A novel bacterium, designated strain RR4-56T, was isolated from a biofilter of a seawater recirculating aquaculture system. The 16S rRNA gene sequence analysis showed that the isolate was closely related to Halovulum dunhuangense YYQ- 30T (92.6%), Albimonas donghaensis DS2T (91.3%), Pontivivens insulae GYSW-23T (91.3%), and Monaibacterium marinum C7T (90.9%), belonging to the family Rhodobacteraceae. The strain was aerobic, Gram-negative, rod-shaped, oxidasepositive, and catalase-negative. Its optimum temperature, pH, and salinity for growth were 25–30°C, pH 8.5, and 2–3% NaCl (w/v), respectively. Its growth occurred at 15–35°C, pH 5.0–9.5, and 0–7% NaCl (w/v). It contained ubiquinone-10 (Q-10), a respiratory quinone, and the major cellular fatty acids were 11-methyl C18:1 ω7c (31.9%), C18:1 ω6c (30.4%), and C19:0 cyclo ω8c (16.1%). The polar lipids present in the strain were phosphatidylglycerol, an unidentified phospholipid, and an unidentified aminolipid. The strain had one 4,373,045 bp circular chromosome with G + C contents of 65.9 mol% including 4,169 genes, 4,118 coding sequences (CDSs), 3 rRNAs, and 45 tRNAs. Genome annotation predicted some gene clusters related to the degradation of several types of organic matter such as protocatechuate, catechol, and phthalate. Based on the polyphasic characteristics, RR4-56T represents a novel genus and species in the family Rhodobacteraceae, for which the name Pikeienuella piscinae gen. nov., sp. nov. was proposed. The type strain is RR4-56T (= KCTC 52648T = DSM 107918T).

JoonHyung Jung,MinJoo Kim,SooHee Choi,NaYoung Han,JeeEun Park,HyeYoun Park,JiWon Han,DongYoung Lee,HyeYoon Park 대한신경정신의학회 2017 PSYCHIATRY INVESTIGATION Vol.14 No.6

Objective-In this study, we aimed to investigate preferences regarding the disclosure of a dementia diagnosis and advance care planning (ACP) in patients with memory complaints and their families. Methods-A total of 98 patients who visited the department of psychiatry at a tertiary hospital with memory complaints and 62 family members completed a structured questionnaire. The questionnaire included preferences on disclosure of dementia and cancer diagnosis, awareness and preferences on ACP. Results-In total, 96.9% of patients were willing to know their dementia diagnosis. There were no significant differences in preferences between the diagnosis of cancer and dementia. Only 24.7% of patients and 45.8% of family members have heard of ACP. However, 82.8% of patients agreed on the necessity of ACP under the current condition. Multivariate analysis revealed that younger patients were more likely to agree with necessity for ACP under the current condition. Conclusion-In Korea, patients with memory complaints and their family members strongly favored a disclosure of dementia diagnosis. The majority of participants also agreed on the necessity of ACP. More active involvement of patients is needed in treatment decisions and care planning in cases of dementia as well as other life-threatening illnesses.

감각의 확장을 통한 디자인교육의 가능성 연구

박영진(Park, Young Jin),이지은(E, Jeeeun),김효일(Kimm, Hyoil) 한국디지털디자인협의회 2015 디지털디자인학연구 Vol.15 No.1

사회문화와 경제를 기반으로 디자인이라는 문제해결을 위한 적극적인 개입방법은 다른 이보다 독창적인 문제해결의 대안을 제시하는 편이 디자인의 능력을 인정받는 시대이다. 디자인을 거시적인 안목과 미시적인 안목으로 볼 때 합목적성과 심미성이라는 틀거리에서 창조적인 활동의 영역으로 범주화시키기 위해 시각과 청각, 후각, 미각, 촉각의 오감을 활용한 공감각적 감각에 의한 창의성을 증대시킬 수 있을 것이다. 디자인교육은 창의적인 활동을 추구하는 영역이므로 다양한 감각을 활용하여 보다 적극적인 결과물을 양산해야 하는 분야이다. 이러한 이유로 디자인의 창의적 결과물을 위해 인간의 지각능력을 극대화하고, 여기에서 발생되는 창의적 결과물에 대한 교육이 필요한 것이다. 디자인교육 과정은 디자인의 최종 목적인 창의적인 결과물을 지향하게 되므로 디자인교육의 기초적인 영역과 실무적인 영역으로 구분하고 창의성을 극대화하기 위한 과정은 기초디자인교육과정에서 이루어져야 할 것이다. In a society based on the culture and economy of design methods for problem solving is to present an alternative to the creative problem solving than others. In order to categorize the design into the realm of creative activities in the area of finality and aesthetics, can increase your creativity by using the five senses Synesthesia. The design education is an area in pursuit of creative activity, and production areas for which we need to take advantage of the resulting sense. For this reason, in order to maximize the human perception of creative product of design and training for creative results generated here is necessary. Since the design-oriented curriculum in creative output, separated by a basic region and the practical areas of design education, the process to maximize creativity will be made in the basic design courses.

MaengJe Cho,SuJeong Seong,JeeEun Park,InWon Chung,YoungMoon Lee,Ahn Bae,JoonHo Ahn,DongWoo Lee,JaeNam Bae,SeongJin Cho,JongIk Park,Jungwoo Son,SungMan Chang,BongJin Hahm,JunYoung Lee,JeeHoon Sohn,JinS 대한신경정신의학회 2015 PSYCHIATRY INVESTIGATION Vol.12 No.2

Objective-The aim of this study was to estimate the prevalence and correlates of mental disorders in Korean adults. Methods-Door to door household surveys were conducted with community residents aged 18–74 years from July 19, 2011, to November 16, 2011 (n=6,022, response rate 78.7%). The sample was drawn from 12 catchment areas using a multistage cluster method. Each subject was assessed using the Korean version of the World Health Organization Composite International Diagnostic Interview (CIDI) based on the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV). Results-Lifetime and 12-month prevalence estimates were as follows: alcohol use disorders, 13.4% and 4.4%, respectively; nicotine use disorders, 7.2% and 4.0%, respectively; anxiety disorders, 8.7% and 6.8%, respectively; and mood disorders, 7.5% and 3.6%, respectively. The prevalence rates of all types of DSM-IV mental disorders were 27.6% and 16.0%, respectively. Being female; young; divorced, separated, or widowed; and in a low-income group were associated with mood and anxiety disorders after adjustment for various demographic variables, whereas being male and young were associated with alcohol use disorders. Higher income was not correlated with alcohol use disorder as it had been in the 2001 survey. Conclusion-The rate of depressive disorders has increased since 2001 (the first national survey), whereas that of anxiety disorders has been relatively stable. The prevalence of nicotine and alcohol use disorders has decreased, and the male-to-female ratio of those with this diagnosis has also decreased.

Comparison Study on Photodynamic Anticancer Activity of Multifunctional Magnetic Particles by Formation of Cations

Kyong-Hoon Choi,Eun-Wook Choi,Jeeeun Min,Hyungbin Son,Han Sup Uhm,Eun HaChoi,Bong Joo Park,Jin-Seung Jung IEEE 2014 IEEE transactions on magnetics Vol.50 No.11

<P>In this paper, we have synthesized multifunctional magnetic particles (MNPs) using by two different ferrite submicrometer paticles (Fe<SUB>3</SUB>O<SUB>4</SUB>@HP and CoFe<SUB>2</SUB>O<SUB>4</SUB>@HP) with different surface properties. Two different multifunctional particles have the same particle sizes within the error tolerance of 4.5%. The concentration measurement of the hematoporphyrin (HP) molecule indicates that the weight of HP molecules bonded to the surface of the Fe<SUB>3</SUB>O<SUB>4</SUB> particles is smaller than that of the CoFe<SUB>2</SUB>O<SUB>4</SUB> particles. Moreover, we have evaluated their biocompatibilities and photodynamic anticancer activities on mammalian cells. The two MNPs have demonstrated that they both have good biocompatibilities without any cytotoxicity and anticancer activities in the concentration range of 0-50 μg/mL. Specifically, photodynamic-killing activities of both MNPs were measured to be 100% for CoFe<SUB>2</SUB>O<SUB>4</SUB>@HP, and were measured to be 37.9 ± 3.5% and 9.2 ± 2.5% for Fe<SUB>3</SUB>O<SUB>4</SUB>@HP in 25 and 50 μg/mL of both MNPs. These results suggest that both MNPs can be safely used to for clinical photodynamic cancer therapy, although the CoFe<SUB>2</SUB>O<SUB>4</SUB>@HP showed a slightly better photo-killing efficacy compared with the Fe<SUB>3</SUB>O<SUB>4</SUB>@HP in prostate cancer.</P>

대학생의 사교육 수요에 관한 탐색적 연구

김지하(Ji-Ha Kim),박지은(JeeEun Park) 한국교육재정경제학회 2008 敎育財政 經濟硏究 Vol.17 No.1

본 연구의 목적은 대학생들의 사교육 수요에 영향을 주는 요인들을 실증자료로 분석함으로써 대학생들의 사교육 수요 양상과 그 원인에 대해 규명하여 고등교육관련 정책 수립시 기초자료를 제공하는데 있다. 한국교육고용패널자료(KEEP)를 활용하여 1차년도 고등학생 3학년과 2차년도 대학교 1학년 자료를 분석하였고 주된 연구방법으로는 프로빗과 토빗 회귀모형을 사용하였다. 본 연구의 결과는 다음과 같다. 첫째, 여학생일 경우, 수학능력시험성적과 강의 태도가 좋은 학생일수록 사교육 수요가 높았고 둘째, 학부모의 학력이 높을수록 대학생 자녀의 사교육 수요가 높았다. 셋째, 개인의 미래 학업 및 진로계획에 관한 변수인 편입계획과 해외유학 계획이 있는 학생일수록 사교육 수요가 높은 것으로 나타났다. 또한 고교시절 과외를 받은 경험이 있는 학생일수록 대학진학 후에도 사교육을 받을 확률이 높았고 사교육비도 많이 지출하는 것으로 나타났다. 넷째, 재학생들의 대학생활만족도가 낮은 대학에 소속된 학생일수록 사교육 수요가 높았다. 이상의 결과는 대학생의 사교육 투자행위가 학업성적과 성취동기가 높은 학생들이 학점경쟁 및 취업경쟁에서 비교우위를 가지기 위한 전략으로서 그 목적이 보충교육이 아닌 교육 및 취업경쟁에서 우위를 접하기 위한 행위임을 보여준다. 아울러 평균 대학만족도가 낮은 대학의 재학생일수록 사교육 참여확률이 높다는 점은 대학교육이 수요자의 요구에 보다 적극적으로 반응하며 질적 수월성을 꾀해야 함을 시사한다. The purpose of this study is to estimate the demand for college students" private tutoring(PT). This study uses the Korean Education Employment Panel(KEEP) data to get the estimates of regression models for Limited Dependent Variables. In doing so, the study takes advantage of the marginal effect and standardized coefficients that are generally used to determine absolute and relative effects of each independent variable. The main findings are as follows: First, the college students" demand for PT is affected by individual characteristics such as gender, class attitude, and SAT score. Also college students are more likely to take PT lessons as the parents schooling increases. This results implies that the college students choose PI as a competitive strategy to get a decent job in the labor market. Second, the students" satisfactions with their universities are negatively associated with the demand for PT. From a policy perspective, it is recommended that higher education policy should be focused on the improvement of the quality of education which can meet and support the demand of industry and employers.

청자의 경험, 화자의 조음 중증도, 단서 유형이 인공와우이식 선천성 농 성인의 말명료도에 미치는 영향

이영미(Lee YoungMee),성지은(Sung JeeEun),박정미(Park JeongMi),심현섭(Sim HyunSub) 한국음성학회 2011 말소리와 음성과학 Vol.3 No.1

The current study investigated the effects of experience of deaf speech, severity of speaker’s articulation, and linguistic cues on speech intelligibility of congenitally deafened adults with cochlear implants. Speech intelligibility was judged by 28 experienced listeners and 40 inexperienced listeners using a word transcription task. A three-way (2 × 2 × 4) mixed design was used with the experience of deaf speech (experienced/inexperienced listener) as a between-subject factor, the severity of speaker’s articulation (mild to moderate/moderate to severe), and linguistic cues (no/phonetic/semantic/combined) as within-subject factors. The dependent measure was the number of correctly transcribed words. Results revealed that three main effects were statistically significant. Experienced listeners showed better performance on the transcription than inexperienced listeners, and listeners were better in transcribing speakers who were mild to moderate than moderate to severe. There were significant differences in speech intelligibility among the four different types of cues, showing that the combined cues provided the greatest enhancement of the intelligibility scores (combined > semantic > phonological > no). Three two-way interactions were statistically significant, indicating that the type of cues and severity of speakers differentiated experienced listeners from inexperienced listeners. The current results suggested that the use of a combination of linguistic cues increased the speech intelligibility of congenitally deafened adults with cochlear implants, and the experience of deaf speech was critical especially in evaluating speech intelligibility of severe speakers compared to that of mild speakers.
