Points-of-Dispensing (PODs) 위치를 고려한 긴급물류창고 위치 선정

홍수민,우수한 한국물류학회 2023 물류학회지 Vol.33 No.4

The significance of choosing optimal locations for emergency facilities is emphasized both in natural disasters and public health emergencies like pandemics. To ensure effective management of emergency logistics, procurement, and distribution, it is crucial to consider the establishment of facilities such as Points-of-Dispensing (PODs) that facilitate fast and efficient distribution. Consequently, when deciding on the location of logistics warehouses as part of emergency logistics management, it is essential to take into account the positioning of temporary facilities like PODs. We propose an integer programming model that integrates the Maximal Covering Location Problem (MCLP) and includes capacity constraints. Additionally, we conducted a case study in Incheon Metropolitan City to compare the outcomes. Through this case analysis, we present the optimal subset of temporary logistics warehouses, enabling the development of an optimal location-distribution plan. The study holds three main implications: (1) it provides an optimized selection of locations that aids in the decision-making process for policies; (2) the empirical analysis using real data allows for its application in similar disaster management situations; (3) the proposed model can be utilized to determine the positioning of various public facilities 긴급물류 시설의 최적 위치는 자연재해와 팬데믹 등의 공중보건 비상 상황에서 중요성이 강조된다. 긴급물류, 조달, 분배를 포함한 효율적인 재난관리를 위해 Point-of-Dispensing(PODs) 등의 임시시설물 위치를 고려하는 것이 중요하다. 따라서 긴급물류창고 위치 결정 시, PODs의 위치를 제약조건으로 하는 최적화 방법이 필요하지만, 이러한 시각을 반영한 연구가 다소 부족하였다. 본 연구에서는 최대 커버링 입지 문제 (Maximal Covering Location Problem)을 적용하여, PODs의 위치를 매개변수로 하고 시설물의 수용력 제약조건을 추가한 정수 선형계획법 모델을 제시하였다. 또한, 인천광역시의 실제 데이터를 적용하여 일반적인 MCLP 모델과 논문에서 제시한 모델의 결괏값을 비교하고, 사례분석을 통해 최적 긴급물류창고 위치 최적해를 이용한 최적 위치-분배계획을 수립하였다. 본 연구는 재난 발생 전 행정적으로 지정된 PODs의 위치를 적용하고 상업 물류와 구분되는 재난관리 및 긴급물류의 특성을 반영하였으며, 사례분석에서는 수요 지역의 동질성을 고려한 시간 프레임 임계값을 이용하였다는 점에서 차별점이있다. 본 논문은 실제 데이터를 이용한 사례분석으로 비슷한 재난관리 상황에 적용 가능하므로 정책 결정 과정에 도움을 주었으며, 수용력 제약조건을 추가한 모델은 임시 거주 시설물 등 다양한 긴급 시설물의 위치를 결정하고 이를 지원하는 긴급물류 관리에 이용될 수 있다는 의의를 가진다.

Objectives This study aimed to review clinical studies about Korean medicine used in peroneal nerve palsy. Methods In 11 online databases (Earticle, Research Information Sharing Service, Oriental Medicine Advanced Searching Integrated System, KMbase, Korean Traditional Knowledge Portal, National Digital Science Library, MEDLINE/Pubmed, Ebscohost, Cochrane CENTRAL, EMBASE, China National Knowledge Infrastructure), we searched clinical studies about Korean medicine. Among the studies that we've searched, we excluded the studies that are not related to Korean medicine, case reports, randomized controlled trials and retrospective studies. As a result, 16 case studies and 1 randomized controlled trial are included. Results Total number of patients was 123. In these studies, acupuncture (100%), herbal medicine (58.8%), pharmacopuncture (58.8%), Korean physical therapy (58.8%), moxibustion (41.1%), cupping (41.1%) etc. were used. In acupuncture, GB34 and ST36 were most frequently used. Most of the herbal medicines used in these studies were different. Range of movement were most frequently used in outcome measure. Conclusions In this study, we reviewed studies about Korean medicine used in peroneal nerve palsy. It was difficult to clearly determine which intervention has improved the symptom. In the future, Further clinical studies will be needed to retain the evidence for the treatment of peroneal nerve palsy. And also more randomized controlled clinical trials to prove the efficacy of Korean medicine will be needed. (J Korean Med Rehabil 2019;29(3):61-74)

The objective of this study is to assess the impacts of additional N fertilization on agricultural traits, flour characteristics, andnoodle quality of O-free, a variety known for reduced allergy effects. With increasing fertilization rates, both culm length and spike lengthshowed an increase, accompanied by a rise in grain nitrogen removal due to higher protein content in the grains. The leaf area index (LAI)reached its peak during the booting stage, while the canopy LAI peaked at 21 days after flowering (21-DAF). Although LAI of plant washigher in the treatments with additional nitrogen (N1 and N2) compared to the control (N0), there was no significant difference observedin canopy LAI. Chlorophyll fluorescence values were highest at 21-DAF and lowest at 35-DAF, regardless of the fertilizer rate. The dryweight of leaves and stems was highest at 7-DAF in N0 and N1 treatments, but at 21-DAF in N2 treatment. During grain filling, the nitrogencontent decreased in leaves and stems, while it increased in the grains. With higher fertilization rates, there was an increase in the moisturecontent, flour color value, protein content, and sedimentation value of flour, whereas the particle size of flour decreased. Dough extensibility,mixing time, and protein strength showed an increase as the fertilizer rate increased, but dough stability decreased. The control exhibitedthe highest starch gel stability and aging, while N1 had the lowest starch swelling. Cooked noodles demonstrated increased brightness, thickness,and hardness with increasing fertilizer rate, but elasticity and viscosity showed no significant changes.

Verbal Inflections in the Aspectual Field

홍수민 한국언어과학회 2022 언어과학 Vol.29 No.1

This paper investigates the verbal inflections in the aspectual field in the clause. Under Chomsky’s lexicalist-minimalist account, the tense and agreement verbal inflection is believed to be syntactically autonomous. In a similar vein, other verbal inflections like aspectual and passive forms are also treated as independent functional head. In the case of complex auxiliary constructions, the verbal inflection of auxiliary verbs consistently determines their distribution and position in the varied constructions including existential constructions, VP ellipsis, and clauses with floating quantifiers or a certain class of adverbs. Usually, a specific type of auxiliary verb does not condition its distribution and position. All the nonfinite forms of auxiliary verbs do not behave in a uniform manner. More division of the aspectual field may be a viable option on the basis of irrefutable differences between the -en form been and the -ing form being in their distribution in relation to adverbs and the possibility of ellipsis.

In this paper, we used Helmholtz solver based on 3D finite element method to quantitatively analyze the effects of change of gain, time delay and time delay spread, which are the main variables of flame transfer function, on combustion instability in gas turbine combustor. The effects of the variable of flame transfer function on the frequency and growth rate, which are the main results of combustion instability, were analyzed by applying the conventional heat release fluctuation model and modified one considering the time spread. The analysis results showed that the change of gain and time delay in the same resonance mode affected the frequency of the given resonance modes as well as growth rate of the feedback instability, however, the effect of time delay spread was not relatively remarkable, compared with the dominant effect of time delay.

Passive Constructions with Passive Light Verbs in Korean

홍수민 현대영미어문학회 2018 현대영미어문학 Vol.36 No.4

“Passive Constructions with Passive Light Verbs in Korean.” The Journal of Modern British & American Language & Literature 36.4:261-82. This paper is the study of passives with passive light verbs in Korean. The main goal in this paper is to explore the properties of so-called verbal nouns and unique characteristics of the passive light verbs in passives. There is no consensus on the categorial status of verbal nouns in the literature because they behave ambiguously especially with respect to their syntactic category. Sometimes they pattern with regular nouns and other times they pattern with regular verbs. They are shown to have argument-taking capabilities and also verbal case assignment abilities when they are coupled with a temporal/aspectual dependent noun. The VN alone is not solely in charge of assigning verbal case. This tightly tied in with the suggestion that the VN should be taken to be an underspecified category. Passive light verbs may impose selectional restriction on its arguments. The strength of semantic constraints on their arguments may differ in degree. A violation of selectional restriction can result in ill-formedness or semantic awkwardness. (University of Seoul)

Background : The aim of this study was to investigate the relationship between temporomandibular disorder and occlusion, emotional factor. Through this study, it attempted to provide proper recognition of diagnosis and therapy of temporomandibular disorder Methods : A Total of 154 subjects with permanent dentition were included in this study. Internal derangement without reduction (n=82) were selected as experimental group and symptom-free subjects (n=72) were included as control group by means of clinical examination, radiographic examination and questionnaire. Investigation of morphological occlusion in each group and SCL-90-R questionnaire was performed to compare both groups Results : It was found that internal derangement without reduction was more prevalent in the individuals who have some occlusal features of open bite and deep bite. In SCL-90-R analysis, it had been observed significant relation between 5 indices (som, oc, dep, anx, par) and internal derangement. And depression, anxiety, obsessive-compulsive were more prevalent to female than male in experimental group. Conclusion : There was significant correlation between some occlusal variables (open bite, deep bite) and internal derangement of TMJ. Some emotional factor (depression, anxiety, obsessive-compulsive, paranoid ideation) was found to be related to internal derangement. Female seemed to be affected by emotional factors more than in male as well.
