This study analyzed the influence of the quality of medicinal food on perceived values, repurchase intention and recommendation intention. The objective of this study is to suggest the efficient operating direction for specialized medicinal food restaurants to grow as an axis of the food service industry by showing the future direction of medicinal food and establishing marketing strategies to maintain/secure customers. From June 15th to July 2nd, 2009, the survey was conducted for the customers of medicinal food restaurants, located in Seoul and Gyeonggi-do. After distributing 250 copies of questionnaire, 195 of them were collected and total 192 were used for the analysis after excluding three copies due to lack of showing sincerity. The analysis results of this study can be summarized as follows. First, the quality of medicinal food was found to have a significant influence on 'functional value(t=5.519)' while having no influence on 'social value.' Second, the 'nutritional quality' of medicinal food was analyzed as having a significant influence on 'social value(t=10.954)' and 'functional value'(t=8.237).' Third, the 'medicinal quality' of medicinal food was analyzed as having no significant influence on 'social value(t=1.191)' and 'functional value(t=0.022).' Fourth, it was found that 'social value' had a significant influence on repurchase intention(t=9.743) and recommendation intention(t=9.154). Fifth, the functional value was analyzed as having a significant influence on repurchase intention(t=7.895) and recommendation intention(t=8.143). The results of the empirical analysis shown in this study properly support the theoretical standard system to achieve successful performance and useful information necessary for systematic operation of specialized medicinal food restaurants.

Objects : This study was carried out to investigate characteristics of patients who need hypnotics on the night before elective surgery as well as contributing variables for the necessity of hypnotics. Methods : After reviewing the clinical charts of patients who were scheduled to receive surgery by general anesthesia the following day, researchers had semi structural interviews with patients. In addition, Spielberger's State-Trait Anxiety Inventory(SSTAI), Beck Depression Inventory(BDI), Zung's Self-Rating Pain and Distress Scale(ZPDS), and Presleep and Postsleep Questionnaires were administered to patients. A total of 167 patients, who gave reliable information, were divided into two groups based on subjective judgement regarding the necessity for hypnotics on the night before surgery; 29 eligibles for hypnotics and 138 non-eligibles for hypnotics. Demographic and clinical characteristics of patients, some possible factors affecting sleep, psychological characteristics of patients and daytime status and nighttime sleep before surgery were compared between the two groups. In addition, discriminant function analysis was done to find the variables which would best discriminate among patients who differ in terms of necessity for hypnotics on the night before surgery. Results : There was no difference in demographic and clinical characteristics between the two groups; however, the satisfaction level with ward environment was significantly lower in the eligible group for hypnotics than the non-eligible group. Psychologically, the eligible group for hypnotics, compared to the non-eligible group, showed significantly more severe depression, pain, and distress; whereas anxiety level was not different between the two groups. For nighttime sleep before surgery, the eligible group for hypnotics, compared to the non-eligible group, expected poorer sleep before retiring and in fact, reported poorer sleep the following morning. In discriminant function analysis, 'expectation for sleep' and 'pain and distress' were the most potent contributors to discriminate the necessity of hypnotics. Conclusion : For the improvement of the patient's sleep on the night before elective surgery, giving hypnotics and/or analgesics should be determined by patient's opinion about the necessity of the drugs rather than by the therapist's own judgement or any other objective indices.

Objective: Birth sex ratio (BSR) with human IVF-ET program is an interesting subject of social and scientific issue but very little information is available in Korea. This study was performed to assess the BSR with IVF-ET and to suggest the effective factors on the BSR. Methods: The national data from 1991~2008 were obtained from governmental Statistics Korea and the delivery data of human IVF-ET program on 2007 and 2008 were provided from the Ministry for Health, Welfare and Family Affairs. The BSR were statistically analyzed according to methods of IVF and to transferred embryos from fresh or frozen-thawed cycles. Results: The BSRs of Korean populations were over 1.10 up to 2002, and then it declined and maintained to 1.06 as balance BSR on 2007 and 2008. In human IVF-ET program, the BSRs were 1.07 on 2007 and 1.06 on 2008, respectively. Conventional IVF on 2008 showed the highest BSR as 1.10, and ICSI the lowest on 2008 as 1.01. There was no significant difference of BSRs related to the methods of in vitro fertilization and the feature of transferred embryos. Conclusion: The BSR of Korea showed 1.06~1.07 as normal and balanced state on 2007 and 2008 both general populations and human IVF-ET program. To the best of our knowledge, this is the first study to evaluate the BSR of human IVF-ET in Korea. There is a need to expand the further studies for national statistics and influencing factors on the BSR with IVF-ET.

Human health is an integral part of experience in the process of Human Becoming. Through continual interaction with the environment human beings freely choose experience and develop as responsible beings. The process of the health experience of patient with terminal cancer is a unique. he objective of this study is to understand the lived experience of patients with terminal cancer in order to provide basic information for nursing care in the clinical setting and to develop a theoretical background for clinical practice. This study is to de-scribe and define the lived experience of patients with terminal cancer in order to provide a foundation for nursing research and education. Data collection has been done between December 1993 and November 1994. The subjects included five persons -four females and one male : one who was in her sixties, one in his fifties, two in their forties, and one who was in her thirties. The researcher has met with these patients 35 times, but at eight times the patient was in a stuporous condition and not able to participate, so these were not included in the data analysis. Parse's "Human Becoming Methodology", an existential phenomenological research methodology is used for this study. Data has been collected using he dialogical engagement process of "I and You", the participant researcher and the participant subject. Dialogical engagement was discontinued when the data was theoretically saturated. Data was analyzed using the extraction - synthesis and heuristic interpretation. The criteria of Guba and Lincoln(1985). and Sandelo wski(1986) : credibility, auditability, fitness and objectivity were used to test the validity and reliability of the data. The following is a description of the structure of the lived experience of patients with terminal cancer as defined by this study : 1. Structure : 1) Suffering through the reminiscence of past experience 2) The appearance of complex emotions related to life and connectedness 3) The increasing importance of significant people and of the Absolute Being 4) The increasing realization of the importance of health and belief 5) Desire for a return to health and a peaceful life or for acceptance of dying and a comfortable death In summary the structure of the lived experience of these patients can be said to be : suffering comes through reminiscence of past experience, and there are complex emotions related to life and connectedness. Significant people and the Absolute Being become increasingly important along with a realization of the importance of health and faith. And finally there is a desire for either a return to health and a peaceful life or for the acceptance of dying and a comfortable death. 2. Heuristic Interpretation : Using Parse's Human Becoming Methodology, the structure of the lived experience of patients with terminal cancer identified in this research is interpreted as. The lived experience of patients with terminal cancer involves the solving of past conflicts, and the experience of the healing and valuing of sorrow and pain. Through the relation of life and health, and the complex emotions that arise, the lived experience of revealing - concealing is of paradoxical emotions. The increasing importance of significant others and of the Absolute Being shows Connecting and Separating an on- going process of nearness and farness. Revision of thoughts about health and faith is interpreted as transforming and desire for restoration to health and a peaceful life or acceptance of dying and a cowfortable death, as powering. In summary, it is possible to see, in the lived experience of patients with terminal cancer, the relationship of the five concepts of Parse's theory : valuing, revealing -concealing, connecting-separating, transforming, and powering. From Parse's theory, the results of this study show that meaning is related to valuing, rhythmicity to revealing-concealing and connect-ing-separating, and cotranscendence to transforming and powering.

Objective: This study compared the bone thickness of the palate between lateral cephalogram and 3D model measurements. Methods: The subjects consisted of 30 adults (15 men,15 women) with a normal skeletal pattern and occlusion. The CT images were transformed to a 3D model, and were compared with the cephalometric image. Descriptive statistics for each variable were calculated. Results: In the 3D CT model, the mid-palatal area was the thickest part. It became thinner as the palate tapered laterally. In the male group, the thinnest portion was positioned 6 mm away from the mid-palate, while in the female group the thinnest portion was 8mm away from the mid-palate. Correlation analysis between the lateral cephalometric and 3D CT model revealed a significant correlation except in the mid palatal area and the area 2 mm lateral to the mid-palate in men, whereas there was a significant relationship in every area in the women. In both men and women, the highest correlation appeared in the area 8 mm lateral to the mid palate. Conclusions: Using regression analysis, an actual prediction of the bone thickness between the measured bone thickness of the lateral cephalometric radiograph and 3D model was made. This will provide useful information for mini-implant length selection when inserting into the palate.

Objective: The purpose of this study is to examine the effects of oral exercise on oral function and denture satisfaction of the elderly using dentures. Methods: The study was conducted with targets of the elderly in the 13 senior community centers in Cheongsong-gun, Gyeongsangbuk-do from September 2013 to April 2014. The study subjects were divided into two groups, the intervention group provided with 8 week oral exercise program and the control group without exercise. The data on oral function, denture satisfaction and oral health related quality of life (OHIP-14) were analyzed among the 79 subjects from the intervention group and the 71 subjects from the control group. Results: For oral function, salivary flow rate, mouth opening, pronunciation and salty taste were significantly improved in the intervention group (p<0.01). There were significant differences in salivary flow rate, mouth opening, pronunciation and salty taste between the two groups (p<0.01). For denture satisfaction, there were significant differences in masticatory function, fixing function, general treatment satisfaction and total denture satisfaction between the two groups (p<0.05). There were significant differences between the two groups in the total points of oral health related quality of life. Conclusion: Oral exercise was effective in improving oral function and denture satisfaction of the elderly using dentures. To improve oral health related quality of life of the elderly further researches and programs will be necessary.

Breathing is the voice's driving force and also acts as a regulator of larynx function and efficiency. Respiratory distress is a side effect of general anesthesia in thyroid surgery. Therefore, this study's objective was to provide practical and complementary information for voice recovery after thyroid surgery, based on aerodynamic evaluation pre- and post-thyroidectomy. From May 2014 to July 2015, aerodynamic evaluations were performed on 34 female patients diagnosed with thyroid papillary cancer one week before surgery (PRE), one month after surgery (P1), and three months after surgery (P3). The Phonatory Aerodynamic System (model 6600, KayPENTAX, USA) was employed for this purpose, and a total of 29 analysis parameters were selected. The results showed statistically significant differences in peak expiratory airflow (p=0.004), mean pitch (p<0.01), expiration airflow duration (p=0.001), and expiratory volume (p=0.018), based on time factors. In the comparison of time factors, peak expiratory airflow and mean pitch parameters were different in PRE-P1 and PRE-P3. Expiration airflow duration and expiratory volume parameters were different in PRE-P3 and P1-P3. The interaction effect of time and surgical range was significant only for expiratory volume (p=0.024). Female patients who undergo thyroidectomy require post-operative breathing training, and exhalation improvement is considered to reflect a positive lifestyle after surgery.

Background: In the pathogenesis of acute lung injury induced by lipopolysaccharide(LPS), oxygen radiclls are known to be involved in one part. Superoxide dismutase(SOD) protects oxygen radical-induced tissue damage by dismutating superoxide to hydrogen peroxide. In eukaryotic cells, two forms of SOD exist intracellularly as a cytosolic, dimeric copper/zinc-containing SOD(CuZnSOD) and a mitochondrial, tetrameric manganese-containing SOD(MnSOD). But there has been little information about SOD gene expression and its regulation in pulmonary alveolar macrophages(PAMs). The objective of this study is to evaluate the SOD gene expression induced by LPS and its regulation in PAMs of rat. Method: In Sprague-Dawley rats, PAMs obtained by broncholaveolar lavage were purified by adherence to plastic plate. To study the effect of LPS on the SOD gene expression of PAMs, they were stimulated with different doses of LPS($0.01{\mu}g/ml{\sim}10{\mu}g/ml$) and for different intervals(0, 2, 4, 8, 24hrs). Also for evaluating the level of SOD gene regulation actinomycin D(AD) or cycloheximide(CHX) were added respectively. To assess whether LPS altered SOD mRNA stability, the rate of mRNA decay was determined in control group and LPS-treated group. Total cellular RNA extraction by guanidinium thiocyanate/phenolfchlorofonn method and Northern blot analysis by using a $^{32}P$-labelled rat MnSOD and CuZnSOD cDNAs were performed. Results: The expression of mRNA in MnSOD increased dose-dependently, but not in CuZnSOD. MnSOD mRNA expression peaked at 8 hours after LPS treatment. Upregulation of MnSOD mRNA expression induced by LPS was suppressed by adding AD or CHX respectively. MnSOD mRNA stability was not altered by LPS. Conclusion: These findings show that PAMs of rat could be an important source of SOD in response to LPS, and suggest that their MnSOD mRNA expression may be regulated transcriptionally and require de novo protein synthesis without affecting mRNA stability.

Objective: To reduce urinary side effects in prostate cancer patients receiving radiation, patients were asked to drink certain amount of water to maintain bladder volume constant and the bladder volumes were measured weekly using ultrasound scanner. Materials and Methods: Twenty-six patients with prostate cancer who received radiation between December 2002 and August 2007 were enrolled in this study. Thirteen patients were enrolled in experimental group. These patients were asked to drink 450 cc of water, one hour prior to simulation, CT scan, and treatment. The other thirteen patients were given no information about bladder filing. Bladder, prostate, and rectum were contoured on CT and volumes were calculated. 3D conformal treatment planning was performed and effective volumes of bladder were calculated when a prescription dose of 70.2 Gy was delivered. For the patients in experimental group, bladder volumes were measured weekly using ultrasound scanner for 6-8 weeks and the bladder volume variations were analyzed. Results: Average bladder volumes and standard deviations obtained at CT scanning were $283.5{\pm}114.0\;cc$ (40%) and $181.2{\pm}120.1\;cc$ (66%) in experimental and control groups, respectively. Although it was not statistically significant, there was correlation between the bladder volumes measured from CT and ultrasound. The volumes measured using ultrasound scanner were 62% lower than the volumes using CT images on average. There was significant variations in volumes measured weekly for 6-8 weeks. It ranged between 33 - 75 %. Conclusion: Our results showed that it is possible to obtain larger bladder volume if they are asked to drink certain amount of water prior to CT scan. However, patients were unable to maintain constant bladder volumes over the 6-8 weeks of treatment period although they were asked to drink constant amount of water.
