Objectives: The purpose of this study is to develop a program of group psychotherapy named "the promotion of hope program (PHP)" that will provide effective emotional support for cancer patients. Methods: In order to develop a group counseling program for cancer patients, this study utilized reality therapy based on Oriental medicine theory which is the mind affect the body. We established four steps for making positive changes to individual behavior: creating soil for hope, watering hope, sprouting hope, and the blossoming flower of hope. To verify the effectiveness of the program, we conducted a comparative clinical trial. Patients were divided into two groups by unrestricted randomization: the intervention group (n=20) and the control group (n=17). The members of each group did not exceed seven patients. We divided the trial period into three sections. The intervention group received group psychotherapy twice a week for 4 weeks. The control group watched hope-related videos and talked about members for two hours each week for four weeks. We evaluated the scale of anxiety and depression, self-esteem, and hope, both before and after the examination. Results: PHP decreased the level of anxiety and depression in the intervention group (1.21 vs. 0.75, p<0.01). PHP also improved the level of both self esteem (2.80 vs. 3.34, p<0.01) and hope (2.69 vs. 3.23, p<0.01). In contrast, the control group showed no interval change at any point in time. Conclusion: Following the above results, PHP can be seen as an effective program for helping cancer patients to increase positive emotions and behaviors while reducing negative thoughts.

Objectives: This study was conducted to examine the effectiveness in oral health promotion through oral health education for freshmen students of the dental hygiene department. Methods: To verify its effectiveness, research was conducted on 74 freshmen of the dental hygiene department by the evaluation of DMFT index, PHP index, and Cariview test (2015-2016). Results: The analysis of the test results using Cariview equipment shows a categorization of low risk group consisting of 10 students (13.5%), middle risk group consisting of 47 students (63.5%), and a high risk group consisting of 17 students (22.9%). DT index according to the number of daily tooth brushing by <2 is DT index average score higher and in such a case, statistics are considered meaningful (p<0.01). Oral health state at DMFT index of low risk group according to Cariview risk group for an analysis is lower than both the middle risk group and the high risk group (p<0.001). Conclusions: A review of the effect of the promotion of oral health through oral health education on the behavior change rather than of Cariview test and value of dental plaque through tooth brushing method was conducted.

DHP mining association rules algorithm maintains previously independent direct hash table to reduce the sire of hash tree containing the frequency number of each candidate large itemset. It performs pruning by using the direct hash table when the hash tree is constructed. The mort large the size of direct hash table increases, the higher the effort of pruning becomes. Especially, the effect of pruning in phase 2 which generate 2-large itemsets is so high that it dominates the overall performance of DHP algorithm. So, following the speedy trends of producing VLM(Very Large Memory) systems, extreme increment of direct hash table size is being tried and one of those trials is perfect hash table in phase 2. In case of using perfect hash table in phase 2, we found that some rearrangement of DHP algorithm got about 20% performance improvement compared to simply ｜H$_2$｜ reconfigured DHP algorithm. In this paper, we examine the feasibility of perfect hash table in phase 2 and propose PHP algorithm, a rearranged DHP algorithm, which uses the characteristics of perfect hash table sufficiently, then make an analysis on the results in experimental environment.

The purpose of this study was to examine the correlation of oral health behavior, oral health state and PHP in an effort to facilitate the promotion of oral health and improve oral health care. The subjects in this study were patients who got a scaling at the oral hygiene practice lab in the department of dental hygiene in S college dental clinic from September 5 to December 1, 2007. The collected data were analyzed with SPSS WIN 12.0 program. The findings of the study were as follows: 1. The younger patients had a smaller number of FT index, and the older patients excelled the younger ones in oral health behavior involving the use of oral hygiene supplies, regular visit to dental clinics and dietary control. 2. The patients got 2.62 out of possible five points on oral health behavior, which indicated that their oral health behavior wasn't good enough. Those whose oral health behavior was better had a smaller number of DT index and a larger number of FT index. A better oral health behavior led to a lower PHP index. 3. There was a negative(-) interrelationship between oral health behavior and DT index, and oral health behavior had a positive(+) correlation with FT index. The oral health behavior had a negative(-) correlation to PHP index, which showed that a better oral health behavior led to a lower PHP index. The above-mentioned findings seem to suggest that oral health behavior is one of integral factors to affect oral health status and PHP index, and the kind of oral health education that could change oral health care attitude should be provided during scaling practice after grasping the actual oral health behavior of patients.

Objectives : This study is to examine the effectiveness in the oral health promotion through the oral health education for high school students. In adolescence, there seems to be the high incidences of dental caries, gingivitis and periodontal diseases. Concerning preventing all such outbreaks, this study focuses on applying the oral health education to their health education, and on analyzing its effectiveness. Methods : To verify its effectiveness, this research administered 85 students of both genders of a certain high school in Seoul during May-October 2010, followed by the evaluation of DMFT, S-PHP, and CPITN. Results : First, the oral health promotion through the education was statistically significant in the permanent effects of index (FT index). Second, the effect of S-PHP index gradually decreased in statistics from the first to the fifth session, but, after five months ever since the education, it seemed relatively higher in the next sessions. Third, the changing in the level of CPITN decreased continuously as the students received the education repeatedly, but there is no significant difference in statistics for each session. Conclusions : For the oral health promotion in the high school students, the education ought to be focused on the behavior-change objectives rather than on the knowledge-based objectives. The repeated education for tooth-brushing instruction should be stressed for preventing from returning to the old bad behaviors.

To prove pseudo-homopolymerization(PHP) method indirectly for general system which includes more than one growing radicals per particle, Mayo-Lewis equation of bulk copolymer system was derived form probability equation about instantaneous copolymer composition of emulsion copolymer system during interval II. From Extended Smith-Ewart equation proposed by Ballard et al. in emulsion copolymerization, exact solution was obtained for 0-1 system (i.e., the system containing no more than one growing radical per particle). From the exact solution, average number of radicals per particle and instantaneous copolymer composition were predicted to reach the steady state which a few minutes. So the reliability of this approximation method could by proved directly for 0-1 system. Styrene-butadiene(St-Bu) and Styrene-methyl methacrylate (St-MMA) system were used for model calculations.

This paper provides an overview of the experiences of the people's housing process (PHP) in South Africa. The discussion is done against the backdrop of the different outcomes of the government public housing provision initiative, commonly known as the Reconstruction and Development Programme (RDP) that directly produced more than three million subsidized housing to formerly segregated and disadvantaged populations. Notwithstanding the huge success in providing the much needed accommodation to such previously marginalized communities, the over-reliance on direct provision has the PHP ostensibly less impactful in housing delivery. Against the backdrop of the soaring housing backlogs, concerns with housing quality and the financial difficulties as well as the shrinking fiscal space; the article recommends improved support of the PHP. This can be achieved by the adoption of innovations that make land and minimal infrastructure and services available to the urban poor and to support their initiatives of self-building.

Ammonium polyphosphate-polyurethane foam composite (APP-PUF) was prepared from poly(adipate)diol/ammonium polyphosphate composite (f = 2), polyether polyol (f = 4.6), and PMDI (f = 2.5). As a blowing agent, $H_2O$ was used at various concentrations. The thermal decomposition behavior, morphology, closed-cell content, and density of APP-PUF were characterized. At the $H_2O$ concentrations lower than 3.5 php, the cell size of pure polyurethane foams (PUF) and APP-PUFs were close each other. As the $H_2O$ concentration became greater than 5.0 php, the cell size of the PUFs greatly increased compared to that of APP-PUFs. Addition of 1.5~1.9 wt% ammonium polyphosphate to the PUFs greatly enhanced the thermal stability of the PUFs, so 50 wt% residual temperature of APP-PUFs increased to $380{\sim}488^{\circ}C$, which were $30{\sim}70^{\circ}C$ higher than those of the PUFs. Thermal stability of the PUFs and APP-PUFs increased with $H_2O$ content and then decreased once $H_2O$ content exceeded 5 php.
