  • This study was aimed to investigate factors that affected the status of wearing personal protective equipment (PPE) for handling poultry carcasses with potential exposure to virulent avian infectious agents. A large outbreak of high pathogenic avian influenza (HPAI) occurred in South Korea in 2014. Many public officers participated for euthanizing and handling livestock carcass. However, several safety issues with using PPE were revealed. Therefore, a questionnaire survey was conducted for 340 people who participated euthanasia and carcass disposal in the place where HPAI mainly occurred in 2014. It was found that 31.8% of the respondents had ever taken off their protective equipment during operations because of its inconvenience. The most inconvenient PPE was goggles (54.6%), followed by mask (20.2%), latex gloves (11.6%), shoe covers (5.9%) and protective clothing (5.3%). The main complaints about this individual PPE was unclear sight, damp emitted toward eye, sweating, tearing easily and sweating, respectively. Considering such problems of PPE, new possible directions for improvement of gloves and goggles were suggested. With newly developed rubber coating fabric gloves and conventionally using latex and fabric gloves, H3N2 influenza virus transmission experiment was conducted. Rubber coating fabric gloves showed similar efficiency for blocking virus transmission with latex laboratory gloves and were not easily torn by sharp claws of chicken. In addition, air flow control safety eyewear was suggested to minimize moisture formation. The air flow control system efficiently suppressed moisture formation inside the goggles. Therefore our study will provide more specific directions about new PPE development for safety protection of actual wearers.

  • As the supply of photovoltaic (PV) increases worldwide, the cumulative installations in 2018 were 7.9 and 560 GW in Korea and the world, respectively. Typically, when the ground on commercial PV modules is installed, the area is limited; hence, new designs of PV modules are required to install additional PVs. Among the new design of PV modules, lightweight PV modules can be utilized in PV systems, such as buildings, farmlands, and floating PV. Concerning the investigation of lightweight PV modules, several studies on materials for replacing low-iron tempered glass, which comprises approximately 65% of the PV module weight, have been conducted. However, materials that are used as substitutes for glass should possess similar lightweight properties and reliability as glass. In this study, experimental tests were performed to evaluate the applicability of ethylene tetrafluoroethylene (ETFE) film with excellent resistance to water and aging as a front material of PV modules. The transmittance and ultraviolet properties of the ETFE film were determined and compared with those of glass. A 1-cell module and laboratory-scale 24-cell module were manufactured using the ETFE film and glass, and the electrical output was measured and analyzed. Furthermore, damp heat and thermal cycle tests were conducted to evaluate the reliability of the ETFE film module. Based on the experimental results, the electrical output and reliability of the ETFE film module were similar to those of the glass module, and the ETFE film could be used as the front material of PV modules.

  • Vertigo is one of the subjective symptoms which appears commonly in so many diseases that it is often neglected. But it needs active medical care because it can be a forewarning of serious illness like cerebral apoplexy. This thesis makes a study of vertigo in view of Hyungsang medicine. The followings are the conclusion drawn in diagnosis and treatment of Vertigo: Excess in the upper and deficiency in the lower part(上實下虛) is a main cause of male vertigo. Deficiency in the upper and excess in the lower part(下虛上實) is a general cause of female vertigo. Vertigo is also caused by the insufficiency of the kidney water(腎水) or reservoir of marrow(髓海). persons of Jung pe(精科) with large check bones , those of Fish type(魚類) with Dig mouth and thick lips ; and those with large heads are mainly attacked by this cause. A fleshy person's vertigo comes from the deficiency of Ki and damp phlegm(氣虛濕症) so it is cured by reinforcing Ki, removing dampness and dispelling phlegm. A slim person's vertigo comes from the deficiency of blood and dryness heat(血虛有火) so it is treated by tonifying the blood, cleaning heat away the heat. In case of womanly shaped male and manly shaped female, the vertigo is due to the phlegm fire. Wind-heat(風熱) can cause vertigo generally 施 the persons of following types : wind type(風人), running animal type(走類),bird type(烏類), and Yangmyung meridian type (陽明形). Vertigo also comes from consumption. The deficiency of Ki can be a cause of vertigo in case of male; persons with pale complexion; and those with pronounced noses. The deficiency of blood can be a reason of vertigo in the persons of Hyul type(血科) and those with pale eyelids and lips. The hypofunction of the splean and stomach brings on the deficiency of Ki and blood, which can give rise to the vertigo for those with large nose and mouth. The old people's vertigo comes from the hypofunction of Ki, blood, Yin and Yang.

  • Perovskite solar cells (PSCs) can be fabricated through solution process economically with variable bandgap that is controlled by composition of precursor solution. Tandem cells in which PSCs combined with silicon solar cells have potential to reach high power conversion efficiency over 30%, however, lack of long-term stability of PSCs is an obstacle to commercialization. Degradation of PSCs is mainly attributed to the mass transport of halide and metal electrode materials. In order to ensure the long-term stability, the mass transport should be inhibited. In this study, we confirmed degradation behaviors due to the mass transport in PSCs and designed buffer layers with LiF and/or SnO2 to improve the long-term stability by suppressing the mass transport. Under high-temperature storage test at 85℃, PSCs without the buffer layers were degraded by forming PbI2, AgI, and the delta phase of the perovskite material, while PSCs with the buffer layers showed improved stability with keeping the original phase of the perovskite. When the LiF buffer and encapsulation were applied to PSCs, superior long-term stability on 85℃-85% RH dump heat test was achieved; efficiency drop was not observed after 200 h. It was also confirmed that 90.6% of the initial efficiency was maintained after 200 hours of maximum power tracking test under AM 1.5G-1SUN illumination. Here, we have demonstrated that the buffer layer is essential to achieve long-term stability of PSCs.

  • Oiled paper (Yuji, 油紙) is an oil impregnated paper which was one of the daily necessities in Korea. As there has not been any accurate research on this subject, this study examined the literature from the Joseon Dynasty to study its origin, nomenclature, usage and production process. Goryeodogyeong (高麗圖經) and Goryeosa (高麗史) allowed the estimation that the origin of oiled paper was the Goryeo Dynasty, but the records of oil and paper in Samguksagi (三國史記) and Nihon Shoki (日本書紀) indicate the possibility that the production of oiled paper can be traced back to the 7th Century. The nomenclature and the usage of oiled paper in the Joseon Dynasty were examined through the Annals of Joseon Dynast (朝鮮王朝實錄), Ilseongnok (日省錄) and Seungjeongwonilgi (承政院日記), while the Royal Protocols of the Joseon Dynasty (Uigwe, 儀軌) and Takjijunjeol (度支準折) together with other literature were examined for its market value, use and materials. The literature from the Joseon Dynasty indicate that oiled paper was used for various everyday commodities with its waterproof, damp-proof and transparent properties and called in various ways according to its use and production process. This study studied the literature on oiled paper from the Joseon Dynasty, but the studies on the restoration of traditional oiled paper are still needed. Therefore, it would be necessary to study the traditional oiled papers in combination with the study of oiled paper relics, the reproduction of traditional oiled paper samples, and the case study of the papermaking masters who have been producing the traditional oiled papers.

  • The interstitial cells of Cajal (ICCs) are the pacemaker cells in the gastrointestinal (GI) tract. In the present study, the effects of olanzapine, an atypical antipsychotic agent, on pacemaker potentials in cultured ICCs from the small intestine of the mouse were investigated. The whole-cell patch-clamp configuration was used to record pacemaker potentials from cultured ICCs. Olanzapine produced pacemaker depolarizations in a concentration-dependent manner in current clamp mode. Methoctramine, a muscarinic $M_2$ receptor antagonist, did not inhibit olanzapine-induced pacemaker depolarizations, whereas 4-diphenylacetoxy-N-methylpiperidine methiodide (4-DAMP) muscarinic $M_3$ receptor antagonist did inhibit it. When guanosine 5'-[${\beta}$-thio] diphosphate (GDP-${\beta}$-S; 1 mM) was in the pipette solution, olanzapine-induced pacemaker depolarization was blocked. Also, low $Na^+$ solution externally eliminated the generation of pacemaker potentials and inhibited the olanzapine-induced pacemaker depolarizations. Additionally, the nonselective cation channel blocker, flufenamic acid, inhibited the olanzapine-induced pacemaker depolarizations. Pretreatment with U-73122, an active phospholipase C (PLC) inhibitor, also eliminated the generation of pacemaker potentials and suppressed the olanzapine-induced pacemaker depolarizations. These results suggested that olanzapine modulates the pacemaker potentials through muscarinic $M_3$ receptor activation by G protein-dependent external $Na^+$ and PLC pathway in the ICCs. Therefore, olanzapine could affect intestinal motility through ICCs.
