김수종 감사연구원 2017 감사논집 Vol.- No.29
In order to encourage government officials to actively manage their administrative work, the Board of Audit and Inspection has introduced the 'Indemnity System on Active Administration'. It is a system to protect the public servants who are responsible for partial mistakes or errors that occurred during the active administrative process. There is a consensus on the introduction of the system, but in order to apply it to the public societies, at least two issues must be discussed. First, we need to clarify the definition and understanding of the concept of ‘active administration’. Secondly, we also need to discuss on what extent will be the scope of active administration acceptable? In this study, we focused on interpreting the meaning of ‘active’ by considering ‘activeness of administration’ as the core of the concept of positive administration. In addition, we examined the criteria for judging whether the work done by officials is active or not, that is, what requirements should be met in order to recognize the indemnity for mistakes or errors that occurred in the process of active administration. 감사원에서는 공무원의 적극적인 행정을 유도하기 위해 2009년 1월부터 ‘적극행정 면책제도’를 도입하여 운용하고 있다. 공무원이 적극적으로 행정에 임하는 과정에서 발생한 부분적인 잘못이나 오류에대하여는 책임을 면해주는 등 일하는 공무원을 보호하자는 취지의 제도이다. 적극행정의 필요성과 적극행정 면책제도의 도입에 대한 공감대는 형성되었으나 이를 공직사회에 제대로 적용하기 위해서는 적어도 두 가지 사항에 대한 논의가 선행되어야 한다. 첫째, 적극행정이라는 개념에 대한 정의와 이해를 명확히 해둘 필요가 있고, 둘째, 이러한 적극행정 개념에 따라 이루어진 행정행위에 대한 책임성 기준을마련해 둘 필요가 있다. 본 연구에서는 행정에서의 ‘적극성’이라는 의미를 성실성이라는 공직자의 기본자세에 바탕을 두고 ‘책임이 따를 위험이 있음에도 불구하고 업무를 추진하려는 의지나 태도’로 이해하면서 적극행정 개념을 정리한다. 그리고 그 해석에 따라 적극행정인지 여부를 판단하는 기준, 즉 업무추진 과정에서 잘못이나 오류가 있더라도 적극행정으로 인정되어 면책받기 위해서는 어떠한 요건들이충족되어야 하는지를 살펴보았다

비용종을 동반한 만성 비부비동염 치료에서 생물학적 제제의 최신 지견
김수종,문지원,이흥만 대한이비인후과학회 2021 대한이비인후과학회지 두경부외과학 Vol.64 No.10
Chronic rhinosinusitis is a common chronic inflammatory condition of sinonasal cavities andoccurs with or without nasal polyps. Uncontrolled chronic rhinosinusitis with nasal polyp(CRSwNP) has a negative impact on an individual’s quality of life. Many studies have beenconducted for novel treatments targeting type 2 cytokines involved in CRSwNP such as interleukin(IL)-4, IL-5, IL-13 and immunoglobulin E. Biologics have recently been proven to improvethe nasal symptoms of CRSwNP and reduce the need for systemic glucocorticosteroids. Recently dupilumab, omalizumab and mepolizumab were approved by Food and Drug Administrationfor CRSwNP, and other biologics are under investigation. Large-scale and longtermclinical trials are needed for therapeutic effectiveness, and several questions remain regardingpatient selection, treatment algorithm, and cost-effectiveness. Nevertheless, emergingbiologics may offer a new therapeutic option for uncontrolled CRSwNP.

Comparative Statics under Uncertainty with the Monotone Likelihood Ratio Order
김수종,류수열 한국경제학회 2004 The Korean Economic Review Vol.20 No.2
In a simple two asset portfolio problem with one-risky and one-safe asset, Landsberger and Meilijson (1990) have shown that a monotone likelihood ratio (MLR) improvement of random returns of the risky asset increases the demand for the asset for all investors with non-decreasing utilities. However, their comparative static statement is made only for the simplest case where the payoff function is linear in both the choice and the random variable. This paper improves the robustness of their result in two ways. One is that the same comparative static statement can also be made for cases of non-linear payoffs. Another improvement is given by extending the admissible set of changes in randomness with the same utility settings. When the concerned payoff is linear in the choice variable, we show that the MLR order is unduly restrictive for the comparative static result and replace it with a more general type of change in randomness, called a “one-side monotone likelihood ratio with respect to a point.”

Nano-sized titanium oxide powders were synthesized by a polymer matrix technique using pulp and Titanium tetraisopropoxide (TTIP) as starting materials. The synthesized powders were characterized by XRD and FE-SEM. The particle size of the powders was controlled by preparation conditions, such as heat treatment temperature and time. After investigating various drying and heat treatment conditions, 50-100 nm sized homogeneous titanium oxide particles were obtained by treating at $600^{\circ}C$ for 1 h. The crystallization and rapid growth of particles was accelerated by increasing heat treatment temperature and time. Anatase phase generated below $600^{\circ}C$ transformed to the rutile phase with increasing heat treatment temperature. Moreover, above $800^{\circ}C$, heat treatment time had a very large influence on particle growth, and changing the heating condition also had a large influence on crystal growth.

폴리머 매트릭스를 전구체로 사용한 SrAl_(2)O_(4):Eu^(2+),Dy^(3+) 축광성 형광체의 합성 및 형광 특성
김수종 한라대학교 2007 論文集 Vol.10 No.-
SrAl_(2)O_(4):Eu^(2+), Dy^(3+) phosphor was synthesized by the impregnation method and its properties of photoluminescence and long-afterglow were investigated. The mixture of Sr(NO_(3))_(2), Al(NO_(3))_(2)·9H_(2)O, EuCl_(3)·6H_(2)O, DyCl_(3)·6H_(2)O, NdCl_(3)·6H_(2)O salts dissolved in distilled water and then impregnating into the polymer precursor. After drying the impregnated mixture, was heat treated at 900-1400℃ for 2h in N_(2)-H_(2) reduction atmosphere. Photoluminescence spectra showed a excitation along the wide wavelength of 250-450nm, and broaden emission with maxima peak at 360nm. Also, it showed a good long afterglow with decaying over 1000 sec after excitation illumination for 10 min. In addition, the microstructure and crystal structure of SrAl_(2)O_(4):Eu^(2+), Dy^(3+) powders were investigated by an SEM and XRD, respectively.

Synthesis of MgO nanoparticles using starch as precursor medium
김수종,한정화 한양대학교 세라믹연구소 2018 Journal of Ceramic Processing Research Vol.19 No.2
Nanocrystalline magnesium oxide (MgO) particles were prepared through liquid phase precursor (LPP) method usingmagnesium nitrate as starting material and starch as an impregnatig matrix. The materials obtained by LPP method weresubsequently annealed at 500-1,100 oC for 1-3 hrs to improve crystallinity and phase purity. Crystallization and the growth ofparticles were accelerated with increasing calcining temperature. Crystallization of MgO started around 500 oC, which thetemperature is pyrolysis of starch, cubic phase generated at 600 oC. Moreover, above 600 oC, calcining time had influence oncrystal growth. The obtained MgO nanoparticles were characterized by powder X-ray analysis (XRD), infrared (IR)spectroscopy, photoluminescence (PL), and field emission scanning electron microscopy (FE-SEM). The PL emission spectrumof MgO nanoparticles exhibits two emission peaks at 560 and 618 nm which are due to various structural defects. The cubiccrystal structure with crystalline size of 30-150 nm, is obtained at the calcination temperature of 500-900 oC.
