Purpose: This study was to investigate the differences abdominal muscles activities of according to hip adductor contraction levels 20% (mild), 50% (moderate), and 70% (strong) of MVIC on during bilateral lower extremity raising exercise on supine. Methods: The subjects of the study were a total of 39 persons including 23 healthy males and 16 females, who performed bilateral lower extremity raising exercise in 20%, 50%, 70% MVIC hip contraction. Muscle activities were measured by using S-EMG in RA (rectus abdominis), IO (internal oblique), and EO (external oblique). Results: Muscle activity of the internal oblique abdominal muscle and external oblique abdominal muscle, their activities were also greatest with the adductor contraction size at 70% and there was statistically significant difference when compared with the adductor contraction size at 20% and 50% (p<0.05). As for the rectus abdominis muscle according to the size of contraction of the adductor was greatest at 70%, without statistically significant difference (p>0.05). Conclusion: bilateral lower extremity raising with strong hip joint adductor contraction was effective exercise to strengthen abdominal muscles. If subjects could not perform strong hip adductor contraction, moderate contraction is effective abdominal muscle contraction exercise. The contraction size of the adductor is small, weak contraction may trigger middle level contraction and therefore appropriate application of the exercise program of bilateral leg raising may result in great effect as a lumbar stabilization exercise.

The purpose of this study is to verify the effect of raising plants at home on elementary school students' emotional intelligence. The experimental group in the post-test showed significant differences in all the domains of emotional perception, emotional expression, emotional empathy, emotional control, emotional application, compared to the control group, which indicated that the activity of raising plants at home has positive effects on the emotional intelligence of high graders in elementary school. Even in the change of students' emotional intelligence according to their gender, male students in the experimental group had higher average values more than the control group, showing significant differences in all the domains of emotional perception, emotional expression, emotional empathy, emotional control, emotional application. Female students in the experimental group had the same tendency. Accordingly, as a result of this study, it was found that the activity of raising plants at home has positive effects on the improvement of elementary school high graders' emotional intelligence.

The purpose of this study was to identify the caregiving reward of grandmothers raising their infant grandchildren and to examine factors influencing rewards in double-earner households. Data were collected from 323 grandmothers raising infant grandchildren who are under 6 years of age in double-earner households in Seoul, Gyeonggi-do and six metropolitan cities. According to the hierarchy multiple regression analysis, grandmothers' caregiving reward was found to be significantly high. It was also appeared that main factors of the rewards of grandmother were grandparents meaning, relationship with adult children and economic level. This study implies that improving grandparents meaning, relationship with adult children, and economic support may be a strategy to enhance the reward of grandmothers raising infant grandchildren. These findings suggest that there is a need to provide intervention and welfare policy for elderly caregiver.

This research aims at building the conceptual model and proposing concrete ways for raising the ICT productivity of the under-served groups. This research consists of four areas: 1) review and discussion of studies on digital divide issues, 2) theoretical reasoning of the relationship between informatization and productivity, 3) analysis of the present status of information gap between the under-served groups and the general public in Korea, finally 4) proposing the directions of policy making and various concrete ways for reducing information gap and raising the ICT productivity of the under-served groups through facilitating digital inclusion. The model of enhancing the ICT productivity of the under-served groups was theoretically reasoned to include three dimensions which are named as Economy, Efficiency and Effectiveness. The results of this research can be utilized for making policies of not only enlarging the digital opportunity of people in the under-served groups but also raising their income level and quality of life.

Sediment yields from the reservoir watershed areas and raising of the spillway crest for the agricultural reservoir capacity enlargement were investigated and analysed through the 21 pilot reservoirs, have irrigated areas 200has. and over in the Kyoungpook province. In these studies, (1), the correlation analysis between various watershed characteristics and annual specific sediment yields were derived and (2), the excess effective reservoir capacity of the over 0.5m above the spillway crest could be estimated. In brief, catchment area should strongly be correlated with the annual specific sediment yields (R=0.90), the other side, average slope of the main stream is less than catchment area. The excess effective capacity of reservoir enlargement by the raising of spillway crest at 0.5m-height was resulted 12.1% of increasing capacity compare with the original reservoir capacity.

The action of acetylcholine on the sodium plus potassium activated ATPase activity in the rabbit red cell membrane has been investigated and the experiments were also designed to determine the mechanism of action of acetylcholine on the ATPase activity. The following results were observed. 1. The activity of the NaK ATPase from red cell membrane is inhibited by acetylcholine. 2. The ratio of inhibition of NaK ATPase by acetylcholine is decreased by raising the potassium concentration, and is increased by raising the sodium concentration. 3. The ATPase activity is increased by small amounts of calcium but inhibited by larger amounts. The ratio of inhibition of the enzyme by acetylcholine is increased by raising the calcium concentration. 4. The inhibitory action of acetylcholine on the NaK ATPase activity was not related to the sulfhydryl group of cysteine, the hydroxyl group of threonine, or the carboxyl group of aspartic acid. 5. The inhibitory action of acetylcholine on the ATPase activity is due to amino group of the enzyme of NaK ATPase.

Though pheasants (Korean ring-necked pheasant) have been raised for several decades, their behavior and wild nature are far from domestication. The pheasant is a seasonal breeding species and lays a limited number of eggs in a breeding season. The growth rate and feed efficiency of pheasants are very low as compaired with those of chicken for meat purpose. In addition, the breeder's access to one's herd for care is not easy. From these reasons, pheasants seem to be unsuitable for meat production in a large flock at present. However, pheasant raising is expected to increase slowly in accordance with rising demand for special poultry meat. Therefore, it is necessary to improve techniques about raising, feeding and rnanagement, so that the consumer price of pheasant meat can be lowered down reasonably.

This paper aims at showing firstly, that the parameterized Universal Grammar is also accessible in second language acquisition based on the data found in the English Agreement acquisition by Korean speakers and secondly, that the theoretical claim that the acquisition of Agreement is related to the Subject Drop phenomenon can be supported by the second language acquisition data. The functional category AGRP which is crucial here can be parameterized according to its features with Korean of - Agr and English of + Agr. Two groups of 40 each were tested and the result shows that the parameter resetting is possible in terms of the Agreement feature. In addition to Agreement test, three more tests for the distribution of Subject Drop, Subject Raising and NPI (Negative Polarity Items) were conducted in order to find the correlation among those grammatical phenomena. The result is that the acquisition of Agreement and the Subject Drop possibility are correlated but that they are not related to the obligatory Subject Raising process. Finally, NPI distribution test which is supposedly related to the Subject Raising turned out to carry little information since the average grades from both groups were very low.

Purpose: The purpose of this study is to examine factors affecting quality of life among grandparents raising their grandchildren. Methods: This study carried out a secondary analysis of data from the 2014 Korean Longitudinal Study of Aging (KLoSA) and Statistics Korea. Data collected from 224 grandparents who reported raising their grandchildren were analyzed using descriptive statistics, independent t-test, ANOVA, pearson correlation coefficient, and multilevel regression analysis. Results: The mean score of the participants' quality of life was 62.63. Significant predictors of quality of life of the grandparents included subjective health status, last year's total house income, number of last year's travels, frequency of last year's movie seeing, and number of children's parks per 100,000 population. Conclusion: These results suggest that public health nurses in improving quality of life of grandparents focus on children's parks and formal social supports as community factors as well as regular exercise as an individual factor in order to be more effective.
