Purpose: Many researchers have established a connection between sleep disturbances and the symptoms of temporomandibular disorder (TMD) in adults, but there are a few studies targeted at adolescents with TMD. The aim of this study was to analyze the sleep pattern of adolescents with TMD and to determine the effect of poor sleep quality on their clinical symptoms. Methods: The subjects were composed of 47 adolescents with TMD. The sleep pattern and preliminary information of patients were measured by self-reported questionnaires; Pittsburgh Sleep Quality Index (PSQI) and Questionnaire for TMD analysis. TMD pain was scored using the Numerical Rating Scale. The Kruskal-Wallis test, Mann-Whitney U test, Fisher's exact test and logistic regression were used for statistical analysis. Results: The poor sleeping group had statistically more females (25.00% males, 75.00% females) than the good sleeping group. As compared with that of good sleepers, sleep quality of poor sleepers was significantly worse in the items of subjective sleep quality, sleep latency, sleep duration, sleep disturbances, daytime dysfunction and global PSQI score. The sleep time of adolescents was much longer during vacation ($7.20{\pm}1.38hours$) than during school days ($6.10{\pm}1.26hours$). Poor sleep of patients was associated with the pain in the ear or in front of the ear, in the face, jaw, throat or temple and in neck or back. Adolescents with pain in those areas had significantly higher proportion of poor sleepers than adolescents with no pain in those areas. Conclusions: The high ratio of girls in poor sleeping group could reflect the greater prevalence of TMD in women than in men. Pain in peri-temporomandibular joint areas, neck or back could negatively influence sleep quality of adolescents with TMD.

청소년의 성폭력 개념과 원인에 대한 인식을 규명하기 위해 중 고등학생 694명을 대상으로 설문지 조사를 실시한 결과는 다음과 같다. 첫째, 청소년의 성폭력에 대한 인식정도를 유형별로 볼 때. '신체적성폭력'을 성폭력이라고 인식하는 정도가 가장 높았고 그 다음이 '언어적성폭력', '심리적성폭력 순이었다. 성별로는 남학생이 여학생보다 신체적 성폭력을 성폭력으로 인식하는 정도가 훨씬 낮았다. 이는 남학생은 일반적으로 신체적 성폭력의 가해자인 남성의 입장에 서서 자기중심적으로 사고하기 때문인 것이다. 따라서 성폭력 예방을 포함한 성교육은 여학생보다 남학생에게 더욱 필요하다고 하겠다. 반면 나이에 따른 차이를 보면, 고둥학생이 중학생보다 심리적 성폭력을 성폭력이라고 인식하는 경향이 적었다. 이는 생활연령이 증가할수록 음란물에 노출되는 경험이 많아져 성폭력의 범위를 축소시켜 인식한 결과이다. 따라서 성폭력 예방을 위해서는 주위환경의 정화가 무엇보다 우선되어야 할 것이다. 둘째, 청소년이 인식하는 성폭력 원인을 유형별로 살펴보면 청소년은 사회 환경'을 가장 높은 성폭력 원인으로 인식하였고, 그 다음으로 '지역사회역할'을 지적하여 성폭력 근절을 위해서 주위 환경이 중요함을 다시 한번 일깨워주고 있다. 또한 성폭력 원인에 있어서 남학생은 피해자를 성폭력 원인으로 인식하고 있음으로써 남학생에 대한 성교육의 필요성을 강력히 말해주고 있다.

Background: The objective of this study was to determine a diagnostic classification scheme using a decision tree based model. Materials and Methods: The study was conducted as a retrospective case-control study in Imam Khomeini hospital in Tehran during 2001 to 2009. Data, including demographic and clinical-pathological characteristics, were uniformly collected from 624 females, 312 of them were referred with positive diagnosis of breast cancer (cases) and 312 healthy women (controls). The decision tree was implemented to develop a diagnostic classification scheme using CART 6.0 Software. The AUC (area under curve), was measured as the overall performance of diagnostic classification of the decision tree. Results: Five variables as main risk factors of breast cancer and six subgroups as high risk were identified. The results indicated that increasing age, low age at menarche, single and divorced statues, irregular menarche pattern and family history of breast cancer are the important diagnostic factors in Iranian breast cancer patients. The sensitivity and specificity of the analysis were 66% and 86.9% respectively. The high AUC (0.82) also showed an excellent classification and diagnostic performance of the model. Conclusions: Decision tree based model appears to be suitable for identifying risk factors and high or low risk subgroups. It can also assists clinicians in making a decision, since it can identify underlying prognostic relationships and understanding the model is very explicit.

Some segment or segments of the body must compensate for the heel, and the higher the heel the greater the compensation. Such compensation was once generally thought to take place in the lumbar region and therefore to increase the lumbar lordosis. The purpose of this study is to analyze changes of lumbar sagittal curvature in barefoot and 6cm 12cm high-heel stance. We selected 19 subjects(11 males, 8 females} without history of lower back pain, significant spinal abnormality. And lateral view X-ray of lumbar region from T12 to S1 was taken of each individual. On each X-ray film, lumbar lordotic angle lumbosacral angle and lumbar segmental angles were measured by Cobb method. We drew the following interpretations from the analysis of measured variables of the lumbar region. 1. In comparison of barefoot 6cm heel 12cm heel stance, lumbar lordotic angle had a tendency to decrease according as the heel height was higher. The change in lumbar lordosis measured in high-heel stance was inconsistent with clinical forkelord of hyperlordosis in wearers of high-heeled. 2. Lumbar lordotic angle from T12 to L5 showed sex difference, and was more lordotic in female(p<0.05). 3. There was no sex difference in lumbosacral angle and lumbar segmental angles(p>0.05). 4. There was a significant correlation between lumbar lordotic angle and lumbosacral angle(r>0.60).

The purpose of this study was to identify the relationship between clothing Brand Loyalty and lifestyles The questionnaire was administered to 644 males and females aged 30-40 in Taegu during November 24 to November 28 of 1997. Data was analyzed by frequency, percentage, mean, standard deviation, factor analysis, reliability test MANOVA and ANOVA by using SPSS package. 1. The lifestyles of the responednts were classified into five types such as consumption-oriented, economics-oriented, social-oriented, family-oriented, and conservative-oriented type. 2. The results of clothing Brand Loyalty and lifestyle analysis were as follows; 1) In case of males, the group of consumption-oriented type and in case of females, three groups of consumption-oriented, social-oriented and family-oriented types had great concern for brand loyalty in lifestyles and brand loyalty. 2) With relation to brand loyalty and lifestyles, thirties-aged respondents had a positive tendency to brand loyalty in consumption-oriented and social-oriented types, but forties-aged ones had a positive tendency to brand loyalty in consumption-oriented, social-oriented and family-oriented types. 3) With relation among the academic careers, lifestyles and brand loyalty, three groups(consumption-oriented, social-oriented and family-oriented types) under high-school graduates made high response to brand loyalty, and two groups (consumption-oriented and social-oriented types) of college graduates showed something responsive to it and the consumption -oriented persons of graduate school and upward made response to brand loyalty. 4) With relation among an income, brand loyalty and lifestyles, three types(consumption-oriented, social-oriented and family-oriented types) of an income not exceeding one million and half won a month were related to brand loyalty. And two types(consumption-oriented and social-oriented types) of an income below two million won a month made high response to brand loyalty. And the consumption-oriented type of an income below three million won and more than three million and half a month made good response to brand loyalty. 5) In general relation between brand loyalty and five lifestyles, the consumption-oriented type made positive response to brand loyalty and the social-oriented type was in the second place and the family-oriented type ranked next to the social-oriented type. But the economics-oriented and conservative-oriented type were not related to brand loyalty. 6) It was found that there was a difference between brand loyalty and the same lifestyle according to individual characteristics.

Background: Esophagogastroduodenoscopy (EGD) is the standard technique for diagnosis of patients presenting with upper gastrointestinal symptoms. Some reports have shown high prevalence of esophageal cancer in the northern part of Afghanistan. The aim of this study was to investigate epidemiological profile of esophageal cancer among patients in this region. Materials and Methods: We identified 364 consecutive patients that received EGD examinations to examine upper gastrointestinal tract at the endoscopy unit of Balkh regional Hospital from March 2012 to March 2013. The case subjects included both in-patients and out-patients aged 16 years or more. We evaluated the results retrospectively. Results: The cases consisted of 184 (51%) males and 180 (49%) females. The mean age was $47.3{\pm}17.8$ and the age range 17-88 years. Ninety two cases had esophageal cancer, out of which 58 (63.0%) were male. The mean age at time of diagnosis was $57.8{\pm}13.2years$. Uzbek-Turkmen peoples were more common among patients with esophageal cancer (52.2%). Dysphagia was the most frequent symptom among patients with esophageal cancer at the time of presentation, seen in 77 (84.8%) of cases. Conclusions: Our results showed high incidence of esophageal cancer in the northern part of Afghanistan, especially in the Uzbek-Turkmen ethnic group.
