A cross-sectional epidemiological study using a multistage sampling strategy in slaughter cattle in Mymensingh, Bangladesh was conducted during September 2001 to April 2002 to study distributions and risk factors of specific pulmonary lesions and diseases. The pulmonary lesions and diseases were diagnosed on the basis of macroscopic and microscopic pathological and parasitological findings. The frequency distribution of pulmonary lesions and diseases in slaughter cattle was found to vary among categories of the study variables. The risk factors identified on statistical basis were male cattle and ${\leq}3$ years old cattle and summer in congestion, slightly thin physical condition and summer season in pulmonary emphysema, slightly thin physical condition in parasitic bronchitis as well as female cattle, autumn and rainy seasons in pulmonary hydatidosis. The population impact and etiologic significance of summer season on pulmonary congestion and emphysema was more important than that of adult male cattle. The population impact and etiologic significance of autumn season on pulmonary hydatidosis was more important than that of female cattle during rainy season. Population impact of slightly thin cattle on parasitic bronchitis was poor.

In order to investigate how to maintain normal weight under independent living conditions, twenty female university students were enrolled and asked to complete a questionnaire over a 10- day study period. T-test, Spearman's correlation and multiple regression analysis were applied to describe characteristics of weight maintainers' habits on a daily basis. The results were as follows: They always comsumed small or moderate-sized meals. $2{\sim}3$ co-eaters usually had dinner together at home while not watching TV. They also showed healthy eating behaviors such as no snacking, very little amounts of soft drinks, coffee and alcohol consumption. The always normal weight maintainers, however, were not physically active at all. When being with co-eater(s), they ate larger-sized dinners (${\beta}$ = 0.585, $R^2$= 30.6), and the more co-eaters they had at the dinner table, the greater BMI they got (${\beta}$ = 0.547, $R^2$= 29.9). As a result of this study, encouraging young adult people to exercise on a regular basis is required, even though they seem to succeed in maintaining normal weight without being active physically. Further study is necessary to investigate how co-eaters would influence the amount of food eaten.

The purpose of this study was 1) to identify the effects of lifestyle activities and decision -making related variables (shopping orientations, use of information sources and importance of store attributes) on the outshopping behavior of female consumers in Seoul and satellite cities, and 2) to investigate the differences in the effects of those variables on the outshopping behavior among 4 clothing categories (formal wear, separates, casual wear, underwear). The data were collected via a questionnaires from 508 adult females of ages over 20's living in Seoul and satellite cities around Seoul and were analyzed by factor analysis and discriminant analysis. The results of this study were as follows: 1) Some of the factors of 4 decision-making related variables significantly discriminated the outshoppers and inshoppers. The most influential factors were attitude toward imported products, time-oriented and price-oriented attitude of shopping orientations. 2) There were significant differences in the effects of 4 variables on outshopping behaviors among 4 clothing categories. More factors were effective in discriminating the outshopping behavior for formal wear or separates purchase.

Morphological characteristics and life cycle of Parnara guttata were studied from 2001 to 2002. Egg was hemisphere-shaped in pink. Larva was milky white or yellowish green color with 2.9-30.6 nm body length, depending on their developmental stages from 1 st to 5th instar. Pupa were grayish brown from 23.8 to 25.7 nm length, adults were yellowish brown color and body lengths were 17.4 nm and 16.2 nm and wing expanse lengths were 35.2 nm and 30.6 nm with female and male, respectively. At 25${\pm}$2$^{\circ}C$, each developmental periods was 4.5, 30.2, and 6.9 days with egg, larvae, and pupae, respectively. Also adult longevity were 10.1 for female, average number of egg was 205.5.

The purpose of this study was to investigate consumers' utilization and satisfaction of the current food labeling system, their awareness of the nutrition labeling and its necessity, and their acceptance of the future enforcement of nutrition labeling. Questionnaires were distributed to 500 adult female consumers in Northern area of Kyonggi-do. Out of 402 questionnaires collected 358(89.1%) were analyzed using SAS computer program. The findings of this study were as follow: First, in the aspects of consumers' utilization and satisfaction of the current food labeling system, although they payed much attention to the food labels when they purchased food goods, the degree of their satisfaction in food labels was low. Among items in food labels they payed more attention to the expiration date, the date of production, and the name of manufacturer. However, the current food labeling system does not offer sufficient and reliable informations to consumers. Second, in the awareness of nutrition labeling and its necessity, majority of consumers appeared not to have seen the nutrition labeling in food products either domestic or imported. However, 93% of respondents answered that nutrition labeling is necessary. Third, in terms of the consumers' acceptance of enforcement of nutrition labeling, they were affirmative in bearing the increased costs, and their expectation to the beneficial effects of enforcement of nutrition labeling was stronger than worrying about the disadvantages or side effects of it.

Nasal sounds include nasalized vowels and consonants. Nasal cavity is important for the acoustics of nasal sounds. Evaluating the effects of site-specific nasal obstruction on nasal sound will help us to understand the importance of nasal geometry for the nasal sound and to foretell voice change after nasal surgery This study was designed to analyze the change of nasality and formant characteristics of nasal sound by obstructing different sites around the ostiomeatal unit(OMU). Ten adult male and female volunteers participated. The nasal formants and bandwidths of nasal consonant /n/ were checked in various conditions of nasal obstruction. The nasalance of rabbit, baby, and mama passages were compared in each conditions. Nasalance of all passages decreased when anterior portion of OMU was obstructed. Center frequency of first nasal formant(NF1) of /n/ has decreased in the order of anterior, inferior obstruction. The bandwidth of NF1 decreased in female with anterior obstruction. Anterior portion of OMU is most critical to the change of nasality and acoustics of nasal consonant. When anterior portion of OMU is obstructed, the shift of NF1 to a lower frequency and the narrowing of NF1 bandwidth are the major acoustic changes of nasal consonant /n/.

A syrnpatnc sample of Rana nigrnmaculata sand R plancyi (Anura) from Kwangu, Korea was investigated to clarify their taxonornic status and to estimate the degree of genic variation, genetic relatedness, and reproductive isolation between them, based on electrophoretic analysis, marphometric data, mating call, mating season, and habitat. All the characters measured including morphometric, genetic, behavioral, and ecological suggest that they are distinct species and R nigrnmaculata might have originated from R plancyi (tropical form about three and a half million years ago. An adult female was found to be Fl hybrid between two species The hybrid female possessed fettile eggs and morphologically intermediate to the parental species in head parts, hind limb, and web characters. The differences in mating call, mating behavior, breeding season, and habitat strongly suggest that postmating isolating mechanism is operating, even though very rare hybrid is found.

These studies were carried out to investigate the effects of nonsteroidal ecdysone agonist, tebufenozide on embryonic and postembryonic development of sycamore lace bug, Corythucha ciliata. Tebufenozide exhibited ovicidal activity($LC_{50}=4.0$ ppm). Susceptibility of each instar nymphs to tebufenozide was nearly same($LC_{50}=2.3{\sim}6.0$ ppm). The tebufenozide treatment in the final instar affected the emergence, longevity and fecundity of surving adults significantly. Tebufenozide applied at high concentration (10 ppm) to younger adults delayed prioviposition period, and decreased adult longevity, the number of eggs laid per female and hatchability. The treatment also inhibited the ovarian development of the female adults.

Essential oils of three plants (caraway oil, hyssop oil and lime oil) were screened for repellency against Tetranychus urticae female adults in the lab condition. Among them, caraway oil (Carum carvi) showed $92.2\%$ repellency against female adults at 1,000 ppm concentration. Through the constituent analysis using GC and GC/MS, we confirmed that the two main constituents were carvone $(73.3\%)$ and limonene (26.7). Limonene showed 87.8 and $83.1\%$ repellency against adult females at 1,000 and 100 ppm concentrations, respectively.

In a cross-sectional abattoir survey of bovine pulmonary diseases in Mymensingh, during September 2001 to April 2002, subclinical Dictyocaulus viviparous infection was found in mesoendemic level in Bangladeshi adult zebu cattle. The number of mature lung worms varied from $1{\sim}18$ in individual lungs. One to five mature lung worms were most frequent (74.2%) followed by 6 to 10(19.3%) and $11{\sim}18$ (6.5%). Of the total 123 mature worms collected from 31 lungs, there were 50 (40.7%) male and 73 (59.3%) female worms. The female lungworms (mean length 14.41mm) were significantly (P<0.01) larger than the male lungworms (mean length 11.28mm). The number of hydatid cysts varied from $1{\sim}80$ in individual lungs. One to five ($1{\sim}5$) cysts were recorded most commonly (76.0%) followed by $11{\sim}80$ (20.0%) and $6{\sim}10$ (4%). The size (diameter) of the hydatid cysts ranged from $2{\sim}12cm$. Of the total 203 hydatid cysts collected from 31 lungs 45 (22.2%) cysts were fertile and 158 (77.8%) cyst were sterile.
