Currently, Changwon-si is gathering a lot of technical information to develop hydrogen electric vehicle technology as a future regional flagship industry to discover it as a promising technology in the future. Collecting technical information has many problems in terms of time and cost due to classification methods, technical trends, and similar technologies. Therefore, a systematic classification of technical information and a method for easily deriving technical trends are needed. In this paper, we analyzed the blank technology and promising technology trends for the future core industries of the region through the method of measuring the growth rate of patents and the frequency of patent application through the patent indicators.

A Portrait of the “Evil Heart” in 4 Ezra

박장훈 (재)대한성서공회 성경원문연구소 2022 성경원문연구 Vol.- No.50

Conscious of the need to study 4 Ezra on its own right before utilizing it to illuminate Paul and other New Testament documents, we explored 4 Ezra with particular reference to the notion of an “evil heart.” Written in the wake of the Destruction, 4 Ezra identifies the “evil heart” as the cause of Israel’s downfall, characterizing it five ways. First, it originates from the time of Adam, being formed in Adam before his fall, and becoming universally powerful in Adam’s descendants as a result of Adam’s transgression. Second, the “evil heart” is powerful enough to produce sins despite of the presence of Israel’s law, as is clear from Israel’s failure to resist the “evil heart” with the law. Third, the “evil heart” has universal potency except for a small number of Israel’s remnants who are helped by God to resist its power. Fourth, the “evil heart” is also responsible for universal human mortality and brings those under its power to miserable postmortem existence and tragic eschatological separation from God. Fifth, the remnant who are immune to the operation of the “evil heart” are considered a new Adamic people to inherit the new world and live in the new age whereas the rest of Adamic humanity remain bound within the present world. Any who attempts to compare 4 Ezra’s notion of the “evil heart” with Paul’s notion of sin or any other supposed New Testament equivalent needs to take into account these findings.

Roll-to-Roll Coating Technology and Its Applications: A Review

박장훈,신기현,이창우 한국정밀공학회 2016 International Journal of Precision Engineering and Vol.17 No.4

Roll-to-roll (R2R) coating technologies, with their advantages in terms of high throughput and environmental friendliness, are expected to be used at various industrial sites. Thin-film and thick-film forming can be conducted by various techniques that can be installed with R2R systems including dip coating, knife-over-edge coating, slot-die coating, direct- and micro-gravure coating, and spray coating. In this review, coating techniques are introduced from the perspective of process optimization along with examples of applications. Moreover, R2R web handling is also covered for its relationship with the coating process. Process conditions are obtained by presenting the mathematical modeling of each process and a real coating window is presented with surveyed data. Applications of coating technologies focus on printed electronic devices because of their ability to use soluble materials. State-of-art R2R vacuum coating and lab-scale coating without R2R are not discussed in this review. This summary of R2R coating techniques and applications aims to give guidelines for operation and long-term prospects for advanced coating manufacturing.

항적자료를 활용한 항공기 연료 소모량 추정 및 정확도 분석

박장훈,구성관,백호종,Park, Jang-Hoon,Ku, Sung-Kwan,Baik, Ho-Jong 한국항공운항학회 2014 한국항공운항학회지 Vol.22 No.4

As global warming becoming an environmentally serious issue, more attention is drawn to fuel consumption which is the direct source of green house gas emission. The fuel consumption by aircraft operation is not an exception. Motivated by the societal and environmental context, this paper explains a method for estimation of aircraft fuel consumed during their flights as well as the computational process using real flight track data. Applying so-called 'Total Energy Model' along with aircraft specific parameters provided in EUROCONTROL's Base of Aircraft Data (BADA) to aircraft radar track data, we estimate fuel consumption of individual aircraft flown between Gimpo and Jeju airports. We then assess the estimation accuracy by comparing the estimated fuel consumption with the actual one collected from an airline. The computational results are quite encouraging in that the method is able to estimate the actual fuel consumption within ${\pm}6{\sim}11%$ of error margin. The limitations and possible enhancements of the method are also discussed.

Polarity-tuned Gel Polymer Electrolyte Coating of High-voltage LiCoO_2 Cathode Materials

박장훈,이윤성,조주현,김종수,심은지,이상영 한국전기화학회 2011 한국전기화학회지 Vol.14 No.2

We demonstrate a new surface modification of high-voltage lithium cobalt oxide (LiCoO_2) cathode active materials for lithium-ion batteries. This approach is based on exploitation of a polarity-tuned gel polymer electrolyte (GPE) coating. Herein, two contrast polymers having different polarity are chosen: polyimide (PI) synthesized from thermally curing 4-component (pyromellitic dianhydride/biphenyl dianhydride/phenylenediamine/oxydianiline) polyamic acid (as a polar GPE) and ethylene-vinyl acetate copolymer (EVA) containing 12 wt% vinyl acetate repeating unit (as a less polar GPE). The strong affinity of polyamic acid for LiCoO_2 allows the resulting PI coating layer to present a highly-continuous surface film of nanometer thickness. On the other hand, the less polar EVA coating layer is poorly deposited onto the LiCoO_2, resulting in a locally agglomerated morphology with relatively high thickness. Based on the characterization of GPE coating layers, their structural difference on the electrochemical performance and thermal stability of high-voltage (herein, 4.4 V) LiCoO_2 is thoroughly investigated. In comparison to the EVA coating layer, the PI coating layer is effective in preventing the direct exposure of LiCoO_2 to liquid electrolyte, which thus plays a viable role in improving the high-voltage cell performance and mitigating the interfacial exothermic reaction between the charged LiCoO_2 and liquid electrolytes.

An Analysis of Pinned Edge Layer of Slot-Die Coated Film in Roll-To-Roll Green Manufacturing System

박장훈,김성용,이창우 한국정밀공학회 2018 International Journal of Precision Engineering and Vol.5 No.2

Roll-to-roll slot-die manufacturing of soluble materials with a uniform layer is a critical step in realizing low-cost and eco-friendly printed electronics for solar cells and batteries. This study presents an analysis of the lateral thickness of a coated layer that consists of a fluid with a high viscosity produced by using a slot-die roll-to-roll system with specific attention focused on a pinned edge phenomenon exhibited in the coated layer. A solution viscosity of 832 mPa·s is used and includes relatively high capillary numbers in the experiment in the range of 0.47–3.47. The purpose of the study included analyzing various forces around the coating nozzle and determining the correlation between forces by using dimensionless numbers. Computational fluid dynamics analysis and experiments were performed to obtain various parameters in terms of these dimensionless numbers. The experimental results suggest that the pinned edge should be reduced below 10% by reducing the coating gap parameter that represents the gravity forces.
