  • This study is focused on the effects of elder's blood type on determining awareness and emotional character of the elderly, by comparing each individual's brain wave. Observed records are from thoes elder's who volunteered for KRIJUS( Korea Research Institute of Jungshin Science)'s brain wave measurement from September 2008 to June 2009. The whole 762 elder group consists of 311 female and 451 male. Blood types are A>B>O>AB dominately ordered. The result shown no relations between the blood types and their emotional character among elderly female, while elderly men shown meaningful difference; type B and O had higher rate on negative aspects. When it comes to awareness categories, both emotional(p=.001) and active(right)(p=.040) index shown meaningful differences. Type A had highest rate on emotional index and AB had it on active index. This study revealed meaningful relation between blood types and emotional character among several categories, while suggesting follow-up researches figuring out more detailed explanations for its effect and genetic role.

  • With regard to the manufacture of dental prosthesis, all the dental mechanism is of vital significance at the aspect of activating its function by fixing the prosthesis to Patient's oral cavity. However, if there we will take our immediate action without the discretion about its process none the less for the importance of dental mechanism, then we might have a serious problem. Accordingly, there need to pay attention to the dilatability makes up for the shrinkage state occurring by the feature of metal materials and manufacturing process which appeared in the process of dental mechanism, which eventually is expected to playa very important role in casting a dental prosthesis appropriate to one's oral tissue. This study was designed to take into account of the effects on margin consistency of prosthesis according to the continued time of casting-ring in the course of the casting of dental alloy. For this, the researcher made an experiment on the casting of dental alloy, its dilatability, and the change of phase. The results of this study were as follows: First, the researcher could see that the sample which was cast under the condition of $650^{\circ}C/20$ Minutes(the continued time) was far superior to others at the aspect of margin consistency. Second, according to the measurement of expansion coefficient by Dilatometer, the researcher perceived the fact that the expansion-coefficient showed a maximum of $37.1{\mu}m$ considering the sample's length which was cast with ordinary temperature under the condition of $650^{\circ}C/20$ Minutes. Third, from the result of X-ray diffraction under the condition of $650^{\circ}C/20$ Minutes(the continued time), the researcher could find that there's no difference between the change of phase and its intensity. As mentioned above, the researcher could ascertain the fact that its contraction don't give rise to the change of phase.

  • This study examined the mediating effects of couple communication on self-differentiation and marital satisfaction among married women. The ANOVA, correlation and the multiple regression analysis were used to figure out the relationships and the mediating effects of those variables. The results revealed that self-differentiation was significantly related to marital satisfaction. Also, couple communication was revealed to be a partial and full mediator between self-differentiation and marital satisfaction. The results were as follows. First, there were differences in couple communication and marital satisfaction. Marital satisfaction showed differences according to socio-economic variables such as educational level, occupation, family income, and the years of married life. Educational level and family income made differences in couple's communication. However, socio-economic variables did not make any difference with regard to self-differentiation. Second, there was a significant correlation among all sub-factors for self-differentiation, whole self-differentiation, married couples' communication, and marital satisfaction. Third, the result shows that the mediating effect of couple communication between self-differentiation and marital satisfaction. Couple communication completely mediated the relationship between cognitive vs. emotional function, family projection, emotional cutoff, and marital satisfaction. It also partially mediated the relationship between family regression and marital satisfaction. In addition, there was a tendency to partially mediate the relationship between general self-differentiation and marital satisfaction. The results suggested that self-differentiation and couples communication should be considered together when explaining marital satisfaction among married women. Also, the results implied the importance of the increased self-differentiation and the better couple communication in women's marital satisfaction. Finally, this research suggested the necessity of counseling services to enhance the self-differentiation as well as couple communication programs for the marital satisfaction of women.

  • For the office work environmental design, the importance of the design management is increased to improve operation efficiency as well as the aesthetic environmental implementation of the function today. Lighting is a required element ineffective operation environment. It has become more important for the aesthetic, economic, and practical reasons, to consider the luminous environment and the lighting of visual tasks separately. When the brightness is insufficient, productivity deteriorates, and the layout of the lighting located by mistake causes the fatigue of eyes. Productivity rises to office in a large number of studies so as satisfaction is low in general in the dark office, and to be bright. Therefore the purpose of this research is to suggest the right direction of lighting design of office building area. 11newly renovated office buildings are selected for this luminous environment research. We could conclusions as following through this research. First, it was planned brighter than the recommended lighting level in the most space. It shows that the accurate lighting design criteria is needed in order to achieve proper lighting environment. Second, the application of the LED lighting fixtures is continuously increased in the recent office lighting environment. It is explained that it is applied for reasons of the electrical energy reduction and the maintenance efficiency with the long life time. Third, the consideration of the lighting plan for the difference of working types is not enough. with various communication configuration through an independent plan, and the effective lighting plan that appropriateness preparation design and energy saving area vailable must be applied. Fourth, the lighting environment of the lobby needs a specialized lighting plan as are presentative space of the building.

  • The study performed analysis focusing on specialized convention and exhibition facilities among convention and exhibition facilities in Korea. The procedures and results were as follows: First, by theoretical consideration, meaning and contents of convention and exhibition programs done in convention and exhibition facilities were considered and after that, general characteristics of the programs which were the main of space utilization was derived. Second, considering scale and location, 6 facilities were re-selected for in-depth research from 12 facilities investigated preliminarily. Selected facilities were categorized by scale and through the analysis of programs done in this facilities for the last 1 year, overview and characteristics of utilization for exhibition space, conference space, and multi-purpose space, etc were analyzed. Third, through the case study on the programs, individual characteristics of space utilization by convention and exhibition program were analyzed. From the result of the study, considering the whole, the space utilization of programs was done as conference space rather than exhibition space and the ratio of use as conference space to use as exhibition space was 1.8 in the large facilities, 6.7 and 7.6 in the middle facilities and the small facilities, respectively. In the middle and small facilities, the ratio of use of one room as conference space was very high. In the large facilities, there was no big difference with the ratio 50:50 of the programs involving exhibition to other programs, but in the middle and small facilities, the ratio of the former to the latter was observed over 2.4 and 3.6. This fact indicated that the function of use as promotion and communication space for companies and industrial entities which were the essential purposes became low.

  • The effects of Taheebo on the diabetic-piegnant rats and their fetus was investigated. It has been reported that diabetic condition of the pregnant rats can affect the process of liver formation and damage the respiratory function in the fetus. Therefore we investigated the effects of Taheebo on the prevention of liver damage and respiratory failure in the fetus and those results were compared with that of dexamethasone (DXM). In pregnant rats, streptozotocin(STZ, 45 mg/kg, 0.01 M citrate buffer) was injected into the pregnant rats on the third day of pregnancy. Methanol extracts of Taheebo(500 mg/kg p.o.) was administered once daily during pregnancy. DXM (10 $\mu\textrm{g}$/g i.p.) was injected into the pregnant rats in 16th and 18th days of pregnancy. Body weights were measured and fetal number and abortion rate in pregnancy rats were determined. Lecithin/sphingomyelin ratio in amniotic fluid and malondialdehyde, glycogen, triglyceride, protein and cholesterol levels in the liver homogenate were determined. Also blood glucose level was analyzed. Body weights of maternal rats were increased in the all groups except the DXM group. Fetal number of the Taheebo treated group was similar to the control group, and a significant increase in the body weights of fetus was observed in the STZ treated group and the Taheebo treated group compared with the control group. Blood glucose of fetus produced hypoglycemia in the control group and hyperglycemia in the diabetic-pregnant rats. The protein and cholesterol levels in fetus liver were significantly increased in the DXM treated group compared with the control group. Triglyceride content was significantly increased in all groups compared with the control group. Liver malondialdehyde level of fetus in the STZ treated group was similar to the control group. Glycogen level was significantly increased in the all groups compared with the control group. Methanol extract of Taheebo showed hypoglycemic effect on the pregnant rats. However, we could not observe any hypoglycemic effect on the fetus. There's no difference between the control and Taheebo treated group in terms of the levels of triglyceride, cholesterol, protein and glycogen in the fetus liver. Further study to identify the effect of Taheebo on the fetus is under investigation.

  • The purpose of this study was to investigate the relationship between parents' behavior during picture-book reading and home literacy environment and their effects on toddlers' vocabulary. The subjects of the study were 46 toddlers and their parents. The MCDI-K(Im, 2002), Lee and Kim(2004)'s categories of Verbal Behaviors, the categories of Nonverbal Behavioral Analysis(Kim, 2005), and the Home Literacy Environment Index(Han, 2006) were used. The analysis of the collected data was guided by the research questions and involved the use of descriptive statistics, t-test and an analysis of relevant correlations. The results of this study were as follows; First, the toddlers' receptive vocabulary score was 1.2 times higher than the toddler's expressive vocabulary score. Second, the father's book reading behaviors and mother's book reading behaviors were quite similar, the most frequent types of behavior being the use of 'feedback', 'explanation', 'questioning' and 'pointing'. On the other hand, there was a significant difference between the reading behavior of the mother and father as regards the categories of 'linguistic attention ventilation', 'suggesting', 'directing(instructing)', 'expanding feedback', 'pointing' and 'gesture'. Mothers performed more of these behaviors than the fathers. Third, toddler's vocabulary scores were positively correlated with the mother's 'linguistic attention ventilation'. However, the mother's use of 'restriction' was negatively correlated with the toddler's vocabulary level. Toddler's vocabulary scores were positively correlated with the father's 'description', 'reasoning/predicting', 'questioning about function or action', 'demanding feedback' and 'pointing'. The toddler's vocabulary scores were also positively correlated with the relative abundance of home environment materials and the amount of time spent on parent-child home literacy activity.

  • The lumbrical muscles contribute to the intrinsic plus position, that is simultaneous metacarpophalangeal (MCP) flexion and interphalangeal (IP) extension. The strength of the lumbrical muscles is necessary for normal hand function. However, there is no objective and efficient method of strength measurement for the lumbrical muscles. In addition, previous studies have not investigated the measurement of the cross-sectional area (CSA) of the lumbrical muscles using ultrasonography (US) and the relationship between lumbrical muscle strength in the intrinsic plus position and the CSA. Therefore, the purpose of this study was to identify the measurement method of the CSA of the lumbrical muscles using US and to examine the relationship between maximal isometric strength and the CSA of lumbrical muscles. Nine healthy males participated in this study. Maximal isometric strength of the second, third, and fourth lumbrical muscles was assessed using a tensiometer in the intrinsic plus position which isolated MCP flexion and IP extension. The CSA of the lumbrical muscles was measured with an US. The US probe was applied on the palmar aspect of the metacarpal head with a transverse view of the hand in resting position. There was no significant difference between maximal isometric strength of the lumbrical muscles, but the fourth lumbrical muscle was stronger than the others. The CSA of the lumbrical muscles was significantly different and the fourth lumbrical muscle was significantly larger than the second lumbrical muscle. There was moderate to good correlation between maximal isometric strength and the CSA of the lumbrical muscles. Therefore, we conclude that maximal isometric strength of the lumbrical muscles was positively correlated to the CSA of the lumbrical muscle in each finger, while the measurement of the CSA of the lumbrical muscles, using US protocol in this study, was useful for measuring the CSA of the lumbrical muscles.
