  • In the twenty first century, people experience a lot of stresses by psychological, social and environmental impetus. If the stress is excessive, it can become a problem and finally lead to diseases. Foot bath makes the body warm starting with the feet, controls the blood circulations and autonomic nervous systems. This study aims at examining the effects of stress and fatigue of senior students preparing for college entrance examination by foot bath with the aroma essential oil and the fermentation extracts. The experimental period was from March 30 to April 18, 2009. The study objects were 21 senior students of C Girls' High School in Cheonan. They were divided into 3 groups and treated 20 times. The first group was a foot bath group with Artemisia Herbal fermentation extracts. The second group was a foot bath group with the blending aroma essential oil of grapefruit, cypress and cedarwood. The third group was not treated. In the case of difference of physical and psychological stress, there was a reduction of 18.43 and 16.71 for the fermented extract group and 10.71 and 9.43 for the aroma group, while a reduction of 0.43 and 0.29 for the control group, respectively. This shows that foot baths using fermented extracts and aroma had lower physical stress compared to the control group (p<.01). For the difference of fatigue, there was a reduction of 19.14 for the fermented extract group, 11.57 for the aroma group and 0.07 for the control group, showing that foot baths accompanied by fermented extracts and aroma used in this study having lower fatigue compared to the control group (p<.01). The fermented extract group (M=55.71) had the highest level of satisfaction after foot baths, followed by the aroma group (M=49.14) and the control group (M=33.29). Duncan's post hoc test showed that there was a statistically considerable difference between the tests groups and control groups (p<.01). Through the results of this study, it was found that foot baths using bathing supplements were very effective for reducing stress and fatigue.

  • There is a belief in the construction industry that the traditional court system may not be an ideal forum to effectively and efficiently resolve construction disputes due to the protracted proceedings and the three tier appeal system resulting in a long delay in the final and conclusive settlement of the dispute, relatively high costs involved, the lack of requisite knowledge and experience in the relevant industry, etc. Hence, they assert that certain alternative dispute resolution ('ADR') methods, such as mediation, conciliation, arbitration or a new system for dispute settlement in the form of any combination thereof should be developed and employed for construction disputes so as to resolve them more promptly and efficiently to the satisfaction of all the disputants concerned. This paper discusses certain merits of such assertions and the need for additional considerations for effective resolution of the construction disputes in light of the complexity of the case, importance of expert witnesses, parties' relationship and non-level playing field of the construction industry and so on. At the same time, however, given the inherent nature of disputes rendering the parties involved in an adversarial position, it would rather be difficult, if not practically impossible, to satisfy all the parties concerned in the dispute. Accordingly, in this study, it is also purported to address the demerits of such assertions by studying the situation from a more balanced perspective, in particular, in relation to the operation of such ADRs. In fact, most of such ADRs as stipulated by special acts, such as the Construction Industry Basic Act of Korea, in the form of mediation or conciliation, have failed to get support from the industry, and as a result, such ADRs are seldom used in practice. Tn contrast, the court system has been greatly improved by implementing a new concentrated review system and establishing several tribunals designed to specialize in the review and resolution of specific types of disputes, including the construction disputes. These improvements of the court system have been warmly received by the industry. Arbitration is another forum for settlement of construction disputes, which has grown and is expected to grow as the most effective ADR with the support from the construction industry. In this regard, the Korean Commercial Arbitration Board ('KCAB') has established a set of internal rules end procedures in operation to efficiently handle construction disputes. Considering the foregoing, this paper addresses the most important elements of the arbitration, i.e., arbitration agreement and arbitral award, primarily focusing on the domestic arbitrations before the KCAB. However, since this parer is prepared for presentation at the construction disputes seminar for the public audience, it is not intended for academic purposes, nor does it delve into any specific acadcmic issues. Likewise, although this paper addresses certain controversial issues by way of introduction, it mainly purports to facilitate the understanding of the general public, including the prospective arbitrators on the KCAB roster without the relevant legal education and background, concerning the importance of the integrity of the arbitration agreement and the arbitral award. In sum, what is purported in this study is simply to note that there are still many outstanding issues with mediation, conciliation and arbitration, as a matter of system, institutional operation or otherwise, for further study and consideration so as to enhance them as effective means for settlement of construction disputes, in replacement of or in conjunction with the court proceeding. For this purpose, it is essential for all the relevant parties, including lawyers, engineers, owners, contractors and social activists aiming to protect consumers' and subcontractors' interests, to conduct joint efforts to study the complicated nature of construction works and to develop effective means for examination and handling of the disputes of a technical nature, including the accumulation of the relevant industrial data. Based on the foregoing, the parties may be in a better position to select the appropriate dispute resolution mechanism, a court proceeding or in its stead, an effective ADR, considering the relevant factors of the subject construction works or the contract structure, such as the bargaining position of the parties, their financial status, confidentiality requirements, technical or commercial complexity of the case at hand, urgency for settlements, etc.

  • Purpose: This study has been conducted in order to examine the oral health status and dental prostheses status, and the effects of dental prostheses to the oral health related quality of life among the elderly using social welfare centers. Material and methods: For this purpose, the researcher conducted a questionnaire survey and oral examination of 275 samples of old persons using 7 social welfare centers located in Daejeon metropolitan city. The oral health related quality of life was measured by GOHAI (Geriatric Oral Health Assessment Index). Results: 1. The less age and the more education and the more subjective economic status and living with spouse of family status, the higher GOHAI showed. 2. Mean age of first using of removable denture is 62.11 years old and average life cycle of removable denture is 10.76years. 57.5% of study subjects use removable denture and complete denture user of study subjects are 13.8%. 3. In the case that they use fixed prostheses rather than removable ones and in the complete denture they use both sides (upper and lower) rather than single side, showed higher GOHAI. 4. In the case that they showed higher degrees of satisfaction with dental prostheses and can use them always and showed no necessity for new dental prostheses and denture adaptation is good, GOHAI showed higher. Conclusion: In order to improve oral health related quality of life among the elderly who have many missing teeth, it is required to restore their masticatory ability to the normal level by restoring the missing teeth which has lost its function through providing proper dental prostheses.

  • Purpose: The purpose of this prospective study is to compare the results of arthroscopic reconstruction of ACL using autologous hamstring tendon (Group 1) and autologous bone patella tendon bone (Group 2). Materials and Methods: From Jan. 2004 to Dec. 2007, fifty patients were analyzed in this study. A single surgeon performed the ACL reconstruction with autologous hamstring tendon (25 patients) and autologous bone patella tendon bone (25 patients) alternatively each other. The mean follow up period of two groups was 38 months (range 25~58 months). We evaluated the result of Lachman test, Pivot shift test as a physical examination and Lysholm score, Tagner activity scale as patients' satisfaction and functional status and Telometer for anterior instability of each groups at the time of final follow up. Results: In final results, negative or mild positive findings on Lachman test were 24 out of 25 cases (equally) in each groups.) Twenty two cases in the Group 1 and 21 cases in the Group 2 were negative on Pivot shift test. Lysholm scores mark 94.6 points in group 1 and 92.3 points in group 2 at the final follow up and Tegner activity scales mark 8.5 points (Group 1) and 8.1 points (Group 2) at the time of last follow up and there were no differences between the two groups statistically. The numbers of patients who have less than 5 mm of anterior translation of tibia under telometer at 20 degrees of knee flexion are 24 cases in group 1 and 23 cases in group 2. Conclusion: The overall improvements of clinical scores (Lysholm scores and Tegner Activity scales) of the group 1 were a little bit superior to those of the group 2, but there were no significant statistical difference between two groups.

  • Purpose: The purpose of this study is to compare the results of the arthroscopic reconstruction of ACL using autologous hamstring tendon and autologous bone-patellar tendon-bone. Materials and Methods: From January, 2000 to December, 2004, 120 patients underwent arthroscopic ACL reconstruction using autologous hamstring tendon(60 cases) and autologous bone-patellar tendon-bone(BPTB)(60 cases). The mean followed up period of hamstring tendon group was 42 months(range $24{\sim}69$ months) and patellar tendon group was 52 months(range $24{\sim}84$ months). At the time of the final follow up, sixty patients in each group were evaluated the results of physical examination, activity level, patients' satisfaction, functional status, and objective anteriror stability using KT-2000 arthrometer. Results: At the time of the final follow up we compared the two groups who had ACL reconstruction using either autologous hamstring tendon or BPTB, and the final results of the Lachman test showed negative, or mildly positive in 85%(51 cases) of the hamstring tendon group and 90%(54 cases) of the BPTB group. Pivot shift test indicated positive in both groups, 8%(5 cases) and 5%(3 cases) respectively and showed no statistically significant difference. The evaluation of the anterior laxity using the KT-2000 arthrometer revealed no significant difference in the hamstring and BPTB groups: differences less than 3 mm compared to the healthy side were 85%(51 cases) and 90%(54 cases)(p>0.05). The Lysholm score improved from a preoperative score of 51 to a postoperative score of 79.1 in the hamstring groups and from 52 to 82.2 in the BPTB groups. According to the IKDC rating system, 87%(52 cases) were normal or near normal in the hamstring group. In the BPTB group, 83%(50 cases) were normal or near normal. The Tegner score for the hamstring groups was 4.8 preoperatively and 7.1 at the final follow up, and the Tegner score for the BPTB groups was 4.5 preoperatively and 7.3 after the last follow-up. The anterior knee pain was found in 7%(4 cases) in the hamstring tendon group and 10%(6 cases) in the patellar tendon group. Conclusion: Arthroscopic ACL reconstruction using both the autologous hamstring tendon and the patellar tendon during their mid term follow up period demonstrated excellent results. However, the final results during their last follow up showed no statistically significant difference between the two groups.

  • The customer satisfaction of WAP service greatly relies on the usability of the service due to the limited display size of a mobile phone and limitation in realizing UI (User Interface) for function keys, browser, and OS (operating system) Currently, a number of contents providers develop and deliver varying services, and thus, it is critical to control quality level of UI in consistent standards and manner. This study suggests usability index evaluation system to achieve consistent UI quality control of various WAP services. The system adopts both top-down and bottom-up approaches. The former concerns deriving UI design components and evaluation checklists for the WAP, based on the usability attributes and UI principles. The latter concerns deriving usability-related evaluation checklists from the established UI design features, and then grouping them from the viewpoint of usability principles and attributes. This bidirectional approach has two outstanding advantages: it allows thorough examination of potential elements that can cause usability problems from the standpoint of usability attributes, and also derives specific evaluation elements from the perspective of UI design components that are relevant to the real service environment. The evaluation system constitutes a hierarchical structure by networking usability attributes, UI guideline which indicates usability principles for each attribute, and usability evaluation checklist for each UI component that enables specific evaluation. Especially, each evaluation checklist contains concrete contents and format so that it can be readily marked in O/X. The score is based on the ratio of number of items that received positive answer to the number of total items. This enables a quantitative evaluation of the usability of mobile WAP service. The validity of the proposed evaluation system has been proved through comparative analysis with the real usability problems based on the user test. A software was developed that provides guideline for evaluation objects, criteria and examples for each checklist, and automatically calculates a score. The software was applied to evaluating and improving the real mobile WAP service.

  • This study started with the question, "Is the cost of landscape construction work in residential areas measured by public enterprises, 'in response to the needs of consumers?" The study analyzed whether the landscape construction expenditure is being introduced at an appropriate ratio according to the value the residents have regarding landscape elements. Following this, research was conducted for the purpose of providing basic data for improving the efficiency of formulating apartment landscape construction costs in the future. This research proceeded based on a questionnaire survey of residents of apartments, and the content of the questionnaire used frequency analysis and descriptive statistics research methods. To take a look at a comparative analysis of value recognition, in particular, a comparative analysis was performed based on the actual input cost based on the ratio of landscape elements by layer. Conclusions were found as follows: First, the degree of interest in the apartment landscape of the tenants was high, and the value of the landscape was high but realistic satisfaction appeared comparatively low. Second, the awareness of residents' values regarding landscape elements appeared to give "plantings" more value than "facilities". Thirdly, as a result of a mutual comparison between the values recognized by the resident regarding landscape elements and the construction input fee, depending on the landscape elements, it appeared that there is a difference in the ratio of up to 52 times from 1.25. Fourth, the fact that there is a difference in the relative proportion of value recognition and inputting construction cost indicates that it is not possible to respond to the needs of tenants during the construction cost development process. It also shows that the utility of inputting construction costs is low. Therefore, a macro-level examination such as reflecting the existing inflation rate is necessary to develop the efficient landscape construction cost of apartment such as the awareness of the value of the residents regarding landscape elements, out of the customary construction cost formulation method based on the microscopic dimensions of the consumer side.

  • Purpose: Our goal for this study was to prospectively evaluate the functional & structural outcomes, by means of CT arthroscopy, of arthroscopic double-row fixation for treating rotator cuff tear. We also attempted to determine the variants that affect the functional & structural outcomes. Materials and Methods: Twenty seven consecutive patients underwent arthroscopic rotator cuff repair with double-row fixation. The average age at the time of the operation was fifty six years. The preoperative and postoperative examinations consisted of determining the Constant score, the score for the visual analogue scale for pain, the UCLA score, the American Shoulder and Elbow Surgeons (ASES) score, as well as a full physical examination of the shoulder. Preoperative MR arthrography was used to evaluate the integrity and atrophy of the rotator cuff. We measured the intraoperative tear size in the sagittal and coronal planes. Postoperative CT arthrography was used at one year postoperatively to evaluate the integrity and atrophy of the repaired tendons and muscles. Results: Preoperative MR arthrography revealed an average 29.22 mm tear size in the sagittal plane and an average 22.72 mm tear size in the coronal plane. Twelve cases of supraspinatus muscle atrophy and two cases of infraspinatus atrophy were observed on the preoperative MR arthrography. The average clinical outcome scores all significantly improved at the time of follow-up. At a mean of one year postoperatively, CT arthrography revealed 48.1% of the shoulders had healed, 11.1% showed incomplete healing and 40.7% showed retear of the repaired tendon. Conclusion: Arthroscopic double-row repair can result in improved clinical outcomes and good patient satisfaction. However, the problems about how to enhance healing of the repaired tendon still remain.

  • This study was performed to investigate the performance state and improvement countermeasure of Primary Health care Posts(PHPs). The operation reports of PHPs(1996 330 PHPs, 1999 313 PHPs) located in Kyongsangbuk-Do and data collected by self-administered questionnaire survey of 280 community health practitioners(CHPs) were analyzed. The major results were as follows: Population per PHP in 1999 decreased in number compared with 1996. But population of the aged increased in number. The performance status of PHP in 1999 increased compared with 1996. A hundred forty one community health practitioners(50.4%) replied that the fiscal standing of PHP was good. Only 1.4% replied that the fiscal standing of PHP was difficult. For the degree of satisfaction in affairs, overall of community health practitioners felt proud. The degree of cooperation between PHP and public health institutions was high and the degree of cooperation of between PHP and private medical institutions was high. The degree of cooperation between PHP and Health Center was significantly different by age of CHP, the service period of CHP, and CHP's service period at present PHP. Over seventy percent of CHPs replied that they had cooperative relationship with operation council, village health workers, community organization. CHPs who drew up the paper on PHP's health activity plan were 96.4 % and only 11.4% of CHPs participated drawing up the report on the second community health plan. CHPs who grasped the blood pressure and smoking status of residents over 70% were 88.2%, 63.9% respectively and the grasp rate of blood pressure fur residents were significantly different according to age and educational level of CHP. CHPs received job education in addition continuous job education arid participated on research program in last 3 years were 27.5%, respectively. CHPs performed the return health program for residents in last 3years were 65.4%. Over 95% of CHPs replied that PHPs might be necessary and 53.9% of CHPs replied that the role of PHPs should be increased. CHPS indicated that major reasons of FHPs lockout were lack of understanding for PHP and administrative convenience, CHPs were officials in special government service governors intention of self-governing body. CHPs suggested number of population in health need such as the aged and patients with chronic disease, opinion of residents, population size, traffic situation and network in order as evaluation criteria for PHP and suggested results of health performance, degree of relationship with residents, results of medical examination anti treatment, ability for administration and affairs in order as evaluation criteria for CHP. CHPs replied that the important countermeasures for PHPs under standard were affairs improvement of PHPs and shifting of location to health weakness area in city. Over 50% of CHPs indicated that the most important thing for improvement of PHPs was affairs adjustment of CLIP. And CHPs suggested that health programs carried out in priority at PHP were management of diabetes mellitus and hypertention. home visiting health care, health care for the aged. The Affairs of BLIP should be adjusted to satisfy community health need and health programs such as management of diabetes mellitus and hypertention, home visiting health care, health care for the aged should be activated in order that PHPs become organization reflecting value system of primary health care.

  • With the MICE(Meeting, Incentive travel, Convention, Exhibition) industry coming into the spotlight, there has been a growing interest in the domestic exhibition industry. Accordingly, in Korea, various studies of the industry are being conducted to enhance exhibition performance as in the United States or Europe. Some studies are focusing particularly on analyzing visiting patterns of exhibition visitors using intelligent information technology in consideration of the variations in effects of watching exhibitions according to the exhibitory environment or technique, thereby understanding visitors and, furthermore, drawing the correlations between exhibiting businesses and improving exhibition performance. However, previous studies related to booth recommendation systems only discussed the accuracy of recommendation in the aspect of a system rather than determining changes in visitors' behavior or perception by recommendation. A booth recommendation system enables visitors to visit unplanned exhibition booths by recommending visitors suitable ones based on information about visitors' visits. Meanwhile, some visitors may be satisfied with their unplanned visits, while others may consider the recommending process to be cumbersome or obstructive to their free observation. In the latter case, the exhibition is likely to produce worse results compared to when visitors are allowed to freely observe the exhibition. Thus, in order to apply a booth recommendation system to exhibition halls, the factors affecting the performance of the system should be generally examined, and the effects of the system on visitors' unplanned visiting behavior should be carefully studied. As such, this study aims to determine the factors that affect the performance of a booth recommendation system by reviewing theories and literature and to examine the effects of visitors' perceived performance of the system on their satisfaction of unplanned behavior and intention to reuse the system. Toward this end, the unplanned behavior theory was adopted as the theoretical framework. Unplanned behavior can be defined as "behavior that is done by consumers without any prearranged plan". Thus far, consumers' unplanned behavior has been studied in various fields. The field of marketing, in particular, has focused on unplanned purchasing among various types of unplanned behavior, which has been often confused with impulsive purchasing. Nevertheless, the two are different from each other; while impulsive purchasing means strong, continuous urges to purchase things, unplanned purchasing is behavior with purchasing decisions that are made inside a store, not before going into one. In other words, all impulsive purchases are unplanned, but not all unplanned purchases are impulsive. Then why do consumers engage in unplanned behavior? Regarding this question, many scholars have made many suggestions, but there has been a consensus that it is because consumers have enough flexibility to change their plans in the middle instead of developing plans thoroughly. In other words, if unplanned behavior costs much, it will be difficult for consumers to change their prearranged plans. In the case of the exhibition hall examined in this study, visitors learn the programs of the hall and plan which booth to visit in advance. This is because it is practically impossible for visitors to visit all of the various booths that an exhibition operates due to their limited time. Therefore, if the booth recommendation system proposed in this study recommends visitors booths that they may like, they can change their plans and visit the recommended booths. Such visiting behavior can be regarded similarly to consumers' visit to a store or tourists' unplanned behavior in a tourist spot and can be understand in the same context as the recent increase in tourism consumers' unplanned behavior influenced by information devices. Thus, the following research model was established. This research model uses visitors' perceived performance of a booth recommendation system as the parameter, and the factors affecting the performance include trust in the system, exhibition visitors' knowledge levels, expected personalization of the system, and the system's threat to freedom. In addition, the causal relation between visitors' satisfaction of their perceived performance of the system and unplanned behavior and their intention to reuse the system was determined. While doing so, trust in the booth recommendation system consisted of 2nd order factors such as competence, benevolence, and integrity, while the other factors consisted of 1st order factors. In order to verify this model, a booth recommendation system was developed to be tested in 2011 DMC Culture Open, and 101 visitors were empirically studied and analyzed. The results are as follows. First, visitors' trust was the most important factor in the booth recommendation system, and the visitors who used the system perceived its performance as a success based on their trust. Second, visitors' knowledge levels also had significant effects on the performance of the system, which indicates that the performance of a recommendation system requires an advance understanding. In other words, visitors with higher levels of understanding of the exhibition hall learned better the usefulness of the booth recommendation system. Third, expected personalization did not have significant effects, which is a different result from previous studies' results. This is presumably because the booth recommendation system used in this study did not provide enough personalized services. Fourth, the recommendation information provided by the booth recommendation system was not considered to threaten or restrict one's freedom, which means it is valuable in terms of usefulness. Lastly, high performance of the booth recommendation system led to visitors' high satisfaction levels of unplanned behavior and intention to reuse the system. To sum up, in order to analyze the effects of a booth recommendation system on visitors' unplanned visits to a booth, empirical data were examined based on the unplanned behavior theory and, accordingly, useful suggestions for the establishment and design of future booth recommendation systems were made. In the future, further examination should be conducted through elaborate survey questions and survey objects.
