The study analyzed the heat losses and the building energy efficiency grade by the energy simulation using the ENERGY# and ECO2 programs for the three types of Standard design of rural houses. It was calculated the energy efficiency rating by the ECO2 program for the rural housing standard design, and the energy demand and the energy consumption by each factor were compared and analyzed. And it analyzed energy consumption by element of each house by ENERGY # program. As a result, first in the evaluation of the energy efficiency grade of buildings by the ECO2 program, the rating for primary energy requirement for the housing newly built by the standard design of rural house is expected to range from 2 to 4 with 189.3 to $238.7kWh/m^2.a$. Second, the energy loss of each part of standard design of rural housing occurs in the order of ventilation 39%, window 33%, outer wall 14%, roof 9%, bottom 5%, and energy loss through ventilation and window occurs more than 70%. Third, the most beneficial effects on the energy efficiency grade is obtained the lowest grade of all three types by 2 when the lowering of the window and door heat transmission rate and the lowering of the light density, and the heat exchange ventilation device is not installed. Fourth, in the standard design of rural housing, the energy demand is occupied by heating > hot water > lighting order, and the order of the weight is changed in order of heating > lighting > ventilation > hot water. Fifth, building energy efficiency assessment system needs to establish policy for fixing rural housing energy as a practical device to ensure energy performance and quality.

Background: Adolescence is the transitional period between childhood and adulthood. We have to pay attention to their psycho-social problems as well as their physical symptoms. In this context, we need to investigate the adolescent depression tendency and its related factors. Method : From May to June in 1008, we chose one elementary school, one middle school and one high school in Seoul and surveyed for all students who were above the 4th grade of elementary school and their parents. We analyzed the data for 3,685 students. Result: From the 6th grade of elementary school to the 1st grade of high school, the girls' DSRS(Depression self-rating scale) score was significantly higher than the boys'. The DSRS score was increased from the 2nd grade of high school for boys and from the 1st grade of high school for girls. The Pearson correlation coefficient between age and DSRS score was 0.16(p<0.01) and that between APGAR and DSRS score was -0.45(p<0.01). The median number of psychosomatic symptoms of the past month was 6, and when students complained for more psychosomatic symptoms, the DSRS scores were higher. Those who drank or smoked ranked significantly higher in DSRS score; and, those who exercised regularly, had leisure activity, and had a faithful person for counselling ranked significantly lower in DSRS score. Conclusion : Adolescents who complained of many psychosomatic symptoms needed to be screened for depression. A primary physician have to intervene about health related behavior such as family function, smoking, exercise and relieving stress.

Objectives: Primary malignant tumors in the salivary glands are relatively rare. Because of the rarity and the different histopathologic patterns, it is difficult to establish a uniform treatment strategy. The prime treatment of salivary gland malignancy is the surgery, but the role of radiotherapy has been under debate. Radiation therapy combined with conservative surgical procedures may be as successful and perhaps more rational treatment than radical surgery alone. The aim of this study is to evaluate clinical pattern, incidence, treatment modality and outcome of the salivary gland maligancy. Materials and Methods: The medical records of 32 patients with malignant neoplasm of salivary gland who treated at the Keimyung university Dongsan hospital were analyzed retrospectively. Results: The overall 5 year survival rate was 77.9% stage I : 100%, stage II : 75%, stage III : 66.7%, stage IV : 55.6%). The 5 year survival rate according to tumor grade was 100% in low grade malignancy, 71.8% in high grade malignancy. The 5 year survival rate according to treatment modalities was as follows: Surgery only group was 83.3%, combined treatment group with surgery and posoperative radiation was 74.6%. Conclusion: The factors affecting prognosis is variable, but the stage at the time of diagnosis, site of lesion, tumor grade, histologic subtype were important factors. Surgery was the prime treatment tool and postoperative radiotherapy was also imperative in higher stage patient, high grade tumor, or patients with positive surgical margin.

It is rare for low-grade gliomas to disseminate to the leptomeninges. However, low-grade gliomas with dissemination to the leptomeninges have been occasionally reported in children, and have generally been associated with local recurrence. A 16-year-old boy sought evaluation for diplopia and gait disturbance. A brain magnetic resonance imaging (MRI) revealed pontine mass, which was proved to be fibrillary astrocytoma on biopsy, later. Radiation therapy (5400 cGy) was given and the patient's symptoms were improved. He was followed-up radiologically for brain lesion. Seven months after diagnosis he complained of back pain and gait disturbance. A brain MRI showed a newly-developed lesion at the left cerebellopontine angle without an interval change in the primary lesion. A spinal MRI demonstrated leptomeningeal dissemination of the entire spine. Radiation therapy (3750 cGy) to the spine, and adjuvant chemotherapy with a carboplatin plus vincristine regimen were administered. However, he had a progressive course with tumoral hemorrhage and expired 13 months after diagnosis. We report an unusual case of a low-grade brainstem glioma with spinal dissemination, but without local recurrence, and a progressive course associated with hemorrhage.

Background: Meningiomas are the second most common primary intracranial tumors after gliomas. Epigenetic biomarkers such as DNA methylation, which is found in many tumors and is thus important in tumorigenesis can help diagnose meningiomas and predict response to adjuvant chemotherapy. We investigated aberrant O6-methyl guanine methyltransferase (MGMT) methylation in meningiomas. Materials and Methods: Sixty-one patients were classified according to the WHO grading, and MGMT promoter methylation status was examined via the methylation-Specific PCR(MSP) method. Results: MGMT promoter methylation was found in 22.2% of grade I, 35% of grade I with atypical features, 36% of grade II, and 42.9% of grade III tumors. Conclusions: There was an increase, albeit not statistically significant, in MGMT methylation with a rise in the tumor grade. Higher methylation levels were also observed in the male gender.

After entering an elementary school, in fact, a number of children regard mathematics as one of very difficult subjects because of its abstractiveness. This is caused by the fact that their basic thinking power is not yet formed or they can not understand the special quality of mathematics. So this article emphasizes the need to build up the higher logical thought and a basic mathematical concept at the lower grade elementary school stage in which the loaming activity on mathematics begins in earnest, that is, at the stage before having an experience on the calculating activity using numbers. But at present the lower grade elementary school students in our country do not understand the special quality of mathematics composed of a various symbolic system and lay stress upon mathematics learning attached to the calculative activity. In order to make the right mathematical concept of the lower grade elementary school, the basic knowledge and ability as follows is sure to be formed. 1) the foundational logical manipulation activity and knowledge 2) the using ability of the sign and symbolic system At the stage on which mathematics learning activity begins, it is a very important task to make the right concept of the abstractive math and nurse the capability for finding mathematical relations covered under the sign system through the continuos loaming activity on . Through the basic logical manipulation activity and the game activity of sign for lower grade elementary school students mentioned in this article, they can not only foster the higher level logical thinking power and the foundational calculative ability but also bring up the interest on the activity of establishing a new problem solving strategy.

Objective : Advancements in AVM surgical techniques for cerebral arteriovenous malformation (AVM) underscore its efficacy. Our research aims to showcase the positive outcomes of treating low-grade AVMs surgically, focusing on safety and effectiveness. Methods : We retrospectively reviewed 55 patients (36 males and 19 females; average age 37.4 years) with Spetzler-Martin (S-M) grade 1 and 2 AVMs who underwent surgical resection between January 2009 and December 2022. Results : In our study, 55 patients with S-M grade 1 and 2 AVMs underwent surgical resection, evenly divided between grades 1 (50.9%) and 2 (49.1%). Intracranial hemorrhage was the primary symptom in 74.5% of cases. Pre-operative Glasgow coma scale (GCS) scores revealed 69.1% of patients scored above 13, with 18% below 8. Successful resection was achieved in 87.3%. Postoperatively, 95.5% of ruptured and 90.9% of unruptured AVM patients showed lower or same modified Rankin scale scores. Poorer outcomes were significantly linked to lower GCS scores and intranidal/flow-related aneurysms through multivariate logistic regression. Postoperative seizures noted in nine patients, were exclusive to the ruptured AVM group. Conclusion : Our findings indicate surgical resection as a beneficial treatment for low-grade AVMs, yielding high cure rates and positive functional outcomes in both ruptured and unruptured cases. Preoperative GCS scores and the presence of associated aneurysms are predictive of postoperative functional status. Additionally, managing postoperative seizures effectively is key to enhancing prognosis.

The purpose of this research is to determine the influence of affectionate child-rearing behavior on children's self esteem. The sample group was composed of 200 forth and sixth grade elementary school students. The statistics used for this data were frequency, percentile, averages, standard deviation, Cronbach's alpha, t-test, Pearson's correlation, and stepwise multiple regression analysis. The major findings of the research were as follows: First, the scores of affectionate child-rearing behavior(3.60), global self-worth(3.58), social acceptance(3.46) and behavior conduct(3.28) were higher than the mean scores. On the contrary the scores of cognitive ability(2.95), physical ability(2.94) and physical appearance(2.85) were lower than the mean scores. Second, there were significant differences in cognitive ability based on gender(p＜.01) and global self-worth based on grade(p<.05). Third, the influence of affectionate child-rearing behavior on children's self esteem was found to be significant due to the sub-areas of self-esteem. Affectionate child-rearing behavior affects all sub-areas of self-esteem. Affectionate child-rearing behavior affects cognitive ability(p<.001), physical ability(p＜.01), physical appearance(p＜.01), social acceptance(p＜.001), behavior conduct(p＜.01) and global self-worth(p＜.001). In addition, gender(p＜.01) affects cognitive ability and grade(p＜.05) affects global self-worth.

Background: Breast cancer (BC) is a major health issue worldwide as well as in Pakistan. All women belonging to any race, ethnicity or lineage are in danger of developing breast cancer. Significant factors influencing the development of breast malignancies are the genetic background, environmental conditions, reproductive parameters, the consequences of female hormones both intrinsic and extrinsic, alteration of immune status, and biologic determinants. Materials and Methods: Overall 150 biopsy proven patients were included in the study. Samples were submitted for histopathology and determination of estrogen and progesterone receptor expression and HER-2/neu status. Associations with other characteristics like age, tumor stage, node involvement, histological grade were also studied. Results: Mean age at presentation was 46.7 years. The majority had invasive ductal carcinoma, 100 (84.7%), and were in stage pT3, 54 (45.7%). Important relationships (P<0.05) were found among ER, PR positivity, and Her 2 neu overexpression. However, no noteworthy link was identified amongst ER, PR, Her 2 neu and tumor grade, stage, age, lymph node involvement except for the menopausal status. Conclusions: In summary, breast cancer patients featured an advanced stage of disease, more lymph node involvement, and moderately high grade tumors and with more estrogen, progesterone receptor and HER-2 positive tumors.
