안광병,박해근 충남대학교 의과대학 지역사회의학연구소 1987 충남의대잡지 Vol.14 No.2
Experiments were conducted in anesthesized rabbit. The both of femoral arteries were cannulated to measure the systemic arterial pressure with stetham transducer and to collect the arterial blood for measure the changes of acid-base parameters. The intracranial pressure (ICP) was increased by infusion of saline into the lateral ventricle through cannula. After measured the control data, ICP was increased to 50mmHg for 60 minute and released thereafter for recovery. The results are summerized as follows: 1. The arterial pressure was increasedtignificantly with elevated ICP. 2. The pH of arterial blood was significantly increased to 7.65±0.02 during a period of increased ICP and slowly recovered with decreased ICP. 3. The pCO_2 of arterial blood was significantly lowered with hyperventilation by the elevation of ICP. 4. Bicarbonate concentration and base excess were significantly decreased with elevated ICP. 5. Elevation of ICP induced respiratory alkalosis by hyperventilation and it was partially compensated by the kidney during a period of increased ICP. From the above results, was suggested that the Cushing reaction was important role in the higher ICP as well as act the additive role by the partially compensated respiratory alkalosis.

치조파열 및 구개열과 같은 선천성 기형은 이환된 환자에게 기능적, 심미적으로 많은 문제점을 야기하므로 정상으로 회복시켜 주는 것은 중요한 문제이다. 장기간 방치될 경우 영양장애, 구강위생 불량, 호흡기 간염, 언어 장애, 악안면 변형, 그리고 정신적인 문제 등이 복합적으로 발생할 수 있다. 따라서 구순구개열 환자의 치료는 여러 전문 치료 분야의 복합적인 접근이 필요하다. 골이식은 구순구개열 환자에 있어 중요한 치과치료 단계이다. 치아의 맹출과 치열의 안정화를 위해 치열궁은 골격손이 없이 완전해져야 한다. 또한 치열궁의 파열이 있는 부위로는 정상적인 교정적 치아이동이 곤란하다. 따라서 구순구개열 환자에 있어 골이식은 광범위하게 적용되고 있는 외과적 술식이다. 치조골을 이식함으로써 치조열은 안정화되고, 견치 또는 절치가 이식부위로 이동할 수 있게 된다. 그리고 골 이식 후, 교정을 통해 치조열 부위의 공간을 폐쇄함으로써 보철 치료 없이 치열을 재형성할 수 있다. 골이식술에는 다양한 이식재료가 사용되었다. 자가골을 이식할 경우 장골이 가장 선호되며, 그 밖에 경골, 늑골, 두개골, 하악골을 이용하기도 한다. 그리고 골이식은 골이식 시기에 따라 일차골이식, 조기 이차골이식, 이차골이식, 만기 이차골이식으로 구분할 수 있다. 이차골이식은 혼합치열기 말경에 시행되는 것을 말하며 가장 좋은 것으로 받아들여지고 있다. 영구 견치가 맹출되기 전에 이차골이식을 시행하면 인접치아의 맹출과 보존에 도움이 된다. 본 증례에서는 치조구개파열 환자의 장골에서 골을 채취하여 골 이식을 시행한 후, 골이 채워진 이식 부위에 인접 치아가 성공적으로 이동하거나 치축이 개선되고 교정치료를 통해 치열궁 배열의 만족스러운 결과를 얻었기에 이를 보고하는 바이다 Cleft lip and palate are congenital craniofacial malformation. Reconstruction of dental arch in patient with alveolo-palatal clefts is very important, because they have many problems in functions and esthetics. Malnutrition, poor oral hygiene, respiratory infections, speech malfunctions, maxillofacial deformity, and psychological problems may be occured without proper treatment during the long period of management of the cleft lip and palate. So the treatment should be managed with a multidisciplinary approach. Bone grafting is a consequential step in the dental rehabilitation of the cleft lip and palate patient. A complete alveolar arch should be achieved of the teeth to erupt in and to form a stable dentition. And the presence of the cleft complicate the orthodontic treatment. Therefore bone grafting in patients with cleft lip and palate is a widely adopted surgical procedure. Grafted bone stabilizes the alveolar process and allows the canine or incisor to move into the graft site. After the bone grafting, orthodontic closure of the maxillary arch has become a common practice for achieving dental reconstruction without any prosthodontic treatment. Various grafting materials have been used in alveolar clefts. Iliac bone is most widely fovoured, but tibia, rib, cranial bone, mandible have also been used. And according to its time of occurrence, the bone graft may be divided into primary, early secondary, secondary, late secondary. Bone grafting is called secondary when performed later, at the end of the mixed dentition. It is the most accepted procedure and has become part of treatment of protocol. A secondary bone graft is performed preferably before the eruption of the permanent canine in order to provide adequate periodontal support for the eruption and preservation of the teeth adjacent to the cleft. In this report, we report here on a patient with unilateral cleft lip and palate, who underwent iliac bone graft. The cleft was fully obliterated by grafted bone in the region of the alveolar process. The presence of bone permitted physiologic tooth movement and the orthodontic movement of adjacent tooth into the former cleft area. Satisfactory arch alignment could be achieved in by subsequent orthodontic treatment.
幼兒服飾에 關한 民俗學的 硏究 : 全南地方 出生禮를 중심으로
안혜자,나광주 서강정보대학 1999 산업과학연구 Vol.1 No.-
In the past era when the medical science was underdeveloped, one of human beings' dearest wishes was to enjoy longevity. Such desire to live long was able to be seen in places of our traditional clothing life style and in particular during the period when the infant mortality was high, people prayed that their baby might live long and invoked a blessing upon it by charms instead of medical prescriptions. Thereupon we studied infant dress and ornaments which were derived from traditionally handed-down sorceries pertaining to babies by researching 26 people over 67 years old, who were considered to have worn traditional clothes and had their parity. The result of investigation is as follows. Newborn babies had worn their "BAENAEJEOGORI" until the seventh day since their birth. So people would supplicate for their babies' longevity by sorcerous measures such as sewing "SILGOREUM". In the mean time babies' clothes needs repeated washing so that among the processes of disassembling, washing, and sewing the clothes(BAENAEJEOGORI), the process of sewing would be made simple. "BAEKIL" is the 100th day since babies were born. Babies had been usually dressed in white clothes by the day, and until the day they started to wear colorful clothes. White color of the clothes which babies had worn by "BAEKIL" was the sorcerous symbol to protect babies from an evil fortune. People also dressed their baby in "BAEKJEUKJEOGORI" in the hope that it might live long. "DOL" is the first birthday of a newborn baby and on the day a baby puts on new dress which is called "DOLBIM". "DOLBIM' is composed of a coat, trousers(for a son) and a skirt(for a daughter). A coat is called "SAEKDONGJEOGORI" : the coat is decorated with five kinds of colors which old chinese people believed symbolize the five elements of all creation(i.e. metal, wood, water, fire and earth). People believed those colors would ward off evil fortune and bring their babies longevity. Sons had on violet or gray trousers and daughters wore a red skirt with "JEUKIHEORI" ; besides they put on a pair of socks and covered their head with "GULRAE".

페그인터페론과 리바비린 병합요법은 만성 C형 간염의 일차 치료법이다. 저자들은 만성 C형 간염 환자에서 페그인터페론 과 리바비린 병합 요법 중에 발생한 벨마비 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다. 환자는 5년 전부터 만성 C형 간염을 앓아온 48세 남자이며, PEG-IFN α-2a 135μgm 피하주사 주1회와 하루 1200㎎의 리바비린을 투여하였다. 치료시작 후 9개월째 환자는 오른쪽 안면의 근력약화를 호소하였으며 벨마비로 진단되었다. 페그인터페론과 리바비린 병합요법을 지속하면서 관찰하였다. 환자의 벨마비는 페그인터페론 치료를 중단하지 않았음에도 3개월후 증상이 회복되고 이후 벨마비 재발 없이 현재 경과관찰 중이다. 만성 C형 간염에서 페그인터페론과 리바비린 병합 요법시 벨마비의 발생 가능성을 염두에 두어야 하겠다. A Case of Bell's Palsy Associated with Combination Therapy of Pegylated Interferon Alfa-2a (PEG-IFN) and Ribavirin for Chronic Hepatitis C Virus Infection Pegylated interferon alfa(PEG-IFN α) and ribavirin therapy is the first line treatment for chronic hepatitis C. Mild complications of the therapy are common, but more serious complications are rare. We report here a case of Bell's palsy that occurred in a patient with chronic hepatitis C virus infection during combination therapy of PEG-IFN α-2a and ribavirin. The patient was 49-year-old man with chronic hepatitis C (genotype 1b) for 8 years. He had compensated liver cirrhosis with splenomegaly. Therapy with PEG-IFN α- 2a 135mcg/week and ribavirin 1200mg/day was initiated. After 9 months of the therapy, the patient showed a loss of muscular tone on the right side of his face. A diagnosis of Bell's palsy was made. The Bell's palsy resolved over 3 months despite continuation of the combination therapy.
A 2nd Order Harmonic Compensation Method for Wind Power System Using a PR Controller
Hae-Gwang Jeong,이교범,Jong-Hyun Lee 대한전기학회 2013 Journal of Electrical Engineering & Technology Vol.8 No.3
This paper proposes a compensation method for the 2nd-order harmonic of single-phase grid-connected wind power generation systems. Theoretically, a single-phase grid-connected inverter system has no choice but to cause the 2nd-order harmonic to DC-link voltage. The reference active current is affected by the DC-link voltage. The output current from the reference active current is distorted by the 1st and 3rd-order harmonic. The proposed method can compensate, conveniently, the reference active current with the 2nd-order harmonic. To reduce the 2nd-order ripple in the reference active current, proposed method takes a PR controller as a feed-forward compensator. PR controllers can implement selective harmonic compensation without excessive computational requirements; the use of these controllers simplifies the method. Both the simulation and experimental results agree well with the theoretical analysis.
