송재익 ( Song¸ Jae Ik ) 한국군사학회 2021 군사논단 Vol.108 No.-

On watching KBS drama ‘Jing Bi Lok’ in 2015, I arise to read 《Jing Bi Lok》(written by You Sung Yong) in mind, and then have read 《Gan Yang Lok》(written by Kang Hang). Two books were written on our national suffering history in 1st and 2nd Chosun-Japanese War (1592-1598) I knew international politics of North East Asia about the end of 16 century, and strategy and tactics, political leadership, weapon system of Chosun Dynasty. Through reading 《Jing Bi Lok》and 《Gan Yang Lok》on 1st and 2nd Chosun-Japanese War, I made history view new, and happened to know a deep meaning on national and security view. Lesson learn and suggestions to give contemporary ours through 《Jing Bi Lok》and 《Gan Yang Lok》are as follows. After we find a exact change of international politics in North East Asia, we have to establish and conduct a national security strategy and military strategy. Present Korea is not of Chosun of 16 century. As a smart dolphin beyond a hedgehog, Korea have to prepare the future, developing and enforcing education training and doctrine on combined operations and joint operations, and go abreast developing weapon system and spirit power. For achieving the Unity of Korea, we have to a changed idea on prisoner and we need to change the paradigm especially for North Korean People and a prisoner of Korean Peoples Army during Stability Operations.

Gender and Age Differences in Triple Media Usage Related to Outdoor Apparel Purchases

( Jaeik Yoon ),( Hanna Kim ) 한국의류학회 2015 한국의류학회지 Vol.39 No.5

This study defines the concept of triple media and examines various marketing media that influence a consumer``s purchase of outdoor fashion brands. We explore the effects of gender and age on information searches related to outdoor fashion brands and purchase criteria related to outdoor clothing. A survey of consumers who visited stores was conducted. We targeted consumers between the ages of 15 and 50 and analyzed 764 questionnaires. The results show that triple media involve eight factors: five factors (printed ads or radio ads, campaign ads, Internet ads, TV ads, and store ads) in paid media, one factor (direct marketing) in owned media, and two factors (channels of social network services, channels of direct promotion) in earned media. Further, the evaluation/appraisal criteria of outdoor clothing consist of four attributes (practicality, promotional activities, product power, and customer service). The teenager group showed significantly low usage of campaign ads, direct marketing, and direct promotion, while the use of Internet ads is particularly high among teenagers compared to other age groups. Moreover, teenagers are least likely to rely on practicality when evaluating clothing and are most likely to value product power. Additionally, women show significantly high usage of direct marketing. In terms of the clothing appraisal criteria, women assign higher value to practicality and promotional factors than men. The theoretical and managerial implications of the findings are discussed.

Thermal Via Placement in 3D IC Interposer

Jaeik Chun,Jun Dong Cho 대한전자공학회 2010 ICEIC:International Conference on Electronics, Inf Vol.1 No.1

As the technology progresses, chip area and wire length continue to increase, causing increased interconnect delays and power consumption. Integrating several functional chips in 3D stack package leads to innovation of mobile devices. However, stacking of many chips in a 3D package leads to high heat dissipation which can causes time delay and heat failure. Our study of 3D IC thermal solution focuses on interposer. Interposers are adopted for connection of 3D chips and PCB and also used as thermal pass way through PCB. Interposer with dummy thermal via is applicable for advance heat dissipation. In this paper, we suggest cost effective thermal treatment model to reduce delay caused by thermal effect. We use dummy thermal via in interposer at critical hot-spot. The suggested model results in 7.7 percents of delay reduction on the average.

An Edge-based Method to Classify Open and Closed Eyes for Monitoring Driver’s Drowsiness

Jaeik Jo,Sung Joo Lee,Youn Joo Lee,Ho Gi Jung,Kang Ryoung Park,Jaihie Kim 대한전자공학회 2010 ICEIC:International Conference on Electronics, Inf Vol.1 No.1

Monitoring the drowsiness and inattention of a driver plays an important role in preventing car accidents. Previous researches show that many vehicular accidents in highway are caused by the fatigue due to long-time driving, inattention or dozing of a driver. To resolve these problems, we propose a method to classify open and closed eyes by analyzing horizontal edge of eye images. After initial locations of face and eyes are found by using object detection methods such as Adaboost, an edge-based method is used to extract feature from detected eye image. Then, open and closed eyes are classified by the threshold based on Bayesian rule and analysis of extracted feature. Experimental results show that open and closed eyes are reliably classified in actual vehicular environments.

Building the capacity for climate change from low carbon development and energy GIS

Jaeik LIOU(류재익) 한국환경정책학회 2010 한국환경정책학회 학술대회논문집 Vol.2010 No.10

In the midst of global emerging issues for climate change mitigation and adaptation, the concentrations on capacity building (CB) and capacity development (CD) have been seriously highlighted in recent years to tackle negative impacts of greenhouse gas emissions (GHG) and environmental degradations at the municipal and national levels. CB and CD approach to climate change would be regarded as the development or strengthening of personal skills, expertises, and relevant institutions and organizations to reduce GHG emissions and to minimize vulnerability to climate-related impacts. There are, however, still ambiguous aspects of CB and CD as to how climate change"s experts and specialists in the UNFCCC, UNE(D)P and GEF could translate multi-dimensional natures of capacities into a specific heart of carbon emission"s reduction and low carbon development without slacks or discontinuity of sustainable development. The paper expounds international views of CD in association with low carbon developments and proposes an innovative model for climate change sustainable capacity development. In addition, a technical approach to carbon emission"s reduction is creatively designed to build the capacity in sustainable low carbon development. It especially shed light on universal characteristics of mitigative and adaptive capacity for a conceptual climate change framework based on sustainable energy and carbon management system.

Necessary and Sufficrent Geometric Conditions

Jaeik Lee,Jongnyun Lee 한국산업응용수학회 2005 한국산업응용수학회 학술대회 논문집 Vol.- No.-

This Paper deals with a geometric criterion for checking the incompressibility of ∂Hk-Γ, where Hk, and Γdenotes an orientable handle body of genus k and a finite system of pairwise disjoint simple closed curves in ∂Hk. Our theorem will turn out to be very applicable for various surfaces in Hk, and give us a visual approach in detecting the incompressibility of ∂Hk-Γ. So it provides us with useful information about compressing disks for ∂Hk-Γ when ∂Hk-Γ is compressible in Hk.

Unsteady flow simulations for synthetic jets in quiescent air

Jaeik Ko,Jihyeon Park,최민석 대한기계학회 2023 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.37 No.10

Unsteady flow simulations were conducted to investigate the flow generated by a synthetic jet actuator in quiescent air. The predicted synthetic jets by 2D axisymmetric and 3D simulations were compared to each other and experimental data to check their accuracy. It was found that the 2D axisymmetric simulations were as accurate as the 3D simulations to predict synthetic jets in quiescent air. Thereafter, three different membrane profiles, namely a simple trigonometric model, a distributed load model and a concentrated load model, have been tested to determine which one is most appropriate to describe the motion of a piezoelectric disc, which was attached to a cavity and was oscillated to generate synthetic jets, using 2D axisymmetric unsteady simulations. Finally, a critical value of Mach number was found in this work for considering the compressibility of air based on the numerical simulations for synthetic jets.
