results. The nocturnal enuresis group also scored significantly higher in the ADHD and ODD profiles of the DBDS. The nocturnal enuresis group was more depressed and anxious than the control group according to the results of the CDI and STAI. The mean score of the PHCSC was significantly lower in the nocturnal enuresis group when compared to the normal control group. Conclusion : The results of this study suggest that children with nocturnal enuresis in Korea have clinically relevant behavioral and emotional problems. The findings support the link between nocturnal enuresis and psychopathology in Korean children.
