There has been an exponential increase in plastic surgery cases over the last 20 years, surging from 2.8 million to 17.5 million cases per year. Seventy-two percent of these cases are being performed in the office-based or ambulatory setting. There are certain advantages to performing aesthetic procedures in the office, but several widely publicized fatalities and malpractice claims has put the spotlight on patient safety and the lack of uniform regulation of office-based practices. While 33 states currently have legislation for office-based surgery and anesthesia, 17 states have no mandate to report patient deaths or adverse outcomes. The literature on office-base surgery and anesthesia has demonstrated significant improvements in patient safety over the last 20 years. In the following review of the proceedings from the PRS Korea 2018 meeting, we discuss several key concepts regarding safe anesthesia for office-based cosmetic surgery. These include the safe delivery of oxygen, appropriate local anesthetic usage and the avoidance of local anesthetic toxicity, the implementation of Enhanced Recovery after Surgery protocols, multimodal analgesic techniques with less reliance on narcotic pain medications, the use of surgical safety checklists, and incorporating "the patient" into the surgical decision-making process through decision aids.

Objectives : This study was aimed to investigate stress and coping strategy in the families of schizophrenic patient, and changes of knowledge, stress and coping strategy after brief program of family education compared with control group Methods : The education group consisted of twenty four people who were families with schizophrenic patients and attended the brief program of family education. The control group consisted of twenty two people with schizophrenic inpatients. Self-report questionnaires such as Family Coping Questionnaire(FCQ), Patient Rejection Scale(PRS), Worry Questionnaire, Knowledge Questionnaire, Beck Depression Inventory(BDI), and State-Trait Anxiety Inventory(STAI) were administered to the education group and the control group, twice at the pre-test and post-test. Results : 1) In the education group, scores of worry questionnaire, BDI and STAI-S at the post-test were significantly lower than those at the pre-test. Social interests score of FCQ and knowledge questionnaire score at the post-test were significantly higher than those at the pre-test. In FCQ factors, social interests associated with avoidance strategy score at the post-test was significantly higher than that at the pre-test. However, in the control group, there was no significant difference in all questionnaires. 2) In the education group, significant positive correlation existed between calculated differences of worry questionnaire and STAI-S, and between worry questionnaire and STAI-T, whereas significant negative correlation existed between positive communication of FCQ and PRS, and between knowledge questionnaire and STAI-S. In the control group, significant negative correlation existed between information of FCQ and PRS, and between positive communication of FCQ and PRS. 3) In the education group, significant positive correlation existed between calculated differences of worry questionnaire and age of patient, whereas significant negative correlation existed between knowledge questionnaire and duration of illness. However, in the control group, there was no significant correlation. Conclusion : The brief program of family education was effective in increasing knowledge about schizophrenia, decreasing worry and anxiety about the patients in families with schizophrenic patient. In the education group as knowledge about schizophrenia increased, anxiety about schizophrenic patient decreased, but there was no significant correlation in the control group. As relative's rejection feeling about schizophrenic patient decreased, positive communication strategy increased in both groups. However, the control group was more affected by rejection feeling than the education group.

The research was conducted to find optimal habitats of warm-temperate evergreen broad-leaved trees, and to investigate climate factors to determine their distribution using classification tree (CT) analysis. The warm-temperate evergreen broad-leaved trees model (EG-model) constructed by CT analysis showed that Mean minimum temperature of the coldest month (TMC) is a major climate factor in determining distribution of warm-temperate evergreen broad-leaved trees. The areas above the $-5.95^{\circ}C$ of TMC revealed the optimal habitats of the trees. The coldest month mean temperature (CMT) equitable to $-5.95^{\circ}C$ of TMC is $-1.7^{\circ}C$, which is lower than $-1^{\circ}C$ of CMT of warm-temperate evergreen broad-leaved trees. Suitable habitats were defined for warm-temperate evergreen broad-leaved trees in Korea. These habitats were classified into two areas according to the value of TMC. One area with more than$-5.95^{\circ}C$ of TMC was favorable to trees if the summer precipitation (PRS) is above 826.5mm; the other one with less than $-5.95^{\circ}C$ of TMC was favorable if PRS is above 1219mm. These favorable conditions of habitats were similar to those of warm-temperate evergreen broad-leaved trees in Japan. We figured out from these results that distribution of warm-temperate evergreen broad-leaved trees were expanded to inland areas of southern parts of Korean peninsula, and ares with the higher latitude. Finally, the northern limits of warm-temperate evergreen broad-leaved trees might be adjusted accordingly.

Background: Pathological factors, based mainly on immunohistochemistry (IHC) and histological differentiation, are mostly used to differentiate breast cancer (BC) subtypes. Our present aim was to describe the characteristics and survival of a relapsing BC patient cohort based on clinico-pathologic subtypes determined for the primary tumors. Methods: We used a clinico- pathological definition of BC subtypes based on histological grade (HG), estrogen receptor (ER), progesterone receptor (PgR),and epidermal growth factor receptor type 2 (HER2) expression assessed by IHC. We determined variables associated with loco-regional recurrence (LRR), second primaries (SP), systemic recurrence (SR) and post-recurrence survival (PRS). Results: Out of 1,702 patients, 240 (14%) had an event defined as recurrence. Those with recurrent disease were significantly younger than those without,and were initially diagnosed at more advanced stages, with larger tumors, greater lymph nodal involvement and higher HG. With a median follow up of 61 months (1-250), 4.6% of patients without recurrence and 56.6% of patients with an event defined as recurrence had died. The median PRS for the LRR group was 77 months; 75 months for those who developed a SP and 22 months for patients with an SR (p <0.0001). In SR cases, the median PRS was shorter for ER- tumors than for ER+ tumors (15 vs. 26 months, respectively; p = 0.0019, HR 0.44; CI: 0.25-0.44). Conclusions: Subtype, defined through classic histopathologic parameters determined for primary tumors, was found to eb related to type of recurrence and also to prognosis after relapse.

Objective: This study aimed to investigate the regional amyloid burden and myocardial deformation using T1 mapping and strain values in patients with cardiac amyloidosis (CA) according to late gadolinium enhancement (LGE) patterns. Materials and Methods: Forty patients with CA were divided into 2 groups per LGE pattern, and 15 healthy subjects were enrolled. Global and regional native T1 and T2 mapping, extracellular volume (ECV), and cardiac magnetic resonance (CMR)-feature tracking strain values were compared in an intergroup and interregional manner. Results: Of the patients with CA, 32 had diffuse global LGE (group 2), and 8 had focal patchy or no LGE (group 1). Global native T1, T2, and ECV were significantly higher in groups 1 and 2 than in the control group (native T1: 1384.4 ms vs. 1466.8 ms vs. 1230.5 ms; T2: 53.8 ms vs. 54.2 ms vs. 48.9 ms; and ECV: 36.9% vs. 51.4% vs. 26.0%, respectively; all, p < 0.001). Basal ECV (53.7%) was significantly higher than the mid and apical ECVs (50.1% and 50.0%, respectively; p < 0.001) in group 2. Basal and mid peak radial strains (PRSs) and peak circumferential strains (PCSs) were significantly lower than the apical PRS and PCS, respectively (PRS, 15.6% vs. 16.7% vs. 26.9%; and PCS, -9.7% vs. -10.9% vs. -15.0%; all, p < 0.001). Basal ECV and basal strain (2-dimensional PRS) in group 2 showed a significant negative correlation (r = -0.623, p < 0.001). Group 1 showed no regional ECV differences (basal, 37.0%; mid, 35.9%; and apical, 38.3%; p = 0.184). Conclusion: Quantitative T1 mapping parameters such as native T1 and ECV may help diagnose early CA. ECV, in particular, can reflect regional differences in the amyloid deposition in patients with advanced CA, and increased basal ECV is related to decreased basal strain. Therefore, quantitative CMR parameters may help diagnose CA and determine its severity in patients with or without LGE.

This study was performed to investigate the emotional state related to dental fear, hospital anxiety and depresison, and frequency of stress symproms of orofacial region. For this study, Dnetal Fear Surfey(DFS) scale, the Hospital ANxiety and Depression(HAD) scale, and Stress Symptom Questionnaire(SSQ) designed by the author were used in 549 dental outpatients. Dental Fear Survey scale is composed of avoidance of dentistry(AVOI), physiologic response scale(PRS) and dental stimulus response scale(DSRS). The Hospital anxiety and Depresiosn scale is composed of hospital anxiety(HA) and hospital depressoin (HD). Data were analyzed statistically with SPSS program and the results were as follows : 1. The item of the highest positive response rate in DFS scale was 'feeling drill'(82.0%), and in the HAD scale was ' feel as if I am slowed down'(84.1%). 2. Mean score of AVOI, PRS, DSRS and HD were higher in the older group(>25yr) than the yoiunger group(<25yr) and female patients showed higher score of DSRS, HA than male patients. 3. Mean number of items of stress symptoms in extraoral region were 3.4, and in intraoral region, were 4.7. Tongue wymptoms were increased in the older toup and female patients had more stress symptoms than male patients. 4. Correlation between DFS scale and HAD scale were significantly positive and these scales were also apositively correlated with tongue symptoms. 5. As for treatment types, the patients treated in the department of periodontics,conservative dentistry, and oral surgery showed higher score of DFS scale than the patients with temporomandibular disorders or treatedin the department of orthodontics.

The purpose of the research is to evaluate the current online PR activities focused on the websites of university archives. To achieve the goal, the research developed the indicators to assess online PR activities by synthesizing both the factors derived from the basic components and concepts of PRs at university archives and the existing indexes for evaluating the online PRs of related cultural organizations such as libraries, museums, archives, and non-profit organizations. The research found that most university archives did not have promotional activities positively because there was lack of archival information services development. Even if there were some archival information services, they were not actively publicizing the facts. On the basis of the results, the research suggested the alternatives to improve online PR activities and follow-up research topics to supplement limitations of the research.

The purpose of this study is to investigate service factors and relationships affecting customer satisfaction by measuring indexes of the entire set of high-speed railway station facilities and train services. In this study, we collected data from 202 KTX passengers and analyzed the data using the structural equation model (SEM) method. Through exploratory factor analysis (EFA), we found five major service factors, including parking related service (PRS), station convenient facilities related service (SCS), ticketing services (TIS), service within the train (SWT), and inner environments (INE). As result of a hypothesis test, it was found that PRS does not influence SWT, whereas SCS and TIS positively affect train related service. Also, SWT and INE significantly affect the overall service satisfaction of customers. Thus, our findings provide that station facilities and train service experience are important factors that can enhance customer satisfaction.

As companies seek lower cost and superior quality at the same time, which depend on improvement in product architecture, they need to critically consider product architecture as part of corporate strategy. This research investigated how product architecture and organizational capability affect innovative outcomes with using architecture framework. As a result, we were able to find out Korean shipbuilding company has put much effort on integral works such as development of FGSS(Fuel gas supply system), PRS(Partial Re-liquefaction System) and weight lightening for improving fuel efficiency. And this kind of integral ability was realized by organizational capability of Korean shipbuilding company based on interactive relationship with plant workers. In contrast, Chinese shipbuilding companies focused excessively on the standard design and the convenience of research and development made by central government, overlooking the need for fine-tuning. As a result, the fuel efficiency of Chinese LNG ships turned out to be 7-10% lower than those of South Korea with using the same modules and components.
