Mu-Geun Kim,Dam-Yong Park,Joon-Jo Moon,Hyunsu Kim 한국조류학회II 2016 한국조류학회지 Vol.23 No.2

The Western Seoul Lake Park which lies in Yangcheon Sinwol-dong of Seoul was opened in October 2009. The number and species of birds are expected to continue to increase in the future around the airspace over the Western Seoul Lake Park. The Western Seoul Lake Park is, however, geographically close to the southern end of the Gimpo Airport, and it is located on the approach surface of the obstacle limitation surfaces thereof. For that reason, the probability of bird strikes around the airspace over the Western Seoul Lake Park would be significantly high in comparison with that of bird strikes around the airspace over the other parks near the Gimpo Airport. To assessment of bird strike risk in the Western Seoul Lake Park, we visited four times between 2015 and 2016. And ducks and geese were identified as the most dangerous species. In this paper, we will, through the analysis of the Western Seoul Lake Park case, propose a new approach to bird strike risk management around that Park and also present the improvements of current relevant policies.

This study aims at revealing the physiological responses of dehydration (DH) and rehydration (RH) in intermittent exercises at the work intensity of 70% HR max. First, with general student public, three times of exercise (each for 20 minutes) at the given work intensity were taken, with a break for 25 minutes respectively. Their heart rate, rectal temperature and plasma electrolyte concentration both DH and RH were measured. Second, in two groups of athletes and non-athletes, 9 rounds of exercise (for 100 minutes) and 8 breaks (for 60 minutes) were taken, with RH forced 10 times to compensate for the subjects' water loss. Their change in sweat loss and plasma electrolyte concentration as well as the IVDP(Intensive Voluntary dehydration Phenomenon) were experimented. The summary of this research follows. 1) Mean heart rate and rectal temperature in intermittent exercises were higher at DH than at RH, growing up at the increasing level of DH. 2) RH saw no change in the plasma concentration of Na+, K+ and Cl-, while DH observed a significant increase. 3) HCO₃made a significant decrease at DH before growing up. 4) Mg++ had no change, while Ca++ increased significantly at RH and DH. 5) Lactate showed an increase with significance at RH and DH, especially greater at DH. 6) Osmotic pressure increased meaningfully at DH. 7) Anion gap increased significantly at DH and RH. 8) On the other hand, when the forced RH was held, the group of athletes had greater sweat loss per body surface area than that of non-athletes. 9) The athletes' plasma concentration of Na+ and Cl- revealed a clear decrease. 10) There was seen no significant change in the plasma concentration of K+, Mg++ and Ca++ in both groups. 11) The IVDP occurred at the RH of 2.3ℓfor athletes and more than 2.5ℓfor no-athletes.

이재형,강준구,박준성,이창범,박용수,김동선,함준수,김태화,안유헌,박충기 대한당뇨병학회 2002 임상당뇨병 Vol.3 No.2

가성 장폐색은 기계적인 폐색부위가 없이 복부팽만과 구토 등 장폐색의 증상과 징후가 나타나는 질환을 말하며, 선행원인을 찾을 수 없는 원발성 가성 장폐색과 다른 질환에 이차적으로 발생하는 속발성 가성 장폐색으로 나눌 수 있다. 당뇨병은 잘 알려진 속발성 가성 장폐색의 원인이지만 실제로 당뇨병에 의한 가상 장폐색의 발생 빈도는 매우 드문 것으로 보이며, 가성 장폐색의 적절한 치료에 대해서는 아직 논란이 있다. 저자들은 2형 당뇨병 환자에게 대장에 국한된 급성 가성 장폐색을 진단하고 보존적 치료를 시행하여 호전된 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Colonic pseudo-obstruction is a disorder characterized by gross dilatation of the colon in the absence of any anatomic lesions, which obstructs the flow of the intestinal contents. Diabetes is a well known cause of secondary pseudo-obstruction but its prevalence in rare and not well understood. A 59-year-old woman patient was admitted due to abdominal distension and nausea of a day's duration. She was diagnosed with diabetes 15 years ago, but the condition had been poorly controoled. On the abdominal radiographs, there were marked small and large bowel dilatation with the, exception of the descending colon. Our initial diagnosis was mechanical obstruction, but the possible causes were not found. Also, we could not find another cause of the secondary pseudo-obstruction, with the exception of diabetes mellitus. Thus, she was diagnosed with a diabetes induced intestinal pseudo-obstruction. The colonic dilatation was resolved by conservative management and she became comfortable in 10 hospital days, and was subsequently discharged.

This study was planned to provide basic data for activating quality improvement by genera hospital with more than 400 beds across the country, of which 65 coordinators answered. Main results of the study are as follows.. 1. Job satisfaction and organizational commitment by individual characteristics were compared. It was revealed that the sense of self-efficacy was related to job satisfaction positively. But job satisfaction and organizational commitment by locus of control showed no significant difference. 2. In terms of the characteristics of QI activities, the active participation of QI coordinators in QI planning process and smooth communication among hospital staffs were showed positive relationship to job satisfaction significantly. 3. Also support system was proposed as most significant variable related to the job satisfaction and the organizational commitment of QI coordinators. Especially support, to Ql activities by CEO's, seniors, and other hospital staff was a factor to enhance the job satisfaction and organizational commitment of QI coordinators. 4. In the aspect of organizational culture, culture which were tendency to be recognized high autonomy in their work and organizational identity strongly and to operate reasonable compensation system were related to job satisfaction and organizational commitment positively. The more formalized climate, supportive communication, cooperative teamwork and promoting creative/ risk take behavior, it showed the higher organizational commitment. 5. For the aspect of QI job characteristics, QI coordinators' job satisfaction was high when QI office was arranged for independent department which was exclusively in charge of QI activities and their role is exclusively in charge of QI. It can be concluded that organizational support in the aspect of relation and finance and efforts of encouraging their motivation and providing on the job training program are need

티타늄 상에 강유전성 barium titanate 박막 형성과 분극처리에 의한 유사체액 내에서의 calcium phosphate 생성 증진

박영준,이용렬,황규석,김은주,임용무,이기헌 대한치과기재학회 2001 대한치과재료학회지 Vol.28 No.2

This study was performed to fabricate a ferroelectric barium titanate (BaTiO₃, BTO) thin film on Ti substrate and to evaluate the effect of poling treatment for the improvement of calcium phosphate (Ca-P) formation. BTO thin-film was spin-coated on Ti substrate by dipping-pyrolysis technique using coating sol obtained by mixing Ba-naphthenate and Ti-naphthenate as starting substances. Pre-heating temperature of the BTO thin film was performed at 500℃ because organic-solvent was completely volatilized without any crystal growth, and the final heat treatment was performed at 600, 650, 700, 750, 800, 850℃, respectively. By repeating the coating and pre-heating procedure gor 20 times, homogeneous thin film of 0.7㎛ thickness could be fabricated, and it performed well during the poling treatment without breakdown. The final heating treatment of the BTO thin film at 750℃ produced a homogeneous crystalline structure without heterogeneous TiO₂formation, which was confirmed by field emission scanning electron microscope (FE-SEM) and X-ray diffraction analyser (XRD). An average grain size of 20∼30 ㎚ were confirmed by SEM observation. The final heat-treated BTO thin-films were polarized (Ep = 5 V/㎛) from 160℃ to 25℃ in heating chamber for 2 h. The negatively poled BTO thin film (N-BTO), non-poled BTO thin film (BTO), Ti substrate (Ti), and 600℃ heat-treated Ti (Ti-O) were immersed in SBF and Eagle's MEM solution for 15 days at 37℃. After the immersion period, the morphological and compositional changes of the surfaces were investigated using a FE-SEM and an energy dispersive X-ray spectrometer (EDX). After immersion in simulated body fluid (SBF), sodium chloride (Nacl) crystals were formed on Ti, Ti-O, and BTO surfaces due to anion adsorption (Cl), while Ca-P crystals were formed on N-BTO surfaces. We assumed that rapidly adsorded cations (Ca²□ ions) on the negatively charged surface at the initial stage acted as nuclei for the formation of Ca-P crystals. In MEM, sodium chloride (NaCl) was formed on Ti, and Ca-P layer including NaCl was formed on Ti-O. Weak and sparse Ca-P layers were formed on BTO, while thick, homogeneous, and dense Ca-P layer was formed on N-BTO, which was confirmed by FE-SEM and EDX. These results demonstrated that introducing a N-BTO on Ti is an effective method for the improvement of Ca-P formation in SBF and MEM. In conclusion, negatively charged ferroelectric BTO thin-film on Ti would improve the possibility of implant osseointegration.

양극산화와 열산화 처리로 형성된 티타늄 산화막의 표면 특성과 생체활성에 관한 연구

The purpose of this study was to evaluate the surface characteristics of titanium oxide films formed by anodization and thermal oxidation techniques, and to investigate its effects on formation of calcium phosphate. As experimental specimen groups, naturally oxidized film (AS-R), thin anodic oxidation film (ANO-L), thick anodic oxidation film (ANO-H) treated up to dielectric breakdown voltage, and thermal oxidation films of TH-L and TH-H treated at 530℃ and 800℃ in the air, respectively, were prepared. Surface characterization was performed using field emission-scanning electron microscopy (FE-SEM), X-ray diffractometry (XRD), Raman spectroscopy, and X-ray photoelectron spectroscopy (XPS) in order to evaluate the micro-morphology, crystalline structure, chemical composition, and binding structure of the oxide films. Bioactivity of specimen groups was investigated by evaluating the degree of calcium phosphate formation after immersing the samples in MEM for 7 days. The results were as follows: 1. Nanometer sized granular oxide particles were distributed on the surface of TH-L samples and sub-micrometer sized large crystallites were formed on TH-H samples. Irregularly shaped oxides were observed in ANO-L, and homogeneously porous oxide film having average pore size of about 0.5 ㎛ was formed in ANO-H. 2. Titanium oxide films having anatase crystalline structure were formed on ANO-L and TH-L sample surfaces. However, the preferred orientation crystal planes of ANO-L and TH-L were different to be (101) and (004) plane, respectively. Rutile crystalline structure was dominantly shown on TH-H sample, and anatase and rutile crystals were co-existed on ANO-H sample surfaces. 3. The amounts of hydroxyl group, which is related to the bioactivity of titanium implant, were higher in thermally treated specimen groups than in other groups. This result was analyzed to have close relation to the preferred orientation crystal plane and surface area of oxide films. The content of hydroxyl group increased as the density of surface titanium atoms increased, and that was least in specimen group having rutile and anatase crystalline structure in coexistence. 4. Immersion test in MEM showed that the capacity of calcium phosphate formation was dependent on total content of hydroxyl group and surface morphology of titanium oxides.

Objective : There were variant results for correlation between the postoperative cure rate and valsalva leak point pressure (VLPP) for female stress urinary incontinence (SUI). Therefore the aim of this study was to assess the influence of VLPP on the outcome of suprapubic arch (SPARC) procedure. Materials and Methods : A retrospective analysis was made of 246 women who underwent SPARC procedure for SUI. Based on VLPP, the patients were divided into 2 groups: group A (VLPP<60cmH2O) and group B (VLPP≥60cmH2O). The objective success rate and subjective success rate were assessed. Before surgery, the patients were evaluated with history taking, physical examination, urinalysis and urodynamic studies. The objective success rate was evaluated by clinical examination and the 1-hour pad test postoperatively and the subjective satisfaction rate was assessed using questionnaires for the patients' satisfaction and evaluated by recommendation rates of SPARC procedure to other patients. The objective success rate included cure and improvement, the subjective success rate included satisfaction and fair. Results : The number of patients in each group was 145 patients (group A) and 101 patients (group B). The objective success rate was 99.3% (group A) vs 98.0% (group B) (p=0.285). The subjective success rate was 98.6% (groupA) vs 98.0% (group B) (p=0.500). Recommendation rates of SPARC procedure was 94.5% (group A) vs 95.0% (group B) (p=0.422). Conclusion : It is our belief that SPARC procedure for female SUI is efficacious and safe regardless of preoperative VLPP.
