This study was carried out to identify the Important modifiable risk factors for reduced bone mass and to construct prediction model which can classify women with either low or high bone mass. Through the literature review, individual characteristics such as age, body weight, height, education level, family history, age of menarche, postmenopausal period, gravity, parity, menopausal status, and breast feeding period were identified and factors of life style such as past milk consumption, past physical activity, present daily activity, present calcium intake, alcohol intake, cigarette smoking, coffee consumption were identified as influencing factors of reduced bone mass in women. Four hundred and eighty women aged between 28 and 76 who had given measurement bone mineral density by dual energy x-ray absortiometry in lumbar vertebrae and femur from July to October, 1997 at 4 general hospitals in Seoul and Pusan were selected for this study. Women were excluded if they had a history of any chronic illness such as rheumatoid arthritis, diabetes mellitus, hyperthroidism, & gastrointestinal disorder and any medication such as calcium supplements, calcitonin, estrogen, thyroxine, antacids, & corticosteroids known affect bone. As a result of these exclusion criteria, four hundred and seventeen women were used for analysis. Multiple logistic regression model was developed for estimating the likelihood of the presence or absence of reduced bone mass. A SAS procedure was used to estimate risk factor coefficient. The results are as follows For lumbar spine, the variables significant were age, body weight, menopause status, daily activity, past milk consumption, and past physical activity(p<0.01), while for femoral Ward's triangle, age, body weight, level of education, past milk consumption, past physical activity(p<0.001). Past physical activity, present daily activity and past milk consumption are the most powerful modifiable predictors in vertebrae and femur among the predictors. When the model performance was evaluated by comparing the observed outcome with predicted outcome, the model correctly identified 74.1% of persons with reduced bone mass and 84.5% of persons with normal bone mass in the lumbar vertebrae and 82.9% of persons with reduced bone mass and 75.0% of persons with normal bone mass in the femoral Ward's triangle. On the basis of these results, a number of recommendations for the management of reduced bone mass may be made : First, those woman who are classified as high risk group of the reduced bone mass in the prediction model should examine the bone mineral density to further examine the usefulness of this model. Second, the optimal amount of milk consumption and a regular weight bearing exercise in childhood, adolescence, and early adult should be ensured.

Ascariasis symptoms penetrated into biliary tract are reported to be found much more in Korea than in foreign countries. And the present writer believes there are also many cases of biliary tract symptoms that are actually experienced but that are not reported. As a result of experiencing and nursing twenty cases of ascariasis symptoms of biliary tract, the present writer has got several conclusions, and reports them together with reference to sundry records. (1) The penetrating rate of ascariasis in male versus female was 1 to 1.5. Consequently the rate of female was higher than that of male. The highest age of the case was 67, the lowest 19, and the average age was 45.2. (2) As to symptoms, right upper quadrant abdomen pain and fat diet intolerance were the largest in number. By laboratory findings there were depressive pain on right upper quadrant abdomen in all the cases. (3) As to the location of ascariasis, choledochus occupied the largest part, and the longer illness history was, the more cases coexisting with calculus were found. (4) As to operative method, cholecystectomy and choledochotomy weres the largest in number, and choledochotomy T-tube was inserted in all cases. As to complication after operation, there were operative wound infection, excoriation through bile juice issue, etc. There were three cases of re-penetration of ascariasis and only one case of reoperation.

The elementary school classroom is a space where children spend a long time during the day, during the six years of childhood, in which children are emotionally sensitive and emotionally important. Therefore, it is necessary to create a classroom that can develop emotions considering the developmental characteristics of children. However, the elementary school classroom in Korea has less change in the classroom envir- onment than in the rapidly changing curriculum, and classrooms and furniture considering emotional development are hard to find. Therefore, this study suggests the necessity of improvement for classroom furniture of elementary school, presents problem and consideration condition of present classroom furniture by analyzing the present condition of elementary school classroom in Korea and child development characteristic of school age, and proposes the improvement direction through analyzing domestic and foreign classroom furniture products. To do this, we checked the physical and developmental characteristics of children ages 8 to 13, confirmed the use of the classroom furniture in 10 schools located in Seoul, Gye- onggi and Incheon, analyzed the problems of these furniture, compared and analyzed the shape, material, and color of the products of 32 domestic companies teaching tools manufacturers focusing on desks, chairs, lockers, and teaching aid box that are commonly used in classrooms. Through this, this study provided basic data for the selection of ideal classroom furniture in the future.

Background: Classical Hodgkin's lymphoma (cHL) is a B-cell lymphoid neoplasm characterized by a distinctive biological behavior with potentially curable disease characteristics. It is an uncommon hematological malignancy which primarily affects younger individuals. The rationale of this study was to determine its clinico-hematological profile along with stage stratification in Pakistani patients. Materials and Methods: In this descriptive study, adult patients with Hodgkin's lymphoma were enrolled from January 2010 to December 2014. Results: Sixty two histopathologically confirmed cases of cHL were identified. There were 42 males and 20 females, with a male to female ratio of 2: 1. The mean age was $29.7{\pm}13.8$ years with the median age of 30 years. B symptoms were present in 72.5% of patients. Histopathologically, the mixed cellularity type constituted 62.9% of cases, followed by nodular sclerosis in 25.8%, lymphocyte predominant in 9.6% and lymphocyte depleted in 1.6%. Stages I and II were present in 43.5% of patients at disease presentation, with 56.4% in stages III and IV. Conclusions: Our analysis shows that clinico-pathological features of Hodgkin's lymphoma in Pakistan are comparable to published data. Mixed cellularity is the commonest histological variant and advanced stage at presentation are common findings in our patients.

The purpose of the present study was to address whether the in vivo noradrenergic neural activities in the locus coeruleus are involved in the regulation of blood pressure. Two groups of the animals were prepared, 1) SHR and 2) age-matched normotensive control, WKY. At the age of 6 and 16 weeks, blood pressure and the releases of NE from the locus coeruleus in SHR and KWY were measured by in vivo microdialysis at three different conditions: 1) normal, 2) elevated state of blood pressure by systemic injected phenylephrine and 3) increased state of neural activity by perfused phenylephrine into the locus coeruleus. The basal release of NE of SHR were significantly higher than that of WKY, Phenylephrine treatment caused elevation of blood pressure in both SHR and WKY in dose-dependent manner. Following phenylephrine injection, the releases of NE from the locus coeruleus of SHR were significantly decreased, whereas the significant change of NE in WKY was observed in the highest dose of phenylephrine. Phenylephrine perfusion into the locus coeruleus through microdialysis probe caused pressor responses and the pressor response in SHR was greater compared with that in WKY. The results from the present study suggests that the noradrenergic nervous system in the locus coeruleus may contribute as one of the development and maintenance factors for hypertension in SHR.

Chronic inflammation has been proposed as one of the main molecular mechanisms of aging and age-related diseases. Although evidence in humans is limited, short-term calorie restriction (CR) has been shown to have anti-inflammatory effects in aged experimental animals. We reported on the long-term treatment of daumone, a synthetic pheromone secreted by Caenorhabditis elegans in an energy deficient environment, extends the life-span and attenuates liver injury in aged mice. The present study examined whether late onset short-term treatment of daumone exerts anti-inflammatory effects in the livers of aged mice. Daumone was administered orally at doses of 2 or 20 mg/kg/day for 5 weeks to 24-month-old male C57BL/6J mice. Increased liver macrophage infiltration and gene expression of proinflammatory cytokines in aged mice were significantly attenuated by daumone treatment, suggesting that short-term oral administration of daumone may have hepatoprotective effects. Daumone also dose-dependently suppressed tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$ )-induced nuclear factor-${\kappa}B$ (NF-${\kappa}B$) phosphorylation in HepG2 cells. The present data demonstrated that short-term treatment of daumone has anti-inflammatory effects in aged mouse livers possibly through suppression of NF-${\kappa}B$ signaling and suggest that daumone may become a lead compound targeting aging and age-associated diseases.

The purpose of this study is to investigate the comprehension and production of various tense markings in Korean-speaking children with and without language delay. Thirty children with language delay(LD) and 30 typically developing(TD) children participated in the study. In each group, half were at the age of 4-years and the other half at 7-years. In both the comprehension and production task, 28 verbs containing four types of tense markings were used: past tense '-et ta', two present progressives '-ko itta', '-enta', and future tense '-elyeko hanta'. In the comprehension task, the children were presented with three printed still-scenes of video recording of a verb action, each representing future, present progressive, and past tense of the verb, respectively. Then they listened to the action verb with one of the 4 tense markings and had to pick the scene that matched the verb tense. In the production task, the children were given one of the three scenes and asked to produce the verb with appropriate tense marking. In both tasks, the LD children performed significantly worse than the TD children, and the older children performed significantly better than the younger children. Interestingly, the pattern of performances across different types of tense markings at the two language-age levels were closely similar in LD children and TD children. This similarity of groups seemed stronger in the comprehension task than the production task.

In this paper, the individual number of the future has depended not only upon the present individual number but upon the present individual age, considering the stochastic process model of individual number when the life span of each individual number and the individual age as a set, this becomes a Markovian. Therefore, in this paper the individual is treated as invariable, without depending upon the whole record of each individual since its birth. As a result, suppose {N(t), t>0} be a counting process and also suppose $Z_n$ denote the life span between the (n-1)st and the nth event of this process, (n{$geq}1$) : that is, when the first individual is established at n=1(time, 0), the Z$Z_n$ at time nth individual breaks, down. Random walk $Z_n$ is $Z_n=X_1+X_2+{\cdots}{\cdots}+X_A, Z_0=0$ So, fixed time t, the stochastic model is made up as follows ; A) Recurrence (Regeneration)number between(0.t) $N_t=max{n ; Z_n{\leq}t}$ B) Forwardrecurrence time(Excess life) $T^-I_t=Z_{Nt+1}-t$ C) Backward recurrence time(Current life) $T^-_t=t-Z_{Nt}$

A total of 2,580 sera of the patients who were consulted to the serology laboratory of the Seoul National University Hospital were collected in 1990. The sera were screened by micro-ELISA to detect IgG antibody reacting with Pneumocystis carinii antigen. The absorbances were 0.00 to 1.41 and mean 0.27±0.253. As the positive criterion was set absorbance 0.2 or more with 70% sensitivity, total positive rate was 44.4oA. Mean absorbances and positive rates were higher in children than in adults; 0.40 and 62.9% in 0 year group, 0.50 and 81.2% in 1 year group, 0.41 and 66.0% in 2-3 year group, 0.33 and 61.4% in 4-5 year group, 0.25 and 42.3% in 6-10 year group respectively. In the age groups over 11 years, the absorbances were in range of 0.16 to 0.23 and the positive rates were 26.1% to 41.5%. The present level of absorbances and positive rates could be regarded similar with those in normal Korean population. The present findings suggest that most humans are exposed to Pneumocystis within 2 years after birth and meet much less new antigenic challenge after 11 years in Korea.

Vertical growth is viewed as the solution to the problem of urban housing. The present study aims to be multifocal in approaching the phenomenon of apartment living in Lahore, Pakistan. The primary focus of the research was to evaluate the satisfaction with and favorability of vertical living among the dwellers; however, the research was extended to include the in-depth experiences of adolescents regarding privacy because it was observed that this age group was being neglected severely in the distribution of privacy in apartments, as well as in research. The data was first collected from 150 respondents through a survey, and then interviews of 10 adolescents were conducted to explore notion of privacy. The findings highlight that, despite being satisfied with the infrastructural aspects of the building, the residents do not prefer vertical living over horizontal housing. The adolescents in apartments also prefer horizontal housing over vertical living to avoid the feeling of crowdedness that is associated with vertical growth due to shared space and proximity. The utilization of spaces within apartments is associated with certain elements of development of the personality during this age. The findings of the present study can be helpful for sustainable vertical housing policy development and implementation.
