1.Web-based Monitoring of Infant Incubators.
Journal of Korean Society of Medical Informatics 2001;7(4):69-74
Infant Incubator is the most important equipment in a infant ICU. This maintain adequate temperature and humidity for survival of infants. The final object of this research is Web-based monitoring of several infant incubators in ICU. To realize these objects, we developed a temperature/humidity sensing module which is interfaced to Web server board via RS485 port. We used a small micro controller in each sensing module. So the size of this module is small enough to be attached to incubator. We can access each sensing module with RS485 port on Web server board via network. As a first trial, we networked 4 infant incubators. The operator can send alarms to each incubator and these alarms are indicated with sounds and lights on measurement module. Our system can increase the convenience by a intensive central monitoring, so instant handling to some kinds of accident is possible.

PURPOSE: We describe clinical assessment of visual internal urethrotomy (VIU) as primary treatment modality in 69 men who presented with complete or partial obstructed urethral stricture. MATERIALS AND METHODS: The 63 patients with partial obstructed urethral stricture were treated by typical VIU. The 6 men with complete obstructed urethral stricture were treated by VIU using sound passed through previously placed suprapubic tract as guide. RESULTS: The procedure was completed successfully in 57 of the 63 men with partial obstructed (90.5%) and 3 of 6 patients with complete obstructed urethral stricture (50%). CONCLUSIONS: VIU is a safe and effective as primary treatment plan when urethral stricture is partial obstructed and the impassable urethral segment is shorter than 1.0cm.

OBJECTIVE: As the rapid progress of aged society, there must be solutions of preparation against unpredicted accidents for aged solitary people. The most important thing that we must consider is the unconstraint of daily life. So, we are to develop a system and algorithm which meet our objectives. METHODS: We have monitored the degree of activity of the aged solitary person. The CCD camera was used not to disturb the daily activity and we evaluated the degree of activity using image processing on personal computer. The activity monitoring during night was assumed by sleeping on the bed, so the major method was breath monitoring during sleeping. On the other hand, daily activity was monitored by wide viewing camera in the living room. To prevent the privacy trouble, the acquired image was converted to binary form and the degree of breath and moving factor was estimated. RESULTS: In this paper we propose a new processing algorithm to accurately measure breathing characteristics in sleep apnea sufferers. We improved the conventional center-of-mass method and further applied the projection-profile method. As a result, we have improved breath measurement accuracy. In a comparison with conventional polysomnography, our method was 92% effective in detecting apnea cases. CONCLUSION: As a result of this study, we can monitor sleep apnea more simply and with no sleep interference. In measuring the activity of daily life, these improved algorithms were applied. So, we established a monitoring method of no-constrained, quantitative measurement for the aged solitary people during the whole day.

Journal of Korean Neurosurgical Society 1991;20(7):577-583
The omentum has been used over the years for a variety of clinical problems. Recently it has shown that placing the omemtum on the brain and spinal cord can lead to an extensive development of vascular connections at the omental/CNS interface. Success with omental transposition to the human brain has led to increasing intreast in placing the omentum onto the human spinal cord. One paraplegic patient was chosen to enter into a feasibility study to see if omental transposition to their spianl cord might result in clinical benefit. The length of time from injury was about 21 months respecively. This patient had little, if any, motor and sensory function below umbilicus level. The operation required surgical lengthening of the pedicled omentum followed by its placement into a subcutaneous tunnel created backward along the lateral chest wall up to T-10, 11 level. An extensive thoracic laminectomy was then performed followed bya wide opening of the dura. In our case the cord showed segmental shrinkage of the spinal cord consistent with previous trauma. The omentum was laid directly onto the underlying spinal cord. Our observation for five months has shown that placement of the omentum onto the chronically injured spinal cord allowed for subsequent improvement in neuroelectrical activity, as manifested by reproducible somatosensory evoked potentials, and, more importantly, in moter function. It is considered that placing the omentum directly upon the brain or spinal cord may have the effect of either improving local vascular perfusion or, possibly, exerting some biochemicals(neurotransmitter), or as yet unknown, influence. But further observation is warranted to determine whether this improvement will be continued and will be observed in another cases.

BACKGROUND: Recently in Europe, some epidemiologic studies reported that various physical symptoms and social, psychological wellbeing are related to low blood pressure. But in Korea, none has been studied on symptoms related to low blood pressure yet. In this study, we would like to see if the somatic symptoms and social, psychological wellbeing shown t,o be related to low SBP is truly associated with it. METHODS: Questionnaire interview was done to the people who have visited Department of family practice in two university hospitals and two health promotion center from April, 1996 to August, 1996. Seven somatic symptoms and Psychosocial Wellbeing Index(PWI) for the evaluation of social, psychological health status were included in the questionnaire. SAS statistics packages was used in statistical precess. We used logistic regression to see the frequency of somatic symptoms related to the systolic blood pressure(SBP) group and the confirmation of confounding variables was done by ANOVA. RESULTS: Total of 304 completed the questionnaire. Average age was 44 years old and average SBP was 115.4+/-16.4. 84 of them (27.6%) felt that they had a low BP & 69 were women compared to 21 men, being meaningfully more common. 107(35.2%) people answered that they had heard that their blood pressure was low and 66% were from doctors. Only 32(38.1%) of the group who felt of having hypotensive symptoms and 38 of the group who heard of having hypotension actually had SBP of below 100 mmHg. Vocation, income, smoking & alcohol history, present illness, marital status were not significant as a confounding variable. SBP of 100 or below group had a less presentation of fatigue & significantly higher PWI than the group of above 100mmHg (p<0.05). The group who felt that they had a low BP had more complaints of fatigue, dizziness, palpitation, cold hands and feet and had significnatly higher PWI than the group who didnt. CONCLUSIONS: SBP of 100mmHg or below group has more frequent manifestion of fatigue and low level of sociopsycholgiacl health index than the above 100mmHg group. But most of the people who complained of hypotensive symptoms didnt have low blood pressure and a lot of them misunderstand of having low blood pressure and after checking blood pressure by doctors, so great deal of caution is called for when seeing patients.

7.What Happens When the Items of Examination and Correct Answer Is Opened in Medical School?.
Korean Journal of Medical Education 2001;13(1):143-148
After opening of the item of examinations and correct answer, the objection on the answer or item itself was received through internet board from students in medical school. The behavioral change of students and professors was evaluated after this system. A total of 81 examinations was subjected in second semester of year 1999 and in year 2000 in Hallym University, Korea. Out of 5,478 items, 182 became targets of objection(3.4%). Of 182 items, 83 ones were revised according to the students opinion(45.6%). Although the rate of objection increased from 2.4% in 1999 to 4.0% in 2000, the rate of revision decreased from 59.3% in 1999 to 39.8% in 2000. Total revision rate was not significantly different between year 1999, 1.4 % and year 2000, 1.6 % (p=0.7080). This kind of opening of items and answers gave students a chance to discuss on items once again and to learn contents by feedback. Most of students want to maintain this kind of system after examination. It also made professors develop better and more lucid items. This is one of good examples of using internet in the evaluation of medical education.

Journal of Korean Neurosurgical Society 2005;37(6):405-409
OBJECTIVE: The purpose of this study is to assess the factors related to the outcome of 84 patients who underwent surgery for anterior communicating Artery(ACoA) aneurysms. METHODS: The authors review 84 patients who were undertaken from January 1998 to May 2004. In the management of ACoA aneurysms, the outcome was based on several factors: Clinical condition, Distribution of hemorrhage, Time between aneurysmal rupture and surgery, Direction and shape of the aneurysm. RESULTS: The incidence rate of the ACoA aneurysm was 35%. Seventy four patients were classified as those having a good recovery, but 5 patients suffered from some morbidity and 5 patients died. The rate of good outcome for the patients with Hunt and Hess grade was as follows 100% in grade I, 95% in grade II, 80% in grade III, IV and V. The rate of good outcome for the patients with Fisher grade was as follows 98% in grade I, II and 81% in grade III, IV. Nineteen of 22 patients who underwent early surgery were rated as good, while twenty six of 30 patients for whom surgery was delayed showed a favorable result. The unfavorable outcomes were also attributed by vasospasm or other medical problems. CONCLUSION: For further improvement of the overall surgical outcome: First, early surgical intervention is recommended for good grade patients. Second, active management of poor grade patients should be scrutinized with early surgery. Third, it is also important to step up the effort to minimize the risk of medical complications to enhance surgical results on top of the mainstay of prevention efforts for vasospasm and rebleeding.

PURPOSE: The aim of study was to review the results of open surgical repair (OSR) of chronic juxtarenal aortic occlusion (JRAO). MATERIALS AND METHODS: We retrospectively reviewed the results of OSR performed in 47 patients (male, 92%; mean age, 59.9+/-9.3 years [range, 44-79]) with chronic JRAO during the past 21 years. In order to reduce intraoperative renal ischemic time (RIT), we excised a portion of the occluded segment of the infrarenal aorta without proximal aortic clamping. We then performed suprarenal aortic clamping with both renal arteries clamped, removed the proximal aortic thrombus cap, confirmed both renal artery orifices, and moved the suprarenal aortic clamp to the infrarenal aorta to allow renal perfusion and standard aortoiliac reconstruction. We investigated early (<30 days) postoperative surgical morbidity (particularly renal function), operative mortality, and longterm patient survival. We conducted risk factor analysis for postoperative renal insufficiency. RESULTS: The mean intraoperative RIT was 10.7+/-5.5 minutes (range, 3-25), including 6 patients who underwent concomitant pararenal aortic thromboendarterectomy. Postoperatively, five (11%) patients had transient renal insufficiency, one had pneumonia, and one patient had an acute myocardial infarction. However, there was no operative mortality or newly developed dialysis-dependent renal failure. Postoperative follow up was available in 36 (77%) patients for a mean period of 6.3 years (range, 1 month-17 years). Kaplan Meier calculations of patient survival at 5 and 10 years after surgery were 91.2% and 83.6%, respectively. CONCLUSION: We have experienced short RIT, acceptable early postoperative results and long-term survival after OSR of chronic JRAO.

OBJECTIVE: The aim of this study is to determine the treatment strategies for the poor grade patients with aneurysmal subarachnoid hemorrhage(SAH) with respect to the timing of surgery. METHODS: We have analyzed 51 patients of Hunt and Hess grade IV and V at admission among 140 SAH patients who were managed during recent three years. They were devided into two groups according to the interval between SAH and surgery: 30 early treatment group(operated within 3 days) and 21 delayed treatment group(6 delayed operation cases and 15 unoperated cases). RESULTS: Clinical outcome of early surgery group was favorable(Good or Fair) in 23 cases(76.7%) and unfavorable in 7 cases(23.3%, 2 Poor, 5 Dead). On the contrary, those of delayed surgery group or without surgery group was favorable in 4 cases(19.1%) and unfavorable in 17 cases(80.9%, 1 Poor, 16 Dead). Overall management outcome of poor grade SAH patients was favorable in 27 cases(52.9%), unfavorable in 24 cases(47.1%) and mortality rate was 41.2%. Unfavorable outcome in poor grade SAH patients was largely affected by the initial hemorrhage and subsequent development of intractable intracranial hypertension(Hunt and Hess grade IV: 5 cases, grade V: 8 cases), cerebral infarction(grade IV: 3 cases, grade V: 1), rebleeding(grade IV: 3 cases), and surgical complication(4 cases). CONCLUSION: An active treatment policy including early surgery might achieve a better outcome of poor grade SAH patients.
