  • This study, to investigate the state of PVW among the clinical dental hygienists and its determinants, has polled 322 clinical dental hygienists working in Daegu, Kyung buk province, and Ulsan. Data were collected by self-administrated questionnaire. A SPSS 12.0 for Windows was used for statistical analysis. The obtained results were as follows: 1. The average of PVW among the respondents was 3.43. 2. The area average of PVW determinants was as follows; job significance, 3.31, process efficiency, 3.42, product usefulness, 3.32, vision realizability, 3.53, social recognition, 3.23 and the total average, 3.36. 3. The married have higher PVW than the unmarried in all areas(p=.012, p=.008, p=.036, p=.007). 4. As for working experience, in the case of perceived self value, those having 1~2 years experience have the highest PVW(p=.000), apart from perceived self value, those having over 6 years experience have the highest PVW in all areas(p=.015, p=.001, p=.002). Relating to the task, those working in the patient consulting and managing part have the highest PVW, relating to the annual salary, those having over 25 million won have the highest PVW(p=.000, p=.000, p=.001, p=.000). 5. The relationship between PVW and PVW determinants, in all respects, is meaningful, so it was found that the higher determinants are, the higher PVW is. 6. The whole explanation variate of PVW determinants was meaningful in PVW, perceived self value, value fulfillment emotion, respectively representing 38.8%, 55.6%, 61.5%(pE.001). PVW of clinical dental hygienists should be considered as a significant criterion of indivisual and organizational effectiveness. To improve effectually PVW of the clinical dental hygienists, there is need to establish culture in a system of hospital that redound to their social recognition.

  • As by-pass dust (BPD) made from cement manufactured process is designated waste, it is required to bury as high cost. The main component of BPD is potassium chloride (KCl), and used for the fertilizer. For using KCl to the fertilizer, the pH value of KCl is required as neutral or weak acid. However, it is not suitable to apply BPD into the fertilizer directly without any other treatment because BPD's pH value is shown 12.0~12.5; a high base. In this study, the carbon dioxide ($CO_2$) was used for removing calcium oxide (CaO) and reducing pH value during manufacturing process of KCl. We fixed inner condition of the carbon test chamber as $25^{\circ}C$-50RH%, and retained 0~7 hours under the 20 vol% of $CO_2$ atmosphere. After experiment, we analyzed the content of CaO and pH value from each samples. The more time exposed to $CO_2$, the content of CaO and pH value are shown. Furthermore, pH value exposed in 6 hours nearly reached 7.

  • The concept and definition of nursing and her role have been changing in accordance with the socio-cultural factors of the initial society. At present, nursing is conceptualized as a health care profession assisting man to restore, maintain and promote health by providing knowledge, wilt strength and resources through various processes of interaction. Man′s behavior, of individual and group activities for health inclusive, is driven by the initial man′s value orientation. The purpose of this study is to investigate the value orientation regarding health of rural health center milieu in order to give data for; 1. the planning for the delivery of community nursing service, 2. the health education plan at all level of nursing care activities, and 3. the planning of curriculum for nursing education. A hundred opinion leaders among the labor population residing in rural areas (P-group), hundred and six professional nurses at rural health centers (N-group) were indirectly interviewed through questionaries. And ninety five of N-group were interviewed likewise of their perceptions of P-group (NP-group) from July 15, to October 15, 1974. The result is as follows: 1. Maintenance of health is revealed to be the most valued component for man′s happiness in all the three groups. (P-group: 7.30 S. D.=1.31), (N-group :7.84 S. D. =49), and (NP-group : 5.93 S. D. =2.28) 2. The average value score of the maintenance of health revealed significant difference by P〈.001 level between each of the three groups. (Between N-group and P-group : T= -4.07 P and NP ; T=-6.93, N and NP: T=-9.35) 3. Basic health maintenance activities necessary for maintenance and promotion of personal health were moderately valued by all the three groups, P-group ; 3.74 (S. D. =.43) , N-group: 3.52 (S. D. =.34), NP-group: 3.07 (S. D. :.55) Among the 8 categories of basic health maintenance activities, "food intake" was highly valued by P-group (mean value score; 4.00 S. D=.51) , "exercise and rest" and "personal cleanliness" was highly valued by both P-group (4.02, 4.08) and N-group (4.08, 4.22). 4. The mean value score of basic health maintenance activities revealed significant difference by P〈.001 level between each of the three groups (between P-group and N-group: T=-4, 07, N-and NP: T=-6.93, P and NP T=-9.35) 5. Among the 30 questionaries, dynamic activities for health maintenance were more valued in comparison to passive activities in an tile three groups. 6. In N-group, correlation between the value of basic health maintenance activities and the personal health status personal revealed moderate significance. Correlation between the value of basic health maintenance activities and the age revealed low significance. 7. In group, correlation between the value of basic health maintenance activities and; perception of personal health status revealed non significance, between the age and sex revealed low sign affiance, and between the educational status revealed moderate significance. Recommendations are as follows ; 1. The efforts towards alteration of value orientation concerning health in general in community nursing practice de focussed be that of family Planning. 2. In order to prepare professional nurses competent in understanding individual and group, social science and behavioral science be strength ended in planning nursing curriculum. 3. Milieu of nursing experience during nursing education be Planned to begin at simple nursing problem and move towards complex, f. e. home care towards health crisis situation in order to achieve dynamic role mastery.

  • In order to investigate the Phenomenon of Acid Precipitation, pH value and Anions of Fluroide, chloride, nitrite, phosphate, bromide, nitrate and sulfate were measured from the acid precipitations sampled around 7 districts over seoul area during period of 9 months from January till September, in 1985. From the distribution of pH value gatnered, acid precipitations were noticed during period from January till Aprill, and from as of April 22nd, situation gradually recovered. The average pH value till April showed comparatively low, ranging 4.0-5.0. The pH value of 4.5-5.6 in average over whole year reaches to similar level of those in Japan. Anion analysis revealed that the main factor of pH value in Seoul district attribute mainly to the sulfate ion and nitrate ion. Moreover, these Phenomena of acid precipitation in Seoul area appeared to concentrate on certain districts, and they are slowly moving toward other directions due to such factors as wind-velocity and directions.

  • Quality characteristics effects of adding four different amounts (0%, 1%, 2%, 3%) of Ulleung-Maesil (Prunus mume fruit) powder cookie doughs were examined. pH, water content & bulk density of dough, spread factor, color value, hardness and consumer acceptability of maesil cookies were measured. The pH and water content of freezedried Ulleung-Maesil powder were 2.01 and 6.26%, respectively, while the L, a, b values were 76.14, -1.66 and 28.65, respectively. Although bulk density of the 3% powder group of cookie dough was the highest, its pH value was the lowest compared to the other groups (p < 0.05). Spread factor of the 3% group showed the lowest value among all groups (p < 0.05). Hardness of the control group (i.e, 0%) was significantly higher than the 1%, 2%, 3% groups (p < 0.05), which showed no significant difference among themselves. The ${\Delta}E$ value of cookies increased significantly with increasing Maesil powder content (p < 0.05). The consumer acceptability scores for control and 1% Maesil cookie groups ranked significantly higher than the 2% and 3% groups in overall acceptability, taste, flavor and texture (p < 0.05). In conclusion, our study suggests that small amounts of Ulleung-maesil can add positive attributes to cookies.

  • Objectives: The purpose of this study was to explore how service quality in specialized hospitals influences customer loyalty under the mediating effects of customer trust and customer value. Methods: A statistical review was done based on the survey results of patients who had used a specialized hospital in Gyeonggi Province, South Korea. A total of 209 questionnaires were collected. After data collection, an empirical analysis was performed using SPSS 21.0 and AMOS 21.0 software. Results: Interaction quality (β = 0.254, p < 0.05) and result quality (β = 0.179, p < 0.05) significantly influenced customer trust, while physical environmental quality (β = 0.121, p > 0.05) did not. Customer trust (β = 0.571, p < 0.01) influenced customer value (β = 0.136, p < 0.05) and customer value influenced customer loyalty. In addition, customer confidence (β = 0.668, p < 0.05) was shown to have directly impacted customer loyalty without the mediating effect of customer value (0.078). Conclusions: The findings showed that interaction quality and resulting quality had important implications for customer loyalty. We therefore suggest compliance with appointment times, training to improve work-related skills for employees, improving customer satisfaction, and enhancing communication skills.
