Objectives : According to the recent Korean National Police Agency report, rape victims were 17.1%, but sexual molestation victims were more than the rape victims by 78.0%. Despite many international reports about the occurrence of severe psychiatric symptoms in sexual molestation victims, there is no domestic research. Therefore in this study, we investigated psychiatric symptoms of sexual molestation victims, and we also compared it with psychiatric symptoms in rape victims. Methods : 58 women who visited Busan Smile Center within 3months after sexual violence were the study subjects. Questionnaire about sociodemographic and sexual violence related characteristics were retrospectively investigated. Of the psychiatric symptoms, Beck Depression Inventory(BDI), Beck Anxiety Inventory(BAI) for severity of depression and anxiety, and Impact of Event Scale-Revised(IES-R) to check the presence of posttraumatic stress disorder(PTSD) symptoms were used. Results : Of 58 sexual violence victims, sexual molestation victims were 36(62.1%) and rape victims were 22(37.9%). In sexual molestation victims, 80.6% had more than moderate severity of depression, 83.3% had more than moderate severity of anxiety, and 94.4% had significant scores at PTSD screening test. Compared with rape victims' psychiatric symptoms(each 95.5%, 95.5%, 95.5%) there were no significant difference. Conclusions : The majority of sexual molestation victims were also accompanied by depression, anxiety and PTSD symptoms as rape victims. There results suggest that appropriate assessment and early treatment for psychiatric symptom must be made in the early stage of injury in sexual molestation victims.

This study was conducted to examine the association between the myosin heavy chain 3 (MYH3) in 6-bp deletion variant genotypes and meat color traits in a crossbred pig population Landrace and Jeju native black pigs (JNBP). The longissimus dorsi, semimembranosus, triceps brachii and biceps femoris muscle from each carcass were used for the analysis of meat color traits. A total of 187 pigs and three meat color traits, CIE L^* (lightness), CIE a^* (redness), and CIE b^* (yellowness), were analyzed. All experimental pigs were successfully genotyped for the MYH3 6-bp deletion variant using Polymerase chain reaction (PCR) analysis. We detected three MYH3 6-bp deletion variant genotypes qq, Qq, and QQ with 0.091, 0.551 and 0.358 genotype frequencies, respectively. Compared to qq homozygotes, the MYH3 6-bp deletion QQ genotype animals showed a higher levels of the meat colors traits CIE L^* (lightness), CIE a^* (redness), and CIE b^* (yellowness) in longissimus dorsi (p>0.05, p<0.001, p<0.001), semimembranosus (p>0.05, p<0.001, p<0.001), triceps brachii (p<0.001, p<0.001, p<0.001), and biceps femoris (p<0.01, p<0.001, p<0.001), respectively. The QQ genotype pigs was associated with increasing meat color traits in the crossbred between Landrace and JNBP. Our findings suggest that the MYH3 6-bp deletion variant genotypes can be used as valuable genetic markers for JNBP-related breeding programs to improve meat quality and control meat color traits.

The purpose of this study was to identify the amount of alcohol and drinking frequency among high school students based on social alcohol drinking supply. The data was on 161 drinkers aged between 16 and 19 from 21 high schools across the country using a questionnaire of the International Alcohol Control(IAC) Study, which was developed in 2012. Results show that the higher the number of social suppliers offering alcoholic beverages to high school students, the greater the consumption of alcohol per episode(59.433 g for one person, 113.40 g for two, and 133.56 g for three or more people). On the other hand, alcohol consumption among 'Honsul' people, a group that drinks alone without a social drinking supplier, was 167.84 grams, higher than that of groups that receive social drinking services. As a social drinking supplier for teenagers, drinking was the highest by their father (29.3 %), while friends (25.0 %) and mothers (20.7 %) were the main drinking suppliers. In particular, the provision of drinking due to father(𝛽=-.32, t=3.55, p<.01) and mother(𝛽=.22, t=2.71, p<.01) showed statistical significance as a factor in increasing the frequency of providing social drinking in adolescents. On the other hand, partner/boy or girl friend (𝛽=-.23, t=-2.73, p<.01) was a factor in reducing the frequency of alcohol provision. Friends(𝛽=.24, t=3.02, p<.01) and senior-junior schoolmates(𝛽=.16, t=2.04, p<.05) were the factors that increase the total alcohol intake of adolescents. This is due to the increase in the frequency of alcohol provision. This suggests that alcohol harm education should be expanded from students to parents, considering the role of parents as a social drinking supplier and the link between high alcohol intake among teenagers due to senior-junior friends and schoolmates.

Purpose : The purpose of this study is to verify the accuracy of dose delivery according to the pitch and roll rotational setup error with 6D robotic couch in Intensity Modulated Radiation Therapy (IMRT) for pelvic region in patients. Materials and Methods : Trilogy(Varian, USA) and 6D robotic couch(ProturaTM 1.4, CIVCO, USA) were used to measure and analyze the rotational setup error of 14 patients (157 setup cases) for pelvic region. The total 157 Images(CBCT 78, Radiography 79) were used to calculate the mean value and the incidence of pitch and roll rotational setup error with Microsoft Office Excel 2007. The measured data (3 mm, 3%) at the reference angle ($0^{\circ}$) without couch rotation of pitch and roll direction was compared to the others at different pitch and roll angles ($1^{\circ}$, $1.5^{\circ}$, $2^{\circ}$, $2.5^{\circ}$) to verify the accuracy of dose delivery by using 2D array ionization chamber (I'mRT Matrixx, IBA Dosimetry, Germany) and MultiCube Phantom(IBA Dosimetry, Germany). Result from the data, gamma index was evaluated. Results : The mean values of pitch and roll rotational setup error were $0.9^{\circ}{\pm}0.7$, $0.5^{\circ}{\pm}0.6$. The maximum values of them were $2.8^{\circ}$, $2.0^{\circ}$. All of the minimum values were zero. The mean values of gamma pass rate at four different pitch angles ($1^{\circ}$, $1.5^{\circ}$, $2^{\circ}$, $2.5^{\circ}$) were 97.75%, 96.65%, 94.38% and 90.91%. The mean values of gamma pass rate at four different roll angles ($1^{\circ}$, $1.5^{\circ}$, $2^{\circ}$, $2.5^{\circ}$) were 93.68%, 93.05%, 87.77% and 84.96%. when the same angles ($1^{\circ}$, $1.5^{\circ}$, $2^{\circ}$) of pitch and roll were applied simultaneously, The mean values of each angle were 94.90%, 92.37% and 87.88%, respectively. Conclusion : As a result of this study, it was able to recognize that the accuracy of dose delivered is lowered gradually as pitch and roll increases. In order to increase the accuracy of delivered dose, therefore, it is recommended to perform IGRT or correct patient's position in the pitch and roll direction, to improve the quality of treatment.

Purpose : The purpose of this study is to compare the plan quality of volumetric-modulated arc therapy (VMAT) and intensity-modulated radiation therapy (IMRT) for the treatment of orbital lymphoma. IMRT, partial single arc(SA) and partial-double arc(DA) VMAT plans for four patients with orbital lymphoma treated at our institution were used for this study. Conformity Index(CI), Paddick's Conformity Index(PCI) and Homogeneity Index(HI) of planning target volume(PTV) were used to evaluate dosimetric quality of each plan. The Monitor Unit (MU), treatment time and dose of ipsilateral lens from each type of plan were measured for comparison. Materials and Methods : The CI of PTV for IMRT, SA and DA were measured as 0.88, 0.86, 0.92. The PCI of DA was the lowest as 1.33. Also HI of DA was the lowest in measured plans as 1.15. Mean dose of lens, lacrimal gland, optic chiasm, the opposite optic nerve and both orbit was analyzed with V30, V20, V10, V5. The result showed that the lowest dose in IMRT highest in SA in opposite lens, lacrimal gland, optic nerve, orbit. Results : Treatment time and average MU of IMRT was about three times higher than SA. Conclusion : Considering the superior plan quality as well as the delivery efficiency of VMAT compared with that of IMRT, VMAT may be the preferred modality for treating orbital lymphoma.

The aims of this work were the identification and the classification of fresh lubricants and used engine oils of vehicles for the application in forensic science field-80 kinds of fresh lubricants were purchased and 86 kinds of used engine oils were sampled from 24 kinds of diesel and gasoline vehicles with different driving conditions. The sample of lubricants and used engine oils were analyzed by GC/MS. The Bayesian model technique was developed for classification or identification. Both the wavelet fitting and the principal component analysis (PCA) techniques as a data dimension reduction were applied. In fresh lubricants classification, the rates of matching by Bayesian model technique with wavelet fitting and PCA were 97.5% and 96.7%, respectively. The Bayesian model technique with wavelet fitting was better to classify lubricants than it with PCA based on dimension reduction. And we selected the Bayesian model technique with wavelet fitting for classification of lubricants. The other experiment was the analysis of used engine oils which were collected from vehicles with the several mileage up to 5,000 km after replacing engine oil. The eighty six kinds of used engine oil sample with the mileage were collected. In vehicle classification (total 24 classes), the rate of matching by Bayesian model with wavelet fitting was 86.4%. However, in the vehicle's fuel type classification (whether it is gasoline vehicle or diesel vehicle, only total 2 classes), the rate of matching was 99.6%. In the used engine oil brands classification (total 6 classes), the rate of matching was 97.3%.

The purpose of this study was to analyze the temperament of the science gifted and to identify a relationship between temperament and test-anxiety of the students. The participants were composed of 92 middle school the science gifted who had been educated for the gifted in science educational institution of university and 97 general students in their first-year of middle school. A revised dimensions of temperament survey (DOTS-R) was used for data collection. This study revealed that the science gifted displayed higher concentricity, persistence, and approach-temperament than those of general students. On the other hand, general students were higher than the science gifted at activity, flexibility and positive mood. In the analysis of superior temperament, the science gifted were superior to general students in persistence, while general students were superior to the science gifted in flexibility. The Results of correlation with temperament and test-anxiety was as following. There was close correlation between approach-temperament and test-anxiety of the science gifted. Persistence was the same. While general students were not close correlation between concentricity and test-anxiety. Also science gifted and general students was close correlation between activity and test-anxiety. This mean that activity brings about a disturbing factor of test-anxiety. According to the results of superior temperament frequency analysis, persistence is superior temperament of the science gifted. While flexibility was superior temperament of general students. This study expects to making the use of providing appropriate teaching and learning strategies for the science gifted.

This study starts from the hypothesis that the information society has affected the layman's interpretation and production of content. Specifically, the manner and contents of communication concerning the landscape of Soonyoo-do Park in blogs are surveyed and the possibilities and limitations of this phenomenon are discussed. The following topics are dealt with. Firstly, what is the landscape of Seonyoodo Park as captured by bloggers? What type of landscape do bloggers respond to? Secondly, what is the unique way that bloggers capture and interpret the landscape? Thirdly, What are the possibilities and limitations discovered from the landscape as captured and interpreted by bloggers? Thus, 1,000 blog posts concerning Soonyoo-do Park, as culled from the Internet, were categorized into three areas, First are blog posts browsed by keywords such as 'photo', 'a photographer's visit', 'a good p1ace for taking photos', and 'landscape'. These are focused on the visual aspects of the landscape. The second category is posts under the keywords 'domestic travel', 'Seoul travel', 'travel', and 'recommendation'. They contain introductory information on Seonyoodo Park; that is, they focus cm the more utilitarian functions of Seonyoodo Park as a place. The third one is posts that record personal experiences. The subjects for photography are the bloggers themselves and their companions. As a result of studying the way bloggers deal with landscape, it was found that first, people have developed the ability to capture the landscape and interpret the landscape actively and independently. This process can be regarded as the reproduction of landscape and place. In addition, the recording of their appreciation and feeling overlaps with evaluation and assumption. One negative aspect, however, is that many bloggers dramatize and repeat similar scenes. This can be seen as a make-up of image. The limitations of this study include difficulty in interpretation because blogs, which are the objects of this study, are very subjective and personal. In addition, it was not easy to categorize posts because there were diverse images and a broad range of writing. Nevertheless, practitioners of landscape architecture should continue to monitor and use one-person media like blogs, because the relationship between modern man and the landscape can be better understood through them.

Digital Radiography (DR) has rapidly developed in megavoltage X-ray imaging (MVI). Thus, a very simple and general quality assurance (QA) method is required. The purpose of this study was to evaluate the modulation transfer function (MTF), the noise power spectrum (NPS) and the detective quantum efficiency (DQE) for MVI using general QA method and computed radiography (CR) device. We used tungsten edge block with $19{\times}10{\times}1cm^3$ thickness and 6MV energy. For detector, CR-IP (image plate), CR-IP-lead, the CR-IP-back (lanex TM fast back screen), CR-IP-front (lanex TM fast front screen) were used and pre-sampling MTF was calculated. The MTF of CR-IP-front showed the highest value with 1.10 lp/mm although the CR-IP showed the only 0.70 lp/mm. The best NPS was observed in CR-IP front screen. According to the increase in spatial frequency, our results showed that DQE was approximately 1.0 cycles/mm. The present study demonstrates that the QA method with our home-made edge block can be used to evaluate MTF, NPS and DQE for MVI.
