The purpose of this study was to investigate the degree of link with internet media and a internet addiction disposition of adolescents. The subjects were 500 students attending to middle and high schools consisted of male and female. The instruments were "the questionnaire on the present conditions of internet use" consisted of 14 items(Cronbach's α=.71) and "the internet addiction rating scale" consisted of 20 items(Cronbach's α=.73). These questionnaire were revised by this researcher. For data analysis, chisqure and ANOVA were used. The main results were as follows. First, a boy students and the vocational high school and the middle school each have more negative response than a girl students and the humanistic high schools in the present conditions of internet use and the judgement on a harmful object of internet space. Second, a boy students have higher than a girl students in an internet addiction disposition. Third, an internet addiction related with the times link with internet, the type of internet game, and the content of internet space(a lustful and violent objects). The various methods for the prevent with the internet addiction of adolescents discussed with based on the previous studies.

Purpose : The purpose of this study was to compare the postoperative success and stability of arthroscopically assisted anterior cruciate ligament(ACL) reconstructions using the central one third bone patellar tendon bone(BPB) autograft versus a quadrupled semitendinosus/gracilis(ST) autograft in patients with "isolated" ACL tears. Materials & Methods : A strict criteria to identify isolated ACL tears was used which included : no previous surgery, no other ligamentous injury, no history of patellofemoral symptoms, no patellofemoral malalignment, no meniscal pathology, no chondromalacia or chondral injury and no limitation of motion of the injured knee. 30 patients (15 BPB, 15 ST) with a mean age of 27.4 years were available for a mean follow up of 18 months (between 12 months and 26 months). Preoperatively, there was no significant difference between the two groups with respect to age, sex and degree of laxity. Results : Postoperatively, we couldn't find significant differences between the two groups with respect to subjective Lysholm score, objective laxity including Lachman test, pivot shift test and KT-2000 measurements. Mean side to side difference of KT-2000 scores at 20lbs were 1.5mm for the BPB group and 1.4mm for the ST group. Positive Lachman test was found in 26.7% and 33.3% and positive pivot shift was found in 20% and 33.3% of the patients in the BPB and ST groups, respectively. Anterior knee pain (33.3%) was more common in the BPB group. There were 80% of the patients in both groups above nearly normal grade according to the IKDC grade. Conclusions : In patients with "isolated" ACL tears, the overall results, ligamentous stability for the patellar tendon and the quadrupled semitendinosus/gracilis were comparable. We consider that the quadrupled autogenous hamstring tendon is a good alternative substitute in ACL reconstruction together with the bone patellar tendon bone.

The purpose of this study is to examine if there is any difference due to the general characteristics of middle school students who are beneficiaries of educational welfare services and a special quality of use about educational welfare services. Additionally, the examination has been performed to understand the relationship that exists between the satisfaction about educational welfare services, and adaptation to school life and self-respect of middle school students who are beneficiaries of educational welfare services. The results of the study showed meaningful higher scores by male students than female students only in the environmental adaptation area among lower areas in school life adaptation due to sex. Due to school year, third-year students showed meaningful high scores in school life adaptation. The satisfaction about programs in each area of educational welfare services of middle school students who are beneficiaries of educational welfare services showed a meaningful static relationship with school life adaptation. The inspection of the relationship between satisfaction about educational welfare services and 5 lower areas of school life adaptation showed statistically meaningful results in the order of adaptation to the teacher, adaptation to the environment and adaptation to the class, which are lower areas. The examination on the relationship between self-respect and adaptation to school life showed that self-respect has a static relationship with all lower areas of school life and overall school life adaptation. However, no meaningful relationship was shown between the satisfaction about educational welfare services and self-respect. Also, it was found that the factors of grade, self-respect, the number of service utilization have an effect on school life adaptation. This study has some limitations. But in this study, which is different from other studies which dealt with students who had used partial areas of educational welfare services, students who were using all 4 areas of educational welfare services were selected as subjects. In addition, this study is significant in that basic data has been offered for establishment of a policy on educational welfare services in middle schools in the future.

Plain 0.5% bupivacaine and hyperbaric 0.5% tetracaine were compared for spinal anesthesia in 40 patients undergoing operation of lower extremities. Lumbar puncture was performed with a 22 gauge spinal needle with the patient in the lateral recumbent position. The third lumbar interspace was chosen for the puncture, when a free flow of clear CSF was obtained, the local anesthetic solution (2.5ml of 0.5% bupivacaine or 2.0ml of hyperbaric 0.5% tetracaine) was injected at a rate of 0.1ml/sec without barbotage. After injection of anesthetics, clinical features were observed and compared between the two groups. The results were as follows : 1. The two groups were well matched for age, sex, height and weight. 2. In both groups, sensory block to $T_{12}$ dermatome was obtained within 4 minutes, mean maximal level of analgesia was $T_{6-7}$, and the mean time for maximal level was around 20 minutes. 3. The onset times of motor block were similar in both groups and complete motor block was obtained in all cases within 20 minutes. 4. The duration of analgesia above the $T_{12}$ dermatome was 3 hours, postoperative analgesia was 7 hours. These values were significantly prolonged than those of the tetracaine group(p<0.05). 5. The changes in systolic pressure in the bupivacaine group were significantly less than those of the tetracaine group(p<0.05). 6. The complications after spinal anesthesia were headache, numbness, urinary retention and backpain, and were no significant difference in both groups. From the obtained results, we concluded that plain 0.5% bupivacaine was a relatively satisfactory agent for spinal anesthesia for operation of lower extremities. The time of onset, height of block and the complications of postoperative period were similar in both groups. The advantages of plain 0.5% bupivacaine were less hypotension and long duration of analgesia.

The purpose of this research was to empirically explore the association between exposure to news of the nth Room Case, indirect trauma, and beliefs about the world among adults in their 20s. A total of 228 adults in their 20s participated in an online survey designed to study the association above. Analysis using SPSS 25.0 showed that participants who were exposed to more related news immediately after the nth Room case was revealed experienced a higher level of indirect trauma. Furthermore, indirect trauma fully mediated the relationship between exposure to the news of the nth Room Case and beliefs about the world. This study empirically demonstrated the impact of news exposure on beliefs about the world through indirect trauma, suggesting that, like disasters, sex crimes can cause indirect trauma to third parties through the news. However, this study was limited to adults in their 20s, and most of the participants were women; therefore, future studies using samples representing demographically more diverse groups are needed. Future research could also examine the possibility of emotional contagion mediating or moderating the relationship between news exposure and indirect trauma.

Fundamental direction of the seventh education curriculum aims to nurture active and creative Koreans for globalized and information-oriented society of 21 century, and emphasizes the importance of career education identifying its subsections that are practices of student-focused education of aptitude, ability and career. Hence, as a clear targeting of career objective from elementary school through relevant career education enables them to recognize appropriate career for themselves, the basis of self- actualization and social contribution must be settled. This paper seeks to identify the relationship between career awareness and self-esteem by examining and analysing differences of sex, region and level. This study selected 536 samples from 4th and 6th year elementary school students in C city and S town of Chungcheong province. Career awareness test and self-esteem test is used as a measurement, statistical process control (SPC) of career awareness and self-esteem (M, SD, r) is made for each variable, and the significance was tested. The result of this research can be summarized as follows: First, generally there is very significant regional differences of career awareness (F=16.817, p<.001), which contains that urban children has higher career awareness (M=120.22) than that of rural children (M=113.87). In subsections of career awareness, self-esteem of urban children is higher than that of rural children, and the attitude & for career and values of girls is higher than that of boys. In terms of the career planning, urban children and 6th year students are higher than rural children and 4th year students. Second, self-esteem generally has very significant regional difference (F=12.123, p<.01), which contains that the self-esteem of urban children (M=106.50) is higher than that of rural children (M=101.80). In comparison of different forms, a very significant difference is as much as p<.01 level (F=11.046), which contains 4th year students (M=105.63) have higher self-esteem than 6th year students (M=102.05). In subsections of self-esteem, gross self-esteem and social self-esteem of urban children are higher than rural children. In terms of family self-esteem, urban children and 4th year students have higher figure than rural children and 6th year students. In school self-esteem, 4th year students had higher level than the 6th. Third, the career awareness and self-esteem are generally related as r= .50, it was very significant at p<. 001 level. All subsections of career awareness had positive relationships except the school self-esteem. According to the result, rural children had relatively low career awareness and self-esteem. This is presumably due to relatively poor circumstances for rural children, comparing to that of urban children. Therefore rural elementary schools should try to let them have appropriate career awareness by associating with family, school and local society to expand the opportunity of experiences for the self perception of aptitude, nature and interest. In addition, we have to strive for the whole-minded education increasing the self-esteem of rural children and giving them positive thinking through career counselling, personal counselling and group counselling.

The tonsillitis has long been one of the most common disease in the otolaryngologic field. Peritonsillar abscess occurs when bacterial infection of the tonsil spreads to the potential peritonsillar space deep behind the tonsil, and it usually occurs in patients with recurrent tonsillitis or in those with tonsillitis who have been inadequately treated. We studied retrospectively 71 patients who had been diagnosed as acute tonsillitis and 82 patients who had been diagnosed as peritonsillar abscess and had admitted in our department of the Ulsan Dong Kang Hospital from January, 1995 to September, 1997. Especially in the bacteriologic studies, we compared acute tonsillitis and peritonsillar abscess with chronic tonsillitis. The following results were obtained： 1) The sex distributions of acute tonsillitis were 47 males(66%) and 24 females(34%) cases, but 57 males(70%) and 25 females(30%) in cases of peritonsillar abscess. There were predominant in male and frequently affected in second and third decades in 53 cases(76%) of acute tonsillitis and 56 cases(68%) of peritonsillar abscess. 2) It was same found in each season. 3) The duration from onset of symptom to visit in our department was 3.92 days in cases of acute tonsillitis and 5.95 days in cases of peritonsillar abscess in average 4) The major symptoms were sore throat, swallowing difficult. And others were fever, fatigability, dysarthria, trismus, headache, otalgia. 5) Among the 71 cases of acute tonsillitis and 82 cases of peritonsillar abscess, most temperature of patients at visit were 36.6-37.5 $^{\circ}C$ in each 36 cases(51%), 57 cases(70%). 6) In each disease, 35 cases(47%), 45 cases(75%) consisted of single infection and 39 cases(53%), 15 cases(25%) consisted of mixed infection. In acute tonsillitis, 111 strains were isolated from 74 cases, the most common strain was 69 strains(62.2%) of $\alpha$-hemolytic streptococci. In the peritonsillar abscess, 77 strains were isolated from 60 cases, the most common strain was 49 strains(63.6%) of $\alpha$-hemolytic streptococci. In chronic tonsillitis, 563 strains were isolated from 382 cases, the most common strain was 334 strains(50.3%) of $\alpha$-hemolytic streptococci. 7) In acute tonsillitis and peritonsillar abscess, the most common leukocyte levels were reported with 10, 000-15, 000/$\mu$L in 23 cases(32%). The CRP levels were reported with abnormal findings in 61 cases(97%), 63 cases(95%) above 0.3 in each cases.

Data and pedigree information for Lori-Bakhtiari sheep used in this study were 6,239 records of lamb mortality from 246 sires and 1,721 dams, collected from 1989 through 2007 from a Lori-Bakhtiari flock at Shooli station in Shahrekord. The traits investigated were cumulative lamb mortality from birth up to 7 days, up to 14 days, up to 21 days, and up to 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 and 12 months of age. The models included fixed factors that had significant effects and random direct genetic, maternal genetic and maternal permanent environmental effects. Variance components were estimated using the restricted maximum likelihood procedure applying three animal models with and without maternal and common environmental effects. The overall mean of cumulative lamb mortality rate was 22.95% from birth to 1 year of age, while the overall mortality rate up to 3 and from 3 to 6 months of age was 6.14% and 12.76%, respectively. The mortality rate after 6 months of age declined as the lambs grew older. The age of dam had no important effect on lamb mortality. The type of birth was more important during the preweaning period than at later ages, and lamb mortality rate was higher in twins. The year of birth, month of birth and sex of lamb significantly (p${\leq}$0.01) affected the cumulative lamb mortality rate at all ages. The least square mean of mortality during the final one-third of the lambing period was higher than the first and middle onethird of the lambing period. Male lambs were found to be at a higher risk of mortality than females. Birth weight of the lamb had a highly significant (p${\leq}$0.01) effect on lamb mortality at all ages as a quadratic regression. Direct and maternal heritability estimates of lamb mortality ranged from 0.01 to 0.13 and 0.01 to 0.05, respectively. Direct heritability increased with age of lamb, while maternal effects (genetic and common environmental) were important in the preweaning period. These results indicate that lamb mortality can be reduced first through farm management practices and secondly by genetic selection. Both animal and maternal effects should be considered in breeding programmes for reducing lamb mortality at preweaning.

The purpose of study is to identify the relation between pain level and perceived family support and quality of life in musculoskeletal patient with chronic pain. The subjects for the study consist of 155 patients with musculoskeletal pain that received medical treatment in hospital or by attending hospital in Chonju. The data were collected during the period from August 5 to August 14, 1998 by means of interviews with structured questionnaire. Data analysis was done by descriptive statistics. t-test, ANOVA, Pearson's correlation, Regression. Cronbach alpha using the SAS program. The result of this study were as follows : 1. The mean score of pain was 8.02, family support was 3.88 and quality of life was 3.07. 2. Hypothesis : The first hypothesis that 'The lower pain level is, the higher quality of life is' was accepted (r=-.2178, p= .0065). In addition, pain level of musculoskeletal patient with chronic pain provided predicted 4.7%(F=7.619, P= .0065) of quality of life. The second hypothesis that 'The higher perceived family support is, the lower pain level is' was rejected (r=-.0376, p= .6425). The third hypothesis that 'The higher perceived family support is, is higher quality of life is' was accepted (r= .3212, p= .0001). In addition, perceived family support of musculoskeletal patient with chronic pain provided predicted 10.31% (F=17.597, p= .0001) of quality of life. 3. General characteristics related pain were age(F=6.85, p= .0001),educational-level(F=9.29, p= .0001), occupation(F=5.81, p= .0037), marriage status(F=8.09, p= .0005), family numbers(F=5.73, p= .001), benefits of medical care(F=4.09, p= .0019), pain period(F=9.52, p= .0001), part of pain(F=2.33, p= .0352), pain period(F=3.08, p= .0181). 4. General characteristics related pain were sex(t=3.20, p= .0017), support sources(t=3.26, p= .0014), pain period(F-4.52, p= .0018). 5. General characteristics related pain were religion(t=3.11. p= .0022), benefits of medical care(F=3.61, p= .0293), pain duration(F=3.03, p= .0195). In conclusion, perceived family support in musculoskeletal patient with chronic pain is an important factor that can improve their quality of life. Therefore, nurses must establish nursing plan included patient's family when nurses carry out nursing intervention and education for patient so that a patient promote quality of life by maintaining optimal wellbeing.

The purpose of this study is to identify the trajectories in the use time of children from community children centers and to examine the predictive factors and developmental factors related to each trajectory. The data were derived from the second stage of the Community Children Center Panel Survey using from the first wave (2014) to the third wave (2016). A total of 606 samples were selected from the forth to sixth grades of elementary school. Latent class growth model was employed to identify the trajectories, and the multinominal logistic regression and the logistic regression analysis were used to examine predictive factors and developmental factors. Main results indicated that three types of trajectory were identified: high using group, low using group, and high initial using-rapid declining group. Sex, parental supervision, and use duration were found to be significant predictors. Regarding developmental factors, children who constantly use the community children centers were more likely to increase academic performance and school adaptation. However, no significant results were found for aggression and delinquent behaviors. Based on these findings, this study have suggested the future direction of the community children center.
