Laboratory Evaluation of the Lethal Efficacy of an Insect Growth Regulator, Pyriproxyfen against Anopheles sinensis (Diptera, Culicidae) Larvae

이원자,이동규 한국곤충학회 2005 Entomological Research Vol.35 No.1

The granular formulation of 0.5% pyriproxyfen is a mosquito insect growthregulator larvicide. It was evaluated for residual activity for killing and/or emergence inhibitionagainst 3rd stage larvae of Anopheles sinensis in the laboratory. Mortality rates ranged from 60.9% to 79.7% at 0.01, 0.05 and 0.1 mg/L of water during the first seven days. Except for the lowest concentration (0.01 mg/L) mortality rates were greater than 80% from day 8 through 28. Mortality rates for 0.01 mg/L concentrations were 70.4% from days 8-14, and thereafter exceeded 80% through day 28. The residual activity gradually increased post-treatment since the granular formulation of pyriproxyfen has a gradual solubility and increases concentration of active ingredient over time. The mortality rates of An. sinensis larvae and pupae eventually reached 100% for the three (0.01, 0.05, 0.1 mg/L) concentrations.

This study investigated the relation between seasonal variation of total clothing weight, room, outdoor temperature and basal metabolic rate in man. The basal metabolic rate and total clothing weight, room temperature was determined seasonal for a period of two years and grouped four seasons. Subjects (adults volunteers) who live in seoul and mokpo were compose 120 subjects The results were obtained as follows. Seasonal outdoor temperature was difference of seoul and. mokpo. But room temperature in apartments was a little difference than private house. Total-clothing weight is showed seasonal variations at the seoul, private house than at the mokpo, apartment.. The basal metabolic rate is suggested there in gender difference in the basal metabolic rate (P〈.001). The basal metabolic rate increased gradually with the peak of winter sespectively and deceased again todward summer. The difference of between basal metabolic rate in summer and winter was significant room temperature, of seoul and private house, and light total clothing weight

李元子 건국대학교 1976 學術誌 Vol.20 No.2

The writer may be permitted to present following report found from the comprehensive reality survey on the diaper and diaper cover, which has been conducted through the households in downtown Seoul and its surburbs. 1.Diaper a. The average number of diaper required per infant was found 20.4 pieces and the critical rate against the significant on the month and birth sequences can be allowed in the limit of less than 1%. b. The material was mostly of cotton-shitting (86.0%) and the diaper was mostly of square shape (76.0%) 2.Diaper Cover a. Of the surveyed households, 73.5% of them were accostomed to use the cover, largely when the infants were fallen asleep or going out of their home. b. The average number of cover used per infant was 1.2 pieces and there could be found no significant differences in the ages or birth sequences. The most largely used shape wart of contour diaper sahpe and gripper type (82.3%) and some households were using vinyl covered on the diaper for the substitute (32.5%) As indicated in the above findings, most of the infants are cared in the conventional way pecurior to Korea from the past, and resultingly no sanitary considerations were applied in accordance with the infant's growing states, daily conditions, or seasonal clange. For further study on the tempeature, humidity, and discomfort inside the cover five types of diaper cover and two types of diaper have been experimented on the infant separately in summer and in winter, and followings were observes. a. In summer, wearing any kind of cover causes increases of temperature, humidity, and discomfort in the elapse of time and these increases were getting faster in the was rather slow in the above increases however was faster than the diaper, but it was almost same with the diaper covered with vinyl. b. Likewise in winter, the elapse of time causes proportional increases of temperature, humidity, and discomfort. However, the materials did not play much in the increase of temperature whereas humidity caused by the different materials caused increase of discomfort. In conclusion, using the cover in summer should rather be prohibited because the elapse of time causes increases of humidity, temperature and discomfort regardless of the materia, while in winter the cotton one or with sponge one with the cotton fabric or the diaper covered with vinyl are to be recommended for their good ventilation. However, in all the cases wearing for the exceedingly longer time the diaper with or without the cover is not disirable.

This study is intended to examine the current situation and the problems of the “worksheets, regarding various factors that exert influences onto the quality-risk management, which is one of the most significant factors specifying an apparel product. This paper advances according to the following sequences: 1. Literature survey 2. Field research on actual “apparel vendors” and production factories 3. Investigating the requirements relating to the worksheet 4. Developing standard format of the worksheet 5. Effectiveness analysis on the standard worksheet 6. Proposal of an intelligent model applying standard worksheet system. This study is performed with the following research methods; those are questionnaire surveys, statistical analysis, interviews, collecting & analyzing worksheets, product sample quality experiment, functional analysis of the system, and materialization of the prototype system. The significance of this research is that it suggests the possible effective use of worksheet, which reflects the customers' needs in term of the product quality, at the stage of the product planning process. Despite its importance, the current work structure does not visibly reflect these components. Therefore, with the result of this research, it is considered that the worksheet systems will meet more useful improvements in risk management process. The limitations of this research are as follows. Although it is evident that the standard worksheets bring effective results in quality improvements of products, considerations must be made onto some additional payoffs arising from the additional cost of necessary labor forces with expert knowledge and cost of the effort and time inputting correct information for running the system.

서울·연변간 착의실태 조사분석 : 착의량을 중심으로 Focusing on the clothing weight

이원자,오순 한국의류학회 1999 한국의류학회지 Vol.23 No.7

In order to find out the influences upon not only the thermal resistance of human body but also the clothing action and the clothing weight, which are caused by the differences in the thermal living conditions by using air conditioner and so on, to adapt themselves to the changes of their residential environment according to the changes of seasons, we investigated the clothing practices upon the male and female students in Seoul and Korean male and female students in Yanbian who are estimated to have different thermal living conditions in spite that they are same folk as well as living in the same age. 1. The total clothing weight of body surface erea was increased in order of summer, autumn, spring and winter seasons and by seasons, the changes of the clothing weight were found in both areas. In Seoul, the changes of upper outwear clothing weight were found on both sexes but in Yanbian, the changes of underwear weight were found on both sexes. And the underwear weight of both sexes in Seoul was lighter than that of both sexes in Yanbian. 2. Those in Seoul tended to fell colder in winter and hotter in summer than those in Yanbian on account that the formers are more sensitive of thermal conditions than the latters. 3. Comparing clo-value calculated by the fomula of 稻垣 with the Winslow's clo-value, those in Yanbian had higher thermal resistance than those in Seoul. Consequently, those in Seoul adapted themselves to the seasons by controling the upper outwear weight but those in Yanbian did it with underwear weight. The male and female students in Seoul, tended to feel colder in winter and hotter in summer than those in Yanbian because the thermal sense of the former is more sensitive than that of the latter.

이원자,이형우,신이현,양영철,김남렬,홍성태,이종수 한국곤충학회 2000 Entomological Research Vol.30 No.2

최근 삼일열말라리아가 재유행하고 있는 경기도 북부지역에서 채집한 얼룩날개모기속(Anopheles)모기의 삼일열원충 감염 여부를 중합효소연쇄반응(Polymerase chain reaction)법으로 확인하여 매개모기의 종을 재확인하고 분포 양상을 조사하였다. 1996년 8월29일부터 9월 19일까지 철원군 소재 군부대 GOP와 대마리, 연천군의 석장리, 원당리, 동중리, 현가리, 파주시의 장파리, 마정리, 법원리, 백련리, 조산리, 파주리 그리고 동두천시의 생연동에서 드라이아이스법으로 19시부터 다음날 아침 07시까지 모기를 채집하였다. 채집된 5,615마리의 Anopheles속 모기를 동정한 결과 An. sinensis가 4,866마리 (86.7%), An. yatsusiroensis가 561마리 (9.9%), An. pullus가 112마리 (1.9%), An. sineroides가 58마리 (1.0%), An. lesteri가 12마리 (0.2%), An. koreicus가 6마리 (0.1%)였다. 채집지별로 Anopheles 속 모기의 genomic DNA를 분리하였고, 삼일열원충 특이 유전자인 circumsporozoite protein유전자를 두쌍의 primer를 이용하여 nested-PCR법으로 증폭하였다. 그 결과 파주시의 백련리와 장파리에서 채집된 An. sinensis에서 약 870 bp크기의 PCR 증폭산물을 확인할 수 있었다. 이 PCR 증폭산물을 Pv210과 Pv247에 대한 oligonucleotideprobe를 사용하여 DNA hybridization한 결과, 두 지역에서 채집된 모기들은 Plasmodium vivax Pv210 type에 감염된 것으로 밝혀졌다. The vivax malaria was re-emerged in northern part of Kyonggi-do, rescently. Anopheline mosquitoes were analyzed with polymerase chain reactions to determine what kind of mosquito is the main vector for malaria transmission. The Anophetine mosquitoes were collected from 29th Aug. to 19th Sep., 1996, in epidemic areas. The areas were GOP of XX corps and Taema-ri in Chorwon-gun, Seokjang-ri, Wondang-ri, Tongiung-ri and Hyunga-ri in Yonchon-gun, Changpa-ri, Majeong-ri, Popwon-ri, Paekryun-ri, Chosan-ri and Paju-ri in Paju-shi, Saengyon-dong in Tongduchon-shi. Mosquitoes were collected by dry ice method from 19:00 to 07:00 on next morning. Total 5,615 Anophetine mosquitoes were collected and identified into species based on taxonomic criteria. As a results of classification, 4,866 An. sinensis (86.7%), 561 An. yatsusiroensis (9.9%), 112 An. pullus (1.9%), 58 An. sineroides (1.0%), 12 An. lesteri (0.2%), and 6 An. koreicux (0.1%) were identified. Anophetine mosquito DNA was extracted and then amplified the circumsporozoite protein gene, which is the specific gene of Plasmodium vivax, with nested-PCR method. PCR products (about 870 bp) were observed with DNA samples of mosquitoes collected in Changpa-ri and Paekryun-ri. As the results of DNA hybridization, the amplified PCR products belonged to Plasmodium vivax Pv210 type.
