In this study, in order to develop a method to efficiently inject essential nutrients necessary for plant growth into wood chips, which are simply used as soil covering materials in the agriculture, landscaping and horticultural industries, the atmospheric pressure dipping method and the vacuum pressure impregnating method are used to improve the plant nutrients injectability and impregnation amount were comparatively analyzed. Nutrient ingredients and 8 major heavy metal contents of wood chips injected with nutrients were analyzed, and soil covering effects were examined by covering wood chips injected with nutrients on soil. Comparing the dipping method and the vacuum pressure impregnation method, it took about 48 hours or more to inject 1,500 g or more of the nutrient aqueous solution into 1 kg of wood chips in the dipping method, but the vacuum pressure impregnation method could be impregnated in about 5 minutes. Components of the impregnated nutrients were detected in proportion to the diluted concentration. As a result of covering the wood chips developed in this study on soil, they showed weakly acidic pH, and the heat insulation and moisturizing effects during the winter season were evaluated to be superior to those of uncovered soil. In the future, wood chips impregnated with nutrients are expected to contribute to the more efficient use of waste wood resources and the long-term supply of nutrients essential for plant growth, reducing excessive use of chemical fertilizers and reducing costs.

홍유진,유정식,박찬일,권지은,정재준,김주희,김기황 대한영상의학회 2010 대한영상의학회지 Vol.63 No.5

Islet cell tumors (ICTs) are rare pancreatic neoplasms of neuroendocrine origin, posing a diagnostic challenge to radiologists. We illustrated a spectrum of features of pancreatic ICTs that could be found on multiphase dynamic CT or MRI, and elucidated the histopathologic characteristics by determining the contrast enhancement pattern of the lesions. Various enhancement patterns were dependant on the internal composition of the tumor, that is, the proportion of vascular densities for early enhancement and non-hypervascular interstitial tissue for late enhancement regardless of the size or functional behavior. This knowledge of the imaging-pathologic spectrum of ICTs could be helpful for the proper differential diagnosis from other pancreatic tumors.

Objective : This case series study was designed to assess the effect of Gamisungmagalguntang for chronic urticaria identified as "Wind-Heat" pattern by retrospective methods. Methods : We treated 19 patients for chronic urticaria with Gamisungmagalguntang(加味升麻葛根湯), who visited to care chronic urticaria at the department of Ophthalmology, Otolaryngology and Dermatology of Korean Medicine at Kyunghee University Korean Medical Center from 1st January 2013 to 31st August 2013. We analyzed information and body conditions of 19 patients. And by using Urticaria Activicy Score(UAS), frequency and number of wheals, itch severity and total score on a 4-point(0-3) scale were assessed in 19 patients. The change of each criterion and total scores between baseline and follow up were analyzed using paired t-test and Wilcoxon test(p<0.05). Results : 1. UAS improvement was statistically significant(p<0.001). Effects of symptom improvement were excellent(31.58%) that means symptom remission and good(42.10%) that means symptom improved over 50%. 2. Heat sensitivity as suspected provocation factor could be a marker for the Wind-Heat pattern urticaria. 3. Among the Wind-Heat pattern urticaria patients, normal digestion(52.63%) and no thirst(78.95%) were higher than abnormal conditions. Whereas about sweat item, abnormal conditions(57.89%) were higher than normal. That means abnormal sweat conditions could be a marker for a defense qi(衛氣) dysfunction of the Wind-Heat pattern urticaria. Conclusions : Our findings suggest that Gamisungmagalguntang could be effective on the Wind-Heat pattern urticaria.

홍유진,김진현,Bo Ram Oh,이윤종,이은영,이은봉,이승효,송영욱 대한의학회 2012 Journal of Korean medical science Vol.27 No.5

The elastin metabolism in systemic sclerosis (SSc) has been known to be abnormal. The authors investigated relationship between the clinical manifestations of systemic sclerosis (SSc) and serum levels of soluble elastin-derived peptide (S-EDP) and anti-elastin antibodies. Serum samples were obtained from 79 patients with SSc and 79 age- and sex-matched healthy controls. Concentrations of serum S-EDP and anti-elastin antibodies were measured by ELISA. The serum concentrations of S-EDP in SSc patients were significantly higher than in healthy controls (median, 144.44 ng/mL vs 79.59 ng/mL, P < 0.001). Serum EDP concentrations were found to be correlated with disease duration in SSc (P = 0.002) and particularly in diffuse cutaneous SSc (P = 0.005). Levels of anti-elastin antibodies were found to be more elevated in SSc patients than in healthy controls (median, 0.222 U vs 0.191 U, P = 0.049), more increased in diffuse cutaneous SSc than limited cutaneous SSc (median, 0.368 U vs 0.204 U, P = 0.031). In addition, levels of antielastin antibodies were also found to be negatively associated with presence of anticentromere antibody (P = 0.023). The S-EDP levels were not found to be correlated with levels of anti-elastin antibodies. The increased S-EDP and anti-elastin antibody levels and association with clinical and laboratory characteristics may reflect the abnormal metabolism in SSc.

파브리병에서의 심장 자기공명영상의 역할

홍유진,김영진 대한영상의학회 2020 대한영상의학회지 Vol.81 No.2

Fabry disease is a rare X-linked metabolic disorder that is characterized by the accumulation of glycosphingolipids in various organs, resulting from the deficiency of alpha-galactosidase A. Cardiac involvement is relatively common; myocardial inflammation, left ventricular hypertrophy, and myocardial fibrosis secondary to abnormal lipid deposition in myocytes are often observed. Hence, the diagnosis of cardiac involvement is crucial for evaluating patient prognosis. Cardiac MRI is the standard technique for measuring the function, volume, and mass of the ventricles. It is also useful for myocardial tissue characterizations. The evaluation of native myocardial T1 values can facilitate early diagnosis of cardiac involvement, while measurements of left ventricular myocardial mass can be used to monitor treatment outcomes, in patients with Fabry disease. Consequently, cardiac MRI can provide useful information for diagnosing, monitoring, and treating patients with Fabry disease. 파브리병(Fabry disease)은 매우 드문 X-연관 유전 대사 질환으로 알파 갈락토시다아제(alpha galactosidase A)의 결핍으로 인하여 다양한 세포 및 기관에 글리코스핑고지질(glycosphingolipid) 의 축적을 초래하는 질환이다. 심장 침범이 비교적 흔하며 비정상적인 지질침착으로 인한 심근 염증, 좌심실 비대 및 심근 섬유증을 일으킨다. 심장 침범은 환자 예후를 결정하는 중요한 요인이므로 이를 진단하는 것은 매우 중요하다. 심장 자기공명영상은 심실의기능, 부피 측정을 위한 표준기법으로 알려져 있으며 심근의 조직 변화를 볼 수 있는 유용한기법이다. 특히 최근 많이 쓰이는 T1 지도화 기법을 통한 심근 조영 전 T1 수치를 이용하여파브리병의 심장 침범을 조기 진단할 수 있으며 자기공명영상을 이용한 심근 질량 측정으로치료 모니터링을 할 수 있다. 심장 자기공명영상은 파브리병 환자에서 다양한 역할을 할 수있을 것으로 생각되며 이에 대해 정리해보고자 한다.

홍유진,홍경완,김현철 한국경영교육학회 2014 경영교육연구 Vol.29 No.1

Korea's casino industry has continuously developed to be a competitive part of the service sector. The casino industry plays a big role in obtaining foreign currency, creating jobs, and attracting foreign visitors. As part of the tourism infrastructure, it is both profitable and appealing to Asian markets compared with other tourism businesses. Casinos are highly dependent on human resources as compared to other service industries, and the attitude and behavior of casino dealers are important to present a good image of the casino because dealers are direct service providers to customers. The purpose of this study is to investigate the relationship between emotional labor and job stress occurring from the job characteristics of casino dealers because, as stated before, human resources play an important role in the Korean casino industry. Documentary and empirical studies were conducted together to achieve the purpose of the research. A total of 200 questionnaires were collected from May 28 to May 31, 2010 from the current casino dealers working in Seven Luck, Paradise and Kangwon Land casinos. There were 166 usable questionnaires, and frequency analysis, factor analysis, reliability analysis, multiple regression analysis were conducted. The authors discuss both the study's implications and future research directions. 모든 산업은 더욱 심화되는 경쟁 속에서 지속적인 발전을 거듭하며 서비스의 경쟁력을 높이기 위해 집중하고 있다. 오늘날 카지노 산업은 고용창출과 외국인 관광객의 유치로 외화획득의 선두 역할을 하는 산업으로 아시아 시장에서 잠재력이 있는 산업으로 관광인프라 구축에도 도움을 주고 있다. 카지노 산업은 타 서비스 산업에 비해서 인적 자원에 대한 의존 비율이 높아, 이를 전략적으로 활용하는 접근이 한국 카지노 산업에서 중요한 역할을 수행할 것으로 기대되어, 카지노 딜러의 직무스트레와 감정노동의 영향 관계를 살펴보고자한다. 본 연구 목적을 달성하기 위하여 문헌연구와 실증적 연구를 병행하여 실시하며, 2010년 5월 28일부터 31일까지 국내 세븐럭 카지노, 파라다이스카지노, 강원랜드에서 근무하는 딜러 200명의 유효 설문지를 수집하여 불성실한 응답자를 제외한 166부의 표본만을 최종적으로 분류하여 빈도분석, 요인분석, 다중회귀분석 등을 사용하여 결과를 분석·도출하였다.

홍유진,김시업 아시아교정포럼 2017 교정담론 Vol.11 No.1

본 연구는 목격자 진술이 수사 현장에서 가지는 중요성을 살펴보고, 범죄 현장이라는 부적 자극에 의해 발생한 불안이 남성과 여성 목격자 진술에 미치는 영향을 살펴보고자 하였다. 이를 위해 남녀 대학생 총 125명을 대상으로 범죄 사건에 대한 영상을 시청하도록 한 후, 시청한 영상의 내용을 서면으로 작성하도록 하였다. 범죄 영상 시청 전·후의 참가자들의 불안감 수준에 따라 상·하 집단으로 분류하여 각 집단 간 진술의 양과 정확성에 차이가 있는지 분석한 결과, 범죄 장면 목격으로 인해 발생된 불안감 수준이 적게 상승된 집단이 많이 상승된 집단에 비해, 여성이 남성에 비해 진술의 전체 정보량과 정확한 정보량을 더 많이 보고하는 것으로 나타났다. 또한, 여성목격자가 남성목격자에 비해 불안에 부정적인 영향을 더 많이 받는 것으로 나타났다. 이러한 결과를 통해 목격자 진술의 효율성과 추후 연구의 방향에 대해 논의하고자 하였다. The current study examined the significance of eyewitness statement in forensic field. And we aims to investigate the effect of anxiety(caused by the negative stimuli of the crime scene) on the statement of male and female eyewitness. 125 college students were shown the video clip of crime, and then asked them to make a statement in writing. Subjects were divided into two groups according to the degree of heightened anxiety by observing crime scene. Major results are as follow: First, low-level anxiety group reported more informations than high-level anxiety group. and correct information in low-level anxiety group were more in high-level anxiety group. Second, female eyewitness reported more informations than male eyewitness. The negative effects of anxiety on the statement were more female witness than male witness. We can consider way to enhance the efficiency of eyewitness statement and we suggested the future research through these results.
