We investigated reproductive cycle of the turban shell. Lunella coronata coreensis with the histological preparation of gonads and the gonadosomatic index (GSI). The turban shells were collected at the intertidal zone of Hamdeok in Jeju-Do from December. 1995 to October. 1996. The gonad was located on the surface of the liver below the stomachal caecum Posterior spiral meat part of the shell. GSI value began to increase from May as water temperature increased and reached its maximum value in August both male and female which were 56.94 and 61.88. respectively. GSI started to decrease from September thereafter. maintaining relatively low value from January to March. The reproductive cycle of L. coronata coreensis could be grouped into five successive developmental stages : multiplicative stage (female: February to April. male. April to May). growing stage (female: April to June, male: June). mature stage (female: June to August, male: July to August). ripe and spawning stave (August to September). And degenerative and recovery stage (October to March). The spawning of the turban shell occurred from August to September and the main spawning period appeared in September. The turban shell. L. coronata coreensis appeared to be gonochoristic species. Sex ratio of female to male was 1.6 : 1.0 (P > 0.05).

마취흰쥐에서 天麻鉤藤飮의 心血管作用에 對한 硏究

배남규,문석재,임동윤,권오성 대한본초학회 1997 大韓本草學會誌 Vol.12 No.2

The present study was attempted to investigate the cardiovascular effects of Cheonmagudeumg-Eum (CMGDE), which is known to be one of chinese medical prescriptions used in treatment of hypertension, in the anesthetized rats and to clarify the mechanism of its pharmacological action, making use of its water extract. 1. CMGDE (5-45 ㎎/㎏), given into a femoral vein of the rat, produced a dose-dependent hypotensive and bradycardic responses while even much larger doses of it (10-90 ㎎/㎏), given into the rectum, did induced negligible hypotensive responses. 2. CMGDE-induced depressor responses were inhibited greatly by pretreatment with phentolamine (an adrenergic α-receptor antagonist), but not by pretreatment with atropine (an antimuscarinic agent) and chlorisondamine (an autonomic ganglionic blocker). 3. Pressor responses evoked by intravenous norepinephrine were attenuated significantly by pretreatment of CMGDE-infusion with a rate of 45㎎/㎏/20min. 4. In the rat aortic strips, phenylephrine (an adrenergic α1-receptor agonist) and high potassium (a membrane depolarizing agent) caused potent contractile responses, respectively. However, in the presence of CMGDE (2㎎/㎖), the contractile responses of phenylephrine (10-5M) and high potassium (5.6×10 exp (-2)M) were markedly inhibited. Taken together, these experimental results suggest strongly that Cheonmagudeung-Eum may cause the hypotensive responses in the anesthetized normotensive rat, indicating that this cardiovascular effects of CMGDE is likely due to the blockade of adrenergic α-receptors without cholinergic effects.

임파워먼트가 조직몰입에 미치는 영향에 관한 연구

배오식,김원 영남이공대학 2001 論文集 Vol.30 No.-

The concept of empowerment has become the focus of much discussion in the organizational management, Despite all the attention empowerment is receiving, a clear definition of the construct is lacking. Furthermore, there have been very few empirical studies investigating empowerment's antecedents and outcomes. The primary goal of this study is to examine the relationships between each of the four dimensions in Spreitzer's multidimensional conceptualization of psychological empowerment in predicting one expected outcomes of empowerment organizational commitment, to review the literature on the four dimensions of empowerment(i.e., meaning, competence, self-determination, and impact), and to test the theoretical logic linking the dimensions to specific outcomes. The results of this study indicated that each of the four dimensions in the multidimensional conceptualization of the psychological empowerment was significantly related to one anticipated outcome of empowerment organizational commitment. Throe dimensions((meaning, competence, and impact) of the four dimensions in the multidimensional conceptualization of the psychological empowerment affect one anticipated outcome of empowerment: organizational commitment, but self-determination did not affect it. Consequently, the results reported in our research suggested that employees need to experience each of the empowerment dimensions in order to achieve organizational commitment.

한오수,안준호,송선희,조맹제,김장규,배재남,조성진,정범수,서동우,함봉진,이동우,박종익,홍진표 대한신경정신의학회 2000 신경정신의학 Vol.39 No.2

연구목적: 정신장애의 정확한 진단과 평가는 임상에서뿐만 아니라 신뢰성 있는 연구를 위해서도 매우 중요하다. Structured Clinical Interview for DSM-IV(SCID)는 임상전문가들이 사용하는 진단도구로서, 비교적 짧은 시간에 정확한 진단을 내릴 수 있다. 본 연구는 한국어판SCID를 개발하고 그 신뢰도를 평가하기 위해 수행되었다. 방법: 국문학자가 포함된 번역위원회를 통하여 연구용판 SCID를 번역한 후, 정신과 의사 2인과 임상심리학자 1인에게 한국어판SCID 실시방법을 교육시킨 뒤 한국어판SCID를 이용한 면담의 평가자간 신뢰도 (interrater reliability)를 검증하였다. 면담 대상은 1999년 2월에서 3월까지 2개 병원 정신과에 치료중인 환자 90명(남:41명, 여:29명)이었다. 결과: 현재 장애(current disorder) 평가에서 주요 우울장애, 기분부전장애, 정신분열병, 알코올 남용 및 의존, 기타 물질 남용 또는 의존, 여러 불안장애들 및 섭식장애 등과 같은 대부분 장애의 kappa값은 .70이상으로 매우 높았다. 그 이외의 양극성 장애, 망상장애, 광장공포증, 감별 불능 신체화 장애 및 건강염려증의 kappa값도 .69에서 .40사이로 수용할 수 있는 정도였다. 평생 장애(lifetime disorder)에서는 양극성 장애(k=.69)와 감별 불능 신체화장애(k=.59)를 제외한 다른 모든 장애의 kappa값이 .70이상이었다. K-SCID 면담시 Ⅰ축 질환에 대하여 흔하게 다중 진단이 내려졌으며, 평균 진단 수는 1.5∼1.7개로 나타났다. 결론: 한국어판 SCID는 신뢰도가 높은 진단도구로 생각되며, 향후 정신질환의 정확한 진단과 임상연구에 유용하게 사용될 수 있다. Objectives: Accurate diagnosis and assessment for psychiatric disorders is crucial for research, as well as for clinical practice. Structured Clinical Interview for DSM-Ⅳ(SCID-RV) is a less time-consumimg and more accurate structured diagnostic interview form. It can be used by clinical professions and is known for a reliable diagnostic tool. Present study was conducted to develop Korean version of SCID-RV and to test the inter-rater reliability. Methods: The authors have translated original SCID-RV into Korean, and revised in parallel with sociocultural background of Korea. Ninety patients from two psychiatric hospitals, both outpatient and inpatient, were interviewed and rated independently by three raters. Results: The kappa coefficients for most of illnesses, such as major depressive disorder, dysthymia, schizophrenia, alcohol abuse and dependency, anxiety disorder and eating disorder were excellent(>0.70) in the evaluation of current disorders. And the kappa coefficients for bipolar disorder, delusional disorder, agoraphobia, undifferentiated somatoform disorder, and hypochondriasis were acceptable(>0.40) in the evaluation of current disorders. In the evalua-tion of lifetime disorders, the concordant rates of all the diagnoses except bipolar disorder and undifferentiated somatoform disorder were excellent. Lack of hierarchy in DSM-Ⅳ allows for multiple Axis I diagnoses. Mean numbers of Axis I diagnoses per subject assigned by the three raters were 1.5-1.7. Conclusions: Our findings confirm that SCID-RV yields highly reliable diagnoses. SCID-RV is recommended for accurate diagnosis in clinical practice and research on psychiatric disorders.

알칼리조건에서 Escherichia coli 0157:H7의 적응 및 항균요법제에 대한 감수성

권오진,배종호 한국식품영양학회 1999 韓國食品營養學會誌 Vol.12 No.6

본 연구는 병원성 Escherichia coli O157 : H7에 의한 감염을 예방하기 위하여 알칼리에서의 적응성과 항균요법제에 의한 불확실성화 효과를 조사하였다. Escherichia coli O157 : H7은 고 농도의 알칼리 (pH 11.5)에 노출 후, pH 9에서의 증식이 pH 7에서보다 좀 더 저항성이 있게 나타나 알칼리에서의 적응능력이 강했다. 이러한 알칼리 적응성은 pH 9에서 6시간 이내에서 잘 나타났다. 한편 Escherichia coli O157 : H7은 항균요법제 중 saicin 과 ceftnaxone에서 감수성이 매우 높았고, 반면, erythromycin과 yosamycin에서는 저항성이 높았다. 또한 saicin과 ceftriaxone에 5∼100kGy로 감마선을 조사하여도 균주의 최소발육저해농도(MIC)에는 영향을 미치지 않았다. Habituation to alkali condition and susceptibility to antimicrobial agents were investigated to determine methods to inactivation Escherlchia coli O157:H7 associated with food poisoning. The investigation showed that Escherlchia coil O157:H7 growth at pH 9.0 was much more resistant to extremes of alkaline pH(11.5) than at pH 7.0. Habituation occurred within 6hr at pH 9_0. The susceptibilities of Escherlchia coli O157:H7 to 13 drugs examined were found highest in regard to saicin and ceftriaxone and lowest in regard to erythromycin and josamycin. No significant changes in minimal inhibitory concentration(MIC) values of bactericidal effect was found when saicin and ceftriaxone were irradiated with doses of 5∼100KGy.

Most mandibulr reconstructions are performed primarily or secondarily for bony defects caused by injuries or removal of tumors. An autogenous bone greft is still the method of choice for the restoration of mandibular defec. But a conventional autogenous free bone graft does not possess an intact blood supply and is dependent on local nutrition to survive. Severely scarred or radiated tissue are unfavorable beds for bone graft and even more the risk of resorption and infection is inceased in these kinds of a pooly vascularized bed. To overcome this difficulty, free vascularized bone graft has been tried with microsurgical gical technuque. A free vascularized bone graft has significantly higher rate of survival, with less resorption and higher resistance to infextion than a connentional free bone graft. A free vascularized iliac bone graft pedicled on deep circumflex iliac vessels is used widely, as it have many advantages such as, availability of large bloc of composite tissue, simplicity of donor dissection, large and long vascular pedicle and few donor site morbidity. In this paper, we represent 4 cases of reconstruction of wide mandibular defects using free vascularized iliac bone graft and free dsteocutaneous groin flap, and review the characteristics of gunshot wound. The result is satisfactory.

Author investigated the growth and developmental status of infants registered in Well Baby Clinic and compared this with the growth standards of Korean and Japanese children. This study group is consisted of 333 infants under 12 months of age with 185 males and 148 females. The following results were obtained: Comparing growth data by sex showed males being superior to females in all measurements and comparing growth data according to breast-fed, bottle-fed and mixed-fed infants showed no significant difference. Comparing body weight with the growth standard of Korean children showed their weights being slightly superior to those of Korean standrrd up to 6 months of age and after then far more superior. Comparing body weight with the growth standard of Japanese children showed that body weights of male infants were superior to those of Japanese standardexcept first 2 months and those of female infants inferior to those of Japanese standard up to 5 months of age and after then slightly superior. Comparing body length with the growth standard of korean children showed that body lengths of male infants were slightly superior to those of Korean standard up to 6 months of age except first 2 months and after 7 months of age far more superior and those of female infants were slightly superior to those of korean standard after 6 months of age. Comparing body length with the growth standard of japanese children showed their lengths being slightly inferior to those of japanese standard up to 7 months of age and after then slightly superior in both sexes. Comparing head circumference with the growth standard of Korean children and those of Japanese children showed their circumfesences being slightly superior to those of Korean and Japanese standard in both sexes.
