서비스경제철학으로서의 한국고유사상 정합성연구

김현수,Kim, Hyunsoo 서비스사이언스학회 2017 서비스연구 Vol.7 No.3

The current research investigates the basic philosophy that would serve as a foundation for the development of the service economy. In particular, the current work suggests that the Korean traditional philosophy fits the philosophy of the service economy because of the relational nature of the Eastern culture (vs. Western culture). Therefore, it is suggested that trough manifestation of the Korean traditional philosophy, the service economy would be invigorated. The yin-yang and the Two Taegeuk do not emphasize the role of human, and thus, a new philosophy incorporating this aspect needs closer attention. Therefore, the Korean traditional philosophy, structured in a Three Taegeuk framework could serve as the foundation for the development of the service economy. The Three Taegeuk framework relates to the harmonization, horizontality, bi-directionality, and relational aspects of the service industries. For example, human serving the agent role in the society resembles the current service economy where service workers and customers serve important roles in value creation. Taken together, the current research suggests that the Korean traditional philosophy serve as an important foundation for the development of the service economy.

산업간 경계해체 시대의 서비스R&D 전략

김현수,Kim, Hyunsoo 서비스사이언스학회 2017 서비스연구 Vol.7 No.2

The current research investigates the service R&D strategies from the service's nature perspectives. In the current economy, manufacturing and service industries are becoming boundless, and thus, they are competing with each other in a customer-centric environment. Because customers' needs and wants are realized through services, service industry has become one of the most important industries in the world. However, there have been conflicting opinions about service R&D policies due to different definitions of services. The current research specifically focuses on the nature of services to discuss strategies for service R&D. Service R&D strategies are suggested considering the nature of the current economy where industries are becoming boundless. In addition, the current research considers the service's relational, bidirectional, horizontality, and harmonization nature of services, and also, intangibility, inseparability, heterogeneity, perishability were considered in suggesting strategies for service R&D. For manufacturing industries, strategies to strengthen servitization R&D were proposed, and for service industries, strategies to strengthen manufacturization R&D were proposed. The results from the current research can be used for developing corporate service R&D strategies, and developing policies for developing both service and manufacturing industries in the current economy.

스마트폰 기반 MLSTM-FCN + SE + 다중 어텐션 하이브리드 모델을 이용한 고령자 도시 보행 장애요소 탐지 연구

김현수,Kim, Hyunsoo 인천대학교 도시과학연구원 2025 도시과학 Vol.14 No.1

This study proposes a deep learning framework for detecting urban walking barriers using only smartphone accelerometer data. The proposed model integrates Multi-layer Long Short-Term Memory (MLSTM) and Fully Convolutional Networks (FCN) in a hybrid parallel architecture, enhanced with Squeeze-and-Excitation (SE) blocks and a Multi-Head Attention mechanism. These modules enable the model to simultaneously capture long-term temporal dependencies and channel-wise spatial importance from tri-axial acceleration sequences. To validate the framework, a simulation-based walking dataset representing both elderly and adult pedestrians was constructed, including diverse urban environmental conditions such as uneven pavements, curbs, and surface irregularities over a 2 km walking path. The model was trained using AdamW optimizer and focal loss with multiple signal augmentations, achieving an F1-score of 0.88 and PR-AUC of 0.90, outperforming baseline models such as CNN, Bi-LSTM, and standard LSTM-FCN. Visualization through attention-weight maps confirmed that the model selectively focuses on acceleration perturbations associated with environmental barriers. This research demonstrates the feasibility of smartphone-based urban walkability assessment, offering a scalable and non-invasive approach to identifying hazardous walking environments for elderly pedestrians and informing urban accessibility improvements.

서비스본질 기반의 서비스산업 정책방안

김현수,Kim, Hyunsoo 서비스사이언스학회 2017 서비스연구 Vol.7 No.1

The current research investigates the strategies for fostering service industries from the service's nature perspectives. Because the service industry is broad and heterogeneous in nature, if service's nature is not considered in building strategies for developing service industries, it would have a limited perspective, and thus, it would be difficult to foster large growth in service industries. In addition, not considering service's nature would not encourage synergy among service sectors nor encourage innovative development among individual sectors. Therefore, we need to understand that different service sectors are all under the umbrella for service industries, and consider the service's nature. The current research considers the service's relational, bidirectional, horizontality, and harmonization nature of services, and also, intangibility, inseparability, heterogeneity, perishability were considered in suggesting strategies for fostering service industries. These results can be used to developing governmental policies for developing service industries.

김현수,신손문,고선영,이연경,박성원,Kim, Hyunsoo,Shin, Son Moon,Ko, Sun Young,Lee, Yeon Kyung,Park, Sung Won 대한유전성대사질환학회 2016 대한유전성대사질환학회지 Vol.16 No.1

Objective: Newborn screening leads to improved treatment and disease outcomes, but false-positive newborn screening results may impact include parental stress and anxiety, perception of child as unhealthy, parent-child relationship dysfunction, and increased infant hospitalizations. The purpose of this study was to investigate of the false positive rates and the causative factors of false positive results in Tandem Mass Spectrometry (TMS) in single center. Methods: Records were reviewed for all 18,872 subjects who were born in Cheill General Hospital, during January 1st, 2012 to December 31st, 2014. 17,292 neonates (91.62%) were tested for tandem mass screening almost in 2-5th day of life. Newborn babies whose first results were abnormal had been tested repeatedly by same methods in 7-14 day. If the results were abnormal again, further evaluation was performed. TMS analysis included data for the 43 disorders screened for using TMS broken down into three categories: fatty acid oxidation disorders, organic acidurias, and aminoacidopathies. The impact of several factors on increased false positive rates was analyzed using a multivariate analysis: time from birth to sample collection, birth weight, birth height, BMI, gender, gestational age, delivery type. Results: Males of the subjects were 8942 (51.7%), female 8350 (48.3%), the mean gestational age was $38.6{\pm}1.7$ weeks, the average birth weight $3,155.6{\pm}502.4g$, the average birth height $49.1{\pm}2.9cm$, and the average BMI $13.0{\pm}3.8(kg/m^2)$. Vaginal delivery cases were 9713 (56.2%), caesarean section 7,579 (43.8%). The average date of the inspection was $2.8{\pm}1.1$ days. 224 cases were identified as TMS positive. All the subjects were false positive (222/17,292, 1.30%) except 2 cases (1 male; benign phenylketonuria and 1 female; Short chain acyl-CoA dehydrogenase deficiency). The false positive rates were 0.61% in fatty acid oxidation disorders, 0.25% in organic acidurias, and 0.45% in aminoacidopathies. In our study, the date of inspection got late, the false positive rates got higher. Because almost the cases of late test date were in treatment in neonatal intensive care unit so their test date was affected by their medical conditions. False positive rate was higher in extreme immaturity${\leq}27$ weeks than newborns of gestational age >27 weeks [OR=6.957 (CI=1.273-38.008), p<0.025] and extremely low birth weight<1,000 g than newborns of birthweight ${\geq}1,000g$ [OR=5.616 (CI=1.134-27.820), p<0.035]. Conclusion: False positive rate of TMS was 1.30% in Cheil General Hospital. Lower gestational age and birth weight impacted on increased false positive rates. Better understanding of factors that influence the reporting of screening tests, and the ability to modify these important factors, may improve the screening process and reduce the need for retesting. of screening tests, and the ability to modify these important factors, may improve the screening process and reduce the need for retesting.

17세기 전반 율곡학파예학(栗谷學派禮學)의 쟁점(爭點)과 경향(傾向)연구-『의례문해(疑禮問解)』,『의례문해속(疑禮問解續)』을 중심으로-

김현수 ( Hyunsoo Kim ) 한국철학사연구회 2014 한국 철학논집 Vol.0 No.41

본고의 목적은 『의례문해(疑禮問解)』·『의례문해속(疑禮問解續)』를 중심으로 17세기 전반의 율곡학파의 예학적 쟁점과 경향을 고찰하는 것이다. 『의례문해』는 사계 김장생과 문인들 사이에 이루어진 예문답서이며, 『의례문해속』은 신독재 김집과 문인들 사이에 주고받은 예문답서이다. 예문답서 혹은 예문답 서신은 구체적 상황에 대한 여러 의견이나 주장들을 확인하는데 유용한데, 특히 논란이 된 항목이나 주목할 만한 예문답을 통하여 당시의 예학흐름과 당사자들의 공통된 문제의식을 파악할 수 있다. 본고는 이러한 인식을 바탕으로 17세기 전반의 율곡학파의 예학적 특징을 드러내려 했다. 그 특징을 논하면 다음과 같다. 우선적으로 『주자가례』에 대한 체계적·심층적 접근이 이루어졌음을 지적하고 싶다. 즉 학문적 분석 및 고증적 측면이 강화된 측면을 엿볼 수 있는데, 가례도(家禮圖)에 대한 문답, 각종 의례절차 및 기물의 고증 등이 이를 방증한다. 더불어 고례(古禮) 및 주자(朱子), 정자(程子), 장자(張子)의 예설, 퇴계(退溪)·율곡(栗谷)·한강(寒岡) 등의 중국·한국 예설을 종합적 검토한다는 점도 이에 해당한다. 다음으로, ``종법(宗法)과 입후(立後)·봉사(奉祀), 기일(忌日), 반곡(反哭)과여묘제(廬墓制), 부재위모상(父在爲母喪), 개장(改葬), 기일(忌日), 묘제(墓祭)의 시기, 참신(參神)과 강신(降神) 순서 등 논란이 된 예문답을 통해 사계 김장생과 문인의 예설의 근거 및 공통된 예 인식에 살펴볼 수 있다. 우선 주자의 예설 및 「주자가례」에 근거하여 예를 규정하려는 경향이 강함을 엿볼수 있다. 이는 앞서 언급한 「주자가례」를 체계적·심층적 접근과 같은 궤를같이 한다. 그리고 율곡·구봉 등의 율곡학파의 예설을 비판적으로 계승하고, 예의 정신·원리를 강조하는 사유 속에서 인정(人情)을 근거로 시속(時俗)과의 절충을 도모하려는 특징들을 찾아볼 수 있다. This Paper is research for Yulgok School(栗谷學派)`s lixue(禮學) in the first half of 17c centering around Uiremunhae(疑禮問解) and Uiremunhaesuk(疑禮問解續). Uiremunhae and Uiremunhaesuk are a book between Kim Jangsaeng(金長生)·Kim Jip(金集) and his follower`s questions & answers about li. A book or letter of questions & answers about li is useful for comprehension of lixue`s opinion, especially questions & answers about controversial li shows their critical mind and a foundation of cognition for li. Thus I make showing then situation of Kim Jangsaeng and his follower in relates to understanding and performing Zhuxi`s family rituals on analyzing questions & answers about controversial li. Kim Jangsaeng·Kim Jip and his follower`s characteristic of lixue are several on analyzing Uiremunhae. First, Kim Jangsaeng and his follower researched for Zhuxi`s family rituals with systematic approach and in-depth research, and detailed in reference to the Classic of li, Zhuxi, Zheongyi(程이), Zangzai(張載)`s thoery of li and chinese lixue data, and Lee Hwang(李滉), Lee Yi(李珥), Song Yikpil(宋翼弼), Jeong Goo(鄭逑)`s thoery of li and korean lixue data. Next, on questions & answers about controversial li, Kim and his follower basically maintained following Zhuxi`s family rituals. Zonfa, sacrificial rituals and funeral rituals are all such that, and if there happened omission and contradiction in Zhuxi`s family rituals, they refered to Zhuxi`s theory of li on the collected works of Zhuxi and the analects of Zhuxi and searched righteous li by historial invesigation. Then, Kim and his follower critically were in succession to Lee Yi and Song Yikpil`s thoery of li. finally, They also had to considered then situation on li(Zhuxi`s family rituals` li and ancient li)`s operation and actualizatin on considering principle and mind of li.
