Lung cancer is the most common fatal malignant lesion in both sexes. Detection of the solitary pulmonary nodule is important because surgical series up to a third of solitary pulmonary nodules are bronchogenic carcinoma. Bronchioloalveolar cell carcinoma is a rare primary lung cancer and surgery is treatment of choice in brochioloalveolar cell carcinoma. We experinced a case of bronchioloalveolar cell carcinoma in solitary pulmonary nodule with cavitary lesion in chest CT scan, which is an uncommon finding in brochioloalveolar cell carcinoma.

This is an exploratory study to describe drinking patterns and problem drinking and alcohol-related problem in college students. The major purpose of this study is to describe the prevalence of drinking styles, the quantity of alcohol getting drunken and the describe the frequency of drunkenness in the previous 12months prior to the survey, and to examine the patterns of how various drinking behaviors are different by drinking style. We used the scale for measuring problem drinking NAST(1), AUDIT, indicated that males drank more and more and more frequently, and had episodes of drunkenness and more accepting of drinking than females, the amount of alcohol becoming intoxicated, the frequency and quantity of alcohol consumed in the month, and the frequency of intoxicated were significantly different by drinking styles in both sexes. A problem drinking rate, danger drinker 49.3% dependence drinker 3.5% in ADULT and alcohol dependency 9.7% in NAST(1) It will be necessary to discuss about adequate policy and eucation protrams to be able to curb collegiate's alcohol abuse.

Mating behaviour of the gammarid amphipod, Hyale rubra, was observed. H. rubra displayed precopulatory mate guarding: males clasped females with their gnathopods during copulation, forming a pair. Males also participated in embryo care during the incubation period. The population was small, and the sex ratio was almost equal. Energy allocation for mating effort and parental effort in the two sexes appear to be almost equal. The mating system was sequentially polygamous (or promiscuous) and there was conspicuous sexual dimorphism in the size of the gnathopod, which was used for mate guarding. However, there appears to be relatively weak sexual competition for mating opportunities despite conspicuous sexual dimorphism. H. rubra did not display territorial competition or external fertilization. Nevertheless, the male provided paternal care. Since H. rubra inhabit tide pools and live on algae, the polygamous mating system of the species can be explained by the polygyny threshold model. The evolution of mate guarding and parental care may have been favored by the species' low population density and harsh environments, an interpretation consistent with the optimality model.

The central goal of this study is to find out of the boy students in middle school the attitude towards house life and house-hold affairs of the boys； and explain what will be of their attitude after they have got Home Economics education. For the purpose of this study, 138 questionairs were distributed to the boy students who had educated Home Economics in school and the ones who had not. The results were as follows； 1. The educated group has higher score in ability of house-hold making than the other group. 2. The educated students responed affirmatively to the utility and necessity of Home Economics education. 3. The teachers who have taught Home Economics to male students have opinions that the students needed Home Economics education to increase the ability of doing house-hold work. Accordingly, Home Economics education should be taught to both sexes in order to have good quality of life, and requires more hours to study as well.

Eighty children, aged from 2 years 8 months to 5 years 1 month old, were examined to study the relationship between the preschool children's response at dental visit and the influencing factors. The results were as follows: 1, There was no significant relationship between the sexes and the children's response. 2. Children who experienced the painful dental treatment demonstrated significantly more negative dental response. 3. Children who stowed negative dental behavior at last dental visit demonstrated significantly more negative dental response. 4. Children of mothers with high anxiety scores demonstrated significantly more negative dental response. 5, Children who were unpleasant at hospitaization demonstrated significantly more negative dental response. 6. Children who thought they had dental problems demonstrated significantly the most negative dental response. 7. Children who abhorred the medical treatment demonstrated significantly more negative dental response.

This study primary aim is to investigate students' responses to experimental results which conflict with their preconceptions regarding electrical circuits. Eighty-eight students of both sexes were randomly selected from a science high school in Korea. They were questioned about their preconceptions regarding an electric circuit, and sixty-eight students with relevant misconceptions were selected. These students were presented with experimental results obtained by some other experimenter, and asked to interpret these results. The second aim of this study is to explore how students' responses vary according to the type of inquiry-skills required to obtain the result. To do this, two type of experimental results were developed: one obtained by observation and the other obtained by controlling variables. We found that many students doubted results for the simple reason that they conflicted with their preconceptions. They rejected results by mentioning other factors which could have affected the result, or simply by reiterating their preconceptions. This behaviour varied considerably by inquiry-skill type. 41% of students rejected conflictual result obtained by observation, but only 6% of students rejected results obtained by controlling variables.

The formal constructions of deconstructive architecture in the contemporary fashion expressed as intertexruality, difference and trace and the working of DIS and DE, and intertextuality in deconstructive has manifested itself as the intertextuality of material, hybridization of items, the blending of modes and the bi-sexuality of sexes. And the difference and trace found in fashion are fantastic and playful and come to exist as historicity. DIS and DE in fashion shows the retrogression of gravity through non-structural silhouette. Their disentring expression emerged as construction through mixture and repetition as well as overlapping of planes or spaces. And their disjuctive representation appeared in the form of mutual juxtaposition and substitution with the double-side of formal construction in fuctional terms.

Incidence/mortality of liver cancer follow logistic curves because there is a limit reflecting the prevalence of hepatitis virus carriers in the cohort. The author fitted logistic curves to incidence/mortality data covering the nine five-year cohorts born in 1911-1955 of both sexes. Goodness-of-fit of logistic curves was sufficiently precise to be used for future predictions. Younger cohorts born in 1936 or later were predicted to show constant decline in incidence/mortality in the future. The male cohort born in 1931-35 showed an elevated incidence/mortality of liver cancer early in their lives supporting the previous claim that this particular cohort had suffered massive HCV infection due to nation-wide drug abuse in the 1950s. Declining case-fatality observed in younger cohorts suggested improved treatment of liver cancer. This study demonstrated that incidence/mortality of liver cancer follow logistic curves and fitted logistic formulae can be used for future prediction. Given the predicted decline of incidence/mortality in younger cohorts, liver cancer is likely to be lost to history in the not-so-distant future.
