완전 무치악 환자에서 임플란트를 이용한 보철 수복을 계획하는 경우 임상의는 많은 어려움과 직면하게 된다. 임플란트를 이용한 고정식 보철물로 수복하려는 경우 높은 치료 비용과 장기간의 치료 기간뿐만 아니라 고도로 흡수된 치조골로 인해 추가적인 수술을 동반해야 하는 경우가 많다. 또한 임플란트 피개의치 제작 시에는 수복물을 위한 악간 공간의 부족이 문제가 될 수 있다. 본 연구에서는 최근 연구되고 있는 임플란트를 지대치로 이용한 가철성 수복 증례의 하나로, 상악 완전 무치악 환자에서 전치부의 소수 임플란트 식립 후 이를 지대치로 하는 후방 연장 국소의치 수복을 수행하였다. 이는 치조골 이식 등의 부가적인 수술 가능성을 줄여 치료 기간을 단축시키며, 고령의 환자에게도 비교적 받아들이기 쉬운 치료법이 될 수 있다. 본 증례에서 이를 이용하여 환자에게 기존의 보철물 양식과 유사한 보철 수복을 제공하여 빠른 적응과 저작 효율 및 심미성을 회복하였으며, 만족할만한 치료 결과를 보여주었다. Clinicians are faced with many difficulties when planning prosthodontic restorations with implants in a complete edentulous patient. When planning fixed implant prosthetics, it is often necessary to have additional surgery due to highly reduced alveolar bone, as well as high treatment costs and long-term treatment durations can be required. In addition, lack of interocclusal space can be a problem when planning implant supported overdentures. In this study, we planned to place a small number of implants on the anterior maxilla and used them as the abutments for distal-extension removable partial dentures on the posterior side in a maxillary fully edentulous patient. This would reduce the possibility of additional invasive operations such as alveolar bone graft, shorten the treatment time, and be relatively easy for elderly patients to burden. In this case, the patient was provided with a distal-extension removable partial denture and anterior implant fixed prostheses, which was similar to the previous one, and showed good adaptation, and chewing efficiency and esthetics was recovered.

Effects of Brief Advice from Family Physicians on the Readiness to Change of Korean Male At-risk Drinkers

권보라,김종성,김성수,정진규,김민영,송인규,윤광미 대한가정의학회 2012 Korean Journal of Family Medicine Vol.33 No.3

Background: This study examined the effects of the method of delivery of brief advice on the readiness to change in at-risk drinkers. Methods: The participants were 103 at-risk male drinkers who visited Chungnam National University Hospital for general health examinations. Baseline data on drinking behavior, readiness to change drinking behavior, and sociodemographic characteristics were obtained from a questionnaire. Family physicians gave two minutes of advice by telephone or inperson. The brief advice comprised a simple statement that the patient’s drinking exceeded the recommended limits and could lead to alcohol-related problems. It also included advice to moderate one’s drinking. One month later, the readiness to change was assessed again by telephone. The improvement in the readiness to change according to each method of delivery was investigated. Results: Initially, among the 58-patient in-person advice group, 12 patients were in the precontemplation stage, 38 in the contemplation stage, and 8 in the action stage. One month after the advice was given to the patients, the distribution had changed significantly (P < 0.001) to 1, 21, and 36 patients, respectively. Among the 45-patient telephone advice group,7 patients were in the precontemplation stage, 32 patients were in the contemplation stage, and 6 patients were in the action stage before the advice. The distribution had changed significantly (P < 0.001) to 1, 17, and 27 patients, respectively,1 month after the advice. Conclusion: These results suggest that brief advice by family physicians is effective in improving the readiness to change of at-risk drinkers, regardless of the delivery method.

Purpose: Japanese data indicates an incidence of persistent primitive olfactory artery (PPOA) of 0.14%. We studied the incidence of PPOA and associated cerebral vascular variation or anomalies in Korea. Materials and Methods: We retrospectively reviewed cranial magnetic resonance angiography (MRA) and computed tomography angiography (CTA) images of a total of 9841 patients of our institution. The diagnostic criterion of PPOA is extreme anterioinferior course of the proximal anterior cerebral artery, with a hairpin turn of the lateral projection. Results: We found 29 cases (0.29%) with PPOA. The PPOA location was on the left in 19 cases, bilateral in 3 cases, and on the right in 7 cases. An aneurysm was found at the hairpin turn in 2 patients. There were aneurysms in other sites in 3 cases. There were hypoplasia of anterior cerebral artery in 3 cases, and fenestration of intracranial artery in 1 case. Conclusion: In Korean populations, the incidence of PPOA found in MRA and CTA was twice as high as that shown in the previous Japanese data. Within Korea, left side laterality is more common than right side or bilalterality. Aneurysmal dilatations at the hairpin turning point and aneurysms at other sites were found, and other vascular variations were observed in several cases.

본 연구는 기후변화와 관련하여 양묘과정에서 온도와 강수 변화에 따른 주요 침엽수의 생존 및 생장 특성 변화를 알아보고자 수행하였다. 소나무와 낙엽송 노지묘(1-0)를 대상으로 대조구 기준 3℃의 온도를 상승시키거나 ±40%의 강수를 조절한 6처리 생육환경[온도 2처리(대조: TC, 증가: TW) × 강수 3처리(대조: PC, 감소: PD, 증가: PI)] 실외 실험구를 조성하였으며, 생존율, 근원경, 묘고, 물질생산량 및 묘목품질지수 변화를 조사하여 이원분산분석을 수행하였다. 소나무는 온도와 강수 처리에 따른 생존율 차이가 없었지만, 강수가 증가할수록 묘목품질지수가 낮아지는 경향을 보였다. 낙엽송은 온도상승과 강수 감소에 따라 고사율이 증가하였으며, 묘목품질지수는 두 요인 간 상호작용을 보이면서 온도대조-강수증가 처리구에서 가장 낮게 나타났다. 따라서 양묘과정에서 소나무는 강수 증가, 낙엽송은 온도 증가 또는 강수 감소에서 낮은 묘목 생산량과 품질이 예상되며, 기후변화에 따른 두 수종의 특이적 민감도를 확인할 수 있었다. 향후 지구온난화와 가뭄·폭우 등의 강수 변화에 의해 수종별 묘목 생존과 품질의 변화가 예상되기 때문에 각 수종의 생육 반응 특성에 따른 적합한 양묘시업 대응 전략이 필요할 것으로 판단된다. This study aimed to investigate the effects of climate change on the survival and growth performance of Pinus densiflora and Larix kaempferi seedlings using open-field experimental warming and precipitation manipulation. We measured the survival rate, root-collar diameter, and height, and then calculated the seedling quality index (SQI) of 2-year-old seedlings under 6 treatments [2 temperatures (TC: Control; TW: Warming) × 3 precipitation manipulations (PC: Control; PD: Decreased; PI: Increased)] and performed a two-way ANOVA to test for differences.The air temperature of the warming plots was 3°C higher than that of the control plots, while the precipitation manipulation plots received ±40% of the precipitation received by the control plots. Temperature and precipitation treatments did not significantly affect the survival rate of P. densiflora; however, the SQI of P. densifloradecreased with increasing precipitation. In contrast, the mortality rate of L. kaempferi increased with increasing temperature and decreasing precipitation. Furthermore, in L. kaempferi, TC × PI treatment resulted in the lowest SQI with a significant interaction effect observed between the two factors. In summary, low seedling production and quality should be expected in P. densiflora as precipitation increases and in L. kaempferi as temperature increases or precipitation decreases. These results indicate species-specific sensitivities to climate change of two plant species at the nursery stage. With the occurrence of global warming, the frequencies of drought and heavy rainfall events are increased, and this could affect the survival and seedling quality of tree species. Therefore, it is necessary to improve nursery techniques by establishing new adaptation strategies based on species-specific growth performance responses. 1

Background: Korean standard series (KSS) have not changed for 20 years. Moreover, the Korea Food and Drug Administration has suspended import licensing of Cosmetic series (Chemotechnique^Ⓡ). Objective: To analyze trends in the positive rates of allergens in patch test using KSS and present a literature review on the comparison of the results those of European baseline series (EBS) and North American Contact Dermatitis Group (NACDG) screening series. Methods: Epidemiologic findings and the positive rate of KSS allergens were analyzed from patients who visited the Department of Dermatology in Ewha Womans University Mokdong Hospital between 1998 and 2018. Literature reviews were conducted on the comparison of the results with those of the 2015∼2016 NACDG, 2013∼2014 ESSCA, and standard antigens in K-camp. Results: The positive rates of KSS allergens from 126 patients in 2018 were compared with those from 184 patients during 1998 to 2007. The top 3 allergens in the two study periods were common; nickel sulfate, cobalt chloride, and potassium dichromate. Remarkably, the positive rates for balsam of Peru and paraben mix increased from 7.1% to 17.5% and from 2.7% to 7.9%, respectively. As compared with the results of NACDG standard series and EBS, KSS lacked fragrance and cosmetic series of allergens, especially fragrance mix II, methyldibromoglutaronitrile, and methylisothiazolinone, and epoxy series of allergens. Conclusion: Our results, especially the increasing trends of balsam of Peru and paraben mix, would be further confirmed in a multicenter study. Additionally, in view of the increase in fragrance and preservative allergens, KSS would need the addition of related allergens. (Korean J Dermatol 2020;58(6):371∼381)

어머니의 양육신념과 애착이 초등학생 자녀의 자기조절을 통해 자기관리기술에 미치는 영향

The main aim of the current study is to examine the effects of mothers` parental beliefs and mother-child attachment on school-aged children`s time management and life management skills through the mediation effects of children`s self-regulation. Study participants included a total of 317 fifth- and sixth-grade children at elementary schools located in Seoul and Gyeong-gi area, and their 317 mothers. Children and mothers completed questionnaires and Structural Equation Modeling was adapted as the main analysis technique. The findings were the following: First, mothers` parental beliefs that emphasize the child`s independence were significantly related to greater self-regulation ability in children, indicated by cognitive, motivational, and behavior regulation. Second, better quality of mother-child attachment perceived by children was also found to predict greater self-regulation in children. Third, children`s self-regulation was strongly related to time and life management skills. When the child is better at self control, the child showed greater management skills, both in time and everyday life. Finally, as hypnotized, the test yielded a significant mediation effect of self-regulation in the association from mothers` parental beliefs and mother-child attachment to children`s time and life management skills. The findings suggested the important role of parental beliefs about child rearing and attachment between mother and child in developing self-regulation and management skills of school-aged children.

The purpose of this study is to understand the daily lives of adolescents during the COVID-19 pandemic and to provide educational implications for enhancing the competencies of adolescents living in rapidly-changing environments. To this end, the photovoice method, consisting of orientation, documentation, discussion, and analysis, was employed to study nine adolescent participants, who were interested in sharing aspects of their daily lives. The results yielded four themes and nine sub-themes. The first theme is “home life”, which is composed of two sub-themes: most comfortable to be alone and EA (eating alone) for lunch. The second theme is “leisure life”, which consists of two sub-themes: the virtual world of playing with friends and exercise is the only way out to breathe. The third theme is “school life”, which consists of three sub-themes: time for inner exploration and reflection, cracks in daily life due to excessive autonomy, and pros and cons of virtual classes. The fourth theme is “the voice of adolescents”, which consists of two sub-themes: requiring adults to set a golden example and anxious voices due to an uncertain future. This photovoice method of study is meaningful in that it explores the daily lives of adolescents during the COVID-19 pandemic and provides valuable educational implications.
