Objectives : To evaluate the anatomic variations of the paranasal sinuses on computed tomographs. Material and Methods : The author examined the CT images of the paranasal sinuses retrospectively in 500 patients who visited Chonbuk National University Hospital between January 1996 and December 1997. Results : The highest incidence of anatomic variation of the paranasal sinuses in bilateral structures was agger nasi cell(73.2%), followed by concha bullosa(31.1%), Onodi cell(24.0%), Haller cell(19.8%), maxillary sinus septum(13.0%), paradoxical middle turbinate(2.5%), pneumatized uncinate process(2.0%), and bent uncinate process. The highest incidence of anatomic variation in midline structures was nasal septum deviation(53.2%), followed by nasal septum aerated(29.4%), bulla galli(24.7%) asymmetric intersphenoid septum(22.3%), and nasal septum spur(13.8%). The correlation between anatomic variation and paranasal sinusitis was not found. Conclusions : The results of this study will aid in the diagnosis and treatment of paranasal sinus diseases, especially in the treatment planning before functional endoscopic surgery.(J Korean Oral Maxillofac Radiol 1999;29:477-492)

기계적 응력은 정상적인 발달과정 동안 조직의 항상성에 있어 중요한 역할을 한다. 기계적 응력은 치아 이동과 저작과 같은 상황을 포함한다. 치아 이동과 저작 중에 치주인대 섬유모세포는 기계적 자극을 감지하고 주위의 세포밖 물질과 생체분자 대사의 변동에 의해 반응을 보인다. 그러나 아직까지 기계적 응력 하에서 치주인대 세포에서 발현된 유전자에 관한 연구는 미비한 실정이다. 최근 기계적 응력이 초파리에 존재하는 UNC-50 유전자에 영향을 줄 수 있다고 보고되었다. 또한 UNC-50은 치은 섬유모세포와 비교해 치주인대 섬유모세포에서만 발현된다고 보고되었다. 본 연구에서는 간헐적 교정력 적용 시에 백서의 치아에서 일어나는 치근 및 치주 조직의 조직학적 변화와, UNC-50의 발현 양상을 면역조직학적 염색으로 조사하여 치주인대에서 기계적 응력과 UNC-50의 관련성을 알아보고자 하였다. Sprague-Dawely계 수컷 백서 12마리를 4마리씩 세 군으로 나누어 상악 우측 구치부에 NiTi closed coil spring을 사용하여 40 g 정도의 견인력이 발생하도록 하여 하루에 1시간씩 간헐적인 교정력을 적용한 후 1, 3, 5일 후 치주인대의 조직학적 변화를 관찰하여 다음과 같은 결과를 얻었다. 조직학적 소견에서 상악 제1대구치 근심구개치근의 치근부 1/3에서 압박측은 안장측보다 더 좁은 치주인대공간을 보였고 교정력을 적용시킨 후 3일 후부터 인장측에서 백악모세포 활성으로 인한 백악질 침착이 관찰되었다. UNC-50은 인장측의 분화 중인 백악모세포에서 강한 발현을 보였다. Osteocalcin은 인장측에서 압박측에 비해 신생 백악질에 존재하는 분화 중인 백악모세포를 따라 강한 발현을 보였다. 이상의 연구결과는 UNC-50이 간헐적 교정력 즉 기계적 응력의 변화에 따른 백악모세포의 분화과정에 중요한 역할을 함을 나타낸다. 그러나 이를 명확히 하기 위해서는 교정력 적용 후 UNC-50의 세포내 신호전달과정에 대한 보완연구가 필요할 것이다. Objective: Periodontal ligament fibroblasts have an ectomesenchymal origin and are thought to play a crucial role for not only homeostasis of periodontal tissues but also bone remodeling, wound healing and regeneration of tissues. Recently, it has been reported that UNC-50 is not expressed in gingival fibroblasts but in PDL fibroblasts. The purpose of this study was to examine the expression of UNC-50 and osteocalcin in the periodontium after application of intermittent force. Methods: Twelve rats had 40 grams of mesially-directed force applied at the upper molar for 1 hour/day. Four rats were sacrificed at 1, 3 and 5 days. Immunohistochemical localization of UNC-50 and osteocalcin antibody was carried out. The results showed apposition of new cellular cementum and a slight increase in periodontal space at the tension side. Results: Strong UNC-50 expression was observed in the differentiating cementoblasts close to PDL fibroblasts in the tension side whereas it was barely expressed at the compression side. Expression was strong at day 3, and decreased at day 5. Osteocalcin immunoreactivity expression was strong in differentiating cementoblasts at the tension side. Conclusion: It can be suggested that UNC-50 is related to the differentiation of cementoblasts, and may be responsible for the molecular event in PDL cells under mechanical stress.

The purpose of this study was establish the basic material for assisting in raising the quality of nursing service for nurses in the nursing home. For this purpose it attempted to identify the demand of nursing service of old people resident in the nursing home. The research design was the research study to identify the degree of nursing serivce of old people. This study was conducted for 175 old people resident in 4 the nursing home for the elderly in Kangwon, Kyoggi and Kyungbuk provinces and Seoul, able to have the interview with the cognitive ability and understand the purpose of this study and agree to participate in this study. The questionnaire was composed of the following: 16 items relating to the general characteristics; 6 items relating to the physical function; 8 items relating to the daily activity ability; 22 items relating to the cognitive function; one item relating to subjective vision; one item relating to subjective hearing; 71 items relating to the classification of nursing service areas; 71 items relating to the degree of service demand; and 71 items relating to the level of service satisfaction. The contents of the questionnaire were composed by referring to the Psychiatric Nursing Assessment Protocol(Abraham, 1989; Abraham et al,. 1990) and the measurement instrument used by Lee, Kwang-ok. In data collection, research assistants were educated to concerning the structured questionnaire for one day and trained to conduct the interview for the questionnaire research in person. After full discussion over the questionable contents, 175 old people with the cognitive ability were randomly sampled from one ‘cost’ nursing home for the elderly in Seoul, one paid nursing home in Kyonngi Province, one free-charging nursing home in Kangwon Province and each of free-charging, cost and paid nursing homes in Kyungbuk Province. The trained research assistants conducted the questionnaire research through the direct interview. As to the questionable contents, accuracy was confirmed about the questionnaire by having the communication through the personal visit and telephone call with the researcher as needed. In data analysis, data were analyzed using the SAS statistical program after the process of coding. Data concerning the general characteristics of the old people in the nursing home analyzed on the basis of frequency and percentage. And mean and standard deviation were determined concerning the degree of demand for nursing service and Pearson correlation coefficient was used to determine the correlation between principal variables. The degree of demand for nursing service among the old people in the nursing home was shown as follows: The items relating to direct nursing services showed the high average score in venous injection(2.00, rectal injection(2.2), physical treatment(2.5) cold-warm therapy(2.0), vitality symptom measurement(2.1). The items relating to supportive nursing service demonstrated the following high average scores: education for health promotion(2.2); nutritional education(2.2); drug abuse and disuse education(2.5); informing all kinds of equipment and their usage(2.0); asking and counseling with the doctor(2.2); treatment and management plan(2.2); counseling with patients and heir guardian(2.2); assistance in money management(2.1); counseling on the health status92.3); tooth brushing(2.2); shampooing(2.2); bathing(2.4); sitz bath(2.0); assistance in shopping(2.1); recreation(2.1); conversational partner(2.5), emotional support(2.3), assistance in going to hospital(2.3), listening to the family problem(2.0); assistance in clothing and food life(2.2) and referral to the other medical institutions(2.2); Safety and environmental management(2.0) and contagion management(2.0) and the like. The old people showed the high level of demand for nursing services in many items relating to supportive nursing services as well as direct nursing services.

김미애,유소영,김화숙,국중기,임성훈,윤영주,김광원 대한치과교정학회 2005 대한치과교정학회지 Vol.35 No.1

본 연구는 교정환자의 브라켓과 치아 경계부 및 브라켓으로부터 2 mm 이상 떨어진 치아 평활면의 치면세근막에 존재하는 mutaus streptococci의 종 및 생물형에 차이가 있는지를 알아보고자 시행되었다. 조선대학교 치과병원에 내원한 13세 이상 35세 미만의 환자 28명으로부터 브라켓을 장착하고 있는 61개 치아에서 치균세균막을 채취하여 mutans streptococci를 MSB 배지에서 선택적으로 분리한 다음, 이들의 지놈 DNA를 추출하여 dextranase 유전자를 표적으로 하는 중합효소연쇄반응법을 시행하고, 그 증폭물을 Hae Ⅲ로 소화하고, 이를 전기영동하여 제한효소절편길이에 따라 그 종을 식별하였다. 또한 생물형을 조사하기 위하여 생화학적 검사를 실시하였다. 그 결과 브라켓과 치아 경계부 및 브라켓으로부터 2 mm 이상 떨어진 평활면의 치면세균막에 존재하는 mutans streptococci 종은 서로 비슷한 검출 빈도를 보이나 두 곳에 존재하는 mutans streptococci 생물형은 서로 차이가 있는 것으로 나타났다. 향후 브라켓과 치아 경계부 및 치아 평활면의 치면세균막의 mutans streptococci 생물형의 차이와 브라켓 주위의 법랑질 탈회 및 치아우식증 발병과의 상관관계에 대한 연구가 필요하다. The aim of this study was to compare the species and biotypes of mutans streptococci isolated from dental plaques sampled from the interfaces between the bracket and tooth surface and smooth tooth surfaces in orthodontic patients. Dental plaque was collected from the interfaces between brackets and teeth (test group), and from smooth tooth surfaces distant from brackets by more than 2 mm (control group). The dental plaque collected by a sterilized curette was transferred into a vial of 1 X PBS. The sample in the vial was vigorously vortexed for1 min and plated on mitissalivarius bacitracin (MSB) agar plate using cotton tips. The agar plates were incubated at 37℃ in a candle jar for 2 days, and again incubated for 1 more day at anambient temperature. Individual colonies were cultured in TH broth at 37℃ CO₂ incubator. The PCR-RFLP based on dextranase gene was performed for the identification of mutans streptococci at the species-level. For biotyping of mutans streptococci, biochemical tests were performed. There was no significant difference of the species of mutans streptococci isolated from both test and control groups. However, the biotypes of the mutans streptococci isolated from test and control groups were different. These results may offer the basic data to verify the relationship between the mutans streptococci biotype and enamel decalcification or dental caries in orthodontic patients with fixed appliances.

This paper presents a system for internetworking between different network management protocols. The internetworking system between SNMP(Simple Network Management Protocol) and CMIP(Common Management Information Protocol) has been designed. SNMP has been used as a standard protocol in Internet while CMIP has been selected as management protocol in OSI network. This approach is different from previous researches which convert protocols between management protocols. We have newly defined manage objects structure. Thus, even if a new management protocol would be introduce in addition, the new gateway system needs not be designed. We can achieve it through minimum modification in the interface of the managed objects. So, we can support managed objects defined previously using MOVI(Manage Object View Interface) concept presented in our previous research. Through this research, we have some additional benefits: it is able to internetwork between more complicated network management protocols, to increase usefulness of SNMP and CMIP, also it will use in internetworking between new network management protocols.

This study was carried out to evaluate the status of the groundwater quality for paddy fields irrigation in Korea. Water samples were collected at 130 sites throughout the country. Samples were collected at three seasons-April, July and October-in 2000. According to our survey, the groundwater was found to be suitable for irrigation purpose. Average EC was shown 0.286 dS/m. Nitrate-nitrogen and Cl^(-) concentration was 5.6 ㎎/L, 32.95 ㎎/L which satisfied the Korean Standards for Irrigation Water. Nitrate-nitrogen concentration in each province was shown as following orders: Jeju (11.17 ㎎/L) > Chungnam (8.16 ㎎/L) > Gyeongbuk (6.64 ㎎/L) > Gyounggi (5.91 ㎎/L) > Chungnam (4.95 ㎎/L) > Gyeongnam (3.91 mgk) > Jeonbuk (3.50 ㎎/L) > Jeonnam (3.27 ㎎/L) > Gangwon (2.91 ㎎/L). The concentration by sampling seasons were October (6.62 ㎎/L) > July (5.88 mg&) > April (4.78㎎/L). As the soil of Jeju Province is usually derived from volcanic ash soils mainly used for upland drops, it may influence the nitrate-nitrogen concentration of groundwater. The amount of rainfall also influence the water quality. But the COD_(Cr), were shown April (3.17㎎/L) > July (2.91 ㎎/L) > October (2.40 ㎎/L), it is highly related in the basal dose of organic matter fertilizers. This study demonstrated that groundwater quality was suitable for irrigation, but continuous monitoring is recommended for agricultural policy and developing OECD agricultural environment indicators.
