Purpose: The purpose of tile study was to identify types of care needs of hospice patients and those from the family caregivers' perspective and to compare these two groups in reporting patients' care needs through Q-methodology. Methods: Twenty three Q-statements concerning care needs were selected through in-depth interviews of hospice patients. Data were collected from 20 hospice patients as well as 20 family caregivers respectively by sorting 23 Q-statements into 9 points standard. Data analysis was performed by using PC QUANL program. Results: Principal component analysis identified four types of care needs of the hospice patients. Overall, the accuracy of family caregiver reports was 48% in all types of care needs. Type 1 was named 'physical care needs type' for those whose greatest need was physical care to be free of pain and comfortable. The accuracy in Type 1 was 62.5%. Type 2 was named 'emotional care needs type' for those who would like to share love and intimacy with their family members. The accuracy in Type 2 was 20%. Type 3 was named 'spiritual care needs type' for those who would like to receive forgiveness from their God and prayers and visitation of clergy. The accuracy in Type 3 was 60%. Type 4 was named 'social care needs type' for those who would like to complete their ongoing work and to give service to others. The accuracy in Type 4 was 50%. Conclusion: There was a great difference between hospice patients and the family caregivers in reporting patients' care needs. Thus, hospice nurses need to educate family caregivers to more accurately assess patients' care needs.

In order to clarify the Gosambaeksunpibokhap-bang(GBBB)'s therapeutic possibility on atopic dermatitis (AD), influences of GBBB on the changes of various immune-related factors and histological changes in NC/Nga mice were evaluated. Experimental results are as follows. Sign of recovery from AD was observed in GBBB treated group with naked eye test. The ratio of white blood cells, neutrophil, lymphocytes, monocyte in blood were decreased to 54%, 63%, 57% and 86% respectively in the GBBB group. IL-4, IL-5, IL-13, Histamine and IgE were significantly decreased to 40%, 80%, 62%, 61% and 57% respectively in the GBBB group. H&E staining showed thickness of epidermis and dermis were decreased by GBBB and inhibited the infiltration of lymphocytes. On the basis of these results, GBBB was confirmed that the possibility as an AD treatment applied externally to the skin. In the further study, immune control mechanism of GBBB will be demonstrated through the additional molecular biological research.

This study has been conducted to see influence of fibroid hepatic tissue on alpha-tocopherol and its histologic changes. Experimental groups were divided into 3 groups, one where fibrosis was caused by carbon tetrachloride and the other where alpha-tocopherol and carbon tetrachloride were administered together and another normal group. Results of test showed fibrosis reaction is weak compared to the group administered with carbon tetrachloride in the group administered with alpha-tocopherol. In conclusion, we could observe proliferation of collagen fibers through Hematoxylin&Eosin and Massom trichrom dye and increase in ALT, AST, ALP in fibroid hepatic tissues, indicating convergence anti-oxidation reaction by changes of alpha-tocopherol intake. Thus, it is considered that we can expect to utilize alpha-tocopherol as secondary treatment and find clinical meanings of diagnosis on hepatic diseases through results of this study.

The effects of peritoneal exudate cells(PEC) and sera of athymic nude and DS mice infected with Clonorchis sinensis metacercariae or sensitized by injection of metabolic products into footpad on transfer of immunity against the fluke to the syngeneic mice were studied. There was no significant difference in eggs per gram pattern between the sensitized and control groups, and between nude and DS mice. However, the worm burdens were slightly greater in nude mice than in DS mice. Also, a few plaque forming cells were found in only DS mice given PEC and serum from Group II DS mice. In the light of these results, it is likely that PEC and sera of nude or DS mice which are deficient, at least partially, in the cellular immune system are unable to transfer immunity against C. sinensis to syngeneic recipients.

The stabilized $ClO_2$ gas has been used for many years by the food industry as a strong oxidizing and sanitizing agent that has broad and high biocidal effectiveness. Therefore, "stabilized $ClO_2$" gas may be used in fields of disinfectant and sterilization. But, there have been few studies on the decomposition-inhibition effect of stabilized $ClO_2$ gas with passage of time. The main purpose of this study was to examine the decomposition-inhibition effect of stabilized $ClO_2$ gas and the morphological change of kidney by measuring of the light and electron microscope. Sprague-Dawley (SD) rats weighting from 230 gm to 250 gm were used as experimental animals. Under ether anesthesia, the right kidney of rat was obtained. Put each sample in $37^{\circ}C$ and humidity $80{\pm}5%$ incubator, we obtained each sample after 0 day, 1 day, 2 days, 3 days, 4 days and 5 days. We proceeded the observation of light and electron microscope. The results obtained in this study reveal that stabilized $ClO_2$ gas is an effective decomposition inhibitor until 2 days that was conducted at $37^{\circ}C$ and humidity $80{\pm}5%$ conditions.

The purpose of this study was to identify the correlation and level of Body Mass Index, Body Shape Dissatisfaction, Eating Behavior in college students. Methods: A total of 383 students were asked. The survey was analyzed by SPSS Win 21.0 program. 293 were female students and most of the students were normal in BMI(58.2%), and underweight students were the next(14.9%). There were positive correlation between body shape non satisfication and eating behavior and BMI(r=.587, p=.000; r=.174, p=.001), and negative correlation between body shape non satisfication and age and sleeping time. According to BMI the body shape non satisfication was different in normal and 1 stage obesity students. and 2 stage obesity and under weight students (F=2.993, p=.019;F=2.993, p=.109). As a result of this study, students with body mass index overweight have low body satisfaction, so it is necessary to educate the right dietary exercise therapy for weight management. And even underweight groups should be mediated so that they undergo normal diet behaviors, rather than restrained dietary behaviors, to maintain health.

Purpose: The physical and optical characteristics of hydrophilic tinted contact lens containing titanium silicon oxide nanoparticles and the basic hydrogel contact lens material containing 4-iodoaniline were examined. In this study, the utility of titanium silicon oxide nanoparticles as a UV-blocking material for ophthalmologic devices were investigated by measuring the UV transmittance of the produced polymer. Also, titanium silicon oxide nanoparticles only without the addition of 4-iodoaniline in primary contact lens materials by copolymerizing two groups were compared. Methods: For manufacturing hydrogel lens, HEMA, MA, MMA, 4-iodoaniline and a cross-linker EGDMA were copolymerized in the presence of AIBN as an initiator. Also, the titanium silicon oxide nanoparticles was used as additive. After polymerization the physical properties such as water content, refractive index, contact angle and spectral transmittance of produced contact lenses were measured. Results: Measurement of the physical properties of the copolymerized material showed that the water content, refractive index, UV-B transmittance and contact angle were in the range of 35.01~38.60%, 1.4350~1.4418, $34.15{\sim}57.25^{\circ}$ and 1.0~10.0%, respectively. Titanium silicon oxide nanoparticles is not used as an additive in the experimental group, the results of the measurement showed that the water content, refractive index, contan angle and UV-B transmittance of the hydrogel lens polymer was 34.00~36.80%, 1.4378~1.4420, $40.15{\sim}60.16^{\circ}$ and 1.8~25.0%, respectively. Conclusions: Also, the transmittance for UV light was reduced significantly in combinations containing titanium oxide nanoparticles.

The purpose of this study was to investigate the pretreatment and posttreatment dentofacial characteristics of non-extraction patients with Class I malocclusion. And to compare this result with matched non-orthodontic normal occlusion and Class I premolar extraction patients. Such comparison might help identify morphologic characteristics of the non-extraction patients. Initial and final cephalometric evaluation were compared in a sample of 22 patients with Class I malocclusions treated in non-extraction manner with edgewise appliance and MEAW The mean age of the total population was 14 years 9 months and the average treatment time was 2 years 8 months. 32 landmarks were located and digitized on each cephalogram. From these landmarks, 24 linear and angular dimension were obtained. Student's t-test were used to compare the pretreatment - posttreatment results, Nonextraction - Normal groups, and nonextraction Extraction groups. Significance was predetermined at $p{\leq}0.05$. The results were as follows. 1. Before treatment, the mean value of the $ODI\;was\;69.9^{\circ},\;APDI\;was\;82.1^{\circ},\;CF\;was\;152^{\circ},\;EI\;was\;152^{\circ}$ in the non-extraction groups. 2. The skeletal pattern of the non-extraction groups were similar with non-orthodontic normal groupsr, but the non-extraction groups had larger interincisal angle. 3. Comparison between groups treated with and without extraction indicated at pretreatment, the extraction groups had more protrusive lips, smaller interincisal angle, and EI. 4. After treatment, there was no significant changes in the skeletal pattern of the non-extraction groups, but uprighting of the maxillary and mandibular first molar and decrease of the interincisal angle were seen.
