한 종에 속하는 개체의 행동 양상은 다양한 변이를 가진다. 같은 종 내에서 다른 행동적 표현형이 유지되는 현상은 진화적으로 적소 특화나 빈도의존성 선택으로 설명할 수 있는데, 아직 명확하게 밝혀진 것은 아니다. 특히 극단적인 행동 양상으로서의 정신병리가 높은 비율로 관찰되는 현상은 진화심리학의 난제 중 하나다. 행동 양상의 다양한 변이 및 정신병리를 진화적인 견지에서 접근하기 위한 몇 가지 틀이 제안될 수 있을 것이다. 본 논문에서는 개체 간 행동 양상 변이에 관한 진화적 접근을 중심으로 동물 모델과 성격 요인모델, DSM-IV 다축 모델, FSD 모델, RDoC 모델 등을 간략하게 설명하고, 그 연구에 적용할 때 예상되는 장단점을 논의하고자 한다.

In recent years, the numbers of the orthodontic dental patients have been rapidly increased in adolescent or young adult aged generation. It has been well known that it would be very hard to control the oral hygiene cares for orthodontic applied dental patient because of the complexity of the appliance. So the caries prevalence of the orthodontic dental patients would be higher than non-appliance persons, and it might be easy to cause the dental caries especially on the labial or buccal surface of the tooth through equipping the fixed type appliance with a long period, even though the alignment of the teeth would be arranged well. So, the massive preventive program for preventive dentistry should be needed for the dental patients for orthodontic treatment, in order to protect the dental caries and the periodontal disease for them. But, lots of the dentists or dental hygienists sometimes neglect of this point for preventive dental cares orthodontic dental patients, or do not know the importance and how to manage the skill for the preventive dental works in clinical. In this article, it will be introduced the basic theories and skills for preventive cares as tooth-brushing instruction, fluoride topical application and pit and fissure sealant, scaling and professional mechanical tooth cleansing and the diet control, for the dental patients with the fixed type of the orthodontic appliance, in case by case.

Drug resistance is an important problem hindering malaria elimination in tropical areas. Point mutations in Plasmodium falciparum dihydrofolate reductase (Pfdhfr) and dihydropteroate synthase (Pfdhps) genes confer resistance to antifolate drug, sulfadoxine-pyrimethamine (SP) while P. falciparum chloroquine-resistant transporter (Pfcrt) genes caused resistance to chloroquine (CQ). Decline in Pfdhfr/Pfdhps and Pfcrt mutations after withdrawal of SP and CQ has been reported. The aim of present study was to investigate the prevalence of Pfdhfr, Pfdhps, and Pfcrt mutation from 2 endemic areas of Thailand. All of 200 blood samples collected from western area (Thai-Myanmar) and southern area (Thai-Malaysian) contained multiple mutations in Pfdhfr and Pfdhps genes. The most prevalent haplotypes for Pfdhfr and Pfdhps were quadruple and double mutations, respectively. The quadruple and triple mutations of Pfdhfr and Pfdhps were common in western samples, whereas low frequency of triple and double mutations was found in southern samples, respectively. The Pfcrt 76T mutation was present in all samples examined. Malaria isolated from 2 different endemic regions of Thailand had high mutation rates in the Pfdhfr, Pfdhps, and Pfcrt genes. These findings highlighted the fixation of mutant alleles causing resistance of SP and CQ in this area. It is necessary to monitor the re-emergence of SP and CQ sensitive parasites in this area.

Coronavirus disease 2019 (COVID-19) has become a major health burden worldwide, with over 450 million confirmed cases and 6 million deaths. Although the acute phase of COVID-19 management has been established, there is still a long way to go to evaluate the long-term clinical course or manage complications due to the relatively short outbreak of the virus. Pulmonary fibrosis is one of the most common respiratory complications associated with COVID-19. Scarring throughout the lungs after viral or bacterial pulmonary infection have been commonly observed, but the prevalence of post-COVID-19 pulmonary fibrosis is rapidly increasing. However, there is limited information available about post-COVID-19 pulmonary fibrosis, and there is also a lack of consensus on what condition should be defined as post-COVID-19 pulmonary fibrosis. During a relatively short follow-up period of approximately 1 year, lesions considered related to pulmonary fibrosis often showed gradual improvement; therefore, it is questionable at what time point fibrosis should be evaluated. In this review, we investigated the epidemiology, risk factors, pathogenesis, and management of post-COVID-19 pulmonary fibrosis.

The prevalence of respiratory diseases is increasing due to social and environmental factors such as increased environmental pollution and air pollution, and among them, chronic obstructive pulmonary disease (COPD) in particular has a high mortality and morbidity rate worldwide. As a result, medical expenses are rapidly increasing, creating a social and economic burden. In response to this, there is a need to discuss ways to reduce the risk from diseases and manage them appropriately, and the most basic starting point in this process is how these chronic lung disease patients are treated in actual clinical settings and how to improve the quality of treatment. There is a need to look into whether there are effective drugs. Western treatment for chronic obstructive pulmonary disease is basically a disease in which the airway narrows, so bronchodilators are used to widen the bronchi, and corticosteroids and antibiotics are mainly used to relieve the inflammatory response in the lungs. However, since the mainly used Western medicine does not serve as a fundamental therapeutic drug and contains many side effects, there is a need for drugs that improve the quality of life of patients and are more effective in managing symptoms as symptomatic prescriptions. Therefore, Western and Oriental medicine treatments are needed. The purpose is to suggest better treatments through comparative analysis.

연구배경: 결핵 감염률은 결핵 실태를 파악하기 위한 기본 지표임에도 불구하고 1995년 전국실태조사를 마지막으로 실시되지 못하고 2000년 결핵정보감시체계로 대체되었다. 비시지 접종률이 높은 현 상황에서 무반흔자를 대상으로 한 감염률 조사는 실행이 어려우며 비시지 접종자를 대상으로 투베르쿨린 조사에 대한 비시지 영향 분석과 비시지 반흔과 상관없는 결핵 감염률 조사가 필요하다. 방 법: 2006년에 전국 초등학교 1학년생들을 대상으로 각 시도별 아동 수를 추계한 후 학교를 대상으로 단면조사 연구를 하였다. 총 대상자 수는 40개 학교의 5,148명이 비례할당법으로 선정, 조사되었다. 투베르쿨린 검사는 2단위의 PPD RT 23 0.1 ml를 좌측 전박에 피내 주사한 후 48~72시간 후에 가장 긴 횡직경을 측정하였다. 비시지 반흔에 대해서도 각각 조사하였다. 결 과: 비시지 무반흔자는 6.3%였다. 평균 경결 크기는 0 mm 반응자 1,882명(46.8%)를 포함하여 $3.7{\pm}4.4mm$ 였다. 결핵 감염률은 10 mm 이상을 양성 반응으로 했을때 10.9% (439명)였다. 연간결핵감염위험률은 평균 연령을 6세로 하여 1.91%였다. 결핵 감염률은 비시지 반흔유무에 따른 유의한 차이는 없었다[11.2% vs. 7.6% (OR:1.54, 95% CI: 0.98~2.43)]. 16 mm를 정점으로 한 거울영상법으로는 감염률과 연간결핵감염위험률이 각각 2.4%와 0.4%였다. 결 론: 결핵 감염률과 연간결핵감염위험률은 기존 방법으로 할 경우 높은 비시지 접종률로 인해 높게 나타났다. 결핵 감염률이 높지 않은 국가에서는 거울영상법이 두 지표를 추정하는데 보다 더 적합한 것으로 보인다.

The estimation of medical care status and the planning of health service program should be done according to each community resident's socio-medical background and public health service. In this point, it is most necessary to be set the exact and new socio-economic statistics data in Nepal, one of the worst countries in national health status. We surveyed 668 house, 3,425 residents in Dolka area, Nepal from January 25th to February 1st, 1995. 1. In personal characteristics, the ratio of men and women was similar, the person who were below 19 years old were 28.1% and the single were 52.4%. The illeterate person were 50.3% and the lower group in economic status which had been estimated by interviewers were 46.9%. 2. In sanitational characteristics, the person who used stream water or rainwater to drink were 42.2% and the person who always boiled water to drink were only 8.3%. The person who had not toilet in their house were 67.3% and the lower group in sanitational status which had been estimated by interviewers were 61.8%. 3. The prevalence rate of illness during the last one month were 8.6% and the chronic were 26.1% and the acute were 72.5%. The distribution of sickness symptom were headache, fever and joint pain in order and the person who took no medical treatment among the sick were 37.0%. The patterns of medical utilization were public health center, hospital and pharmacy in order. 4. Illness prevalence was significantly related to sex, age, merital status and educational experience. The residents who were women, 40 years old or more, married and had not educational experience were apt to take illness. 5. Medical utilization was significantly related to educational experience, job, distance from home to medical facilities and economic status. The person who had educational experience, were officer workers or merchants, lived near by medical facilities and had higher economic status took medical treatment very well.

Background: Severe toxicity is commonly observed in cancer patients receiving irinotecan (CPT-11) UDPglucuronosyltransferase1A1 (UGT1A1) catalyzes the glucuronidation of the active metabolite SN-38 but the relationship between UGT1A1 and severe toxicity remains unclear. Our study aimed to assess this point to guide clinical use of CPT-11. Materials and Methods: 89 cancer patients with advanced disease received CPT-11-based chemotherapy for at least two cycles. Toxicity, including GI and hematologic toxicity was recorded in detail and UGT1A1 variants were genotyped. Regression analysis was used to analyse relationships between these variables and tumor response. Results: The prevalence of grade III-IV diarrhea was 10.1%, this being more common in patients with the TA 6/7 genotype (5 of 22 patients, 22.7%) (p<0.05). The prevalence of grade III-IV neutropenia was 13.4%and also highest in patients with the TA 6/7 genotype (4 of 22 patients; 18.2%) but without significance (p>0.05). The retreatment total bilirubin levels were significantly higher in TA6/7 patients (mean, $12.75{\mu}mol/L$) with compared to TA6/6 (mean, $9.92{\mu}mol/L$) with p<0.05. Conclusions: Our study support the conclusion that patients with a $UGT1A1^*28$ allele (s) will suffer an increased risk of severe irinotecan-induced diarrhea, whether with mid-or low-dosage. However, the $UGT1A1^*28$ allele (s) did not increase severe neutropenia. Higher serum total bilirubin is an indication that patients UGT1A1 genotype is not wild-type, with significance for clinic usage of CPT-11.

Generally working environment and worker's health status of small scale industries (SSI) which employ less than 50 workers are known to be poorer than those of large scale industries(LSI) which employ more than 500 workers. However, according to the analysis of occupational injuries in Korea, prevalence rate of occupational injuries of SSI was 3.1 times as high as LSI. But there was no difference in prevalence rate of occupational disease and werkers with suspected occupational disease(D1) between SSI and LSI. To confirm these two different facts, we surveyed working environment and worker's health status of SSI and LSI in Kyeungin industrial complex. Workers in SSI were 10,878 and workers in LSI were 8,291 and number of hazardous agents in SSI were 3,554 and those of LSI were 1,916. We found following results. First, proportion of male workers and workers who were less than 30 yens old and more than 50 yens old was higher in SSI compared to LSI. Second, worker in SSI had more liver disease, viral hepatitis, and pneumoconiosis than in LSI, and there were more worker with suspected occupational disease, general disease, and worker needed close observation in SSI. But these effects had not statistical significance under the condition controlled by age and sex with logistic regression. Third, the numbers measured for specific chemicals, organic solvents, and heavy metals in SSI was more than in LSI. However there was on difference in the excess rate of each hazardous agent between SSI and LSI. As the above results workers' health status in SSI was poorer than in LSI, but these results were mainly due to the population structure difference. Although there were some limitation of this study and problems of sensitivity and validity for periodic health examination and working environment evaluation method, the concept that working environment and worker's health status in SSI should be reviewed. In future the study that will reveal the real weak point of SSI should be performed.
