A pilot scale SBR (working volume, 20㎥) treating piggery wastewater was operated with real wastewater. The operation mode of intermittent feeding of raw water and sub-cycle with repeating anoxic-aeration conditions were adapted to avoid the high-strength nitrogen inhibition. In sub-cycle, aeration time for nitrification was tried to be controled with ORP and/or DO meter. The characteristics of control was somewhat different between ORP and DO. DO showed potential ability to detect complete ammonia oxidation point by the first order differential values or absolute value. Especially, DO was proved to be useful for high loading rates. ORP indicated the ending point of nitrification by the plateau appearing after bending point. Because ORP can be utilized as a diagnosis tool by its good sensitivity for the microbial condition in reactor, the simultaneous application of DO and ORP was recommended for the stable control of SBR.

This study was conducted in order to explore general flora of the Gyounggi-do Province and to clarify the distribution of some specificated taxa of the Korea. Daebu-do Island, Mt. Taewha, Mt. Hwaya, Mt. Gumdan, Mt. Chilhyun and Mt. Chulma among eighth grade-area of the Degree of Green Naturality (DGN) within the boundary of the Gyounggi-do Province were visited to investigate local flora. The number of identified vascular plant species were as follow; Mt. Hwaya: 120 species (99 genera of 67 families), Mt. Teawha: 132 species (103 genera of 56 families), Daebu-do Island: 124 species (103 genera of 50 families), Mt. Chulma: 129 species (99 genera of 67 families), Mt. Gumdan: 121 species (96 genera of 52 families), Mt. Chilyun: 90 species (74 genera of 42 families). The endemic Clematis brachyura Maxim. was found to distribute Daeby-do. It seemed that plantation was occupying large area in forest of the Gyounggi-do Province. Forty two specificated taxa were identified and 3 taxa, 10 taxa, 5 taxa, and 24 taxa were sorted into forth grade, third grade, second grade, and first grade respectively. Mt. Taewha showed the highest record (16 taxa) in the number of specificated taxa, Mt. Hwaya was the next with 13 taxa. Mt, Chulma (12 taxa), Mt. Gumdan (11 taxa), Daebu-do Island (7 taxi), and Mt, Chylma (4 taxi) followed. Mt. Taewa and Mt. Whaya were found to be relatively higher in the score calculated front the specificated taxa distribution, while Daebu-do Island and Mt. Chilyun were lower, that difference was probably due in part to consequences of severe disturbance of human activities. With respect to the consequences of severe disturbance of human activities. With respect to the geographical proximity to the Gangwon Province, Mt. Hwaya showed higher similarity of the species composition to that of the Mt. Jumbong.

Jin, Long-Hu,Shin, Hwa-Yoan,Yoon, Seung-Hwan,Seong, Do-Hwan,Park, Chang-Shin,Lee, Tack,Yoon, Sang-Min Korean Continence Society 2011 International Neurourology Journal Vol.15 No.1

<P><B>Purpose</B></P><P>To compare the physical characteristics of detrusor overactivity (DO) induced by intravesical infusion of saline in awake, sham rats and rats with chronic spinal cord injury (SCI), by simultaneous registrations of intravesical and intraabdominal pressures.</P><P><B>Methods</B></P><P>Male Sprague-Dawley rats, normal or with a spinal vascular clip at the level of Th9, were investigated cystometrically 1 and 4 weeks after SCI. Intravesical pressure (IVP) and intraabdominal pressure (IAP) were recorded simultaneously to evaluate true DO. During the filling phase, the event of IVP rises, defined as increments that exceeded 2 cmH<SUB>2</SUB>O from baseline, were determined as DO according to the absence of simultaneous changes in IAP.</P><P><B>Results</B></P><P>All SCI rats exhibited DO during the filling phase, which was not shown in sham rats. The frequency and pressure of DO had a tendency to decrease with time. The DO frequency of SCI rats after 4 weeks (0.9±0.2 min<SUP>-1</SUP>) was decreased compared with that after 1 week (2.1±0.4 min<SUP>-1</SUP>; P<0.05). The DO pressure of SCI rats after 4 weeks (8.4±1.9 cmH<SUB>2</SUB>O) was decreased compared with that after 1 week (11.6±2.9 cmH<SUB>2</SUB>O; P>0.05).</P><P><B>Conclusions</B></P><P>Cystometric studies in awake male SCI rats showed some significant changes in bladder function after SCI. All SCI rats exhibited DO during the filling phase, and showed different physical characteristics of DO over the course of time. The neurological basis of these time-related changes remains poorly understood, but may provide important prognostic information about long-term urological management in SCI patients.</P>

This study was conducted to investigate knowledge required, quality of life and social support after breast cancer surgery. Subjects of this study were postoperative female breast cancer patients (n=95). Questionnaire was conducted with 4 parts, general characteristics, knowledge required, , quality of life after surgery and social support from 3 groups (family, friend and community). The survey was conducted by individual interview. The percentage of premenopausal women was 69.5%(n=66) of total subjects. Results from cancer information need survey, ‘range of usual life after operation’ showed the highest mean score among items (4.32±0.49) and ‘diet information after operation’ showed the second highest mean score (4.25±0.47). Among items about quality of life after surgery, "I lost my pride on my usual life" showed the highest mean score (4.38±0.60). Among support from 3 groups, support from family showed the highest group in all items. We suggested that the systematic support program for Korean breast cancer patients is needed and that should be included family support and information of dietary therapy.

Government is the source of vast amounts of information. But, most information created or collected by the government is not routinely disseminated to the public. However, with the passage of the Freedom of Information Act, from 1!398, the public can access to government information, and the people' right-to-know will be secured. Thus, the purpose of this study is, first, to examine the important feature of the Freedom of Information Act and its influence to local autonomy, and second, to provide the desirable direction for its operation. This study suggests that, first, the Act should be well organized and institutionalized, and second, willingness of the public officials' be strengthened, and third, there should be a to disclose government information strong support from the executive.

하악전돌증의 악교정수술 후 연조직 형태변화에 대한 연구

성상진,박현도,김재승,문윤식 대한치과교정학회 2000 대한치과교정학회지 Vol.30 No.3

악교정수술에 관한 치료계획은 치료결과에 관한 정확한 예측을 바탕으로 수립되는 것이 바람직하며 이는 심미적인 결과를 얻기 위한 가장 중요한 요소 중에 하나이다. 성인에서 골격성 하악전돌증의 치료는 하악골후퇴술을 이용한 악교정수술법이 주로 이용되는데, 술후 턱끝의 돌출도가 과도하게 감소되어 하악전진이부성형술을 추가로 시행해야 하는 경우 하악골과 턱 부위의 연조직 변화방향이 상이하게 나타나므로 술후 연조직 변화를 정확히 예측하는데 한계가 있다. 본 연구에서는 골격성 하악전돌증을 주소로 악교정수술을 시행한 성인을 대상으로, 상행지시상분할골절단술(BSSRO)만을 시행한 경우(A군) 11명과 하악전진이부성형술(advancement genioplasty)도 같이 시행한 경우(B군) 9명의 경조직과 연조직 변화의 상관관계를 알아보기 위하여, 수술 8개월 이후에 채득된 측모두부계측방사선사진을 비교하여 다음과 같은 결과를 얻었다. 1. E-line에 대하여 상순은 더 돌출되고 하순은 더 후퇴되어 입술의 형태가 개선되었으며,하악전진이부성형술을 병행한 경우 하순의 돌출도는 더 개선되었다. 2. 두 군 모두에서 상순은 후방이동하고 비순각은 증가하였다. 3. 술후 B점에 대한 연조직 POGs점의 변화율은 A군에서 84%, B군에서 66%로 나타났으며 두 군간에 통계적 유의성이 있었다. 4. 경조직과 계측점의 수직변화량은 A군에서 감소하였다. The treatment plan for orthognathic surgery must be based on accurate predictions, and this can be produced the most esthetic results. Treatment of prognathic mandible in adult is usually orthognathic surgery using mandible set back, but mandible with retruded chin point is needed additional chin augmentation. In this case, the directions between mandible and chin point are different therefore, the prediction of soft tissue reactions must be modified. In this study, we materialize the patients who was taken orthognathic surgery due to prognathic mandible, 11each(Group A) was taken only Bilateral Sagittal Sprit Ramus Osteotomy (BSSRO), 9each(Group B) was taken additional advancement genioplasty. The lateral cephalometric radiography taken 8 months later after orthognathic surgery by this patients were used. The results of this study were as follows : 1.The profile of lips was favorable after surgery due to upper lip to E-line became prominent and lower lip to E-line was retruded. 2.In both group, upper lip moved posteriorly and nasolabial angle was increased. 3.The ratio of the soft tissue profile change in POGs point to skeletal B point movement was 84% in group A and 66% in group B, and there was statistical significance between group A and group B. 4.Vertical movement of hard tissue points is decreased in group A.
