노동우,백은아,강수균 한국음성과학회 2003 음성과학 Vol.10 No.4

The purposes of this study are; to investigate the swallowing mechanism of stroke patients with different consistencies through the modified barium swallowina:(MBS): and to establish preliminary data on the differences in swallowing durations. 4 different kinds of consistency-water, nectar, pudding, and crackers-were given to 6 stroke patients and their swallowing durations recorded through the fluoroscopy were measured in 1/100 second units. The results show that first swallowing time(FST), the oral preparatory duration(OPD), and the pharyngeal response duration(PRD) were delayed in swallowing thicker consistencies. However, water exhibited delayed oral and pharyngeal phase relative to its consistency and 50% of subjects showed oral loss of water. The relationship between consistencies and swallowing durations and the clinical issues on the stroke population were discussed.

연구목적 : 강박증의 동반인격장애에 관한 연구들은 기존의 개념과 달리 강박성 인격장애와 강박증 간에는 특이적인 관계가 없으며, 강박증 환자들은 다양한 인격장애를 동반한다는 결과를 보여주었다. 그러나 이러한 연구들은 동반 인격장애에 관한 기술적인 분석에 그쳤고, 강박증 환자군의 임상 증상과 동반 인격장애 양상간의 연관성에 관한 분석을 시행하지 않았다. 본 연구의 목적은 강박증 환자군에서의 동반 인격장애를 평가하고 강박증 환자의 다양한 증상과 동반 인격특성 간의 연관성에 대해 연구하는 것이다. 방 법 : DSM-IV의 강박증의 진단기준을 만족하는 59명의 환자군과 32명의 정상대조군을 대상으로 인격장애 질문지를 적용한 후 4∼6점의 절단점을 기준으로 인격장애의 진단이 내려졌다. 먼저 환자군과 정상대조군 간의 특정 인격장애 빈도의 차이를 알아보기 위하여 Fisher's exact test를 시행한 후, 두집단 간에 유의한 차이가 있는 것으로 밝혀진 인격장애 척도 점수에 미치는 Y-BOCS,BDI,BAI점수의 영향을 알아보기 위하여 다중선형회귀 분석을 시행하였다. 결 과 : 1) Fisher's exact test 결과 강박증 환자군은 정상 대조군에 비해 경계성 인격장애(18.6%vs 0%, p=0.007). 회피성 인격장애(55.9% vs 18.8%, p=0.001), 우울성 인격장애(40.7% vs 0%, p=0.000)의 비율이 유의하게 높았다. 2) 다중선형회귀분석 결과 Y-BOCS 점수 (t=2.10, p=0.043)와 BAI점수(t=2.60, p=0.014)는 경계성 인격장애 점수에 유의한 영향을 주는 것으로 나타났다. 또한 BAI점수(t=3.23, p<0.003)는 회피성 인격장애 저수에, BDI점수 (t=3.08, p=0.004)는 우울성 인격장애 점수에 유의한 영향을 주는 것으로 나타났다. 결 론 : 강박증 환자군은 정상 대조군에 비해 회피성 인격장애, 우울성 인격장애, 경계성 인격장애의 동반율이 높고, 강박증이 경계성 인격장애의 심각도에 유의한 영향을 미치는 것으로 사료된다. The purpose of this study was to assess the comorbid axis-Ⅱ disorders of obsessive compulsive disorder(OCD) patients and to investigate the relationship between symptoms of OCD and the comorbid personality traits. The subjects were 59 patients who met DSM-IV criteria for obsessive-compulsive disorder and 32 normal controls. All subjects completed personality Disorder Questionnaire-IV(PDQ-IV). The patients completed Beck Depression Inventory(BDI) and Beck Anxiety Inventory(BAI), and were rated with Yale-Brown Obsessive Compulsive Scale(YBOCS). The results were as follows. 1) The OCD patients showed significantly higher prevalence of avoidant, depresssive and borderline personality disorder(p<0.01) compared to controls. 2) The BAI score had significant effect on the avoidant personality score(t=3,23, p<0.003). The BDI score had significant effect on the depressive personality score(t=3.08, p=0.004). The YBOCS(t=2.10, p=0.043) and BAI(t=2.60, p=0.014) scores had significant effects on the borderline personality score. We found that OCD patients had higher prevalence of avoidant, depressive, and borderline personality disorders. We also found that obsessive-compulsive symptoms have significant effect on the severity of borderline personalty traits. We suggest that it would be very helpful to consider Axis-Ⅱ disorders for managing patients with obsessive-compulsive disorder.

안덕균,김준범,최은정,강동구,최재구 건국대학교 의과학연구소 1993 건국의과학학술지 Vol.3 No.-

본 건국대학교 의과대학 성형외과학 교실에서 Romberg씨 질병으로 좌측의 안면 함몰을 주소로 내원한 여자 환자 1례에서 탈상피화시킨 서혜부 유리 피판술을 시행하여 좋은 결과를 얻었기에 이에 문헌 고찰과 함께 보고하는 바이다. Romberg's disease is progressive hemifacial atrophy, which begins before the age of 20-years, affecting the subcutaneous tissue and skin with later involvement of the muscle and osteocartilagenous frame work. The disease may be heralded by pigmentary changes of the hair, skin, or iris. When present, atrophy may originate from the cutaneous stigmata and may become so sharply delimited by the midline. There are a number of methods to correct the soft tissue deformity of the face. We had experienced 22-year old female patient who had a moderate soft tissue atrophy on the left side of the face. The patient was treated with a de-epithelized groin free flap. Superficial circumflex iliac vessels were used as donor pedicle and the superficial temporal vessels were recipient vessel. Initially moderate bulkiness was noted but after 6 months follow-up period the external contour was good and the patient satisfied. A case presentation and review of literatures are the basis of this report.

활성탄을 이용한 낙동강 상수원수의 수처리 효과

임영성,강관호,이홍재,서동철,허종수,손보균,조주식 한국환경농학회 2002 한국환경농학회지 Vol.21 No.3

상수원수를 보다 효과적으로 처리함으로서 양질의 수돗물을 공급하기 위한 기초자료를 얻고자 낙동강 상수원수를 대상으로 활성탄처리에 의한 공탐체류시간 및 활성탄 여층 깊이에 따른 수처리 효율과 생물활성탄으로서의 이용 가능성을 조사한 결과는 다음과 같다. 공탑체류시간(EBCT)에 따른 수처리 효율은 EBCT가 증가할수록 증가되었으나 운전시간이 경과함에 따라 활성탄 흡착능력은 감소되어 처리효율도 서서히 감소하였다. 활성탄 여층깊이에 따른 pH 변화는 활성탄 층 깊이에 따라 거의 없었으며, D0는 활성탄 층 깊이가 깊을수록 서서히 감소하였다. KMnO^4 소비량, UV254 흡광물질 DOC 및 THMFP 처리효율은 활성만 표층으로부터 하부로 내려갈수록 증가하였으며, 운전시간이 경과할수록 활성탄 상층부에 형성되어 있던 흡착대파 하부로 이동하였다. DOC의 상당 부분이 활성탄여과지에 서식하는 미생물 작용에 의해 분해 제거되는 것으로 나타났으며, 운전개시 126일 후의 BAC에서 활성탄 표층으로 부터깊이 20 cm 부근에 미생물이 1.1*10^7 cell/cm^3 이상 존재하는 것으로 관찰되어 생물활성탄 조건을 만족시키고 있었다. This study was carried out to evaluate the pollutant removal efficiencies of the advanced drinking water treatment using mated carbon process. For raw water, Nakdong river was used. From the activated carbon adsorption experiment, the following results were obtained. The efficiency of water treatment enhanced with increase in empty bed contact time. Variation of pH was not detected to the bed depth, but DO content gradually decreased with the bed depth, Removal efficiency of KMnO₄ consumption, UV254 absorption, DOC and THMFP also were increased by increasing in the bed depth. Transition of adsorption zone from upper parts of the bed to the lower parts were detected as treatment periods increased. Large portion of DOCs were degraded and removed by the microbes growing on the surface of activated carbons. Cell numbers of microbes were estimated over 1.1 × 10 exp(7) cell/㎤ at the depth of 20 ㎝ from the surface 126 days after starting operation. The results shown that the activated carbon filter was successfully acted as a biofilm filter.

제품평가 및 구매의도에 영향을 미치는 적개심 프라이밍 효과

강동균(Kang Dong-kyoon) 한국상품학회 2006 商品學硏究 Vol.24 No.1

  An experiment was conducted to investigate effects of animosity priming on product evaluation and purchase intention. Priming of animosity toward a product"s country of origin had a negative effect on product evaluation only when the product was atypical of those manufactured in the country. However, animosity priming had an adverse effect on purchase intention regardless of product typicality. The implications of these findings for various research areas are discussed and future research directions are suggested.

강시용(Si-Yong Kang),류기중(key Zung Riu),강영길(Young Kil Kang),강봉균(Bong Kyoon Kang),김동섭(Dong Sub Kim),박인숙(In Sook Park),송희섭(Hi Sup Song) 한국자원식물학회 2005 한국자원식물학회지 Vol.18 No.3

Newly introduced two lines of apios (Apios americana Medikus, red-vine and green-vine) were grown in Jeju island, to clarify their growth and production characteristics as well as to develope as a new edible crops in Korea. Both lines bloomed but did not develop to pod and seed. The red-viny line showed the habit of more early growth and maturity compared with green-viny line. Fresh tuber yields per 10a harvested in late November ranged from about 500kg to 800kg as according to the lines and cultural condition. Fresh tuber yield of red-viny line was relatively greater than that of green-viny line, mainly due to their higher tuber number per plant. Among the planting dates(April 1, April 16 and May 1) of seed tubes, highest tuber yield was obtained on May 16 planting. And the stacking cultivation culture was better than non-stacking cultivation in respect of tuber yield and disease avoidance. These results indicate that apios can produce in Jeju island, and in order to extend its cultivation to farmers it will be needed to develope some cultivars with high yields as well as labor-saving cultivation methods.

Are Korean Patients Different from Other Ethnic Groups in Total Knee Arthroplasty?

( Dong Kyoon Kim ),( Min Chul Seo ),( Sang Joon Song ),( Kang Il Kim ) 대한슬관절학회 2015 대한슬관절학회지 Vol.27 No.4

Most of the implants used for total knee arthroplasty (TKA) in Asian patients have been produced based on anthropometry of Western people. Since anatomic features and life styles are different between Western and Eastern people, there would be ethnic differences in terms of conformity of implants to the patient s anatomy or clinical results after TKA. Therefore, surgeons in Asia are particularly interested in related surgical techniques and implant designs used in TKA for improved clinical results and patient satisfaction. In this review, we investigated the anthropometric differences of Koreans from Westerners. Koreans are of shorter stature, less weight, and smaller skeletal structure and have a higher incidence of constitutional varus alignment of the lower extremity. Moreover, compared to Westerner TKA populations, the proportion of female patients was large and primary osteoarthritis was prevalent in preoperative diagnosis in Korean TKA patients. Culturally, Koreans have life styles that demand high flexion positions of the knee such as squatting, kneeling, and cross-legged sitting. Although there were no notable differences in the complication and revision rates following TKA between Westerners and Koreans, the incidence of postoperative deep vein thrombosis and pulmonary thromboembolism was lower in Koreans than Westerners. We hope that further research on implant designs and more interest in TKA will improve outcomes in Korean patients.

Clinical significance of nontuberculous mycobacteria from respiratory specimens in stem cell transplantation recipients.

Kang, Ji Young,Ha, Jick Hwan,Kang, Hye Seon,Yoon, Hyoung-Kyu,Kim, Hee-Je,Lee, Seok,Lee, Dong-Gun,Jung, Jung Im,Kim, Seok Chan,Kim, Young Kyoon Elsevier Science Publishers 2015 INTERNATIONAL JOURNAL OF HEMATOLOGY Vol.101 No.5

<P>The clinical importance of the isolation of nontuberculous mycobacteria (NTM) from respiratory specimens of stem cell transplant (SCT) recipients is not clear. We investigated the characteristics and clinical impact of NTM isolation in this population. Medical records of adult patients who underwent SCT at the blood and marrow transplantation center at a University Hospital in South Korea between January 2004 and December 2013 were retrospectively reviewed. Twenty-five of 2,658 patients were enrolled, an incidence of 0.94%. The most common NTM species isolated were Mycobacterium avium complex (n = 15) and Mycobacterium abscessus (n = 5). Sixteen patients were co-infected with other pathogens, including Aspergillus species (10 cases). Nonspecific pneumonia and cavitary pneumonia were the most common radiologic patterns. Sixteen patients had underlying lung graft-versus-host disease, including bronchiolitis obliterans (10 cases) with moderate obstructive lung defects. Whereas two of 10 patients who were treated for NTM died as a result of NTM progression, one of 15 patients who were not treated died of the same cause. This study shows that the incidence of respiratory NTM detection in SCT recipients was low and its virulence was not higher than expected. As patients frequently had concomitant infections and underlying lung diseases that made radiologic evaluation more difficult, we suggest that it would be advantageous to perform repeated microbiologic studies when NTM infection is clinically suspected.</P>
