  • In the cities nowadays, the dwelling conditions of Cackroach are provided by use of various kinds of construction material, installation of heating and cooling facilities that maintain moderate temperature, filthy sanitation, and lack of knowledge about insect as mechanical Vector. Cakroach is infectious disease Vector, and it proves to be of much importance in the public health. Considering such importance, the author has surveyed the distribution of Cackroach in the housing areas of Seoul City from May 1969 to the end of August 1969, and has come to the following conclusion: 1. House dwelling Cackroach collected in the City of Seoul are of two species, i. e. Blatella Germanica Linneaus and Periplaneta Japonica Karny. 2. Most of cackroach collected in Seoul are Blatella Germanica Linneaus and they are distributed in whole area of Seoul while that of Periplaneta Japonica Karny is distributed only in the limited area. 3. Dwelling places of Blatella Germanica Lineaus are in grog shop, Korean food restaurants, bakery shops, and patient rooms in hospitals. Many of them are found in tile kitchens and dining rooms of restaurants, and tearooms. They live in groups at older houses with much crack, warm and humid places. 4. For method of collection, the hand collection was the most effective. In trap collection during the day time, when the trap is placed at the narrow corners off the ground after confirming the dwelling places of cackroach, the match trap was more effective than the flask trap in collecting. In case of collecting during the night time, the flask trap was much more effective method than the match trap.

  • The first aim of the study was to compare selected meat quality parameters in porkers without the gene $RYR1^T$ (ryanodine receptor gene). These were porkers slaughtered at 100 to 115 kg and 116 to 130 kg live weight. The second aim of the study was to determine the occurrence frequency of standard-quality meat (red, firm, nonexudative [RFN]) and the occurence frequency of defective meat (pale, soft, exudative [PSE] and acid, soft, exudative [ASE]). The analysis was conducted on the longissimus lumborum muscle in 114 crossbred porkers. The porkers were a cross of Camborough 22 sows and boars from lines 337PIC (Pig Improvement Company), Norsvin Landrace and Pietrain. All of the animals were provided with identical environmental and nutritional conditions. The average weight of the slaughtered animals in the light and heavy groups was 110 kg and 122 kg, respectively. Both groups had the same average post-slaughter meatiness (56.5%). A statistical analysis of selected meat-quality parameters did not show any significant differences between the weight groups. On the other hand, the classification based on carcass quality showed an occurence frequency of defective meat in heavier crossbred porkers (116 to 130 kg) that was three times higher than in those cross bred animals which weighed 100 to 115 kg when slaughtered. In porkers without the gene $RYR1^T$, the defective meat types PSE and ASE occurred with a frequency of 17.54%.

  • 본 연구는 Apocyclops royi를 양식에서 초기 먹이생물로 적용시키기 위해 이들의 대량배양을 위한 수온과 염분의 최적범위 및 최적 성장을 위한 먹이를 구명하고자 실시되었다. A. royi 성체 암컷의 총 nauplius 생산력은 수온 $32^{\circ}C$에서 188 개체로 가장 높게 나타났고 성체 암컷 당 일간 nauplius 생산수도 총 생산수와 같은 경향을 보여 $32^{\circ}C$에서 13.4개체로 가장 높게 나타났다. Nauplius 부화 후 최초 포란할 때까지 발달 기간은 $32^{\circ}C$가 7.2일로 가장 빠른 발달을 보였으며 수온이 감소할수록 발달기간이 느린 경향을 보였다. A. royi 성체 암컷의 총 nauplius 생산력은 염분 10 ppt에서 169 개체로 가장 높게 나타났고 성체 암컷 당 일일 평균 nauplius 생산수는 10 ppt가 9 개체로 가장 높게 나타났다. Nauplius 부화 후 최초 포란할 때까지 발달 기간은 10 ppt와 15 ppt이 각각 7.1일, 7.7일로 빠른 발달을 보였으며 염분이 높을수록 발달기간이 길어지는 경향을 보였다. A. royi 성체 암컷의 총 nauplius 생산력은 I. galbana와 T. suecica 공급구에서 각각 142, 127 개체로 가장 높게 나타났고, 성체 암컷 당 일일 평균 nauplius 생산수는 I. galbana 공급구가 8.2개체로 가장 높게 나타났다. Nauplius 단계에서 copepodid 단계까지의 발달 기간은 I. galbana, T. suecica, P. tricornutum 공급구가 각각 3.4, 3.6, 3.7일로 담수산 농축 Chlorella와 빵 효모 공급구보다 빠른 발달을 보였다. 결론적으로, cyclopoid 요각류인 A. royi는 대량배양의 잠재성이 있으며 최적 대량배양을 위해서는 수온 $32^{\circ}C$, 염분 10 ppt에서 먹이로 I. galbana를 공급하여야 할 것으로 판단된다.

  • Objectives : The present study investigated the anti-obese and blood flow improvement activities of aqueous extracts of ginseng berry (GBe) on the mild diabetic obese mice as compared with metformin. Methods : After end of 56 days of continuous oral administrations of GBe 150, 100 and 50 mg/kg, or metformin 250 mg/kg, anti-obese and blood flow improvement effects - the changes of body weights, body and abdominal fat density by in live dual-energy x-ray absorptionmetry (DEXA), tail bleeding time, prothrombin time (PT), activated partial thromboplastin time (aPTT), serum total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL) and high density lipoprotein (HDL) levels, aorta and serum cyclic guanosine monophosphate (cGMP), nitric oxide (NO) and endothelin (ET)-1 levels, aorta phosphorylated PI3K (pPI3K), phosphorylated Akt (pAkt) and phosphorylated p38 MAPK (pp38 MAPK) levels were systemically analyzed. In addition, aorta vascular dilation and constriction related gene mRNA expressions - PI3K, Akt, eNOS, p38 MAPK and ET-1 were also analyzed by realtime RT-PCR. Results : The obesity and related blood flow impairment, induced by 84 days of continuous HFD supply, were significantly inhibited by 56 days of continuous oral treatment of GBe 150, 100 and 50mg/kg, dose-dependently, and they also dramatically normalized the changes of the aorta vascular dilation and constriction related gene mRNA expressions, also dose-dependently. Especially, GBe 150 mg/kg constantly showed favorable inhibitory activities against type II diabetes related obesity and vascular disorders through PI3K/Akt pathway and p38 MAPK mediated cGMP, NO and ET-1 expression modulatory activities, as comparable to those of metformin 250 mg/kg in HFD mice. Conclusion : By assessing the key parameters for anti-obese and blood flow improvement activities on the HFD-induced mild diabetic obese mice, the present work demonstrated that GBe 150, 100 and 50 mg/kg showed favorable anti-obese and blood flow improvement effects in HFD-induced type II diabetic mice, through PI3K/Akt pathway and p38 MAPK mediated cGMP, NO and ET-1 expression modulatory activities.

  • Along with olive flounder(Paralichthys olivaceus), black rockfish(Sebastes schlegeli) is another very popular maricultured species in Korea. As there is many difficulties in handlling live fish for aquaculturist, use of suitable anesthesia for proper handling of fish is very important in the field. In this view, the effect of $AQUI-S^{\circledR}$ has analysed for its use in the field. $AQUI-S^{\circledR}$, contains 50% isoeugenol, is a new anesthics for fish and zero-withdraw time required since it was approved as a safe additives of food. In the present study, black rockfish adult exhibted sedation effect from 5 ppm at $10^{\circ}C\;and\;15^{\circ}C$, and 7.5 ppm at $20^{\circ}C$, on the other hand, anesthesia was at least required 7.5 ppm at $10^{\circ}C\;and\;15^{\circ}C$, and 10 ppm at $20^{\circ}C$. The fish was recovered from sedation and anesthesia after approximately 5 and 10 minutes, respectively. In case of black rockfish fry, sedation was recorded from 2.5 ppm at $20^{\circ}C$, and 5 ppm at $15^{\circ}C\;and\;20^{\circ}C$. The least concentraion of anesthesia was 2.5 ppm at $10^{\circ}C$, 7.5 ppm at $15^{\circ}C$, and 5 ppm at $20^{\circ}C$. The acute toxic test showed that black rockfish adult and nv showed mortality above 12.5 and 15 ppm concentration of $AQUI-S^{\circledR}$, respectivly. In sum, $AQUI-S^{\circledR}$ is considered as useful anesthetic drug for sedation and anesthesia of black rockfish, it is highly availbale to be prevented from a varity of stress.

  • This study was conducted to provide basic data for development of public information program and public policy which could prevent the medicine abuse in Korea, examining the level of knowledge of medicine and its related factors. Data were collected from the 2,011 residents who live in mtropolitan cities, large-sized cities, small and medium cities, and small towns The results of this study are summarized as follows. 1) In case of purchasing of medicines in pharmacy, 67.3% of the respondents chose the medicines through recommendations of the professionals such as pharmacists and doctors, while 32.7% of the respondents chose the medicine through self-judgement, advertizing, or recommendation of relative. 2) 64.7% of the respondents obtained the information on medicines through TV. It appeared to be higher in the groups of female of the twenties, the unmarred, a brother and sister threesome, highschool graduates, housewives, residents in small and medium cities, atheists, and the middle class, displaying the significant difference from the other groups. 3) 40.5% of the respondents recognized the side effect of the medicine when they took the medicine, while 34.4% did not recognize it. The rate of experience in the side effect was 39.7%. The informations on the medicine abuse and the risk of addiction were obtained through broadcast media (47.9%), publications (12.1%), and health professionals (11.6%). 4) 81.1% of the respondents experienced taking of the fatigue relieving medicine. The experience in taking of the fatigue relieving medicine appeared to be higher in the groups of the forties. the married. a brother and sister threesome. highschool graduates. persons engaging in farming, livestock raising, and forestry, the residents in small towns, and Christians. Each group displayed the significant difference from the other groups. 5) According to the level of knowledge of medicines, the respondents marked average 11.7 ± 3.76 points on the base of 24 points. It appeared to be higher in the groups of female of the twenties, a brother and sister foursome, college graduates, teachers, Catholics, and the middle class, displays the significant difference from the other groups. 6) According to the experience in taking of health medicine and health food, 81.1% of respondents had the experience in taking ‘the fatigue relieving medicine’; 72.4% ‘carrot or vegetable juice’; 69.5% ‘ginseng’; 63.0% ‘mushroom’; 42.5% ‘dog meat’; 38.0% ‘aloe’; 36.4 ‘deer antlers’; 11.4% ‘snake’; 2.0% ‘the penis of a fur seal’. 7) The factors influencing the level of knowledge of medicine include experiences in taking of the tonic, the fatigue relieving medicine, and the nutritive medicine, economic status, the number of brothers and sisters, education level, marital status, father's education level, and age. The factors influencing the experience in side effect of medicine are experiences in taking of the fatigue relieving medicine, the nutritive medicine, and the tonic, sex, age, education level, father's education level, marital status, economic status, religion, and the number of brothers and sisters. In conclusion, it is estimated that the level of knowledge of medicines is significantly low in Korea. Especially, it is found out that workmen, students, the upper class, the class of low education level, and persons engaging in farming, livestock raising, and forestry neglect importance of knowledge of medicine. Therefore, it is necessary for public authority, associations related, and health professionals to develop programs for public information and education to help people obtain basic knowledge of medicine.

  • This study aims at examining perception of body weight control and lifestyles and food habits of under-weight, normal-weight and over-weight female college students. The data analysis were conducted by a body fat analyzer and questionnaires. The subjects were 368 female college students divided into three groups: the under-weight(UW), the normal-weight(NW), and the over-weight(OW), according to the guidelines of the Korean Society for the Study of Obesity(2000). Among the subjects, 18.2% were under-weight, 63.6% normal-weight, and 18.2% over-weight. Mean of body weights were 45.4kg, 53.3kg, and 63.7kg, and BMIs were $17.5kg/m^2$, $20.5kg/m^2$ and $24.6kg/m^2$ in the UW, NW, and OW groups, respectively. 'Self assessment of body weight' was significant at the level of p<0.001 according to the Obesity Index. Of the UW group, 41.8% considered their weight to be normal and 4.5% believed they are over-weight. In the NW group, 43.2% thought they are over-weight, 1.5% believed they are under-weight. 57.1 % of the UW group and 98.6% of the NW group had ever tried to reduce their weight. Their 'exercise frequency and exercise time' were not significant by the 01. 'Regularity in the daily life' of the subjects was significant at the level of p<0.05. 43.3 % of the OW group answered that they don't live regular daily lives. 'Sleeping time' of the subjects was significant at the level of p<0.05 by the 01. 41.8% of the OW group reported that they sleep 'between 7 and 8 hours a day' which was the highest rate among the three groups. 'Frequency of meals per day' was not significant by the OI. 'The speed of eating meals' was significant at p<0.01, 23.9% of the UW group, 31.2% of NW group, and 38.8% of OW group reported that they have meals 'in a very fast speed'. Concludingly, most of female college students conceive themselves as having inappropriate body image, which means that they need to be given additional education about nutrition and diet.

  • Amphiprion melanopus의 난발생과 자치어의 형태학적 발달에 대한 기초 조사와 함께, 먹이생물과 갑상선호르몬이 자치어의 성장과 체색에 미치는 영향을 조사하였다. 수정 후, 부화까지 총 168시간이 소요되었다. 갓 부화 자어의 크기는 평균 $3.5{\pm}0.3$ mm 으며, 대부분의 자어는 부화 후 경과일 수에 따라 체색 변화(변태)를 나타내었다; DAH(days afterhatching) 10: 체색 흑화, DAH 15~20: 3개의 흰 줄무늬 출현, DAH 30: 등과 꼬리지느러미의 흰 줄무늬가 사라지기 시작,DAH 90: 체색 주황색; 성어: 체색은 진한 계피색이며 머리에만 흰 줄무늬 남음. Artemia와 T. japonicus를 함께 공급한실험구의 성장은 Artemia만 공급한 실험구보다 빨랐다. T. japonicus 만을 공급한 실험구의 지느러미 체색은 진하고 선명한 주황색이었다. 갑상선호르몬을 처리한 4 ppm구의 성장이 다른 실험구(0, 2, 6 ppm)보다 빨랐고 6 ppm구가 가장 느렸다. 본 연구의 결과, 주요 먹이생물로 알려져 있는 Artemia와 함께 T. japonicus를 공급함으로써 A. melanopus의 성장과체색을 개선시킬 수 있었고, 갑상선호르몬 또한 변태 및 체색 형성에 직접적으로 관여할 것으로 사료된다.
