Impact of the oxygen functional group of nitric acid‑treated activated carbon on KOH activation reaction

Ji‑Hyun Kim,Sang Youp Hwang,Jung Eun Park,Gi Bbum Lee,Ho Kim,Seokhwi Kim,Bum Ui Hong 한국탄소학회 2019 Carbon Letters Vol.29 No.3

To prepare activated carbon with a high specific surface area, oxygen functional groups (OFGs) that can serve as useful electron donors during KOH activation were treated with nitric acid and incorporated into activated carbon. OFGs are incorporated differently according to the surface characteristics of starting materials. Up to 22.46% OFGs are incorporated into wood-based activated carbons (WACs), the C=O, COOH contents was 1.90, 17.05%, respectively. Whereas up to 12.82% OFGs are incorporated into coconut shell-based activated carbons, the C=O, COOH contents was 4.12, 6.15%, respectively. The OFGs used for increasing the specific surface area are the carbonyl group, and as the content of the functional group increases, the carbonyl group spreads to the carboxyl group. The specific surface area of activated carbons increased by 10–68% with an increase in the carbonyl group up to 6% (maximum point of carbonyl group). On the other hand, the specific surface area for WACs increased when the carboxyl group was 10% or below, but decreased by 6–15% when it increased to 10% or excess.

Objective: The aim of this study was to evaluate the volumes and areas of the upper airways in children with Class II malocclusion, using three dimensional cone-beam computed tomography (CBCT) and to compare the volumetric and cross-sectional measurements and cephalometric variables to investigate possible relationships between the upper airway and facial morphology. Methods: CBCT scans were obtained from 37 subjects (17 boys and 20 girls; average age, 11.02 years). The upper airway volumes and areas were measured, and compared with cephalometric variables. Results: The area of the PNS-posterior plane (SPP) was significantly smaller in the Class II malocclusion group (p < 0.05). Also, the volumetric and cross-sectional measurements were lower in Class II than in Class I malocclusion groups, although the differences were not significant between the two groups (p > 0.05). The Class II malocclusion group showed significantly smaller values of PFH, mandibular body length, pog to N perp and showed larger values of FMA, ANB, and facial convexity than the Class I malocclusion group. The volume of the upper airway in front of PNS point (WN) showed negative correlation with ANB (p < 0.05). Conclusions: The Class II malocclusion group had a narrower upper airway associated with a decreased posterior facial height and a divergent growth pattern than the Class I malocclusion group. 성장기 아동의 상기도 협착은 두개안면 성장에 영향을 미칠 수 있다. 본 연구는 3차원 cone-beam computed tomography (CBCT)를 이용하여 제II급 부정교합 아동의 상기도 부피 및 단면적 계측치와 측모두부계측치를 비교하여 상기도와 안면 형태와의 연관성을 알아보고자 하였다. 37명의 아동(남자 17명, 여자 20명, 평균 연령 11.02세)의 CBCT를 촬영하였다. 연구 결과, 상기도의 PNS-posterior plane에서의 단면적(S_(PP))은 제II급 부정교합군에서 유의하게 작았다 (p < 0.05). 상기도 부피 계측치는 제II급 부정교합군에서 제I급 부정교합군보다 작았으나, 두 군 간 통계적으로 유의한 차이는 없었다. 제II급 부정교합군은 후안모고경(PFH), mandibular body length (p < 0.05), Pog to N perp (p < 0.01)에서 제I급 부정교합군보다 유의하게 작은 값을 보였고, FMA (p < 0.05), ANB, facial convexity (p < 0.01)는 유의하게 큰 값을 보였다. 제II급 부정교합군의 PNS 전방의 상기도 부피(W_(N))는 ANB difference 각도와 음의 상관관계를 보였다 (p < 0.05). 제II급 부정교합 아동은 상대적으로 좁은 상기도 부피를 가지며 이에 따른 감소된 후안모고경(PFH)과 하악골의 divergent한 안면 성장 양상을 보였다.

In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.

경상북도 영일만 연안에서 2001년 2월, 5월, 8월 및 11월에 계절별로 채집된 부유성 난과 자치어의 종조성 및 계절변화를 연구하였다. 채집된 부유성 난은 총 9개 분류군으로, 멸치가 출현량의 63.4%로 가장 우점하였고, 다음 까나리는 23.7%를 차지하였으며, 나머지는 7개 분류군이 12.9%를 차지하였다. 자치어는 총 7목 28과 37개의 분류군이 출현하였는데, 그 중 32개 분류군은 종 수준까지, 3개 분류군은 속 수준까지, 2개 분류군은 과 수준까지 동정하였다. 2월에는 2목 7과 12종, 5월에는 3목 5과 7종, 8월에는 6목 18과 21종, 11월에는 6목 14과 16종이 출현하였다. 주요 출현종으로서는 까나리가 자치어 출현량의 22.7%를 차지하여 가장 우점하였으며, 다음은 멸치가 16.7%, 동갈양태속 어류가 14.1%를 차지하였고, 노래미와 쥐노래미가 각각 5.7%와 5.5를 차지하였다. The ichthyoplanktons in coastal waters of Yongil Bay were sampled during four different months (February, May, August and November 2001) to study their distribution. The collected fish eggs were identified as belonging to nine species. The most dominant species Engraulis japonicus accounted for 63.4% of the total fish eggs, followed by Ammodytes personatus (23.7%) and Sardinops melanostictus (9.2%). The collected larvae and juveniles were identified into 37 taxa (28 families, 7 orders). Of these, 32 were identified to species, three were identified to genus and two were identified to family level. The dominant species Ammodytes personatus accounted for 22.7% of the total larvae and juveniles, followed by Engraulis japonicus (16.7%), and Repomucenus sp. (14.1%). These three taxa constituted 53.5% of the total collected larvae and juveniles.

Objective: Occupational medicine specialists in the Busan, Ulsan and Kyung-Nam areas established an area-based occupational disease surveillance system and used this system to collected case information for the purpose of preventing occupational diseases Methods: l l hospital participated in this system. The authors selected five main diseases, which were hand-arm vibration syndrome (HAVS), work-related musculoskeletal disorder (WRMSD), occupational asthma, occupational skin disease and occupational and occupational lung cancer and established their case definitions. All cases were reported on the web, and real time analysis was conducted. Results: Between April 2001 and April 2003, 192 cases of HAVS, 118 cases of WRMSD, 33 cases of occupational asthma, 17 cases of occupational skin disease and 17 cases of occupational lung cancer (for a total of 377 cases of these five main diseases) were reported. most of the HAVS cases came from shipbuilding, and 172 of them (92.7%) were associated with grinding. Of the four main types of WRMSD, carpal tunnel syndrome (CTS) was the most prevalent with 46 cases and shipbuilding was also the main industry involved (83.9%). The ergonomic risk factors involved mainly associated with the hand. In 19 (57.6%) and 4 (12.1%) cases of occupational asthma, the agents involved. The causative agents of occupational lung cancer included Cr, welding fume, PAH, Ni, etc. 10(58.8%) of the cases were diagnosed as squamous cell carcinoma and 5(29.4%) as adenoma. Conclusion: This result showed that an area-based occupational disease surveillance system might provide an effective method of evaluating the prevalence of such diseases, however the Busan, Ulsan and Kyung-Nam provinces are too large to be treated as individual areas. Therefore, the authors suggest that each province should establish its own surveillance system.

중국 기업공시제도의 개선방향에 관한 연구

홍기용,박희선 한국세무회계학회 2002 세무회계연구 Vol.11 No.-

중국은 1980년대에 증권시장이 형성된 후 상장회사의 운영이 더욱 확대되었으며, 그동안 증권법을 제정하였고 관련법규들도 개정을 하는 등 각종 제도를 정비해 왔다. 이 과정에서 기업정보의 공시도 많은 발전을 가져왔지만 아직도 공시제도의 운영이나 관리가 선진국가들에 비해 미흡한 수준이다. 최근 중국은 시장경제의 발전 특히 WTO의 가입으로 국제경쟁력강화와 국제관례에 부합되도록 기존의 회계 및 경제법규들을 점진적으로 개정하여 가고 있다. 그러나 효율적 증권시장의 운영과 투자자 권익을 보호하기 위한 현행 기업공시제도에 대한 개정은 개정의 폭이나 내용의 중요성 측면에서 볼 때 부분개정의 형식에 의한 것으로서 증권법체계가 완전히 정비되지는 못하였다고 할 수 있다. 따라서 이 논문은 문헌연구를 통하여 현행 중국의 기업공시제도 문제점을 검토 및 분석하고 향후 개선방향을 아래와 같이 제시하였다. 첫째, 정부주도의 공시관리체제를 민간관리체제로 이양, 둘째, 전자매체공시의 보편화를 추진, 셋째, 공시되는 정보의 정확성을 제고, 넷째, 회계정보의 다양성 및 적시성을 확보, 다섯째, 공시책임자제도의 도입 등이다.

Mirtazapine 사용과 연관된 고혈당증 환자 1례

홍영재,박지도,김정기 대한신경정신의학회 2001 신경정신의학 Vol.40 No.1

Mirtazapine은 고전적 우울증 치료제의 부작용과 독성을 감소시키기 위한 시도로 개발된 여러 가지 약제들 중 하나로 α2-noradrenergic 자가수용체와 이종수용체에 대한 길항작용을 함으로써 norep-inephrine과 serotonin의 신경전달을 항진시켜 항우울 효과를 나타내며 흔히 진정, 체중증가, 현기증등의 부작용을 나타내는 것으로 알려져 있다. 저자들은 Mirtazapine 사용과 연관되어 고혈당증이 발생하였다가 약물투여 중지이후 혈당이 정상으로 회복된 1례를 경험하였기에 보고하는 바이다. 향후 고혈당증이나 당뇨병을 일으킬 수 있는 약물을 투여하는 환자에서는 당뇨병에 대한 전반적인 검사 및 약물투여 기간 동안에 혈당에 대한 주의 깊은 추적검사가 시행되어져야 할 것으로 생각한다. Mirtazapine- a newly developed drug with reduce adverse effects and toxicity of original antidepressants- has been known to have antidepressant dffect by enhancing the transmission of norepinephrine and serotonin via blockade of α₂-noradrenergic autoreceptor and heteroreceptor and to have common side effects such as sedation, weight gain, and dizziness. We report a case of 50 years old female depressive patient who developed mirtazapine-associated hyperglycemia during treatment with mirtazapine and returned to normal glucose level after stopping the usage of mirtazapine. In patients who receive drugs with the risk of hypergly cemia and diabetes mellitus, we should consider the evaluation for diabetes mellitus and follow it up carefully in the future.
