본 논문에서는 인체 감지형 자기장 코일의 감지거리 13.4mm를 이용한 디지털 잠금장치 설계에 관한 연구를 하고자 한다. 현재 사용되는 디지털 잠금장치와는 다르게 실외 케이스는 기존의 고유번호 입력버튼, 조명, 보호 커버, 해당 pcb, 외곽 케이스, 데이터 전송 케이블 등이 삭제되고 구동전원 ON/OFF 스위치와 비상 단자로만 구성하였다. 실내 케이스는 내부에 설치 된 자기장 코일기판이 유리문 몸체에 밀착된 상태로 12mm 간격의 맞은편 실외에서 전송되는 전기적 저항 값을 감지하 면 그에 대응하는 유도전류가 흐르게 된다. 이때, 해당 원형 코일의 주파수 변환이 이루어지면 자기장 코일은 센서의 역할을 수행하게 된다. 센서로서의 자기장 코일은 인체가 감지되기 전과 감지 후에 출력되는 발진 주파수의 크기 변화를 감지하고 2,000%이상 증폭시켜 디지털 신호로 변환 조합한 다음 전용 소프트웨어에 전송하여 내장된 고정 데이터와 비교하여 검색하 는 역할을 한다. 연구결과 자기장 코일 12.8Ø 기준으로 인체의 터치 면적에 따른 감지시간은 30% 대비 0.08sec, 80% 대비 0.03sec이며 감지거리는 13.4mm로 최고 수준으로 측정되었다. This study evaluated a digital locking device design using detection distance of 13.4mm of a human body sensing type magnetic field coil. In contrast to digital locking devices that are used nowadays, the existing serial number entering buttons, lighting, number cover, corresponding pcb, exterior case, and data delivery cables have been deleted and are only composed of control ON/OFF power switches and emergency terminals. When the magnetic field coil substrates installed inside the inner case detects the electric resistance delivered from the opposite side of the 12mm interval exterior contacting the glass body part, the corresponding induced current flows. At this time, the magnetic field coil takes the role as a sensor when coil frequency of the circular coil is transformed. The magnetic coil as a sensor detects a change in the oscillation frequency output before and after the body is detected. This is then amplified to larger than 2,000%, transformed into digital signals, and delivered to exclusive software to compare and search for embedded data. The detection time followed by the touch area of the body standard to a 12.8Ø magnetic field coil was 30% contrast at 0.08sec and 80% contrast at 0.03sec, in which the detection distance was 13.4mm, showing the best level

This study was done to examine whether cigarette smoking improved smooth pursuit eye movement(SPEM) abnormalities in chronic schizophrenic inpatients. Fifteen schizophrenic and twelve alcoholic subjects abstained from their usual cigarette smoking for a minimum of nine hours and their baseline performances during the constant velocity smooth pursuit tasks were assessed. Then, the subjects smoked as much as they desired in a 10 minutes period and were retested immediately after smoking and 15 minutes after smoking. Electrooculographic recordings during the eye movements were converted and saved as digitized files. Power spectral density curves and natural logarithm value of signal/noise(Ln S/N) ratios were computed from them. In the schizophrenic patients, Ln S/N ratios increased significantly immediately after smoking compared to baseline. But, Ln S/N ratios showed no statistically significant changes after 15 minutes compared to baseline. In alcoholic subjects, Ln S/N ratios showed no statistically significant changes immediately after smoking and after 15 minutes compared to baseline. In conclusion, SPEM was improved in schizophrenic patients immediately after smoking and we hypothesized that nicotinic receptor dysfunction maybe a candidate mechanism for smooth pursuit eye movement abnormalities in schizophrenia.

본 연구는 정신분열증 환자들을 대상으로 정신건강 및 사회적응력에 미치는 원예치료의 효과를 알아보고자 실시하였다. 자아존중감 및 인간관계측정에서 모두 유의하게 향상된 것을 볼 수 있다. 사회행동척도를 보면 대화의 내용에서는 유의한 결과를 보이지는 않았지만 언어적인 면과 비언어적인 면에서는 유의하게 향상된 결과를 보였다. 간이정신건강진단지 평가를 보면 우울증, 편집증, 정신증 부분에서는 유의하게 호전된 결과를 볼 수 있었다. 또한 대인예민성, 불안감, 적대감, 공포 불안 등에서 호전된 것으로 보였지만 유의한 차이는 나타나지 않았다. 원예활동 평가에서는 참여성, 자아개념 및 주체성, 인지 및 문제 해결능력, 운동자각능력, 숙련도와 직업적응력은 유의하게 향상된 것을 볼 수 있다. 이상의 결과로부터 원예치료 프로그램이 우울 및 폐쇄적인 대인관계를 보이는 정신분열증 환자들에게 심리적, 정서적안정 뿐만 아니라 사회적응력에 효과적이라고 판단되었다. This study was conducted to investigate the effect of horticultural therapy (HT) on the improvement of mental health and social adaptability of schizophrenic patients. Significant effectiveness could be seen in the evaluation of self-esteem and interpersonal relationship. In terms of social behavior scale, there was no significant effectiveness in the substance of conversation. However, effectiveness was improved in terms of verbal and non-verbal areas. Symptom checklist -90- revision evaluation shows a significant improvement in somaticization disorder, obsessive-compulsive, depression, paranoid ideation and psychoticism areas. In evalution of HT, there wes a significant improvement in participation, self-concept and identity, condition and problem solving, exercise perceptivity and life-tasks skill and vocational adjustment. As of the results above, HT program was found to be very effective in psychological stabilization and in social adaptability of schizophrenic patients who tend to be depressed and locked out from human relationship.

Inflammatory fibroid polyps(IFP) is a relatively rare, benign polyp which is composed of fi- brous connective tissue, blood vessels, and infiltration of eosinophils. The majority of inflam- matory fibroid polyps has been reported with pathologic specimen in stomach and small intes tine. Terminal ileal inflammatory fibroid polyps differ from gastric lesion because they are larger and are almost all pedunculated. As a result, they tend to produce intussusception with intestinal obstruction. We present a case of inflamrnatory fibroid polyp of distal ileum causing intussusception with literature review.(Korean J Gastroenterol 1994; 26: 874 878)

P450 CYP2D6 enzyme(=debrisoquine hydroxylase) is known to metabolize many neuroleptics and some genetic polymorphisms in the CYP2D6 gene were reported to be associated with tardive dyskinesia(TD). We investigeted the association of two genetic polymorphisms in the CYP2D6 gene, $CYP2D6^*4$ and $CYP2D6^*10$, with TD in Korean schizophrenic subjects. Subjects consisted of 71 Korean schizophrenics and TD was evaluated using the Abnormal Involuntary Movement Scale (AIMS). There were no statistically significant differences in the demographic variables of age, male to female percentage and the current antipsychotic(CPZ equivalent) dose between the group with TD and the group without TD. But the duration of antipsychotic drug exposure was significantly higher in the group without TD(p=0.000, by independent t-test). The mean AIMS score in the group with TD was $11.2{\pm}6.6$(S.D.). Genotypings for the presence of $CYP2D6^*4$ and $CYP2D6^*10$ were done using PCR amplifications and endonuclease digestions. There were no statistically significant genotypic and alleleic associations between TD and $CYP2D6^*4$(by chisquare tests), and between TD and $CYP2D6^*10$(by chi-square tests). These results indicate that the $CYP2D6^*4$ and $CYP2D6^*10$ polymorphisms have no significant roles in the causation of TD.

Primary multiple cancer means that more than two cancers occur independently in an individual. There have been many reports on primary multiple cancer since Billorth reported it for the first time in 1889. Owing to advancement of diagnostic procedures, reported cases of primary multiple cancers have been increased in number. The most frequent association in stomach cancer was followed by esophagus, larynx, liver, uterus. Here we report 1 case of primary multiple cancer who was a 60-year-old woman with epigastric pain. Endoscopy disclosed white patch and irregular base lesion on the antrum. A CT scan of the abdomen showed a lobulated soft tissue mass in the left kidney. The biopsy specimens showed adenocarcinoma on stomach and renal cell carcinoma on kidney. (Korean J Gastroenterol 1995;27:734 - 738)

Objectives : We investigated the association of Val108/158Met polymorphism on catechol-O-methyl transferase(COMT) gene with smooth pursuit eye movement(SPEM) abnormality in Korean schizophrenia patients. Methods : We measured SPEM in 217 Korean schizophrenia patients(male 116, female 101) and divided them into two groups, one was a good SPEM function group and the other was a poor SPEM function group. Then we analyzed Val108/158Met polymorphism on COMT gene. We compared the differences of genotype and allele distributions of the polymorphism on COMT gene between the two groups. Results : The natural logarithm value of signal/noise ratio(Ln S/N ratio) of the good SPEM function group was $4.39{\pm}0.33$(mean${\pm}$s.d.) and that of poor SPEM function group was $3.17{\pm}0.71$. There were no statistically significant differences of age and male/female ratio between the two groups. There were no significant differences of genotype or allele distributions of the Val108/158Met polymorphism on COMT gene between the two schizophrenic groups. Conclusions : The results suggest that Val108/158Met polymorphism on COMT gene is not related to SPEM function abnormality in schizophrenia.
