This study qualitatively explored the case of users utilizing multiple accounts on one social network service to create their own multiple spaces and different personas. The purpose of the study was to understand the behavior of people who use multiple accounts to express their identity online using Carl Jung's personality theory. We used in-depth interviews and the Zaltman metaphor elicitation technique (ZMET), targeting 19 people in their 20s and 30s who use more than one personal account on Instagram. Creating a shared consensus map using the configuration concept of ZMET derived six personas in relation to Instagram accounts. The motivations for the respondents' self-presentation associated with their personas and self-presentation types shown on Instagram were analyzed in terms of persona and fashion and subdivided into five dimensions: relationship management strategic presentation, self-monitoring presentation, competence demonstration presentation, anonymous presentation, and persona-centered presentation. Each respondent's persona and self-presentation formed by the Instagram account was analyzed.

The syndromes of left atrial isomerism and right atrial isomerism, called polysplenia and asplenia syndromes, respectively, consist of congenital heart defects with disturbances in normal left right isometry, and the etiology of atrial isomerism remains unclear. Right atrial isomerism is traditionally associated with severe cardiac defects, especially complete atrioventricular septal defect, transposition of great arteries, pulmonary atresia, and total anomalous pulmonary venous return. Recently, we encountered one case of asplenia diagnosed by prenatal ultrasonography. We report a case with brief review of the literatures.

The purpose of this study was to examine the species of 117 wooden elements which were used in the Daewungieon Hall (National Treasure No. 805, constructed in A. D. 1659) of Bukjijangsa Temple, Daegu, Korea. Pillars were identified as 5 red pines (hard pines; most likely, Pinus densiflora S. et Z.), 2 Cerris section of subgenus Lepidobalanus (deciduous oaks) and 3 Tsuga spp. Hwalju columns were 3 Abies spp. and 1 red pine. Head-penetrating ties were 8 red pines and 1 Cerris sp.; Pyeongbang, 3 red pines and 6 Cerris spp. Purlins were identified as 17 red pines, 16 Cerris spp. and 1 Tsuga sp. Angle rafters were 3 red pines and 1 Cerris sp., and end angle rafters, 2 red pines, 1 Zelkova serrata and 1 exotic hard pine. All of brackets (31 woods), jangyeo (4) and deot-chunyeo (2) were identified as red pines. As a whole, red pines (70.1%) and Cerris (22.2%) were major species used in the Daewungjeon Hall of Bukjijangsa Temple. Tsuga, Abies and exotic hard pines seem imported woods used for recent repairs.

Objectives: Objective: The diagnosis of ASCUS(atypical squamous cells of undetermined significance) and LSIL(low-grade squamous intraepithelial lesion) was introduced in 1988 by the Bethesda system for reporting cervical/vaginal cytologies. A significant proportion of women referred for colposcopy with low grade cervical cytologic abnormalities(ASCUS and LSIL) will have high grade cervical intraepithelial neoplasia(CIN II or CIN III) and therefore require adequate management. The purposes of this study were to evaluate the usefulness of high risk type HPV(human papillomavirus) DNA detection using PCR(polyerase chain reaction) in patients with low grade cervical cytologic abnormalities in the prediction of high grade CIN and invasive cancer and to determine the clinical triage in the management of low grade cervical cytologic abnormalities. Methods: We reviewed 18,942 cases of Papanicolau smears that were performed at our hospital from Jan. 1995 to Mar. 1999. Colposcopically directed biopsy or LLETZ(large loop excision of transformation zone) or hysterectomy were performed on 318 patients with abnormal PAP smears of low degree. HPV PCR testing of high risk types(16 and 18) was also performed on 115 patients. Results: Histologic outcome of ASCUS included 43 cases(38.4%) of high grade CIN and invasive cancer, and that of LSIL included 65 cases(47.5%) of high grade CIN and invasive cancer. In cases of high risk HPV type, 19 patients(73.1%) were at age over 30 years. A highly significant correlation was found between a positive test for high risk types of HPV and finding of high grade CIN and invasive cancer. Among 51 women with ASCUS, a positive test for high risk type had a sensitivity and specificity of 40.0% and 86.1%, and positive predictive value(PPV) and negative predictive value(NPV) of 54.5% and 77.5%, respectively. In 64 women with LSIL, a positive high risk type test was associated with sensitivity and specificity of 30.0% and 94.1%, and PPV and NPV of 81.8% and 60.4%, respectively. Conclusion: Our results suggest that high risk type HPV may be positively predictive of and may act as a surrogate marker for high grade CIN and invasive cancer in women with low grade cervical cytologic abnormalities. The management of women with a low grade cervical cytologic abnormalities should be active such as colposcopically directed biopsies.

YAG:Ce phosphor were prepared in a self-propagating high-temperature synthesis (SHS) using a 1.5Y2O3+2.5Al2O3+0.116CeO2+3.0KClO3+kCO(NH2)2+m(C2F4)n precursor mixture. The heat for the combustion propagation was provided by the reaction of a KClO3+CO(NH2)2+(C2F4)n mixture. Pure-phase YAG phosphor was synthesized at the combustion temperature of 1210℃ from k=3.6 mole and m=0.3 mole. The as-prepared YAG:Ce phosphor had a particle size of 2-10 ㎛. The addition of Teflon to the precursor mixture increased the YAG particle size and its luminescent intensity. The emission peak of the YAG phosphor was blue-shifted with an increase of Teflon concentration.

본 연구에서는 한국 사찰에 소재한 목패 23개를 대상으로 수종 및 연대를 조사하였다. 목패의 수종은 피나무속(Tilia spp.)과 은행나무(Ginkgo biloba)가 62%로 가장 많은 점유율을 나타내었고, 소나무류(redpine group, 8점), 오리나무류(Alnus group, 7점), 버드나무속(Salix spp., 6점), 배나무속(P yrus spp., 1점), 대나무류(1점), 잣나무아속(soft pines group, 1점) 순으로 조사되었다. 목패 10개에 대한 연륜연대 또는 방사성탄소연대 측정을 실시하였다. ‘수타사 목패’와 ‘개인소장 목패’의 C14 연대(95.4%)가 1471~1636년과 1483~1641년으로 측정되어 17C 전반 내지 그 이전에 제작되었을 것으로 볼 수 있었다. ‘순천 송광사 목패’는 C14 위글매치 결과, 95.4% 신뢰구간이 1658~1677년으로 산출되어 17C 중반에 제작된 것으로 밝혀졌다. ‘고성 옥천사 목패’의 연륜년대 측정 결과, 마지막 연륜에 1878년이 부여되어 19세기 후반에 제작된 것으로 나와 가장 늦은 시기의 것으로 밝혀졌다.

Objective: To determine whether the surgical procedures that lift and support the urethrovesical junction to its high position are effective in treating women with stress urinary incontinence and a negative Q-tip test. Methods: Thirty two women with a clinical and urodynamic diagnosis of stress urinary incontinence who had a negative Q-tip test[<30°Q-tip angle change on straining] were enrolled in this study. Among 32 patients, 21 patients had Burch operation and 11 patients had anterior repair. We obtained failure rate of Burch operation and anterior repair in patients with a negative Q-tip test and compared it with patients with a positive Q-tip test. Results: Ten of twenty one patients undergoing Burch operation[48%] and five of eleven patients undergoing anterior repair[45%] failed the operation, for overall failure rate of 47%. This rate was three and half times higher than that among with stress urinary incontinence and a positive Q-tip test who underwent the same procedures[P<0.05]. Conclusion: Women with stress urinary incontinence and no anatomic defect in the support of the urethrovesical junction should not undergo a traditional anti-incontinence surgeries because of their high failure rate.

본 연구에서는 추진기관 급속가열시험을 실시하여 그 특성을 분석 평가 하였다. 연소관은 카본 에폭시 복합재를 사용하였고 추진제는 둔감 특성을 향상 시켜주기 위해 HTPE 추진제를 사용하였다. 반응 형태를 정량적으로 판단하기 위해 음압 및 열유속 센서를 사용하였다. 급속가열 시험한 HTPE 모타들의 반응형태는 Type V 인 연소반응을 나타내었다. Fast cook-off test with rocket motors was performed and characteristics of the results were analyzed. The material of the motor case was carbon epoxy composite. The motor was loaded with HTPE propellants to improve the insensitive munitions characteristics. In the tests, sound pressure and heat flux sensors were used to determine the category of response according to the standard. The reaction response of all of the HTPE motors tested by fast cook-off was judged as Type V burning.

본 연구에서는 폴리머로 HTPE와 둔감가소제로 BuNENA를 적용하고, 산화제로는 AP, AN, 금속연료로 Al을 사용한 HTPE 둔감 유연 추진제에 대하여, 폭연성, 폭굉성 및 가열성에 대한 추진제 둔감성 적합 유무를 판단하기 위하여 UN Test Series 7의 EIDS 시험을 수행하였다. HTPE 둔감 추진제는 폭굉성 시험인 ELSGT, 폭연성 시험인 Friability 시험 및 가열성 시험인 EIDS 완속가열시험 모두 합격 기준을 만족하였다. In this study, HTPE insensitive propellant composed of HTPE/BuNENA binder, AP, AN and Al was tested to know whether to meet passing criteria for detonability, deflagrability and cook-off test of UN test series 7. HTPE insensitive propellant met all passing criteria for ELSGT, Friability test and EIDS slow cook-off bomb test.
