강남에 사는 사람들은 '세금 폭탄'을 맞았다. '우리가 봉이냐'며 불만 가득한 표정이 역력하다. 올해는 종합부동산세가 2배 가까이 늘어날 예정이어서 강남에 집을 소유한 사람들은 애간장을 태우고 있다. 강남 일대 아파트 시장의 반응과 시세 동향 그리고 몇몇 아파트의 종합 부동산세와 보유세를 직접 계산해보면서 납부할 세액이 어느 정도 될지 살펴보자.

Purpose: The incidence of hepatitis A virus(HAV) infection has markedly decreased in the last 20 years due to industrialization and improvements in the standard of living and hygiene in Korea. The reduction in seroprevalence rates indicates infection potential for young adult population, and a need for vaccinations in high-risk adults and children groups has been suggested. In this study we evaluated the seroprevalence rates and natural infection rates of hepatitis A in children and adolescent to obtain the basic data for vaccination of hepatitis A. Methods: A total of 334 children and adolescent subjects below 20 years old in Kyonggi-do province were examined for HAV antibody and seroprevalence rates in each age group was investigated. In 584 elementary school students residing in Kyonggi-do province, serum samples collected in 1993 and 1996 from the same subjects for investigation of natural seroconversion rates. Method of testing antibody was enzyme immunoassay. Results: 1) The seropositive rate of HAV in 334 subjects aged below 20 years old was 5.4%. According to age, the seropositive rates were 27.3% in infant group, 0.0% in 1~4 year-old group, 0.0% in 5~9 year-old group, 2.9% in 10~14 year-old group and 15.0% in 15~19 year-old group. 2) In the study of 584 elementary school children, only one subject showed seropositive in 1993, and in 1996 three different subjects showed seropositive results(0.5%); the natural seroconversion rate during 3 years was 0.5%. 3) The seroprevalence rates of below 20 year-old subjects reported in previous studies were 63.8% in 1979 and 47.3% in 1989 while the present study showed the rate at 5.4%. Conclusion: Since natural antibody formation is rarely occurring, there is a high risk for apparent hepatitis A infection in adults. Therefore vaccination in high risk groups is essential at present, and in order to reduce the chance for hepatitis A infection in adults, vaccination in children may be needed.

The purpose of this study was to observe the kinematic patterns of hurdling by domestic hurdlers and elite hurdlers from other countries in particular, we studied the hurdling motion and joint angles at the third hurdle in 110-m hurdle races. There were slight differences in the following variables at takeoff and landing: angle of the center of gravity(elite hurdler, $34.14^{\circ}$ domestic hurdler, $24.89^{\circ}$), angle variables the body angle(elite hurdler, $4.27^{\circ}$ domestic hurdler, $6.37^{\circ}$), the angle of trunk inclination(elite hurdler, $3.18^{\circ}$ domestic hurdler, $11.58^{\circ}$), and the hip angle(elite hurdler, $40.1^{\circ}$ domestic hurdler, $43.2^{\circ}$).

The purpose of this study was to obtain basic data on the relationing between smoking, drinking and periodontal pocket formation. There was no nationwide epidemiologic study on periodontal diseases and smoking, drinking in korea. 177 adults aged 20 and older were recruited the study subjects. Data for smoking, drinking and general characteristics were collected by questions. Periodontal pocket formation was measured greater than 3 mm by probing. Sectional arch numbers of periodontal pocket formation by sex, marriage status and drink yes or no were no statististically difference. Sectional arch numbers of periodontal pocket formation by ages were statististically to increase in proportion to age. Sectional arch numbers of periodontal pocket formation by economic status were statististically to increase in proportion to high economic status. Sectional arch numbers of periodontal pocket formation by smoke yes or no were statististically to increase more smokers than non-smokers. According to regression analysis, periodontal pocket formation was influenced by age, economic status and smoke yes or no.

This study investigates the effect of types of usual source of care on medication adherence among the elderly. Using the Korea Health Panel Survey in 2017, this study includes 3,623 elderly people 65 years of age or older taking prescription drugs for treatment of chronic diseases. The type of usual source of care was considered in three aspects: whether having a usual source of care or not, whether having a regular site only or having a regular site and doctor, size of the regular site. The types of usual source of care are heavily associated with medication adherence. Compared to those who have no usual source of care, those who have a regular site only are 1.4 times, and have both regular site and doctor are 1.8 times more likely to comply with the medication guidelines, respectively. The finding shows usual source of care has a positive effect in improving medication adherence of the elderly. The results can provide an evidence for policies for effective management of chronic diseases and efficient use of medical resources.

시장조사 전문기업인 엠브레인트렌드모니터(www.trendmonitor.co.kr)가 2009년에 실시한 한 설문조사결과에서 여름철 냉방기기 사용빈도는 평균 선풍기 76회, 에어컨 24회(총 100회 기준)로 사람들은 더위를 이겨내기 위해 에어컨 보다 선풍기를 많이 사용하는 것으로 나타났다. 선풍기를 보유한 가구는 한 가구당 평균 2.47대의 선풍기를 보유하고 있었으며 전기세부담이 적고 제품가격이 저렴할 뿐만 아니라 이동 및 설치의 간편함 등을 선풍기의 장점으로 꼽았다. 이처럼 국민냉방기기로 굴림하고 있는 선풍기를 보다 안전하고 효과적으로 사용할 수 있는 올바른 사용 및 관리방법을 알아보도록 하자.

This study was performed to investigate the escape of pine wood nematode (PWN), Bursaphelenchus xylophilus, from two vector species (Monochamus alternatus and M. saltuarius) through oviposition and feeding behavior. First, we checked number of PWNs escaped from M. alternatus emerged from three different cases of pine logs. In case A, healthy pine trees were cut into logs and left in pine forest infected with PWN. In case B, healthy pine trees were cut into logs, left in large screen cage, and let them oviposited by M. alternatus emerged from pine trees infested with PWN. In case C, pine trees which were harboring M. alternatus were cut into logs, and PWN was inoculated artificially. The M. alternatus adults emerged from the above three cases of pine logs were checked in the next year to know how many PWN they were harboring in their bodies. The percentages of M. alternatus harboring PWN (18.3 and 15.6%, respectively) and number of nematodes per vector ($5,713.1{\pm}9,248.3$ and $2,034.1{\pm}4,746.8$ PWNs, respectively) in case A and B logs are similar to each other. However, the percentage and the number in case C (38.3% and $20,083.1{\pm}32,188.3$ PWNs) were higher than those of case A and B. Among 52 M. alternatus adults harboring PWN from all the three cases, 20 adults (38.5%) were harboring more than 5,000 PWNs per beetle. And these 20 adults were harboring 97.9% of the total PWNs in 52 adults. Second, we checked the daily escape of PWNs from M. alternatus and M. saltuarius collected at pine forest infested with PWN. The PWN escaped from their vector body for $34.9{\pm}12.4$ days for M. alternatus, and for $23.9{\pm}16.2$ days for M. saltuarius, reaching at peak escape during the 2nd week of emergence of the two vector species. A 44.5 and 47.2% to the total PWNs escaped from vector body within 2 weeks of vector emergence for M. alternatus and M. saltuarius, respectively. The number of PWNs escaped from each vector was $3,570.6{\pm}5,189.2$ and $1,556.2{\pm}1,710.3$ for M. alternatus and M. saltuarius, respectively.
