The requirements for the optimal building system design is numerous. However, most system designers do not take care of various design strategies. They often argue that the proper simulation tools are not existed to solve the implicated design requirements and the time to consider many alternatives of building systems are insufficient. The aim of this study is to develop the optimization interface program that considers various system design variables and eventually find both the optimal values of annual energy use and cost. Therefore, Doe2Opt is developed to easily perform simulation-optimization process based on DOE2 and GenOpt, and minimizes energy cost of small-to-medium sized building for 6.7% and that of large sized building for 3% with optimizing several HVAC system variables.

Anomalies of the coronary arteries originating from the right sinus of Valsalva

허정호 고신대학교(의대) 고신대학교 의과대학 학술지 2007 고신대학교 의과대학 학술지 Vol.22 No.1

Anomalous origin of left and right coronary arteries from a single coronary ostium in the right sinus of Valsalva is rare. Accordingly, few reports have described this anomaly. We report a case of a 70-year-old woman with left and right coronary arteries originating from the right sinus of Valsalva. Coronary anomalies are associated with increased mortality, depending on the myocardium at risk. A left main originating from the right coronary sinus is supplying a greater extent of the myocardium and is associated with both an increased incidence of symptoms and of sudden cardiac death. The possibility of such an artery anomaly should always be considered in patients with a history of chest pain or syncope.

1. The number of average milking cows, clinical forms of mastitis, mastitis-developing cows, and cows killed by mastitis a year were 25.7, 1.8(7%), 6.3(26%), and 2.7(10.1%)heads, respectively. The annual grade changes of standard plate counts(SPC) and somatic cell counts(SCC) showed the grade 1A of SPC diminished sharply from April to August, we think it was due to the lack of proper management in farming season and the grade 3 of SCC indirectly influenced increased in huge during August. 2. The average number of parturitions of farms was 2.3, but 50% of below 1 parturition were 22 farms(31%), 50% of above 3 parturitions were 16(23%) out of 71 farms. According to grades of the number of parturitions of milking cows per each farm, the farms' grades recording 3 parturitions and 50% were little bit excellent. 3. The actual situation research of foremilking CMT revealed 35 out of 74 farmer didn't do CMT Among them(35 out of 74 farmers), 80% did not test thanks to the troublesome process of the CMT. SCC grade 3, among farms who did foremilking CMT once or twice a month and who did not were 29% and 40% respectively and SPC grade 1A were 55% and 9%, respectively. 4. The research of actual situation on milking management let us know 29 farms(39%) did not do lastmilking, 37 farms(49%) usually did overmilking, and 34 farms(46%) did milking for 4 or 5 minutes. Grades according to average requiring times of milking showed SCC grade 1 of farms milking within 7 minutes was 11% and SPC grade 1A was 34%, on the other side, farms milking more than 7 minutes were 0% in SCC grade 1 and 13% in SPC grade 1A. Grades according to the starting time of milking after rubbing teats showed SPC grade 1A of farms starting milking at about 1 minute and over 2 minutes were 50% and 20%, respectively. 5. The research of actual situation on hygienic milking management uncovered 65 farms(88%) were using one towel which was used in washing teats and udders to wash more than 3 to 4 cows, and 53 farms(72%) were using one dried towel to dry udders not for each cow but for more than 3 to 4 cows after washing. Also, on milking turns disclosed 30 farms(40%) were milking cows in the order of incoming without isolation of a dominant group. According to grades of towels used in washing teats and udders, farms using a towel for each cow were 56% and a towel for over 3 cows were 31% in SPC grade 1A. According to using-or-not grades of dried towels after washing udders, farms using a towel for each cow were 79% and a towel for over 3 cows were 21% in SPC grade 1A. 6. Farms doing teat-dipping before milking were 7(10%), not doing teat-dipping after milking, or doing sometimes were 9(12%), and doing right after milking were 57(77%). And farms doing teat-dipping after dry cows and before delivery were 21(28a ). Farms using bethadine as an antiseptic solution were 70(95%), 40 farms(59%) diluted it with water as weak as 5 to 10 times, and on drying cows 64 farms(87%) slowly did it more than 2 days. Grade 1A of SPC of farms doing teat-dipping at every milking was 38%, farms doing occasionally or not was 33%, and farms doing it right after milking was 37% and doing after milking more than 5 cows was 20%. Grade 1A of SPC among farms diluting bethadine 5 times and diluting 5 to 10 times with water were 36% and 33%, respectively, and Grade 3 of SCC were 35% and 32%, respectively. 7. Studies on nonlactating period medical treatment, as the cows were on dry, 54 farms treated with their own hands.73 farms(98%) had bovine mastitis treated for themselves. And on applying medicines against mastitis, 55 farmers chose them on the basis of their own experience, 42 farms(57%) were treated more than 3 days. 41 farms(55%) dumped away the mastitis infected milk separately, 24 farms(32%) were feeding and milking at the same time. 8. Fifty-six farms(76%) always washed and disinfected milking machines after milking. Farms using the milking machines at low, or variable vacuum pressures, or at the vacu

Painless Thoracic Aortic Dissection Presenting as High Paraplegia

허정호 고신대학교(의대) 고신대학교 의과대학 학술지 2007 고신대학교 의과대학 학술지 Vol.22 No.1

Acute aortic dissection is a catastrophic episode that usually presents as a sudden, painful, ripping sensation in the chest or back. Physical findings may include loss of pulses and aortic regurgitation. It is associated with neurologic sequelae in as many as one third of patients. Painless dissection occurs in 5% of patients. We report a case of painless aortic dissection, presenting as acute paraplegia. The patient was a 59-year-old man who presented with paraplegia, with no chest or back pain. On examination, strength was 5/5 in both upper extremities and 0/5 in both lower extremities. Computed tomography of the chest revealed a type A dissecting aneurysm. Painless acute aortic dissection in which paraplegia is the only presenting sign is very rare. However, aortic diseases, including acute aortic dissection, should always be considered as a differential diagnosis of patients with sudden onset, painless paraplegia.

중증 악성 담도 협착에서 Soehendra 배액관 제거기를 사용하여 성공한 담도 배액술: 3예 보고

Malignant biliary or pancreatic duct stricture is dilatated using dilatating catheter or balloon catheter but a high grade stricture is difficult to dilate by general dilatating methods. Using Soehendra stent retriever is an effective method for exchanging an impacted stent. Recently, high grade malignant biliary strictures have been dilatated by Soehendra stent retriever. We report 3 cases of successful biliary drainage in high grade malignant biliary strictures using 7 Fr Soehendra stent retriever. (Korean J Gastrointest Endosc 2002;24:62-65) 담도계의 악성 질환이 있을 때 내시경적 역행성 담도 배액술 등의 비수술적 담관 배액술을 시행한다. 이 때 협착 부위의 확장은 일반적으로 확장용 카테터나 풍선 카테터를 사용하여 확장한다. 그러나 중증의 협착은 일반적인 확장 방법으로는 쉽게 확장되지 않는다. Soehendra 배액관 제거기는 담도 내에 파묻힌 배액관을 제거하는 데 효과적인 기구이다. 하지만 최근에는 중증의 악성 담도 협착의 확장에 Soehendra 배액관 제거기를 사용하고 있다. 저자 등은 중증의 악성 담도 협착의 환자에서 Soehendra 배액관 제거기를 사용하여 배액술을 성공시킨 3예를 보고하는 바이다.
