In this study, the 4th (1997) and 6th (2013) direct measurements of Size Korea compared the changing shape of women between the ages of 12 and 18. Comparing the items of height and length, the height and shoulder height were significantly reduced, the waist height was not significantly different, and the height of the upper hip was significantly increased, resulting in a smaller upper torso ratio and a higher lower torso rate. The width and thickness associated with human obesity, the circumference items and obesity levels often increased significantly with the change of the times, indicating that the overall body size was increased and that the chest area was changed to a cylindrical shape with changes in the breast equilibrium. Comparing agespecific measurements with graphs analyzing the trend of change in growth, the results showed that the change in 1997 was minimal since age 14; however, a continuous increase was achieved in 2013 that corresponded to the age at which growth is complete. The results of these studies are expected to be used as basic data to predict pattern design, body implementation, and trends in shape changes for young women.

Streptavidin (STR)과 Biotin system은 Biotin의 Streptavidin에 대한 높은 비공유 친화력(non-covalent affinity; $K_D=10^{-14}M$)과 4 Biotin 결합부위를 갖는 Streptavidin의 tetramer 구조로 인해 복수의 항원결합부위 및 복수의 항원특이성을 갖는 항체를 제조할 수 있기 때문에 가장 활발하게 연구되고 있다. 이 system을 활용하기 위해 우리는 Streptomyces avidinii 염색체 DNA로부터 PCR을 통해 Streptavidin (STR) 유전자를 증폭하고 이를 TRAIL (tumor necrosis factor ${\alpha}$ related apoptosis induced ligand) receptor인 death receptor 4 (DR4)에 특이적으로 결합하는 hAY4 single-chain Fv 항체유전자에 융합시켰다. 대장균에서 발현시킨 STR에 융합된 hAY4 ScFv (hAY4-STR) 항체는 가열시킨 SDS-PAGE에서 43 kDa monomer를 나타내었다. 그러나 가열하지 않은 SDS-PAGE와 Size-exclusion chromatography에서는 tetramer인 172 kDa을 나타내었는데 이는 hAY4 ScFv-STR 항체가 STR의 자연적인 비공유결합에 의해 유도된 tetramer를 형성하고 있음을 나타내고 있다. 본 융합 단백질은 Ouchterlony assay와 ELISA에서 보여주는 것처럼 자연 Streptavidin과 유사한 Biotin 결합력을 유지하고 있었다. ELISA와 Westernblot을 이용하여 정제된 hAY4-STR 융합항체의 DR4 항원결합력 또한 확인하였다. 게다가 표면 플라즈몬 공명(surface plasmon resonance) 분석에서 hAY4 ScFv-STR tetramer는 tetramerization에 의해 hAY4 ScFv monomer보다 60배 더 높은 항원결합력을 나타내었다. 요약하면 hAY4 ScFv-STR 융합단백질은 E. coli에서 soluble tetramer로 성공적으로 발현 및 정제되었으며 Biotin과 DR4 항원에 동시에 결합함을 보여 주었다. 이는 bifunctional and tetrameric ScFv 항체를 제조 할 수 있음을 제시해 주고 있다. The Streptavidin and Biotin system has been studied most extensively as the high affinity non-covalent binding of Biotin to STR ($K_D=10^{-14}M$) and four Biotin binding sites in tetrameric Streptavidin makes this system useful for the production of multivalent antibody. For the application of this system, we cloned Streptavidin amplified from Streptomyces avidinii chromosome by PCR and fused to gene of hAY4 single-chain Fv antibody specific to death receptor 4 (DR4) which is a receptor for tumor necrosis factor ${\alpha}$ related apoptosis induced ligand. The hAY4 single-chain Fv antibody fused to Streptavidin expressed in Escherichia coli showed 43 kDa monomer in heated SDS-PAGE. However, this fusion protein shown in both non-heated SDS-PAGE and Size-exclusion chromatography exhibited 172 kDa as a tetramer suggesting that natural tetramerization of Streptavidin by non-covalent association induced hAY4 single-chain Fv tetramerization. This fusion protein retained a Biotin binding activity similar to natural Streptavidin as shown in Ouchterlony assay and ELISA. Death receptor 4 antigen binding activity of purified hAY4 single-chain Fv fused to Streptavidin was also confirmed by ELISA and Westernblot. In addition, surface plasmon resonance analysis showed 60-fold higher antigen binding affinity of the hAY4-STR than monomeric hAY4 ScFv due to tetramerization. In summary, hAY4 single-chain Fv fused to Streptavidin fusion protein was successfully expressed and purified as a soluble tetramer in E. coli and showed both Biotin and DR4 antigen binding activity suggesting possible production of bifunctional and tetrameric ScFv antibody.
CPTED 관점에서 본 공공청사의 현황 및 개선방안 연구
김서우(Seou Kim) 한국셉테드학회 2022 한국셉테드학회지 Vol.13 No.2
본 연구에서는 국가 및 지방정부의 공적인 업무를 수행하는 공공청사가 침입 등의 범죄예방 측면에서 안전한지, 또 빈번한 집회 및 시위로 인한 피해를 최소화할 수 있도록 계획되고 있는지를 확인하고 개선방안 도출하고자 하였다. 연구성과로서 첫째, 정부청사의 경우 2016년 12월에 「정부청사관리 규정 및 시행규칙」에 ‘청사의 출입 관리’ 및 ‘방호 진단’을 신설하였으나 지방 정부청사의 경우 아직 제도적으로 반영되지 못한 상태이다. 또한 여기에 반영된 내용은 「건축법」에 따른 아파트 등에 적용되는 범죄예방 건축기준에 한참 미치지 못하는 수준임을 확인할 수 있었다. 둘째, 공공청사를 대상으로 한 집회 및 시위가 증가하고 있고, 소음 등으로 인해 공공청사에서 업무수행에 어려움을 겪고 있는 것으로 설문조사 결과 분석되었다. 셋째, 공공청사가 범죄로부터 안전하기 위해서는 공공청사에도 「건축법」에 따른 범죄예방 설계 기준이 적용되어야 하며, 시위로 인한 업무의 피해를 최소화하기 위해서는 차음 성능이 강화된 창호 설치 등의 조치가 필요하다. The purpose of this study is to investigate government office buildings and the environmental factors that contribute to crime preventative designs of those buildings. It has been found that: first, in the case of central government buildings, “access management of government buildings” and “protection diagnosis” were newly established in the 「government building management regulations and enforcement regulations」 in December, 2016. However, this change has yet to be established in local government buildings. In addition, it was confirmed that the contents of regulations reflected here were far below par compared to the crime prevention building standards applied to personal apartments under the 「Building Act」. Second, as rallies and protests that take place near government office buildings increase every year, surveys confirm that exposure to noise has a negative impact on work performance. Finally, it is crucial that crime preventative designs should be strictly controlled by regulation (ex. building codes), so that civil servants are protected from crimes. It is necessary to improve sound insulation performance of windows to minimize the noise generated by protests to not hinder the work performance of civil servants. These findings help understand the current environmental conditions of government office buildings associated with crime prevention facilities. There is room for improvement in the principles and process to make the government office building better, safer and more pleasant for both citizens and officials.

Lymphadenopathy in the thoracic cavity is frequently caused by inflammatory diseases. In very rare cases, the node-bronchial fistula has been reported to be the cause of complications of pulmonary tuberculosis. A male patient with necrotizing pneumonia and mediastinal lymph node enlargements identified by chest computed tomography was also found to have a node-bronchial fistula caused by lung cancer. The patient was treated for tuberculosis with pneumonia for one week before a definitive diagnosis was made. A further investigation revealed him to have non-small cell lung cancer (NSCLC, adenocarcinoma) and multiple mediastinal lymphadenopathies accompanied with the node-bronchial fistula. We report this specific case that had been previously treated for tuberculosis but was later revealed to be NSCLC accompanied with a node-bronchial fistula.

We ensure a flat and regular basic surface by using part of joint waterproofing improved sheet method applying the upper slab of a concrete structure. We solve the problem of getting loose scale the general sheet by waterproofing of the sheet and improving adhesive strength of the basic concrete. Also, waterproofing sheet union to problem of joint have solved using of insertion type method so that, it improved a watertightness. It has improved in resist impact, resist abrasion and it is the effect of shortened construction period and cutting down on construction expenses. Here are the special quality and superiority of this waterproofing research. (1) Level material has the super adhesive strength so that it makes the basic surface without the gab of waterproofing sheet and waterproofing layer with the string adhesive strength. (2) We unite the sheet with the joining part between sheets by waterproofing sheet joint using of method. (3) There is the effect of shortened construction period and cutting down on construction expenses without waterproofing of protection.
