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.

Background and Objectives:Brief psychosis is not a sharply demarcated and little is known its nosological entity. Previous studies indicate that 30% to 60% of patients with acute transient psychotic disorder (ATPD) are rediagnosed with bipolar disorder or schizophrenia but there is no way to expect who will be re-diagnosed as other disorder. The aim of this study was to evaluate the diagnostic stability of DSM-IV-TR recurrent brief psychotic disorder (BPD) retrospectively. Method:We investigated 30 patients who had a first-ever admission as DSM-IVTR BPD and were re-admitted at least once to the psychiatric ward of the Asan Medical Center from 1989 to 2009. An analysis of re-admission pattern of all subjects was conducted. Results:Only 10 cases retain their diagnosis on subsequent admission and diagnostic stability is 33.3%. The rest, 20 cases are re-diagnosed at the last;11 for bipovlar disorder, 4 for schizophrenia, 4 for schizoaffective disorder and 1 for schizophreniform disorder. No significant demographic, social or clinical predictors were found. Conclusion:The findings imply the need for validation of the concept of BPD. We suggest that BPD have some similarities with bipolar spectrum disorder.

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.

Objective : The purpose of this study is to summarize the differential diagnosis between allergic and nonallergic rhinitis and suggest management. Methods : We reviewed the current update of medical history and physical examination for allergic and nonallergic rhinitis. Then we analyzed clinical characteristics according to onset age, gender incidence and state of nasal symptoms, etc. Results : 1. Patients with nonallergic rhinitis tend to develop symptoms at a later age(>35 years of age), and there is a female-to-male incidence ratio for nonallergic rhinitis of 2:1 to 3:1. 2. Patients with nonallergic rhinitis report nasal congestion, nasal rhinorrhea and more often report postnasal drip rather than sneezing and itching, which are predominant symptoms of allergic rhinitis. And the nasal mucosa in nonallergic rhinitis usually looks normal. 3. Patients with nonallergic rhinitis have few complaints of concomitant symptoms of allergic symptoms and the absence of other atopic diseases in the patient or in the family supports the diagnosis of nonallergic rhinitis. 4. Common triggers of nonallergic rhinitis are nonspecific irritant exposures and many patients with nonallergic rhinitis find that antihistamines have no benefit. Conclusions : The differential diagnosis between allergic and nonallergic rhinitis is clinical and relies on a detailed medical history and physical examination.

Islet Cell Tumors of the Pancreas: A Variety of Multiphase Dynamic Imaging Findings with Pathologic Correlations Focusing on Nonfunctioning Tumors and Insulinomas

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.

반복 진술 시 나타나는 진술의 정확성 및 진술 간 일관성에 관한 연구 - 범죄사건 진술의 진위여부에 따른 차이를 중심으로 -

홍유진,김시업 원광대학교 경찰학연구소 2017 경찰학논총 Vol.12 No.4

본 연구에서는 수사적 맥락에서 반복적으로 진술할 때 나타나는 진술의 정확성과 반복 진술 간 일관성에 대해 살펴보고자 하였다. 시간의 경과 후 진술이 반복되었을 때 진실한 화자와 거짓 화자의 진술이 어떻게 나타나는지 살펴보기 위해 대학생 총 60명을 대상으로 실험을 실시하였다. 참가자들은 범죄 영상을 시청하고 이에 대해 진실하게 혹은 거짓으로 진술한 후 1주일 경과 후 다시 진술하였다. 이들의 진술서를 대상으로 이전 진술과 나중 진술 간의 차이를 진술의 진위여부에 따라 분석하였다. 그 결과, 진실한 화자와 거짓 화자 모두 두 진술 간 보고한 전체 정보량에는 차이가 없었다. 하지만, 진실한 화자는 정확한 정보는 감소하고 오정보가 증가하였고, 거짓 화자는 거짓 정보가 증가하였다. 이전 진술과 나중 진술 간 일관성은 진실한 화자가 거짓 화자보다 더 높게 나타났다. 진실한 화자와 거짓 화자 모두 유지된 정보와 삭제된 정보에서는 정확한 정보의 양이 가장 많았고, 추가된 정보에서는 진실한 화자는 정확한 정보가, 거짓 화자는 거짓 정보가 더 많았다. 이러한 결과를 바탕으로 진술의 양과 질을 향상시키기 위한 방안을 모색하고 진술의 진위 여부에 따른 반복 진술의 특성에 대한 후속 연구의 방향에 대하여 제언하고자 하였다. In this study, we researched the accuracy and consistency of repeated statement in investigation contexts. To accomplish these purposes, we look into the statement of tellers who tell the truth or false as time passed and the subject of research are 60 students. The participants watched the videos about crimes in first-person. All participants had stated the case as true or false and stated again after one weeks later. We analyzed the differences of previous and subsequent statement. Also, we compared memory process between the honest and deceptive statement. As a result, No differences between previous reported amount and subsequence reported amount. This result revealed both truth tellers and liars. Compared with the previous, Truth tellers more reported false information and less reported correct information in subsequence interview. liars more reported deception in subsequence statement than previous statement. And, on the consistency between statements, True teller has more higher than liars. Also, the amount of information about maintain and deletion, correct information is the highest. But the about additional information, can be seen more correct information in truth tellers but more deceptive information in liars. Therefore, based on these result, find ways for improvements of quantity and quality of statement and this findings provides insight and understanding for future direction of research about repeated statement.

Serum Elastin-Derived Peptides and Anti-Elastin Antibody in Patients with Systemic Sclerosis

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.

청소년의 죄책감에 영향을 미치는 요인 - 귀인성향과 또래동조성을 중심으로 -

홍유진,김시업 아시아교정포럼 2015 교정담론 Vol.9 No.3

본 연구에서는 범죄 예방적 측면에서 죄책감을 논의하기 위해 이론적 고찰과 실증적 연구를 수행하였다. 먼저, 청소년들의 죄책감에 영향을 미치는 요인을 살펴보 위해 우선 선행연구를 중심으로 죄책감의 개념을 정리하고, 청소년들의 죄책감에 영향을 미치는 요인을 살펴보았다. 이를 위해 도덕적 정서와 관련지어 죄책감의 개념을 살펴보고, 죄책감과 비교할 수 있는 개념인 수치심과의 차이점을 살펴보았다. 선행연구를 토대로 죄책감에 영향을 미치는 주요 요인을 살펴본 결과, 개인적 요인으로는 연령, 성별, 비행경험(범죄경험)이, 대인적 요인으로는 가정환경적 요인으로 부모의 훈육방식이 죄책감에 영향을 미치는 것으로 나타났다. 선행연구를 통해 밝혀진 요인 이외에, 귀인성향이 정서 수행에 영향을 미친다는 Weiner(1986)의 이론을 바탕으로 죄책감도 정서의 한 종류라는 점과, 또래동조성이 청소년들의 반사회적 행동에 영향을 미친다는 선행연구들을 토대로 죄책감은 반사회적 행동 시 유발된다는 점에 주목하여 귀인성향과 또래동조성이 청소년의 죄책감에 어떠한 영향을 미치는지 알아보고자 하였다. 이를 위해 경상도 소재의 남녀 중・고등학생 90명을 대상으로 귀인성향, 또래동조성, 죄책감, 잠재적 비행성향에 대한 설문을 실시하였다. 그 결과, 내부귀인 점수가 낮을수록 죄책감이 낮았다. 또, 반사회적 상황에서 또래 동조성이 높을수록 죄책감이 낮게 나타났다. 뿐만 아니라, 죄책감 고저에 따른 잠재적 비행성향을 살펴본 결과, 죄책감이 낮은 집단이 죄책감이 높은 집단에 비해 잠재적 비행성향이 높은 것으로 나타났다. 내적 귀인성향과 반사회적 행동에 대한 또래동조성이 죄책감에 영향을 미친다는 이러한 결과를 토대로 청소년의 행동에 긍정적인 영향을 미치고 더 나아가 궁극적으로는 청소년 범죄를 감소시킬 수 있는 죄책감의 정적 기능에 초점을 둔 인성 함양 방안에 대해 논의 하고자 하였다. The current study examined the concept of guilty feeling in regard to moral emotion, and compared it to a similar concept of shame. Previous studies found that individual factors(age, gender and delinquency or experience of crimes) and family environmental factors (parenting and discipline styles) could affect formation of guilty feeling. Also Weiner (1986) pointed out that antisocial behaviors in adolescence could be influenced by peer conformity. The current study also looked into the effects of attribution tendencies and peer conformity on guilty feeling in adolescents. The data were collected from 90 middle and high school students. The results showed that the lower the level of internal attribution was related to lower level of guilty feeling. Also, in antisocial situations, higher level of peer conformity was related to lower level of guilty. Finally, we can consider ways to forester adolescents' guilty feeling that decrease juvenile delinquency through these results.
