Objective : The purpose of this study was to examine differences of psychological symptoms for mothers of infants with autism spectrum disorder(ASD) according to the level of parenting stress. Methods : The subjects were seventy-two mothers of infants with ASD(aged 22 months to 71 months) completed Korean Parenting Stress Index (K-PSI) and Minnesota Multiphasic Personality Inventory(MMPI-2). The data was analyzed using SPSS 23.0 program. Results : First, total and parent domain of parenting stress were positively correlated with several clinical scales of MMPI-2. However, there was no significant association between the child domain of parenting stress and clinical scale MMPI-2. Second, as a result of verified the difference of psychological symptoms according to level of total and parent domain of parenting stress, high-risks group was significantly higher scores in several clinical scales of MMPI-2 relative to those in normal range group. However, regarding the association between the child domain of parenting stress and psychological symptoms, there was no significant difference in psychological symptoms between high-risks group and normal range group. Conclusions : The results of this study have implications for verified the difference of psychological symptoms according to level of parenting stress among mothers of infants with ASD.

Objectives : This study was conducted to investigate differences in psychological characteristics between major depressive disorder (MDD) patients with and without suicide attempt using MMPI-2-RF. Methods : Subjects were 107 MDD patients who had visited the department of psychiatry of hallym university hospital and met the DSM-IV diagnostic criteria of MDD by the korean version of MINI-Plus 5.0.0. The patients were divided into suicidal attempters (n=43) and non-suicidal attempters (n=64) using C-SSRS. The one-way ANOVA was used to compare MMPI-2-RF scale scores between two groups. Additionally, ANCOVA was conducted considering the severity of depressive symptom and comorbidity as covariate. Results : Our results showed that Suicide/Death Ideation (SUI), Inefficacy (NFC) and Interpersonal Passivity (IPP) scales were significantly higher in the MDD patients with suicidal attempt compared to MDD patients without suicidal attempt (p<0.05). However, after controlling for the severity of depressive symptom and comorbidity, SUI scale showed a significant tendency (p<0.10). Conclusions : The result suggests that MMPI-2-RF scales could be a useful tool for identifying patients transitioning to actual suicidal attempts in the moderate or severe major depressive disorder group. Limitations of this study and directions for further research are also discussed.

A brittle fracture is one of the source of structural damage and can bring a fatal accident. The inner shell of LNG storage tank should be designed and applied to construction by ensure that no brittle crack will occur under -162℃ condition. In point of view of fracture mechanics brittle fracture in the structure could be referred as crack initiation and crack arrest. It should be designed no crack initiation. However, in the unlikely event of a brittle fracture occurring, a back-up function of arresting the brittle crack should be included for the design. In this paper investigated the characteristics of 9% Ni steel thick plates of having a capability of arresting brittle cracks under the thickness of 33 mm, 37mm, 40 mm. First, charpy test has performed to evaluate the fundamental brittle impact fracture property of 9% Ni steel under the temperature of 24℃, -162℃ and -196℃. In addition, Duplex ESSO tests were also performed under -196℃ to evaluate the capability of crack arrest for 9% Ni steel. From the experiments results, it was confirmed that all the thickness of 9% Ni steel plates exhibits sufficient brittle crack arrest fracture toughness for the application of LNG storage tank as a inner shell.

By PISA 2007, TIMSS 2011, Korean high school students had high academic achievement to science and mathematics, while they had low attitude. Prospective college students are increasingly avoiding natural science and engineering. Moreover, the opportunities to learn to computer science in middle and high school are disappeared rapidly. The necessity of STEAM program based on Physical computing arise under these situation. Therefore, we developed STEAM program and studied the effects of the program in 2012. The result showed that students' scientific interests and attitude, scientific problem solving ability, scientific creative problem solving ability, personality test for children, and satisfaction of school life were enhanced. This study is follow-up study for the same students who improved every domain of the measurements. They were administerd pre-test at start of 2012, post-test at end of 2012, and delayed post-test at the end of 2013, on same test. The result of the study showed that only attitude to Scientific Inquiry was enhanced, but there was no significant result on the other domain of the test in comparison with start of 2012. But this result demonstrate the effect of STEAM education conversely.

The purpose of this study was to investigate how teachers understand the principle of image formation of stars through a telescope. This study was conducted by using explanatory paper questionnaires given to 101 earth science teachers in the areas of Gyunggi province and Seoul. The questionnaires were cross-analyzed by three experts in earth science education. Result indicated that most of the participating teachers did not have systematic concepts about the process of making an image formed by a convex lens. Particulary, they did not sufficiently understand the concepts of an image and the functions of a screen. Furthermore, only 3% of the participants possessed the scientific concepts about the image formation principle of a star through the telescope. Most of the teachers seem to have non-scientific or alternative concepts about the image formation, which was only understanded with the fragmented characteristics about light and convex lens.

Objectives : The causative pathology of acute muscular pain cannot be defined in many patients. To evaluate the relations between mental state and acute muscular pain patients, the author surveyed symptom check list-90-Revision(SCL-90-R) in patients with acute muscular pain. Materials and Methods : From November 2004 to June 2005, a questionnaire including SCL-90-R was given to patients(52 persons) who visited our department for acute(<7days)muscular pain of neck(22 persons) or low back(30 persons). Fifty two patients(30 male, 22 female) completed SCL-90-R Results : 1. Mean values of T-scores on all 9 basic scales in the patients groups were within normal range. but T-scores SOM in the patients groups were significantly very higher than those in Normal groups(p<0.01). 2. The T-scores of SOM In low back pain patients were significantly higher than those in Normal groups(p<0.05). 3. There was no significant difference in all scales between acute muscular pain and L-spine HIVD patients groups. 4. There was no significant difference in all scales between acute muscular pain and general back pain patients groups. 5. There was no significant difference in all scales between male and female in the patients groups. Conclusion : It is concerned between T-scores on all 9 bas κ scales of SCL-90-R and acute muscular pain. Especially acute muscular pain of back has a relation to somatization of T-scores on all 9 basic scales of SCL-90-R.
