A Development of Assessment Model for Maintenance of Type R Fire Alarm System in the Building
Lee,Su-Kyung,Yoo,Sang-Bin,Nam,Yang-Won 한국화재소방학회 1997 한국화재소방학회 학술대회 논문집 Vol.1997 No.-
Type R fire alarm is required intelligent buildings and height buildings which was based on automatic system. But in Korea, maintenance of fire alarm system is very poor. In this study, we developed assessment model for the type R fire alarm system which was assessed by using 96 checklist items. The assessment model was tested through the actual 4 buildings with type R fire alarm system. It is shown that present model can be applied for the assessment of all buildings through the examination of the suitability of assessment model by actual assessment. Also, it was made easily fire manager to carry out checklist for type R fire alarm system in buildings.

After briefly reviewing the history of lexcoigraphy in modem Korea, Nam Kishim tackles many problems created by the general deficiency of current Korean monolingual dictionaries in phonological morphological and semantic points. For example, most Korean dictionaries do not treat such phonological changes as the shortening of the stem vowel ㅓ in 더운, the prenominal form of the adjective 덥다, whose stem vowel ㅓ is pronounced long. He also takes issue with the practice of Korean dictionaries of including all kinds of proper names on little reliable principles : a typical dictionary enters a 600m-high hill while excluding better-known mountains higher than that. Hong Chai-song concentrates on the often misguiding information on transitive / intransitive verbs in current dictionaries. For example, a representative dictionary designates the verb 뛰다 simply as intransitive. But it is quite often used as an transitive also. In the sentence, 철수는 운동장을 뛰었다, 운동장 is the object of the transitive verb 뛰다. How could the compilers miss such an obvious fact? Hong suggests that they may have not been interested in being grammatically informative. A historical survey of the Oxford English Dictionary(OED) is given by Lee Sang-sup, with special emphasis on the vast amount of quotations from real sources contributed by thousands of volunteer readers through several decades and on its unwavering historical principle. A comparison between the OED's definition of Kimchi and a Korean dictionary's 김치 is given, showing the difference of principle in treating the same lexical item. Ahn Sam-huan presents a detailed account of Grimm's Deutsches Wo¨rterbuch which took generations of German lexicographers 133 years from its inception to its completion in 1971. On the basis of his study, Ahn suggests that future dictionary makers should cooperate as a group on a long-range comprehensive project. A moltivolume dictionary is an all-important cultural event for the whole nation, not to be influenced by private commercial interests. Choi Young-ai's survey of Chinese lexicography highlights the now on-going publication of 漢語字典 and 漢語詞典, admirable results of the cooperative effort of hundreds of Chinese scholars, a modus operandi for the Yonsei University graze to adopt in planning a new dictionary of the Korean language.

In this paper we have reconstructed an armillary sphere based on the Method of an Armillary Sphere Making described in the Volume 1 of The Collection of Writings on the Scientific Instruments-Uigijipsol (儀器輯說, two volumes) edited in the 1850's by Nam Byong-Chul (南秉哲, 1817-1863) who was a famous Korean states-man-scientist. Nam achieved convenience and accuracy in the measurements of stellar positions in the manner of selective setting the equatorial, ecliptic and horizontal poles by adding a pole axis exchange ring called Jaigeukkwon (載極圈) between the Three Arrangers of Time and Four Displacements. We made use of 3-dimensional graphic software for modelling Nam's armillary sphere which consisted of five layers-eight rings. Results of simulation showed that the pole axis exchange ring functioned properly in setting the equatorial, ecliptic and horizontal coordinates simply by exchange of positions of specified holes on the ring. We ascertained that the invention of Jaigeukkwon solved inherent problems in the conventional Chinese armillary sphere in computation of real ecliptic coordinates. It was revealed that Nam Byong-Chul made great contributions in the East Asian history of armillary sphere making.

A combination of atezolizumab and bevacizumab is currently recommended for treating unresectable advanced-stage hepatocellular carcinoma (HCC), as it has demonstrated superior overall survival and progression-free survival compared to sorafenib. However, concerns have been raised regarding serious adverse events associated with bevacizumab, such as gastrointestinal perforation, fistula, hemorrhage, and arterial thromboembolism. In particular, patients with liver cirrhosis (LC) show an increased risk of variceal bleeding. However, brain hemorrhage associated with the use of bevacizumab in patients with HCC and LC is extremely rare. We encountered two cases of brain hemorrhage in patients with HCC and LC who underwent treatment with atezolizumab and bevacizumab. One patient had no history of hypertension, while the other patient had hypertension that was well-controlled with medication and an unruptured brain aneurysm located on the right side of the anterior communicating artery. Both patients experienced brain hemorrhage after two treatment cycles of atezolizumab with bevacizumab. One patient died due to brain hemorrhage, while the other patient recovered from subarachnoid hemorrhage with successful coil embolization. This case report suggests that if a patient has any high-risk factors associated with brain hemorrhage, physicians should thoroughly consider alternative treatment options for advanced HCC, as brain hemorrhage could be fatal.

The objective of this study was to investigate clinical manifestations of lower extremity edema (LEE) in endometrial cancer Medical records for LEE and/or responses to the Gynecologic Cancer Lymphedema Questionnaire (GCLQ) were evaluated in 177 patients with endometrial cancer Patients had a median age of 53 years. Sixty-seven patients (37.9%) had past (9 patients, 13.4%) and/or current patient-reported LEE (58 patients, 86.6%). Symptoms reported on the GCLQ in over 20% of respondents were swelling, numbness, aching , and heaviness. GCLQ total symptoms score was significantly higher in patients with current LEE. Most of the LEE (43/67, 64.2%) developed within 12 months after surgery and LEE lasted more than 6 months in most patients (56/59, 94.9%) Prospective clinical trials are needed to know the clinical significance, impact on quality of life, and preventive strategy of LEE in patients with endometrial cancer

<P><B>Abstract</B></P> <P>Improving the efficiency of the oxygen reduction reaction (ORR) for use in commercial fuel cells has been the subject of diverse synthetic research activities. However, due to their inferior catalytic performance and dispensability, there are still limitations to achieving breakthroughs regarding ORR catalytic activity using carbon nanomaterials, despite their high electron-transfer and mass-transport properties. In this study, we mimicked nature by using a biomineralization approach for controlling the growth of inorganic materials and demonstrated improved ORR values. The designed peptide, Hexcoil-Ala, is able to supramolecular assembly on single-walled carbon nanotubes (SWNTs), leading to SWNTs that are well dispersed in aqueous solution. In order to direct gold nanoparticle (AuNP) nucleation sites, we substitute two residues in Hexcoil-Ala with cysteine to provide the mutated peptide, HexCoil-Ala-2Cys. This peptide affords a sophisticated, size-controlled, and well-dispersed arrangement of AuNPs. High-resolution transmission electron microscopy studies confirmed the homogeneously well-aligned distribution of nanosized AuNPs on the HexCoil-Ala-2Cys structure, along the direction of SWNT axis. The (AuNPs/P-SWNT) composite in water provides dispersed and stable metallic nanoparticles of electrostatically modified Au through synergistic effects involving the peptide. Consequently, this catalyst exhibits improved ORR performance compared to bulk gold and even, in case of number of electrons (<I>n</I>) transferred, higher than the number of Pt/C. X-ray photoelectron and Raman spectroscopies reveal the details of the electronic interactions among the components of the AuNP/P-SWNT composite, and how they facilitate the four-electron reaction pathway. This study provides valuable information for the optimization of catalyst synthesis and precise particle-size control, leading to stable, water-dispersive composites, with improved electronic properties for enhanced ORR performance in fuel cells.</P> <P><B>Highlights</B></P> <P> <UL> <LI> We used designed peptide to direct nucleation sites of gold nanoparticles. </LI> <LI> The designed peptide offers size-controlled and well-dispersed arrangement of AuNPs. </LI> <LI> Also, the superstructure of AuNPs was modified electrostatistically by the peptide. </LI> <LI> It exhibits improved ORR performance with higher number of electrons(<I>n</I>) transferred. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>In this present work, we describe improved electrocatalytic reaction of directly gold nanoparticle assembled superstructures using the programmed supramolecular protein assembly.</P> <P>[DISPLAY OMISSION]</P>
