Purpose: This study investigated the effects that music therapy by self-selected music listening has on the affect and stress relief in adult patients who have been diagnosed with terminal cancer by pain level. Methods: Participants were 20 terminally ill cancer patients who were over 18 years old and were admitted to the hospice and palliative care unit of a local hospital. At the beginning of each session, participants selected music of their choice. Each participant had a total of six 30-minute music listening sessions. Participants were grouped into two according to their self-rated perceived pain scores on the visual analogue scale and numeric rated score: 5 and above and less than 5. Each participant completed a questionnaire on their affect state before and after each session and a questionnaire on their stress level before the first session and after the last session. Further analysis was performed to compare differences between the two groups according to pain level. Results: There were significant differences in patients' affect before and after each session (P<0.001) and stress level before and after the therapy (P=0.001). Conclusion: In this study, self-selected music listening had positive effects on terminal cancer patients' affect and stress regardless of perceived pain level. Therefore, self-selected music listening can be used as an appropriate intervention to improve affect and reduce stress in terminal cancer patients in the hospice and palliative care unit.

Emulsions were prepared with the inversion emulsification method which adopted the agent-in-oil method-dissolving the mixed surfactants composed of the glycerin monostearate, polyoxyethylene(100) monostearate, and polyoxyethylene(20) sorbitan monostearate into mixtures of liquid paraffin and beeswax, and adding the aqueous solution of propylene glycol, gradually-and then their phases and viscosities behaviors in the emulsifying process were investigated. The fine and homogeneous o/w emulsions were formed in the HLB region (HLB 10.1~12.3), showing liquid crystalline phase and white gel phase in the emulsifying process. The phase inversion steps in the emulsifying process appeared as follows, i.e., oil continuous phase${\rightarrow}$liquid crystalline phase${\rightarrow}$white gel phase${\rightarrow}$o/w emulsion. Shear rate-shear stress curves of the prepared emulsions had the yield values which pointed out the existence of inner structure between emulsion particles, and the hysteresis loop which showed that the inner structure wasbroken irreversibly by the shear. The area of hystersis loop, an index of breakdown of inner structure, was increased with the decreasing of the HLB value of emulsifier, Shear time-shear stress curves showed the time dependence of plastic viscosity, and the relaxation time in time thinning behavior(${\lambda}$) indicated that the stability of emulsions prepared with the inversion emulsification method was decreased with the increasing of HLB values of emulsifier and was higher than that of emulsions prepared by homomixer.

This study aimed to assess the influence of nicotine dependence with satisfaction of basic psychological needs, social support, attitude on smoking among middle school students. From Sep, 2015 to Nov, 2015, participants included 150 middle school students from D city and K province in Korea. Data for basic psychological needs, social support, attitude on smoking and nicotine dependence were collected through a self-reported questionnaire and were analyzed with independent t-test and analysis of variance, Pearson's correlation analysis, and multiple linear regression analysis. This study shows negative correlations between nicotine dependence and satisfaction of basic psychological needs(r=-.221, P=.008), competency(r=-.194, P=.021), relatedness(r=-.219, P=.009). The variables predicting nicotine dependence were satisfaction of basic psychological needs(${\beta}=.221$, p=.008). These variables accounted for 42% of the variance of nicotine dependence in smoking middle school students. Our results indicated that it is necessary to increase basic psychological needs to decrease nicotine dependence. Therefore we should develop programs in order to increase satisfaction of basic psychological needs.

The purpose of this study was to examine the effects of a physical activity program on body composition, depression and risk factors of dementia in elderly women. Subjects were 40 women aged 65~75 years, classified into two groups (experiment group 20, control group 20). The factors measured in this study were body composition (weight, percent body fat, body mass index, body fluid), depression (BDI score) and risk factors of dementia (K-MMSE, LDL-C, HDL-C, insulin, ${\beta}$-amyloid, DHEAs) at 12 and 24 weeks before and after the program. Subjects of experiment group participated in a 24 week physical activity program (45~60 min, 3~4 day per weeks). Data were analyzed by repeated ANOVA method of SPSS, with accepting levels for all significances above ${\alpha}$=0.05. The results of this study were as follows. In body composition, the experiment group showed significant differences in the weight, percent body fat and body mass index compared to the control group. In depression score, the experiment group showed no significant differences regarding BDI score level compared to the control group. In risk factors for dementia, the experiment group showed significant differences in levels of K-MMSE, LDL-C, HDL-C, insulin, ${\beta}$-amyloid, and DHEAs compared to the control group. This study showed that a 24 week physical activity program had positive effects on almost all of the factors evaluated in elderly women, and that elderly women who did not participate in the program experiences no such positive effects. Therefore, regular participation in a physical activity program could be advocated as one strategy to enhance body fat, depression, and risk factors of dementia and may result in improving risk for diseases of age in elderly women.

Isopropyl alcohol extracted filefish protein concentrate (FPC) and NaOH hydrolyzed filefish protein isolate (FPI) were used for the investigation on the effect of processing conditions on the molecular distribution and functional properties. The molecular distribution of FPC on polyacrylamide gel showed a resemblance to that of fish muscle, but that of alkaline hydrolyzed FPI showed the severe degradation of protein. The content of several amino acids in FPI were lower than those of FPC. The pepsin digestibility of the FPC dried at high temperature was relatively high. FPC didn't exhibit a significant difference in nitrogen solubility at the pH range of 3.0-9.0, while FPI showed a wide difference with the pH change. FPI was more suspensible and rehydrated in water than FPC. Although the aeration capacity of FPI was very low, foam viscosity was higher than that of FPC. In contrast with aeration capacity, FPI presented higher emulsion capacity and lower emulsion viscosity than FPC. The size of fat globule in the emulsion of FPC was larger than that of FPI. In general, most functional properties decreased with the increment in drying temperature, except water holding capacity.

This study aims to analyze the satisfaction of seniors living in Cheonan City downtown as to their residential environment. Also, this study intends to identify which factors should be improved first to make downtown a favorable residential area. To that end, 'social indicators of Chungnam' was used. The collected data was analyzed through a statistical analysis method using ANOVA (analysis of variance) and a cluster analysis. It led to the following findings. First, 6.9% of the elderly residents expressed their wish to move from their downtown residence. Thus, the majority of the residents do not want to move. Second, the satisfaction of the elderly residents in their downtown residence scored 6.09. The score is higher than those of other regions. Thus, it is highly possible to develop downtown into a senior-friendly area. Third, as for satisfaction in downtown residence, it was higher among the following groups: men; those with high school or higher level of education; those earning at least a million won a month; family of one generation. Fourth, satisfaction in the following factors was relatively low: culture and education; interaction with neighbors and trust in them; car accidents. Thus, those factors should be improved for downtown residents. Above all, community-faced facilities should be expanded to increase exchanges with neighbors and trust in them. To attract women dissatisfied with downtown residence. it is imperative to increase daily safety by reducing car accidents and crime.

Purpose: This study evaluated the effect of loss of interproximal papilla, creating an undercut, on the accuracy of impression materials. Materials and methods: Two addition type silicone impression materials ($Extrude^{(R)}$ Speed Wash, $Imprint^{TM}$ II Quick Step Light Body) and one alginate impression material (Cavex Impressional) were used to make impressions of a maxillary master model simulating clinical conditions with or without interproximal papilla. Stone was poured in the impressions and working casts were fabricated. A total of 6 groups with 6 working casts in each group were scanned using 3-dimensional optical scanner. The accuracy of the impressions was assessed by measuring the dimensional changes (${\Delta}I$ (%)) of 6 distances on working casts compared to a master model with a 3-dimensional digitizing and inspection software. The data were analyzed by two-way ANOVA (P<.05). Results: Three of 6 distances showed statistically significant differences among the impression materials. Only 1 of 6 distances in alginate impression showed a statistically significant difference between casts with and without interproximal papilla (P=.047). Conclusion: The presence of undercut due to loss of interproximal papilla did not significantly influence the dimensional accuracy of addition type silicone and alginate impression materials.

The installation of an implant in the distal extension area to assist a partial dentrue (IARPD) was used carefully in clinical situations. The purpose of this review on the IARPD is describing the concept, clinical results and guidelines of IARPD. For the review, a literature search was performed using the PubMed. The data from the literature suggest that the placement of the implants could improve function and patient satisfaction. In addition, IARPD reduced the residual ridge resorption. Longer and wider implant should be placed. Less than $15^{\circ}$ angulation may be not harmful. To prevent the loosening of the abutment, modified abutment or resilient attachment should be used. However, the connection method between the clasp retention and IARPD should be considered for long time success. Moreover, longitudinal clinical studies are required for evaluation of IARPD.
