Although the stainless steel crowns have been recognized as the most effective and durable form of restoration for primary molars, they have been regarded by many dentists as having definite demerits such as invasive nature of procedural complexity and behavioral aspects of children. As an alternative to conventional technique of stainless steel crown restoration, the Hall technique was first introduced in 1988, which is characterized by just pushing the pre-contoured, cement filled crown form onto the abutment molar with no local anesthesia, no caries removal, no tooth preparation. According to several reports, this can slow, arrest, or even reverse the progress of caries. In addition, its atraumatic feature gives less discomfort and stress to children than conventional one, which is thought excellent especially in younger children. Also, It has been reported to be effective and acceptable to dentist, child patients and their parents. In this case study, three children with age of 4 years 5 months, 4 years 10 months, 6 years 4 months were treated with stainless steel crowns using Hall technique on first primary molar respectively. The teeth were free from pulpal, periapical pathology. After follow up of about 3 to 6 months period, the results showed clinically successful outcomes without any marked complication in pulp, tooth or soft tissue till now. But, it should be kept in mind that this technique is not proper to every child, every carious molar, or every dentist. Thorough distinction of indicated cases and continuous follow-up check is highly required. Conclusively, Hall technique might be an effective and realistic minimally invasive alternative for the carious primary molars especially in younger or disabled children, despite potential doubts on its efficacy and some definite limitations.

This study was done to analyze nutrition counseling services in health promotion center and to investigate demands of subjects for nutrition services. Data was collected through the survey of 90 subjects. The results were as follows. The results of people receiving nutrition services showed that 58.5% of the counseling group and 46.4% of the non-counseling group answered having experience with nutrition services. And 50% of them received nutrition counseling through individual counseling. Diet therapy with health check-up results also appeared the highest in contents of nutrition counseling. As a source of nutrition information and health knowledge, subjects relied heavily or most on the TV, internet, books, magazines, and newspapers. On the other hand, they relied much less on advice from dietitians, nutritionists, medical doctors and nurses. The experience of receiving nutrition services and thinking about nutrition education related positively. It showed that the counseling group (95.1%) was significantly higher than the non-counseling group (80.5%) in necessity of nutrition assessment. But, necessity of nutrition counseling wasn't significantly different between the two groups. The method of nutrition counseling subjects preferred was individual consultation. The subjects answered to having need of analysis and evaluation of nutrient intake and calorie prescription in nutrition assessment and individual nutritional status results explanation in nutrition counseling. In conclusion all people visiting health promotion centers need nutrition service of some kind.

후두기능의 전기생리학적 특징에 대한 관심은 1940년대부터 시작되어 1950년대와 1960년대에는 유럽 및 일본에서 Faborg-Anderson, Hirano 등이 후두근전도의 임상적 적용에 대해서 보고한바 있으며, 1970년대부터는 미국에서도 Bleir, Miller등이 후두근전도의 임상적 역할에 대해 보고하고 있다 이와 같이 후두근전도가 임상에 도입된 지 오래되었고 신경후두학 분야에서 후두근육의 전기생리상태를 알 수 있는 아주 중요한 진단도구이나 아직까지 후두근전도는 양적인 평가가 가능한 표준화된 검사는 아니고 내시경이나 방사선학적 검사처럼 경험이 있는 의사에 의해 판독되어지는 검사로 음성장애가 있는 모든 환자에서 집단검진(screening test)으로 이용될 수 있는 검사도구는 아니다. 후두근전도가 임상에서 유용하게 이용되고 있는 질환은 성대운동 장애와 연축성 음성장애이다. 최근 성대운동 장애에 대한 다양한 수술방법이 개발되면서 수술 방법 및 시기 결정, 예후측정에 후두근전도의 이용이 필수적이 되었으며 또한 연축성 음성장애 환자에서 어떤 후두 근육에 botulinum toxin을 주사할 지를 결정하는 데 이용하고 있다. 이번 강의에서는 위 두 가지 질환을 중심으로 후두근전도의 임상적 유용성을 살펴보기로 하겠다.

The purpose of this study was to examine how region-specific characteristics affect the occurrence of cardiac arrest. To analyze, we combined a unique data set including key indicators of health condition and cardiac arrest occurrence at the 244 small administrative districts. Our data came from two main sources in Korea Center For Disease Control and Prevention (KCDC): 2010 Out-of-Hospital Cardiac Arrest Surveillance and Community Health Survey. We analyzed data by using multiple regression, geographically weighted regression and decision tree. Decision tree model is selected as the final model to explain regional variations of cardiac arrest. Factors of regional variations of cardiac arrest occurrence are population density, diagnosis rates of hypertension, stress level, participating screening level, high drinking rate, and smoking rate. Taken as a whole, accounting for geographical variations of health conditions, health behaviors and other socioeconomic factors are important when regionally customized health policy is implemented to decrease the cardiac arrest occurrence.

The purpose of this study is to find a classification method with high accuracy in regard with sasang constitutional diagnosis. The BMI, blood pressure, pulse wave, and Sasang constitution diagnosed by a specialist was collected from 2848 subjects who were apparently healthy. Through a selective procedure, the data of 1635 subjects was used in the analysis. The results with the classification methods such as the discriminant analysis, regression, decision tree and neural network were compared with the diagnosis of a Sasang constitutional specialist. In result, the discriminant analysis method was hard to qualify the assumption of the equality of covariance matrices within constitutional groups. Moreover, without BMI, the decision tree and neural network methods were very sensitive to the change of the analysis data. Therefore, the Logistic regression and the decision tree is recommended on condition that the decisive factors of constitution are well concerned.
