Spectral energy distribution camera for QUasars in EArly uNiverse (SQUEAN) is a successor of Camera for Quasars in EArly uNiverse (CQUEAN) which was developed by Center for the Exploration of the Origin of the Universe and operated at the 2.1 m Otto Struve Telescope in the McDonald Observatory, USA, since 2010. The software of SQUEAN controls a science camera, a guiding camera, and a filter wheel, and communicates with the telescope control system (TCS). It has been constantly revised and modularized according to the upgrades of the TCS and the hardware changes. Recently we have implemented the stable network communication and the semi-automatic focusing modules to enhance observational convenience. In this presentation we describe the current status of the SQUEAN control software and introduce a software architecture which is optimized on efficient astronomical observations.

Candidiasis is one of the most common causes of late-onset infection among very-low-birth-weight infants (VLBW) in most neonatal intensive care units and is associated with significant morbidity and mortality. Standard therapy consists of the administration of amphotericin B, amphotericin B complex, and fluconazole. In many cases, candidiasis is not easily eradicated, despite the administration of these drugs. We report our experience of the addition of high-dose caspofungin to the conventional antifungal drugs in a VLBW infant with refractory candidemia.

The purpose of this study is to report the effect of Korean medicine rehabilitation therapies in two patients with ankle fractures who underwent Open Reduction with Internal Fixation (ORIF). Two patients with fractures who received ORIF received acupuncture, electroacupuncture, herbal medicine, and physical therapy during hospitalization. Patients were evaluated for AOFAS score, NRS, ROM, and ankle circumference. Case 1 was improved from 30 points to 62 points on the AOFAS score, from 8 to 2 on the NRS, and from 33 cm to 30 cm on the ankle perimeter. ROM was improved in all directions. Case 2 showed an AOFAS score of 64 to 90 points, frome 5 to 2 on the NRS, and from 25 cm to 23.5 cm on the ankle perimeter. ROM was improved in all directions. The results of this study suggest that the treatment of Korean medicine has a meaningful effect on improvement and rehabilitation of ankle fracture patients who have received ORIF.

In this work, ZnO shell on mesoporous $SiO_2$ ($ZnO/SiO_2$) was prepared by atomic layer deposition (ALD). Diethylzinc (DEZ) and $H_2O$ were used as precursor of ZnO shell. $ZnO/SiO_2$ sample was characterized by X-ray diffraction (XRD), N2 sorption isotherms, X-ray photoelectron spectroscopy (XPS), Scanning electron microscopy (SEM) and Fourier-transform infrared spectroscopy (FT-IR). $ZnO/SiO_2$ showed higher adsorption capacity of MB than that of bare mesoporous $SiO_2$ and the adsorption capacities of $ZnO/SiO_2$ could be regenerated by UV exposure through the photocatalytic degradation of the adsorbed MB. This system could be used for removing organic dye from water by adsorption and reused after saturation of adsorption due to its photocatalytic regeneration.

We report a facile method to fabricate superhydrophobic, transparent and conductive film using multi-walled carbon nanotubes (MWCNTs) which are coated by polydimethylsiloxane (PDMS). In order to prepare a film, PDMS coated MWCNTs were dispersed in solvents and the solution was drop-casted on substrates. It was demonstrated that the PDMS coating enhanced the dispersion of MWCNTs in diverse solvents such as dimethyl formamide(DMF) and acetone without the use of acids or surfactants, which are the common methods. In the case of DMF solvent, dispersion of MWCNT was improved by 40 % upon PDMS-coating of MWCNT. Enhanced dispersion of MWCNTs made it possible to fabricate transparent and conductive film homogeneously on the substrate and PDMS-coating on MWCNTs also made the surface hydrophobic. We can fabricate a uniform and multifunctional MWCNT film (transparent, conductive, superhydrophobic and flexible) which is applicable on large area without any physical damage and expensive equipment.

We report a simple method for preparing hydrophobic mesoporous silica and its use as a pre-concentrating agent of gas analytes. Hydrophobic mesoporous silica was prepared by coating PDMS (polydimethylsiloxane) thin layer on commercial mesoporous silica with thermal deposition method in a sealed chamber. By using this method, we were able to coat PDMS layer on inner-walls of pores larger than 15 nm. Also, contact angle measured on a surface consisting of PDMS-coated mesoporous silica exceeded $150^{\circ}$, implying that the surface has high water repellency. Pre-concentration ability of PDMS-coated mesoporous silica and baremesoporous silica was tested under dry and humid conditions. Adsorption and molecular desorption of gas analytes was much enhanced by PDMS-coating on mesoporous silica under both dry and humid conditions. Therefore we suggest that PDMS-coated mesoporous silica can be an efficient pre-concentration agent in order to enhance sensitivity of various detectors.

President Park Geun-hye Administration has established the Ministry of Science, ICT and Future Planning (MSIP) to build a creative economy using Information and Communication Technology (ICT). July 2, 2013, The National Assembly has legislated the special act on the ICT promotion and convergence so called special ICT Act. This special ICT Act has reduced the legal basis through legislative process and departmental agreement. Therefore many experts worried that since the MSIP's key functions and roles are being reduced, there will be a limit to the MSIP's endeavor for the advancement of science technology and the ICT promotion and convergence. The establishment of the Agency, together with the formation of 'IT Strategy Committee', is considered to be one of the core items of the Special Act on ICT. MSIP originally planned to integrate the ICT R&D functions scattered across many governmental organizations, including Korea Communications Agency (KCA), KEIT and Korea Creative Contents Agency (KOCCA), into the Agency to separate the national ICT R&D from private R&D and streamline the process of 'discovery-selection-evaluation-commercialization'. The analytical results in this study are supposed to the establishment of efficient ICT governance systems as the practical strategies to actively cope with the changes of ICT convergence environment. It is also expected to the revision on the special ICT Act in the ICT budget and governance. Therefore, MSIP should cover research and development (R&D) as well as major ICT promotion functions to a creative economy.

The purpose of this study is to investigate the effect of floor area ratio incentive system for Long-life housing certification system by simulation of five recently built apartment complexes. Apartments that are certified as superior in Long-life housing can receive 10% of the floor are incentive in Seoul. However, the difference between base and permitted floor area ratio are in general residential area of class 2 and 3 is not more than 20%. limit of feasible allowance incentive is limited. Even if there is an unrealized permitted floor area ratio, there is no reason to apply the Long-life housing certification system preferentially. Because the items of the floor area ratio incentive provided by the District Unit Plan are various, it shows that the floor space ratio incentive for Long-life housing certification system has little effectiveness. To enhance the feasibility of incentives for the Long-life housing certification system, improvement in the urban planning level, including district unit planning, including the design criteria for apartments in Seoul, is needed.

This study focuses on the fact that the past government has been consistent with the one-sided withdrawal policy without any clear countermeasures in relation to the ongoing nuclear development of the DPRK. The purpose of this study is to improve the understanding of South Korea's North Korea policy and to present the direction of the North Korea policy in the future by comparing and researching the North Korea policy pursued by Lee Myung - bak government / Park-Geun-Hye government. Such an attempt will provide a basis for evaluating the previous government's policies toward North Korea, and will also help to find alternatives to sustainable inter-Korean relations and North Korea policy to achieve a unified Korea.

Gastric volvulus is an uncommon clinical entity. There are three types of gastric volvulus; organoaxial, mesenteroaxial and combined type. This condition can lead to a closed-loop obstruction or strangulation. Traditional surgical therapy for gastric volvulus is based on an open approach. Here we report a successful case of a patient with chronic gastric volvulus with a laparoscopic treatment. A 79-year-old woman came to the emergency department with epigastric pain accompanied by nausea for 2 weeks. Abdominal computed tomography revealed markedly distended stomach with transposition of gastroesophageal Junction and gastric antrum. Barium meal study revealed presence of the antrum was folded over 180 degrees that was located above gastroesophageal junction. We attempted an endoscopic reduction, but it was unsuccessful. The patient got laparoscopic anterior gastropexy. Based on our result, laparoscopic gastropexy can be considered as a good choice of the treatment for gastric volvulus.
