In this research, we attempted to explore the mediating effect of SNS usage motivation in relation between covert narcissism and SNS addiction proneness. For this purpose, data was collected from among middle and high school students in cities Chungcheongnam-do, Daejeon, and analysed through multiple-path mediated effect, applying bootstrapping technique The research results are summarized as follows First, the relationship between covert narcissism and SNS addiction proneness has a significant statistical effect. Second, there is significant positive effect between covert narcissism and SNS usage motivation, excluding information seeking motivation. Third, only self-status, entertainment motivation have a statistically significant effect between SNS usage motive and SNS addiction proneness. The results showed that the sub-scales of SNS usage motivation (self-status, entertainment motivation) mediated the relationship between covert narcissism and SNS addiction proneness. Fourth, covert narcissism, self-status motivation, and SNS addiction proneness were significantly different according to gender. Mediated moderation analysis shows that men are more likely to have SNS addiction proneness due to the influence of self-status motivation. Based on these results, implications and limitations of the study and suggestions for future research were discussed. 본 연구는 SNS 중독경향성에 영향을 미치는 변인으로 내현적자기애를 설정하고, 내현적자기애와 SNS 중독경향성 간의 관계에서 SNS 이용동기(대인관계 추구동기, 지위추구동기, 정보추구동기, 오락추구동기)의 매개효과를 탐색하고자 하였다. 이를 위해 대전․충남권의 중․고등학생 295명을 대상으로 자료를 수집하였고, SPSS 21.0과 PROCESS Macro 통계프로그램을 사용하여 자료를 분석하였다. 연구 결과는 다음과 같다. 첫째, 내현적자기애와 SNS 중독경향성 간에 유의한 정적 상관이 있었다. 둘째, 내현적자기애와 SNS 이용동기 간의 관계에서 대인관계추구동기, 지위추구동기, 오락추구동기만이 유의미한 직접효과가 나타났다. 셋째, SNS 이용동기와 SNS 중독경향성 간의 관계에서 지위추구동기, 오락추구동기만이 유의미한 직접효과가 나타났다. 또한 SNS 이용동기 중 지위추구동기와 오락추구동기가 내현적자기애와 SNS 중독경향성 간의 관계를 매개함을 확인하였다. 넷째, 내현적자기애, 지위추구동기, SNS 중독경향성의 변인이 성별에 따라 유의한 차이를 보였고, 매개된 조절분석을 실시한 결과 내현적자기애가 높은 남성은 내현적자기애가 높은 여성보다 지위추구동기를 통해 SNS 중독경향성에 빠질 경향성이 유의하게 높았다. 이는 내현적자기애 성향의 개인이 지위추구동기, 오락추구동기를 갖고 SNS를 사용할 때 SNS중독이 될 위험이 높으며, 지위추구동기가 높은 남성은 SNS에 중독될 위험이 더 높다는 것을 의미한다. 연구 결과를 바탕으로 연구의 의의 및 제한점과 후속연구를 위한 제언에 대해 논의하였다.

Twenty one cows in Goyang and Paju cities were referred due to displacement of the abomasum and foreign body in the rumen. Omentopexy and rumenotomy through a right flank celiotomy were performed for treatment of abomasal displacement and the foreign body removal in the rumen. The right paralumbar fossa is clipped and prepared surgically. Local anesthesia is instituted by performing inverted L block. The abdomen was entered through 25 to 30 cm vertical incision in the right paralumbar fossa starting 4 to 5 cm ventral to the transverse processes of the lumbar vertebrae. A 14-gauge needle with rubber tubing attached is inserted to relieve the gaseous pressure and to facilitate further exploration and manipulation. The rumen was gently pulled out of the abdominal cavity and incision was made at the omentum. Rumenotomy was done and retrieved the foreign body. After the rumen was rinsed with sterile saline,the rumen wall was closed by a Lembert suture technique. The omentum was closed by a simple continuous suture. Right flank omentopexy was performed for the surgical correction of abomasal displacement. Recovery results among 21 cows included 9 excellent, 5 good, 2 fair and 5 bad. It was considered that operation of abomasal displacement and foreign body removal in the rumen through right flank celiotomy was a good surgical technique to reduce expenses,surgical pain, and surgery time.

A numerical simulation of unsteady axisymmetric turbulent flow was performed for a reciprocating engine including port/valve assembly. The governing equations based on a nonorthogonal coordinate formulation with Cartesian velocity components were used and discretised by the finite volume method with non-staggered variable arrangements. The modified $\kappa-\xi$. turbulence model which included the effect of compressibility was used. The results of twodimensional transient calculation for the axisymmetric configuration were compared with the experimental data. Although slightly low rms velocity was predicted compared to the experimental data, predicted velocity distributions at the valve exit and in-cylinder region showed good agreements with the experimental data. The flow at the valve exit was separated at the same valve lift position with the experimental data. Two vortices incylinder region were generated during the initial intake process. The clockwise main vortex became strong and moved upward to the top wall. The counter-clockwise second vortex became weak and stick to the upper left corner of the cylinder. After middle intake process, new vortex adjacent to upper cylinder wall appeared by the piston motion and therefore, the in-cylinder flow was formed into three vortices. The cylinder pressure just before bottom dead center of piston was higher than inlet pressure and then the reverse flow occured at the valve exit. The in-cylinder flow characteristics were strongly dependent on piston motion, but insensitive to valve motion.

The preventive effects of calcium gluconate injection and administration of anion feed on occurrence rates of the abomasal displacement and retained placenta were examined from 86 pregnant cows reared in Paju and Goyang cities in Gyunggi Province. The cows were divided into 3 groups : control (30 heads), experimental group I (28 heads) and experimental group II (28 heads), respectively. The control cows were not treated at all. The cows in experimental group I were intravenously injected with calcium gluconate(CMPK, Am. Tech. Canada, 10g/head). The cows in experimental group II were given with the anion feed (Goyang TMR, Korea, 9kg/head/day). The occurrence rates of the abomasal displacement in experimental groups were lower than that of control group and experimental group revealed the lowest prevalence rate, however, significance was not detected. The occurrence rate of retained placenta in experimental groups revealed lower prevalence than that of control group and experiment group II showed the lowest prevalence rate(p<0.01). Considering the above findings collectively, it was thought that administration of anion feeds was affective for prevention of the bovine retained placenta during drying milk period.
