This research developed a smart girdle for adult women in their 20's that has an inserted carbon weaving heater to help with relief from coldness and abdominal disease through the thermal insulation effect. A pocket of powernet fabric was attached to the inside of the girdle for the easy insertion and separation of the heating device, while the heating device was fixed to a mesh material by cotton yarn and was wrapped with elastic lining material to prevent the mechanical devices from being exposed. A set of 3 hooks was attached to the center of the back of the heating device in consideration of convenience and mobility. Whereas the switch was inserted into around the right waistband, and the battery into the inner pocket around the waist, to integrate the heating device with the girdle. The satisfaction and usability of the fabricated smart girdle was verified by having research participants wear it to evaluate the appearance change caused by the device, the inconvenience of wearing/unwearing, mobility, and the satisfactory functionality of the device. As a result, the grand mean was evaluated to be high, with appearance (4.19), mobility (4.17), and functionality (4.51) being higher than 4.00; which indicates that the heat generation function of the smart girdle is effective. It may be said that such collection and analysis of data that reflect users' opinions have value and significance in that they can be grafted onto future research on new technology as well as they contribute to taking a step forward in the rapidly increasing research of smart clothing, with the new-type clothing equipped with new function.

Removal of subgingival calculus is essential for the success in periodontal treatment. Subgingival instrumentation is used for the removal of all bacterial plaque and calculus. In this study, two types of anterior curet were used on ant. teeth to conduct subgingival scaling and root planing. The remaining amount of calculus was evaluated according to type of instrument, depth of pocket, and tooth surface. 24 teeth extracted from patients being treated at Dan Kook University dept. Perio. were used. 4 surfaces per tooth a total of 96 areas were evaluated. 12 teeth treated with Gracey No. 1-2 was used as the control group and 12 teeth treated with Mini-five curet No. 1-2 was the experimental group. The 4 surfaces of the teeth {buccal, mesial, lingual or palatal, distal) were observed under a stereomicroscope and the images were captured 3 times per surfaced with a CCD. The image were observed on the monitor using a $10{\times]10$ grid produced with the Microsoft power point. The amount of calculus remaining was evaluated 3 times per surface. The results were as follows. 1. There was no significant difference in remaining calculus according to the pre-treatment pocket depth, and tooth position{Mx. or Mn). 2. The Mini-five curet showed better results than the Gracey curet but there was no statistically significant difference. 3. In both Gracey curet group and Mini-five curet group the lingual(or palatal) surface showed significant difference compared to the other surfaces(p<0.05). From the results above, it is thought that when treating ant. teeth consideration of the tooth surface is more important than the choice of instrument.

Site-directed mutagenesis was employed to generate five different triple point mutations in the double mutant (C295A/I86A) of Thermoanaerobacter ethanolicus alcohol dehydrogenase (TeSADH) by computer-aided modeling with the aim of widening the small alkyl-binding pocket. TeSADH engineering enables the enzyme to accept sterically hindered substrates that could not be accepted by the wild-type enzyme. The underline in the mutations highlights the additional point mutation on the double mutant TeSADH introduced in this work. The catalytic efficiency ($k_{cat}/K_M$) of the ${\underline{M151A}}$/C295A/I86A triple TeSADH mutant for acetophenone increased about 4.8-fold higher than that of the double mutant. A 2.4-fold increase in conversion of 3'-methylacetophenone to (R)-1-(3-methylphenyl)-ethanol with a yield of 87% was obtained by using ${\underline{V115A}}$/C295A/I86A mutant in asymmetric reduction. The ${\underline{A85G}}$/C295A/I86A mutant also produced (R)-1-(3-methylphenyl)-ethanol (1.7-fold) from 3'-methylacetophenone and (R)-1-(3-methoxyphenyl)-ethanol (1.2-fold) from 3'-methoxyacetophenone, with improved yield. In terms of thermal stability, the ${\underline{M151A}}$/C295A/I86A and ${\underline{V115A}}$/C295A/I86A mutants significantly increased ${\Delta}T_{1/2}$ by $+6.8^{\circ}C$ and $+2.4^{\circ}C$, respectively, with thermal deactivation constant ($k_d$) close to the wild-type enzyme. The ${\underline{M151A}}$/C295A/I86A mutant reacts optimally at $70^{\circ}C$ with almost 4 times more residual activity than the wild type. Considering broad substrate tolerance and thermal stability together, it would be promising to produce (R)-1-(3-methylphenyl)-ethanol from 3'-methylacetophenone by ${\underline{V115A}}$/C295A/I86A, and (R)-1-phenylethanol from acetophenone by ${\underline{M151A}}$/C295A/I86A mutant, in large-scale bioreduction processes.

In this study, 110 adults aged 40 to 69 years were surveyed from April 28, 2016, to May 28, 2016 to analyze their periodontal status according to daily stress, coping methods, and oral health behavior. The collected data were analyzed using the t-test, one-way analysis of variance, and hierarchical multiple regression. Daily stress levels of all subjects were most frequent potential risk 64.5% of the subjects, the high risk 19.1% and 16.4% of the health group. Regarding stress coping methods, active methods recorded 2.46, passive methods recorded 2.32. Regarding oral health behaviors, subjects brushed an average of 2.45 times daily, for an average of 2 minutes. Futhermore, 69.1% of subjects brushed before bedtime and 89.1% practiced scaling. Regarding periodontal status, the O'Leary index was 73.45, gingivitis index was 1.30, an average of 2.83 quadrants possessed a periodontal pocket. The hierarchical multiple regression analysis identified, type of employment (${\beta}=-0.348$), scaling (${\beta}=-0.253$), and age (${\beta}=0.244$) as factors that influence the number of quadrants possessing a periodontal pocket. These results confirmed that the oral health behavior of scaling, but not stress levels of coping methods, strongly influenced periodontal status.

The ratio of the elderly population is rapidly growing due to socio-economic development and better medical services. As the average life-span of the Korean elderly becomes longer, the proportion of the elderly is increasing. Therefore, the elderly need to sustain a high quality of life. However, all these factors, such as sensory loss, decreased endurance, mobility limitation, and a loss of independence, act to diminish the quality of life among the elderly. It is necessary for elders to adapt themselves to aging, to maintain their physical functions and especially, it is important to keep their independence in activity of daily living and self care. Therefore, this study was designed to identify the degree of activity in daily living and exercise of a self-care agency and to investigate the relationship between activity of daily living and self-care agency. Also, this research aimed to contribute to nursing interventions that maintain and promote quality of life of the elderly and to enable themselves to live independently. The subject of this study were 160 elders, over age 65, who were sampled in C city. Data were collected by observation and questionnaires from May,1999 to December, 1999. The measurement tools were Barthel Index(1979), Lawton & Brody(1969) for activity of daily living and Kearney & Fleischer(1979) for self-care agency. Data were analyzed by SAS PC+ package and included descriptive analysis, t-test, ANOVA, Pearson correlation coefficient, and Cronbach's alpha. The conclusions of this study are summarized as follows; 1. The mean of ADL and IADL was 96.09 and 16.38, respectively. The score described activity of daily living among the elders in C province as moderate. Particularly, in the items of IADL, the item of medication was the highest score. 2. The mean for exercise of self-care agency was 76.48, a moderate degree. 3. The degree of ADL and IADL according to demographic characteristics was significantly different statistically in pocket money, the presence of disease, perceived health status and in occupation, pocket money, family type, the presence of disease, and perceived health status, respectively. 4. The dagree of selt-care agency according to demographic characteristics was significantly different statistically in gender, education level, economic status, and pocket money. 5. There was a significant positive correlation between activity in daily living and self-care agency. Based on these results, further research is suggested to discover the variables influencing the activity of daily living and self-care agency to develop nursing strategies for improving self-care and activity of daily living among the elderly.

The purpose of this study is to develop a high-strength, high-toughness, thin-walled aluminum shock absorber housing product by applying a high vacuum die casting method to improve internal gas defect and formability. The analysis program dedicated for the casting was used because it was too costly and time-consuming to adopt the gating system design. The final casting plan was designed based on the flow pattern of the material filled into the mold and the result of air pressure and air pocket after the material was completely filled in the mold. Gaty shape was designed as a split type. The runner was designed to have the same shape as the initial inlet curve of the cavity, and the flow of the molten metal was prevented from turbulent flow. The most favorable results were obtained when the injection speed was $V_2=4.0m/s$. Defects on pores were reduced by applying high vacuum level inside the mold.
