Objectives: The aim of this study was to investigate whether the health status of Republic of Korea Air Force (ROKAF) soldiers changed after one year of military service. Methods: We selected 483 ROKAF soldiers from the 11 749 recruits who participated in the 2011 physical examination. The selected soldiers underwent another physical examination in 2012 for advancement to senior airman. Data from 2011 and 2012 were merged. To collect data on lifestyle, a questionnaire was sent to all included subjects via the military intranet e-mail service. Results: The percentage of recruits with an abnormal alanine transaminase level (normal range <40 IU/L) decreased from recruitment (13.7%) to the following year (2.7%). Moreover, the percentage of obese soldiers (body mass index ${\geq}25kg/m^2$) decreased from recruitment (20.5%) to the following year (10.4%). There was a significant change in mean duration of exercise carried out each day before ($0.8{\pm}1.3$ hours) and after ($1.0{\pm}0.7$ hours) joining the ROKAF service. Conclusions: These ROKAF soldiers were generally in good health before and after joining the armed service. After one year of military service, the health status of most soldiers improved, especially with respect to body mass index and alanine transaminase level.

Methallylescaline, 2-(3,5-dimethoxy-4-[(2-methylprop-2-en-1-yl)oxy]phenyl)ethanamine, is a new psychoactive substance with potent agonist of 5-HT receptor, but there is little information on its pharmacological effect, metabolism, and toxicity. It is necessary to characterize the metabolic profiling of methallylescaline in human hepatocytes using liquid chromatography-high resolution mass spectrometry. Methallylescaline was metabolized to three hydroxy-methallylescaline (M1-M3) and dihydroxy-methallylescaline (M4) via hydroxylation in human hepatocytes. CYP2D6, CYP2J2, CYP1A2, and CYP3A4 enzymes were responsible for the metabolism of methallylescaline. The metabolites as well as methallylescaline would be used for monitoring the abuse of methallylescaline.

Inflammatory pseudotumor (IPT) is a term defining a mass characterized microscopically by a proliferation of bland mesenchymal spindle cells infiltrated by diffuse mixed inflammatory cells with a predominance of plasma cells and lymphocytes. Here, we show the primo vessel-like structure of the primo-vascular system (PVS) in a dog with IPT. A 6-years old male Mongrel dog was diagnosed with an abnormal mass (diameter 5.5 cm, weight 22 g) near left preputial area. The dog was submitted to the surgical detectomy of the mass. During the surgical operation, we observed primo vessel-like material. After fixations, the masses appeared macroscopically as lipoid-like, firm, white to grey masses, measuring $5{\times}8cm$. Histologically, cellular infiltration into the muscular layers was frequently seen. The mesenchymal proliferation remained the main component of the mass and was composed of myofibroblastic-like spindle cells characterized by globular, irregular nuclei containing open chromatin and a prominent nucleolus. On the basis of the histopathologic lesions, the subcutaneous mass was diagnosed as IPT. Also, we detected a primo vessel-like structures in some areas of the IPT tissues. These were observed as novel thread-like structures and bundle of tubular structures. To our knowledge, this report is the first case of primo vessel-like structure in a dog with IPT.

Purpose: This study examined the patterns of drugs, poisons, and chemicals detected in autopsy samples performed in the Seoul Institute and other regional forensic offices of the National Forensic Service (NFS) between 2014 and 2016. Methods: The investigation carried out using the laboratory information management system. Forensic toxicological identification and quantitation were performed in autopsy samples, including heart blood, peripheral blood, liver, kidney, vitreous humor and etc. Gas chromatography/mass spectrometry (GC-MS) and liquid chromatography-tandem mass spectrometry (LC-MS/MS) were used to analyze the drugs and poisons. Results: Forensic autopsies were performed on 9,674 cases in this period. Based on the autopsy reports, 699 cases (7.2%) were considered as unnatural deaths caused by fatal intoxication. The number of male deaths was higher than that of female deaths, with the age of 50-59 being the most common age group. Conclusion: Drugs comprised the largest number of deaths due to poison, followed by alcohol, agrochemicals, drug with alcohol, carbon monoxide, and cyanide, in that order. Zolpidem was the most frequently used drug in all drug-related intoxication cases.

국립공원관리공단 종복원기술원의 수컷 여우(8년령, 8.5 kg)에서 경부에 결절상의 증식물이 발견되었다. 진단을 위하여 방사선 검사와 초음파, 일반혈액검사, 혈청 화학분석, 혈액 도말 검사를 실시하였고 증식물은 외과적으로 절제하였다. 절제술 후 얻은 조직 샘플을 10% 중성 포르말린 고정 후 HE 염색하였다. 해당 동물의 혈액 수치는 일반 여우와 크게 다르지 않았다 증식물은 육안으로 보았을 때 주변조직과 잘 구획되어 있었으며 둥글고 하얀 형태였다. 조직 슬라이드 현미경 검사 후 이는 성숙 지방 조직으로 이루어진 지방종으로 진단되었다. 지방종은 반려동물에서 흔히 발생하는 양성 종양이나 현재까지 여우에서는 보고된 적이 없으며, 이 증례는 여우에서 지방종을 종합적으로 진단 평가한 최초 증례이다.

Currently, the world has experienced a mass exodus of workforce from the manufacturing industry to service related industry. In addition, the changes of industry structure toward service industry have been gradually accelerated. We have felt that it is time to conduct researches about IT service systematizing and discovering the essence of service itself with scientific and synthetic ways based on Service Science. For Service Science researchers, service identification is regarded as a difficult activity when they contact it for the first time and they want to apply it real environment. In reality, there exist mismatches between business and IT service to identify service since service is identified from the business point of view in Service Science area and it is identified from the technical point of view in IT service area. In this paper, we have conducted researches about service identification placed on the first priority and regarded as difficult area in service-oriented business area. To lessen aforementioned difficulties, we propose procedures and methods for extracting and identifying service in the viewpoint of business process. We conducted case study and comparison with existing researches to verify the applicability and the excellence of our proposal.

대량 생산은 오랫동안 다양한 제품 생산방법으로서 기업의 전략을 수립하는 데 있어 가장 중요한 생산 패러다임이었다. 하지만 기업의 경쟁 환경과 소비자의 요구가 다양화함에 따라 이제는 대량 생산이 가장 중요한 패러다임이 될 수 없다. 특히 소비자들의 요구사항은 더욱 다양해지며, 빠르게 변화하여 기업들은 소비자들의요구에 대응하기 힘들어 지고 있다. 대량 맞춤(Mass Customization)은 이런 흐름을 반영하여 가장 주목 받는 패러다임으로서 대량 맞춤은 고객의 요구에 맞춘 다양한 제품을 저렴한 비용으로 생산해 내는 것이 목적이다. 본 연구에서는 프로덕트 아키텍처 시스템(Product Architecture System)의 이론과 개념을 활용하여 대량 맞춤형 서비스를 실현하는 방법을 구체화하였고 이를 캠핑카의 내부 퍼니처 모델 중심으로 사례 연구하였다. 특히 기존에 기업에서 생산성을 중심으로 제품 플랫폼(Product Platform)과 모듈(Module)을 개발하던 것과는 달리, 소비자의 요구사항을 최우선으로 반영하여 제품 플랫폼(Product Platform)과 모듈(Module)을 개발하고 구성하는 방법을 제시하였고, 그 효용성에 대해 고찰하였다. 연구 결과로는 프로덕트 아키텍처 시스템의 내부 요인을 통해 디자인하고 외부 요인으로 결과물의 효과성을 검증하여 교체성, 재활용성, 라인업, 충전성 등에서 효과적임을 확인할 수 있었다. 추후 프로덕트 아키텍처 시스템을 활용한 디자인 프로세스를 통해 추가적인 실증연구로 이어지길 기대한다.

4차 산업혁명 시대에 서비스기업에서도 각기 다른 다양한 차별화 정책을 내세우고 있다. 기존까지 단순하게 고객을 만족시켜 매출을 높이기위한 방법이 아닌 좀 더 원시안적 시각을 갖고 서비스를 제공하는 직원들의 마인드와 그들이 느끼는 환경에 대한 중요성이 점차 커지고 있다. 서비스기업은 궁극적으로 고객만족, 품질향상, 가치 있는 경영 등 긍정적인 경영성과를 나타내기 위하여 끊임없는 노력을 기울이고 있으며 다른 산업에 비하여 직원에 대한 높은 의존도를 가지고 있다. 따라서 고객들을 직접적으로 응대해야하는 서비스제공자인 직원의 마음가짐과 부여된 환경, 역량 등이 직 간접적으로 고객만족 및 성과에 큰 영향을 미칠 수 있다. 궁극적인 조직의 성과를 높이고 경쟁우위를 갖추기 위해서는 결국 서비스 제공자인 직원들에 대하여 개인역량 개발, 근무환경 지원 등 다양한 형태의 사회적 지지가 중요하다고 할 수 있다. 따라서 본 연구에서는 사회적 지지가 서비스종사원의 긍정심리자본, 창의성, 직무성과에 미치는 영향에 관한 연구에 대한 후속연구로 서비스프로세스 메트릭스 가운데 대량서비스영역인 도매점, 소매점, 학교, 은행 등에 종사하는 직원들을 대상으로 동료지지가 자기 효능감을 통하여 성과에 어떠한 영향을 주는지 살펴보았으며, 그 결과 총 3개의 가설 중 3개 모두 채택되었다. 동료와 전반적인 관계가 원활해지면 자기 효능감 또한 향상되고, 자기효능감이 높을수록 직무성과도 높게 나타나며, 동료와 업무적으로나 업무이외에 전반적으로 의지할 수 있다고 느끼는 경우 직무성과도 높게 나타나는 것을 알 수 있다. 본 연구는 대량서비스영역에 종사하는 직원들을 실증분석 대상으로 한 관련연구는 전무한 실정으로 지금까지 연구와는 좀 더 다른 관점으로 접근하여 서비스기업의 경쟁력을 높이기 위한 인적자원관리 측면에서의 전략을 좀 더 효율적이고 효과적으로 제시하여 관련 시사점을 제시하고자 한다.

In spite of the development of the service industry, research on measuring customers' service satisfaction is far insufficient. Therefore, ways to measure the service quality accurately need to be established due to the ambiguous types of service business. This research classifies the types of service business into service factory, service shop, mass service, professional service by using Schmenner's Service Process Matrix and conducts research on domestic literature that measured service satisfaction with Servqual and ServPerf. This study intends to suggest guidelines to measure customer satisfaction according to types of service business by researching ways to measure service satisfaction according to the types of service business and analysing the actual application methods based on a table that summarizes previous research on Servqual and Servperf.
