Factors related to health promotion activities and quality of life in Korean women with arthritis have not been clearly identified. Predictors of health promotion might be identified that will enhance the well - being of this group. Accordingly, the findings of the study will contribute additional information about the relationship between health promotion and quality of life and will add to the research on quality of life of individuals with a leading cause of disability--arthritis. The purpose of the study was to examine the relationship of selected background factors (years of illness, perceived severity of illness, uncertainty in illness), perceived self- efficacy, and health promoting behaviors to the quality of life of Korean women with arthritis. A cross - sectional descriptive design was used in this study to investigate relationships among the variables of interest. The sample was composed of 96 women who had arhtrits and visited large university hospital in Seoul for regular check up or pre-scription of medication. The purpose of a descriptive correlational design was to determine the absence or presence of relationships among variables that were measurable (Polit & Hungler, 1981, p.147). The design of this study was appropriate because it yielded answers to the research questions and hypotheses regarding the relationships among the model variables. the Questionnaire contained demographic information, translated Mishel Uncertainty in illness Scale-Community form (MUIS-C) (Mishel, 1987), translated and modified Disease Course Graphic Scale(DCGS) which was developed by Braden (1990), translated Sherer. et al.’s General Self-Efficacy Scale (1982), The Health -Promoting Lifestyle Profile (HPLP), developed by Walker, Sechrist, and Fender (1987) and traslated to Korean by Ha, and quality of life was measured by Face Scale (Andrew, 1976). Several steps of verification for the translation process were carefully conducted. Data analysis included descriptive correlational statistics and multiple regression techniques. Health promotion was the only contributor to pre-dict quality of life. Results showed that enabling cognitive perceptual factor (self-efficacy) mediates the disruptive force (uncertainty in ill-ness) on achieving a health promoting self- help behavior. The findings of this study also indicated that illness - related variable of severity of illness was mediated by health promotion, which buffered it's impact on quality of life.

Surface modification of silica nanoparticles was investigated using an aerosol self assembly. Stearic acid was used as surface treating agent. A two-fluid jet nozzle was employed to generate an aerosol of the colloidal suspension, which contained 20 nm of silica nanoparticles, surface modifier, and ethyl alcohol. Powder properties such as morphology, specific surface area and pore size distribution were analyzed by SEM, BET and BJH methods, respectively. Surface properties of the silica power were analyzed by FT-IR. The OH bond of the $SiO_2$ surface was converted to a C-H bond. It was revealed that the hydrophilic surface changed to a hydrophobic one due to the aerosol self assembly. Morphology of the surface treated powder was nanostructured with lots of pores having an average diameter of around $2\;{\mu}m$. Depending on the stearic acid concentration (0.25 to 1.0 wt%), the pore size distribution of the particles and the degree of hydrophobicity ranged from 1.5 nm to 180 nm and 29.6% to 50.2%, respectively.

호신용 스프레이의 자극성 액체에 포함된 capsaicin, dihydrocapsaicin 및 nonivamide의 함량을 기체 크로마토그래피로 정량하는 방법에 대해 연구하였다. Capsaicin과 거의 동등한 수준의 매운맛을 내는 nonivamide는 천연물 내에도 극히 소량 존재하므로 합성된 nonvamide를 합성 캡사이신(Synthetic capsaicinoid) 또는 PAVA(Pelargonic Acid Vanillyl Amide)라고 부르며 식품 향미 재료나 폭동진압용 무능화 작용제로 이용되어왔다. 호신용품이 난립하는 요즘 각종 불법 호신용 스프레이의 품질관리가 제대로 이행되지 않는 사례가 종종 발견되고 있다. 따라서 기체크로마토그래피로 합성 캡사이신이 포함된 제품이 천연 유래인 것처럼 도용되거나 허용농도를 준수하는 지를 판별할 수 있는 간단한 분석방법을 개발하고자 하였다. 마지막으로 분석방법이 확립되면 시판되는 호신용 스프레이 내에 존재하는 자극성 액체의 성분과 함량 조사에 응용하여 보았다.

본 연구는 투수시험 실시 후 고로 슬래그 자극제로 $Na_2SO_4$를 첨가한 고로 슬래그 시멘트 페이스트 시편의 자기치유 특성으로서 충진율과 자기치유 생성물을 고찰하였다. 실시한 시편에 대해 충진율과 자기치유 생성물을 분석하였다. 자기치유 정도는 충진율로 평가하였으며 충진율은 객관성을 갖기 위해 BSE-DIP를 이용한 파노라마 분석법으로 실시하였다. 평균 충진율은 Top 부분은 평균 18%, Middle 부분은 평균 7%, Bottom 부분은 평균 5%로 시편의 윗부분에서 아래 부분으로 갈수록 충진율은 감소되는 경향을 나타냈다. 또한 구간별 최대 충진율은 44%이었고 최소 충진율은 3%이었다. 투수시험 후 잔존하는 자기치유생성물은 기본적으로 Ca 원소와 고로 슬래그에서 유래된 Al 원소를 다량 함유하고 있었으며 Si 원소는 균열 표면으로부터 가깝게 위치한 곳에 주로 존재하였다. 자기치유 생성물 중에서 가장 많이 존재하는 광물은 C-A-H로 68% 정도 존재하였다. $CaCO_3$는 13%, C-A-S-H는 8% 순으로 3가지 물질이 자기치유 생성물의 90% 정도를 차지하고 있었다. C-A-H는 주로 균열 표면에서 약간 떨어진 부분에서 존재하였으며 각진 형태 이거나 침상 형태의 형상을 나타냈다. C-A-S-H는 기존의 시편과 자연스럽게 이어지게 표면을 타고 생성되었으며 $CaCO_3$는 시편의 표면이나 균열의 내부 등 위치에 상관없이 전반적으로 보였다.

This paper investigated the influence of binary and ternary blends of mineral admixtures in self-compacted mortar (SCM) on the fresh, mechanical and durability properties. For this purpose, 25 mortar mixtures were prepared having a total binder content of $640kg/cm^3$ and water/binder ratio between 0.41 and 0.50. All the mixtures consisted of Portland cement (PC), fly ash (FA) and silica fume (SF) as binary and ternary blends and air-entrained admixture wasn't used while control mixture contained only PC. The compressive and tensile strength tests were conducted for 28 and 91 days as well as slump-flow and V-funnel time tests whilst freeze-thaw (F-T) resistance and capillary water absorption tests were made for 91-day. Finally, in general, the use of SF with FA as ternary blends improved the tensile strength of mortars at 28- and 91-day while the use of SF15 with FA increased the compressive strength of the mortars compared to binary blends of FA. SCM mixtures with ternary blends had lower the sorptivity values than that of the mortars with binary blends of FA and the control mixture due to the beneficial properties of SF while the use of FA with SF as ternary blends induced the F-T resistance enhancement.

Objective : Halitosis, or bad breath, is a common concern for many people. The aim of this study was to investigate clinical characteristics of halitosis patients and correlation with their various associated elements. Methods: We surveyed 169 halitosis patients by reviewing questionnaires from the Halitosis Clinic in the Hospital of Oriental Medicine, Kyunghee University from January 2004 to March 2006. The questionnaires contained various items including sex, age, history of smoking and alcohol intake, duration of symptoms in a week, time and condition of severe halitosis, suggestive origin of halitosis, taste abnormality, oral hygiene, self-assessed halitosis severity, dry mouth, postnasal drip, tonsillolith, globus pharyngeus, reflux sensation, too much gas and Winkel tongue coating index. Volatile sulfur compounds were measured with a $Halimeter^{\circledR}$. Results : The halitosis patients actively carried out management methods such as non-smoking, moderation in drink, teeth brushing and tongue scraping in order to decrease their oral malodor. Tongue coating significantly affected the $Halimeter^{\circledR}$ reading score, and tongue coating and dry mouth significantly affected self-assessed halitosis severity. Conclusions: Our results suggest that tongue coating and dry mouth should be treated to improve satisfaction in halitosis patients.

This study is to verify the effects of sensory education based on classroom activities for $2^{nd}$ and $3^{rd}$ grade children. The hypothesis is that children who participated in sensory education would demonstrate positive changes in eating behaviors through sensory experiences. The sensory education program consists of 12 lessons. Twenty-six children were being recruited from one school in Changwon, Korea. Two control groups, one of which was the same age as the educated group and the other group of sixth graders, were selected by random sampling from the same school. Children answered a self-administered questionnaire. The parents (n = 20) of the children who participated in the program, took part in evaluating the program through self-administered questionnaires after the program ended. The questionnaire contained variables of general characteristics, education satisfaction, nutrition knowledge, eating attitude and behavior concerning unfamiliar foods. The score of nutrition knowledge was improved in educated children (P < 0.05). Food neophobia score towards unfamiliar foods (P < 0.05) was increased in educated children, but there are no changes in eating behaviors in all groups towards unfamiliar foods. In conclusion, sensory education is useful for having a positive eating attitude among children. Its consistent implementation could lead to healthier and well-balanced eating behaviors for children.

This study aimed to provide directions and implications for a future program by analyzing studies on diabetes programs from 2000 to 2020. Among the studies with control and experimental groups, the selected studies included ones that provided intervention to patients with diabetes and ones that contained descriptive statistics. Sixteen studies were selected to verify the effectiveness and homogeneity of the data coding meta-analysis. The overall effect size in the diabetes program combined estimate was 0.398 (95% CI: 0.268, 0.425, p=0.000). Among the dependent variables, fasting blood glucose (-0.616) and glycated hemoglobin (-0.442) showed median effect sizes, but the effect of fasting blood glucose was not statistically significant. In terms of the study design, non-randomized control trials (NRCTs) (-0.543) was more effective than randomized control trials (RCTs) (0.719). Among, the counseling and self-management program (-3.241) showed a very large effect size. Furthermore, the cognitive-behavioral (-0.828) and self-management (-0.482) programs were also found to have a positive effect on lowering fasting blood glucose. As the importance of diabetes management increases, further studies based on RCT should be actively performed, and differentiated and specialized diabetes intervention plans need to be established.
