The object of this study was to examine attitudes and knowledge of Korean dieticians about functional foods. We investigated their perceived knowledge and their attitudes regarding risks versus benefits, and recommendation about the use of functional foods; as well as their frequency of personal use, and the educational supports and training needs of dieticians. We developed a questionnaire to assess the dieticians' attitudes related to functional foods. This questionnaire was used for characterizing functional food-related attitudes on the basis of factor and reliability analysis in the following study. The questionnaires were distributed to 802 practicing dieticians working in Daegu and Gyeongsangbukdo. A total of 244 respondents (mean age $34\pm5.7$ years) returned the completed questionnaires through online surveys. Descriptive statistics and ANOV A were used to analyze data. Fewer than $2\%$ of dieticians claimed themselves to be knowledgeable about functional foods, more than $79\%$ consumed functional foods more than once a week, and $88\%$ of dieticians expressed an interest in receiving training about functional foods. Dieticians had favorable attitudes about the rewards from functional foods but were not confident about the safety and usage recommedation of these foods. The level of knowledge and educational support at their universities about functional foods affected the dieticians' attitudes regarding the rewards from and recommendation about the use of functional foods. These results suggest a need for additional educational opportunities to facilitate a better understanding of the risks and benefits of functional foods and their proper usage. Dietetics professionals must adapt to changes in health practices through effective educational programs integrating sufficient knowledge about functional foods.

The recent Web service field emerges as the fastest growing IT paradigm as a result of the increasing interest in SOA (Services-Oriented Architecture) and the expansion of B2B market. With an increasing number of Web service that provide similar features, it becomes more important to provide the most appropriate service for the user's request. A service user in general requires the quality information of Web service when selecting a service among a number of similar Web services. Yet, finding a service through UDDI (Universal Description, Discovery and Integration) does not consider the non-functional aspects of users because it is only based on the functional aspects. That is, the quality, non-functional aspect will be an important factor for the mutual success of the user and provider. Using 3 factors in the Qos factors of the existing studies: the execution cost, reliability, and the quality level, the QoS of Web service is saved and the factors for the QoS are recorded in order to consider non-functional factors when selecting a Web service in this study. The Quality Broker determines the rank and shows the desired result of the service for users. The Quality Broker suggested in this thesis can be used to select a Web Service that considers the user-oriented and non-functional factors.

The purpose of this study is to know about the consumption patterns of functional foods and their associated factors for contributing to the promotion of healthiness on Gwangju residents. The results obtained are summarized as follows: in terms of age, 35.9% of men (n=78) and 52.3% of women (n=128) are found in the age range of $45{\sim}54$ which comprises the highest portion of age distribution. 49.5% of subjects had college education or more. In the occupation category, 33.3% of the men had business job positions, and 39.8% of women were in the unemployed (housewife) category. Stress relief was the most important factor to maintain good health. 76.2% of the subjects have experience in consuming functional foods. The main reason for taking functional foods was to maintain health. Information and reliability of effectiveness were considered when selecting functional foods. Purchasing functional foods was motivated by family members, relatives, and/or the subjects themselves. Functional foods were mainly purchased from pharmacies or health food stores. Regular exercise, drinking, periodical medical checkups, and eating score all are taken into consideration with the consumption of functional foods.77.9% of subjects recognized functions for functional foods purchased. 18.8% of subjects experienced side effects after intaking functional food. Therefore, functional foods should be managed by the government and nutrition education for consumers should be required to encourage them to choose functional foods more satisfactorily and safely.

Objective : The purpose of this study was to investigate the factors affecting the surgical outcome and to compare the surgical results between transsylvian and transcortical approaches in patients with putaminal hematomas. Methods : Retrospective review of charts and CT scan images was conducted in 45 patients (20 transsylvian and 25 transcortical approaches) who underwent open surgical evacuation of putaminal hematomas. Mean Glasgow coma scale (GCS) score and hematoma volume were $7.5{\pm}3.2$ and $78.1{\pm}29.3\;cc$, respectively. The factors affecting the functional mortality were investigated using a multivariate logistic regression analysis. In addition, surgical results between transsylvian and transcortical approaches were compared. Results : None of the patients had a good recovery after the surgery. Overall functional survival rate and mortality were 37.7% and 31%, respectively. The only risk factor for functional mortality was GCS motor score after controlling age, history of hypertension, side of hematoma, hematoma amount midline shift, presence of intraventricular hemorrhage and surgical approach (p=0.005). Even though a transcortical approach was shorter in operative time (4.4 versus 5.1 hour) and showed a higher mortality rate (40% versus 20%) and lower functional survival (45% versus 35%) compared to the transsylvian approach, the differences were not statistically significant between the two groups. Conclusion : In patients who have large amounts of hematoma and require open surgical evacuation, the only significant risk factor for functional survival is the preoperative GCS score. Cortical incision methods such as transsylvian and transcortical approaches have no influence on the surgical outcome. To decompress the swollen brain rapidly, transcortical approach seems to be more suitable than transsylvian approach.

Objective : The aim of this study was to evaluate the effects of Aconiti ciliare tuber on the descending pain and the recovery of locomotor function that results from sciatic crushed nerve injury in rats. Method : In order to assess the effects of the aqueous extract of Aconiti ciliare tuber on the recovery rate of locomotor function, we investigated the walking track analysis, and for the effects on the pain control we investigated brain-derived neurotrophic factor (BDNF) and inducible nitric oxide synthase (iNOS) expression in the sciatic nerve and on the expressions of c-Fos in the ventrolateral periaqueductal gray (vlPAG) region resulting from the sciatic crushed nerve injury in rats. Result : Treatment with Aconiti ciliare tuber significantly enhanced the SFIvalue, enhanced BDNF expression, decreased iNOS expression, and suppressed c-Fos expression. The present results showed that Aconiti ciliare tuber facilitated functional recovery following sciatic crushed nerve injury in rats. The recovery mechanisms of SFI by Aconiti ciliare tuber might be ascribed to the increase of BDNF expression for nerve regeneration and reinnervation and to the suppression of iNOS expression for inhibiting nerve inflammation. Conclusion : In this process it has been shown that Aconiti ciliare tuber can be used for pain control and functional recovery from peripheral nerve injury.

Today, functional gloves must allow the wearer to perform many kinds of delicate work while protecting the hands from hazardous materials. In this study, multiple analyses of 3D hand measurements were performed to provide information on the hand size and shape required for the design of functional gloves for adult men. Size and shape characteristics were identified from 19 different hand measurements, and three factors were collected through factor analysis. The aggregated factor score was used to classify men's hand shapes into three types. These types showed different distribution patterns according to age, indicating a significant distribution difference between hand type and age group. Discriminant analysis extracted nine items that highly contributed to determining hand type. However, since the data provided by Size Korea have some limitations in fully representing hand shape, sampling additional types of hand measurements and using consistent conditions and methods are required for more accurate analysis.

Background: Deficiency in scapular muscle endurance (SME) is a risk factor for rotator-cuff-related shoulder pain (RCRSP). However, the exact relationship among SME, pain, and functionality remains unclear. This study aims to compare SME, pain, and functionality in RCRSP patients to those in age-sex-matched healthy controls. Methods: Twenty-three patients with RCRSP and 23 age-sex matched healthy controls were included in the study. SME was measured using a 1-kg dynamometer. Self-reported pain level was assessed using a visual analog scale. The Functional Impairment Test-Hand, Neck, Shoulder, and Arm (FIT-HaNSA) was also used to assess functional impairment. Results: The control group had higher SME and total FIT-HaNSA scores than the patient group (P<0.05). There was a statistically significant and positive correlation between SME and FIT-HaNSA scores in both groups (P<0.05). Conclusions: SME was affected by RCRSP. Pain and functional impairment were correlated with low SME.

Hypertension is the major factor of most death and high blood pressure (BP) can lead to stroke, myocardial infarction and cardiac failure. Moreover, hypertension is strongly correlated with body mass index (BMI). Although the exact causes of hypertension are still unclear, some of genetic loci were discovered from genome-wide association study (GWAS). Therefore, it is essential to study genetic variation for finding more genetic factor affecting hypertension. The purpose of our study is to conduct a CNV association study for hypertension-related traits, BP and BMI, in Korean individuals. We identified 2,206 CNV regions from 3,274 community-based Korean participants using the Affymetrix Genome-Wide Human SNP Array 6.0 platform and performed a logistic regression analysis of CNVs with two hypertension-related traits, BP and BMI. Moreover, the 4,692 participants in an independent cohort were selected for respective replication analyses. GWAS of CNV identified two loci encompassing previously known hypertension-related genes: LPA (lipoprotein) on 6q26, and JAK2 (Janus kinase 2) on 9p24, with suggestive p-values (0.0334 for LPA and 0.0305 for JAK2 ). These two positive findings, however, were not evaluated in the replication stage. Our result confirmed the conclusion of CNV study from the WTCCC suggesting weak association with common diseases. This is the first study of CNV association study with BP and BMI in Korean population and it provides a state of CNV association study with common human diseases using SNP array.
