The main purpose of this study is to investigate the effects of motivation of the employment in Korea with gender, nationality, motivation of studying in Korea, major satisfaction and Korean proficiency level of foreign students who are studying in Korea. The second purpose is to analyze the current factors, to leverage educational management and to make and support some policy of Minister of Education for international students in order to promote utilization of employment of the students in Korea during 4 years of studying. This paper is used by IBM SPSS Statistics 24 Version for data analysis. As a result of the analysis, the average of students in Southeast Asia, Central Asia and South and North America Africa was higher than Japan and China in terms of motivation of employment in Korea. First, the external motivation to study in Korea has affected TOPIK with positive influence. Second, in the relationship between motivation to study in Korea and the majors satisfaction, the higher the internal motivation of study, the higher the majors' satisfaction level. Third, in the relationship between motivation to study in Korea and motivation of the employment in Korea, internal motivation to study has a positive effect on motivation of the employment. As internal motivation increases, grade of the motivation of the employment increases. Fourth, the relationship between major satisfaction and employment showed positive (+) effect. In other words, the higher the major satisfaction, the higher the motivation of the employment. Fifth, TOPIK has a negative effect on motivation of the employment. It means that external motivation was the main factor that positively influenced TOPIK and internal motivation was also main factors that positively influenced both major satisfaction and motivation of the employment in Korea. Sixth, when the internal motivation has an effect on motivation of Korea employment, the higher the major satisfaction as the parameter, the higher the motivation of Korea employment. Therefore, it will be helpful to understand the meaning of studying motivation and major satisfaction of international students, and to be used as basic data on education policies of universities and governments supporting the career and employment for international students.

Objective : The purpose of this study is to understand whether group Sensory Integration(SI) therapy has the effect on improvement of motor skill and social function for children with developmental disorder. Method : The subjects were recruited among children received sensory integration therapy at a Children's Development Institute in Dae-Jeon, experimental group is total 5 participating in group sensory integration therapy and control group is also 5 participating in individual sensory integration therapy. The program was constructed for 90 minutes and all children either in the experimental or in the control group went through intervention for 20 weeks. Bruininks-Oseretsky test of Motor Proficiency II, Korean-Scales of Independent Behavior-Revised and Social Maturity Scale were used in order to evaluate the degree of improvement in motor skill and social function. Results : Most children in the experimental group showed improvement in overall aspects of motor skill and the social function comparing pre-intervention with post-intervention, but they did not show any statistically significant differences. However, comparing experimental group with control group, children in the experimental group showed improvement in motor skill and social function. Furthermore, there is statistically significant improvement especially in manual coordination, manual dexterity, and social age and social quotient in Behavior-Revised and Social Maturity Scale. Conclusions : It is found that a group Sensory Integration therapy program has effect on motor skill and social function for children with developmental disorder in this study. In the future study, group SI therapy should be applied for children with diverse diagnosis in order to generalize the effectiveness of therapy.

This study examined grapheme-to-phoneme regularity effect among late Korean-English bilinguals by using whole word level task (lexical processing) and two meta-phonological tasks(sub-lexical processing): [1] English word naming task(whole word level), [2] rhyme judgement task(rhyme level), and [3] phoneme deletion task(phoneme level). Forty-three late Korean-English bilinguals participated in all three tasks. In these tasks, participants showed better performance in regular word conditions compared to irregular word conditions, demonstrating a clear English regularity effect. Post-hoc correlational analysis revealed strong correlation between word naming task and rhyme judgement task, which is different from the results reported with English monolinguals. The contradicting results might be due to the relevantly low English proficiency level among late Korean-English bilingual speakers. In conclusion, this study suggests that late Korean-English bilinguals make use of L2 grapheme-to-phoneme conversion (GPC) rule when reading L2 English words.

Extractions fro fertilizer and soil samples were performed to yield the operationally defined fractions 'soluble' chromate (extractable with $NH_4NO_3$), 'exchangeable' chromate (extractable with phosphate buffer pH 7.2), and these results were compared with the data obtained by extractions with ammonium sulfate, borate buffer pH 7.2, saturated borax pH 9.6, and polyphosphate (Graham's salt). In order to maintain the pH of extractant solution about constant, the concentration of extractant buffer had to be raised to at least 0.5 M. The results strongly depended on the kind of extractant, and the solid: liquid ratio. For most of the samples investigated, the extraction efficiency increased in the order borate-sulfate-nitrate-phosphate. Whereas the recovery of $K_2CrO_4\;and\;CaCrO_4$ added to the samples of basic slags prior to the extraction was about complete, the recovery of added $PbCrO_4$ was highly variable. In soil extracts, the color reaction was interfered from co-extracted humics, which react with the chromate in weak acid solution during the time period necessary for color reaction (1 hour). However, this problem can be overcome by standard addition and subtraction of the color of the extractant solution. In soil extract of about pH < 7, organic material reduced chromate during the extraction period also, and standard addition of soluble chromate is recommended to prove recovery and the stability of chromate in the samples. In admixtures of soils and basic slags, results for hexavalent chromium were lower than from the mere basic slags. This effect was more pronounced in phosphate than in nitrate extracts. As a proficiency test, samples low in organic carbon from contaminated sites in Hungary were tested. The results from $NH_4NO_3$ extracts satisfactorily matched the results of the Hungarian labs obtained from $CalCl_2$ extractants.

The purpose of this study is to evaluate the intravenous (IV) sedation technique with midazolam and ketamine for uncooperative dental child patients. Three child patients between the ages of 4.4 years and 5.6 years who required sedation for dental treatment were given midazolam and ketamine. Initial dosage was combined of $0.03{\sim}0.06mg/kg$ midazolam and 1.0mg/kg ketamine. Additional dosages of ketamine (0.33mg/kg) were given as needed to maintain deep sedation. Pulse rate, respiratory rate, blood pressure, oxygen saturation, adverse reactions, postoperative recovery and behavior were monitored with saturation pulse oximetry, ECG, NIBP and Cardiocap. In conclusion, the combination of midazolam and ketamine is efficacious in deep sedation for painful dental treatment. However, a significant drop in oxygen saturation was observed as a common adverse side effect. Therefore advanced airway management proficiency is required in order to achieve a successful IV sedation.
