유다연,권차욱,곽지민,백화현,김이조,차경애 대구대학교 정보통신연구소 2010 情報通信硏究 Vol.7 No.1
데이터 글러브(Data Glove)는 손 제스처를 정의하여 시스템을 제어하는 입력장치로 가상현실기술 및 교육, 의료, 산업분야에서 많이 사용되고 있다. 이는 가상현실 속에 존재하는 사물을 현실에서 제어하게 함으로써 사용자에게 마치 현실 세계의 사물을 제어하는 느낌을 주는 장점을 가지고 있다. 이에 본 논문에서는 이러한 데이터 글러브의 장점을 이용하여 3차원 게임에 적용시키는 방법을 제안한다. 먼저 데이터 글러브로 제스처를 정의하고, 트래커(Tracker)와 연동하여 시스템을 구현한다. 구현된 시스템을 실험하기 위해서 OpenGL로 인형 뽑기 게임을 구현하고 사용자가 데이터 글러브를 착용 후 정의된 제스처를 통해 게임을 제어하도록 한다. 본 논문에서 제안한 방법은 사용자들에게 좀 더 높은 몰입감을 제공하며, 향후 게임 산업 발전에도 많은 영향을 줄 것으로 기대한다.

본 연구는 한국 재래 산양 112두와 유산양인 Saanen종 7두의 혈액으로부터 genomic DNA를 추출하고, PCR-RFLP 방법에 의해 β-casein 유전자의 특성을 분석하여 한국재래산양의 효율적인 유전자원의 보전 및 개량을 위한 기초 자료로 제공하고자 실시하였다. 한국재래산양의 genomic DNA로부터 PCR기법을 이용하여 β-casein의 유전자좌를 증폭한 결과 각각 481bp 크기의 단편이 양호하게 증폭되었음을 확인하였다. β-casein 유전자좌의 증폭산물에 대한 Bal Ⅰ의 제한효소를 처리한 결과, β-casein AB형은 481bp, 284bp 및 197bp의 단편을, 그리고 BB형은 284BP와 197BP의 단편을 한국재래산양과 유산양인 Saanen 종에서 확인 할 수 있었다, 유전자형 빈도에 있어서는 한국재래산양에서 β-casein AB 및 BB의 빈도는 각각 6.25 및 93.75%이었고, 유산양인 Saanen 종은 각각 57.14 및 42.86%이었다. 유전자빈도에 있어서는 한국재래산양의 β-casein A 및 B의 빈도가 각각 0.031 및 0.969이었고, Saanen 종에서는 각각 0.286 및 0.714의 빈도를 보였다 한국재래산양의 β-casein 유전자의 염기서열과 이미 보고되어 있는 goat의 염기서열(GeneBank accession Number M90556)간에는 총 11개의 염기서열에 차이를 나타내어 97.71%의 상동성을 보였다, 따라서 한국재래산양의 β-casein 유전자의 다형성과 염기서열 분석에 의한 분자유전학적 특성의 규명은 한국재래산양의 유전자원의 보전 및 개량을 위한 기초 및 응용 자료로 이용될 수 있을 것으로 생각된다. This study was performed to provide the basic data for preservation and improvement of genetic resources according to finding genetic construction obtained from analysis of genetic characteristics of β-casein gene in Korean Native goat and Saanen using the PCR-RFLP. This study confirmed the amplified products of 481bp fragments obtained from the amplification of β-casein loci by PCR. The β-casein AB genotype showed 481, 284 and 197bp, and β-casein BB genotype showed 284 and 197bp fragments in Korean Native goat and Saanen. The frequencies of β-casein genotype in Korean Native goat were 6.25 and 93.75% for AA and AB and the frequencies of β-casein genotype in Saanen were 57.14 and 42.86% for AA and AB types. The frequencies of β-casein A and B alleles were 0.031 and 0.969 in Korean Native goat and the frequencies of β-casein A and B alleles are 0.286 and 0.714 in Saanen, respectively. The nucleotide sequence of β-casein gene of Korean Native goat was 97.71% higher homology with 11 nucleotide sequences difference of that of goat reported in GeneBank (M90556). Therefore, this study of molecular genetic characteristics by the analysis of genetic polymorphism and sequencing for β-casein gene should be used as basic and applying data for preservation and improvement of genetic resources in Korean Native goat breeding.

To develop a clotrimazole-loaded solid suppository with poloxamer and propylene glycol, the melting points of various formulations composed of poloxamer 188 (P 188) and propylene glycol were investigated. The dissolution study of clotrimazole delivered by the suppository composed of P 188 and propylene glycol was performed. The mixtures composed of P 188 and propylene glycol were homogeneous. Propylene glycol affected the melting points of poloxamer mixtures. In particular, the mixture [P 188/propylene glycol (70/30%)] with the melting point of about 32°C was a solid form at room temperature and instantly melted at physiological temperature. Furthermore, propylene glycol affected greatly the dissolution rates of clotrimazole from the suppository. Dissolution mechanism analysis showed the dissolution of clotrimazole was proportional to the time. Our results indicated that the solid suppository with P 188 and propylene glycol would be a candidate of rectal dosage form for clotrimazole.

Pheochromocytoma is derived from the chromaffin tissue. This tumor is characterized by a combination of various clinical manifestations that include the paroxysmal hypertension, severe headache, palpitations and diaphoresis. In addition, hyperglycemia can be caused by the excess of catecholamines or other bioactive substances. Pheochromocytoma during pregnancy is rare and associated with very high maternal and fetal morbidity and mortality. We present case a 27-year-old pregnant woman at 22th weeks of gestation with uncontrolled hypertension and gestational diabetes mellitus. She was admitted with an initial diagnosis of preeclampsia. Ultrasound revealed a right adrenal mass and biochemical test and MRI imaging were compatible with pheochromocytoma. Laparoscopic adrenalectomy was performed and her blood pressure and blood sugar level was normalized without medication after adrenalectomy. The diagnosis of pheochromocytoma in pregnant patients is often missed because these tumors have the ability to produce signs and symptoms that mimic other forms of hypertension and diabetes, including the gestational hypertension, gestational diabetes mellitus and preeclampsia. Therefore, clinicians should consider pheochromocytoma as differential diagnosis in pregnant patients with uncontrolled hypertension and diabetes.

브랜드 아이덴티티(Brand Identity)는 기업의 상품과 서비스에 대한 소비자들의 심리적 인지활동에 영향을 주는 핵심 자산이 다. BI 디자인 개발의 초기 기획 단계에는 기업 고유의 차별화된 접근 전략이 요구되고, 더불어 마지막 BI 디자인 평가단계에서는 잠재 소비자들을 활용한 합리적인 디자인 평가 방법이 모색될 필요가 있다. 하지만 전통적인 BI 디자인 평가 과정은 대다수가 설문조사에 의존함으로써 해당 과정에서 발생하는 피험자들의 ‘왜곡된 심리 표출 현상’으로부터 자유로울 수 없는 경우가 발생한다. 본 연구는 다수의 BI 디자인 시안에 대한 우선순위의 선호도 조사 방식에 덧붙여, 피험자의 뇌파측정 데이터를 활용하는 방식이 BI 디자인 평가 과정에 도움이 될 수 있는지 여부를 탐색하였다. 이를 위해, 피험자 선호도 조사 결과와 피험자뇌파측정 데이터의 상관관계를 파악하였으며, 이 과정에서 ‘매력성’과 ‘집중도’를 변수로 활용하였다. 그 결과, ‘매력성’에 관한선호도 조사 결과와 ‘집중도’에 대한 뇌파 측정 결과의 상관관계가 높음이 파악되었다. 따라서 기존의 전통적인 정성적 평가방식에 덧붙여 뇌파를 활용한 디자인 평가 방법이 BI 디자인과 같은 암묵적 지식 대상을 평가하는데 유용함을 확인하였다. Brand identity (BI) is a key asset that affects consumers psychological cognition of products and services. In the initial planning stage of the BI design development for a company, a unique approach strategy is required. In the final evaluation stage, a reasonable design evaluation method involving potential consumers needs to be prepared. However, conventional brand identity design evaluation processes tend to depend on the results of surveys, and in many cases it is impossible to be free from the distorting phenomenon of survey respondents’ psychological manifestation which is often revealed in the process of the surveys. In this context, this research has explored whether the method of utilizing EEG data of the subjects along with the conventional survey method of preference could be helpful in the process of evaluating the brand identity design. To achieve that, we correlated the subject s preference survey results with the subject’s EEG data. Attractiveness and concentration were used as variables. As a result, it was found that there was a high correlation between the results of preference survey on attractiveness and the results of EEG on concentration . Therefore, in addition to the existing conventional qualitative evaluation methods, we confirmed that design evaluation methods using EEG are useful for evaluating tacit knowledge objects such as the BI design.

Purpose: Acute alcohol intoxication (AAI) causes various complications such as electrolyte imbalance, alcoholic ketoacidosis (AKA), rhabdomyolysis, and acute kidney injury (AKI). Although there have been some reports about AKA and rhabdomyolysis, AKI due to acute alcohol intoxication is rarely reported. Methods: We retrospectively evaluated the medical records of 371 patients with AAI between January 2004 and May 2010 in Uijeongbu St. Mary`s Hospital. We compared the clinical findings, morbidity and mortality rate between AKI and normal kidney function (NKF) groups. Results: Of the total 371 patients with AAI, AKI occurred in 107 patients (28.8%). The peak serum creatinine level in AKI patients was 2.9±1.9 mg/dL. Thirteen of the 107 patients (12.1%) received renal replacement therapy. AKI group had higher incidence of decreased mentality (29.0% vs 16.3%, p= 0.006), dyspnea (11.2% vs 4.9%, p=0.029) and hypotension (66.0% vs 41.7%, p<0.001), and lower incidence of gastrointestinal bleeding (22.4% vs 34.8%, p=0.019), compared to NKF group. The AKI group also had higher incidence of ketoacidosis (78.5% vs 28.8%, p<0.001), rhabdomyolysis (19.6% vs 4.2%, p<0.001), and pneumonia (22.4% vs 8.0%, p<0.001), compared to NKF group. The length of ICU stay was longer (7.4±10.8 vs 4.1±6.1 days, p=0.003) and the mortality rate was higher (17.8% vs 2.3%, p<0.001) in AKI group. Conclusion: This study demonstrated that incidence of AKI in patients with AAI was 28.8% and AKI was associated with high morbidity and mortality. And multivariate analysis demonstrated that independent risk factors of AKI were ketoacidosis and increased serum osmolality.
