Background: Cervical radicular pain can arise fromvarious structures, including spinal nerves, discs, zygapophyseal joints, ligaments, and myofascial connective tissue. However, no adequate experiments have been found regarding methods for the microadhesiolysis of adhesional connective tissue around the zygapophyseal joints and nerves. The first objective of this study was to ascertain the effect of fluoroscopy guided interventional microadhesiolysis and nerve stimulation (FIMS) on chronic cervical radicular pain caused by zygapophyseal joint dysfunction. The second objective was to identify the duration of pain alleviation, as well as commonly occurring regions for zygapophyseal joint dysfunction. Methods: Twenty-eight patients were diagnosed with cervical radicular pain. The cervical zygapophyseal joints and adhesional structures around the cervical zygapophyseal joints were stimulated by adhesiolysis with a rounded needle; the procedure was performed once every second week. A visual analogue scale (VAS) for pain and neck range of motion (ROM) were used as indices for evaluating the degree of pain 1 and 3 months after completion of the procedures. A relief effect of FIMS was accepted when the VAS index decreased 50% compared with a previous VAS, and when there was absence of limitation of ROM. Results: Among the patients, 52% showed zygapophyseal joint dysfunction in C5-6, 38% in C4-5, 7% in C2-3, and 3% in C6-7. After performing FIMS, the VAS index decreased in most of the patients after 1 and 3 months (92.8% and 75%, respectively), and treatment frequency was $2.7{\pm}1.2$. There was no correlation between the number of FIMS procedures and the degree of VAS. Conclusions: FIMS is considered an effective modality in patients suffering from cervical radicular pain.

Hypertension is the major risk factor for cardiovascular disease which is considered the leading cause of death in Korea. Since nonpharmarologic dietary intervention is recommended as the first step in the management of hypertension, evaluation of intervention programs is needed to formulate strategies for improving patients' dietary adherence. This study was designed to evaluate the overall effectiveness of a hypertension nutrition education program (HNEP) at a public health center, by assessing changes in nutrition knowledge, food attitude, self-efficacy, dietary behavior, and nutrient intake after program completion. An HNEP was conducted in Suwon city for 5 months in 1999 by a public health center. The program provided 3 sessions of group education with individual nutrition counseling. Thirty-five patients participated fully in the program out of 62 enrollees. Data about nutrition knowledge, food attitude, self-efficacy, dietary behavior, and intake (24-hour recall) were collected before (baseline) and after the program. Post program results indicate the following : 1) nutrition knowledge and perception of importance of nutrition significantly increased, 2) food attitudes also improved, 3) the self-efficacy for maintaining a low salt diet was increased significantly, whereas self-efficacy for maintaining a low fat diet or dietary guidelines was not improved, 4) frequency of intake of processed food, animal fat, and sweets as well as frequency of dining out were significantly reduced, 5) nutrient intake was not improved after the program, 6) the most serious barrier for participating in the program and practicing diet therapy was lack of time and willingness. In conclusion, it appears that HNEP might improve food attitudes, individual perceptions and self-efficacy for desirable eating behavior, but it might not improve dietary intake. It follows then, that a long term intervention program may need to increase effectiveness of patient dietary adherence.

study deals with the reliability assesment for the 5-year phases of a suspension bridge construction in Korea. The main objectives of this study are; (1) the evaluation of the reliability of a suspension bridge by considering an ultimate limit state for the fracture of main cable wires, (2) the determination of the critical phases among 28 construction stages for the deck erection, and (3) the evaluation of the reliability of the limit state for the erection control during construction stages. The research and the design of the suspension bridge have been focused on the state of construction mainly based on empirical data. Based on the recent survey of the distribution of accidents in Korean railways, over 80% of the accidents related to the uncertainties in human error, planning, design, materials and loads during construction have ben reported before the completion of construction. While many researches have evaluated the safety of bridges, the uncertainties in the construction phases have not been well treated in a guidelines or a specifications. An improved adaptive response surface method is used for the risk assessment in the construction phases of the target suspension bridge.

The principal objective of this study is to determine the most appropriate methods to increase global recognition of Korean food. In service of this objective, interviews were conducted with Korean food specialists who worked for a Korean culinary educational institute in Seoul, as well as cooking experts who worked for restaurants in super deluxe hotels. The study was conducted for 10 days from Feb $21^{st}$ to March $2^{nd}$ in 2009. The results of the study were summarized and synthesized into some key opinions. First, one of the main concepts in Korean culinary education should involve the selection of a small group of the best members and training them to a world class level at a traditional HanOk style institute. Second, to establish a standard for trainee recruitment, we selected a group of members consisting of about 20 persons over the age of 18 years who had earned a degree or were scheduled to graduate from university chef training and had also worked for over 5 years in the field, additionally, foreigners were allowed to apply to the institute. The educational term is one year and some benefits, such as a fixed amount of subsidies to help in daily living, free dormitory housing a certificate of course completion, and an employment guarantee. Third, the educational program consisted of two stages one was the specialist course in which traditional foods were covered and the other was the menu development course, which dealt with the creation of new Korean foods. Fourth, unique programs, including specialized foreign foods experience halls or commission education, were instituted in an effort to raise the level of world recognition of the superiority of Korean food.

This research aims to evaluate the effects and the shortcomings of strategies for teaching paraphrasing to foreign university students. For this study, the effects of teaching paraphrasing skills on student's academic writing was investigated through the assessment of pre- and post-test writing tasks and through a focus group interview. The teaching of paraphrasing was divided into 3 instructional sessions and the focus group interview was conducted at the end of the last session. After each instructional session three trained assessors evaluated the outcomes of pre and post task writings; the in-depth focus group interviews were conducted on seven of the students in order to define better positive effects as well as shortcomings. By comparing the scores of pre- and post-task assignments it is possible to affirm that there is a meaningful difference for overall scores; moreover, in an analysis conducted on each single sub-element of the paraphrasing skill, it emerged that except for "task completion", all other four elements of "structure", "understanding core content", "change of expression" and "academic expressions" showed a statistically significant improvement in performance. On the other hand, as a result of the focus group interview, it was possible to individuate as main shortcomings insufficient vocabulary knowledge, poor overall comprehension of the reference material, lack of practice and difficulty in connect sentences organically. It is possible to consider these elements as limiting factors in understanding the reference material and making correct citations by the students. Therefore, we suggest as supplementary instructional strategies a deeper attention to the difficulty level of the text, the introduction of devices to understand better the content of the reference material and an integrated practice of the paraphrasing skill.

Objectives The purpose of this study is to provide Korean version of mild traumatic brain injury assessment tool. Methods The original version of acute concussion evaluation (ACE) was translated into Korean, and it was then back-translated into English without any prior knowledge of ACE. Finally, the pre-final version of Korean version of acute concussion evaluation (K-ACE) was derived. 49 Korean patients who had been diagnosed with mild traumatic brain injury participated in the study and completed K-ACE. Overall, 44 data were used to analyze findings. Validity of the study was assessed based on Concurrent validity. Reliability was also evaluated using Cronbach's ${\alpha}$ and the intraclass correlation coefficient. Results The Cronbach's ${\alpha}$ value for each item presented a proper level of internal consistency with results of 0.711 to 0.893 in two evaluations, respectively. The intraclass correlation coefficient of the retest reliability was marked as 0.892 (95% CI 0.840~0.933). Concurrent validity demonstrated positive correlations between K-ACE and Korean version of postconcussional syndrome questionnaire. Conclusions The K-ACE is concluded as a valid and reliable tool for measuring mild traumatic brain injury and post-concussion symptoms. Upon completion of the follow-up study, the K-ACE will be well-utilized by both clinicians and researchers.

Energy consumption savings in buildings should be reviewed in diverse areas such as air conditioning system and lighting responsible for cooling and heating, and energy management systems such as BAS (Building Automation System) and BEMS (Building Energy Management System) are introduced to improve energy consumption efficiency and to promote economic control of related facilities by integrated management of energy generated and consumption in buildings. The measured building of this study uses regenerative geothermal system. Measured values of heat pump and system COP were 4.7 and 4.2 respectively, and they were found to be higher 11.9% and 23.5% than rated values. As a result of analyzing the air conditioning and lighting energy from the first floor to the fourth floor performing the air conditioning, the second and third floors, which have a high frequency of use, are compared with the first and fourth floors 50% higher energy consumption ratio. On the other hand, the general heat storage system uses the nighttime power of the previous day to store heat and use it the next day. The total number of days of abnormal operation during the summer season is 61 days. The electricity cost corresponding to the abnormal operation is 1,840,641 KRW, and the normal operation using the nighttime power is 1,363,561 KRW, which is difference of 477,080 KRW, 35% increase in cost. We will utilize it as the main data of BEMS through analysis of winter operation characteristics as well as summer operation characteristics.

This study explores the effects of business consulting on the business performance of firms by using a unique survey for various industry sectors in Korea. We attempt to build a consulting model that shows the structural relationship between consulting factors and consulting performance. Moreover, through the consulting model, we conduct the analysis of elasticity of consulting factors and the group analysis based on firm age. First, the findings show that all consulting factor has a positive impact on the consulting performance, but in the results of factor elasticity, they have a somewhat different impact. Second, while the support of CEOs is relatively more elastic than other consulting factors with respect to the completion of consulting projects, the institutional condition for consulting is relatively more elastic than other factors with respect to the contribution to business performance. Third, since the high-firm age group has a greater capacity to absorb and utilize external knowledge and resource, the consultant competency and institutional conditions have a more impact on the consulting performance than the low-firm age group. On the other hand, in the low-firm age group, the result indicates that the support of CEOs has a more impact in the consulting performance than the high-firm age group. According to the total effect, the support of CEOs in the entire model has the highest impact on the consulting performance. Thus, it is probably difficult to achieve the improvement of business performance through consulting as well as the successful consulting projects without the CEOs' commitment and awareness about the consulting projects.
