박태현 한국사회체육학회 2024 한국사회체육학회지 Vol.- No.97

Purpose: This study aims to provide practical implications and research data to enhance the economic impact of hosting marine leisure events by local governments. Method: It does so by comparing and analyzing the economic ripple effects of recently held marine leisure events and competitions. Based on this analysis, the following conclusions were drawn. Results: Firstly, the 2023 ASAF Keelboat Cup & Boryeong International Sailing Championship recorded the highest personal consumption expenditure. This can be attributed to the direct and indirect influence of the region’s representative festival, the “2023 Boryeong Mud Festival,” which took place during the same period. Secondly, an examination of the proportion by industry classification items shows that the composition ratio of retail (tourism shopping) for all three marine leisure events averaged around 5%. Thirdly, when examining the induced coefficient results for each comparison target for regional industry linkage analysis, different calculation methods were applied. If a reliable regional input-output table is not provided when quantitatively analyzing the economic ripple effects of sports events, there is a possibility of overestimation. Conclusion: This study is significant as it has provided practical implications that can address the seasonal limitations and short-term investigation constraints associated with marine leisure sports.

Polymer-waveguide Bragg-grating Devices Fabricated Using Phase-mask Lithography

박태현,김성문,오민철 한국광학회 2019 Current Optics and Photonics Vol.3 No.5

Polymeric optical waveguide devices with Bragg gratings have been investigated, for implementing tunable lasers and wavelength filters used in wavelength-division-multiplexed optical communication systems. Owing to the excellent thermo-optic effect of these polymers, wavelength tuning is possible over a wide range, which is difficult to achieve using other optical materials. In this study the phase-mask technology, which has advantages over the conventional interferometeric method, was introduced to facilitate the fabrication of Bragg gratings in polymeric optical waveguide devices. An optical setup capable of fabricating multiple Bragg gratings simultaneously on a 4-inch silicon wafer was constructed, using a 442-nm laser and phase mask. During fabrication, some of the diffracted light in the phase mask was totally reflected inside the mask, which affected the quality of the Bragg grating adversely, so experiments were conducted to solve this issue. To verify grating uniformity, two types of wavelengthfiltering devices were fabricated using the phase-mask lithography, and their reflection and transmission spectra were measured. From the results, we confirmed that the phase-mask method provides good uniformity, and may be applied for mass production of polymer Bragg-grating waveguide devices.

H. Bavinck의 『하나님의 큰 일(Magnalia Dei)』에 나타난 직분론과 한국교회

박태현 한국복음주의실천신학회 2016 복음과 실천신학 Vol.38 No.-

본 연구 논문은 건전한 신학 부재와 윤리실종의 한국교회를 갱신하기 위하여 20세기 개혁주의 신학자인 헤르만 바빙크의 교회 직분론을 한국 교회에 적용한 것이다. 16세기 칼빈 이후 계승 발전된 개혁신학을 총체적으로 체계화시킨 네덜란드의 개혁주의 신학자 헤르만 바빙크(Herman Bavick, 1854-1921)는 『하나님의 큰 일』(1931)의 제 24장 ‘봉사와 직분’(Diensten en Ambten)에서 봉사와 직분에 관한 교리를 잘 드러낸다. 바빙크는 첫째, ‘도르트 교회법’ 제 2조에 근거하여 기독교회의 네 가지 봉사, 즉 (1) 말씀 봉사자들의 봉사, (2) 교사(박사)들의 봉사, (3) 장로들의 봉사, 그리고 (4) 집사들의 봉사를 지적한다. 바빙크에 의하면 이러한 교회와 성도들의 봉사의 기초는 선지자, 제사장, 그리고 왕의 삼중직을 성취하신 그리스도의 모범적 섬김의 사역에서 비롯된다. 둘째, 바빙크에 의하면 모든 신자들의 봉사는 궁극적으로 하나님의 영광을 지향한다. 셋째, 바빙크는 요한복음 14장 12절에 근거하여 그리스도께서 지상에서 친히 감당하신 3중직 사역이 주님의 부활과 승천 이후에 교회에게 위임된 사역을 통해서 그대로 지속되고 있다고 강조한다. 이런 의미에서 교회의 모든 사역은 겉으로는 목회자와 사역자들, 그리고 신자들이 감당하지만 궁극적으로는 “그리스도 자신의 사역”이다. 이상의 세 가지 기독교회의 섬김과 봉사의 신학적인 기초, 특히 말씀 봉사와 관련하여 교회는 첫째, 능력 있는 신실한 사람이 하나님의 말씀을 전하고 가르치도록 교회의 미래 봉사자들을 세밀하게 감독하고 교육해야 할 의무가 있다. 둘째, 교회의 말씀 봉사는 반드시 직분을 수단으로 하여 시행되어야 한다. 셋째, 말씀의 봉사는 말씀을 보존하고 해설하며, 그 의미를 설명해야 한다. 성례의 봉사와 관련하여, 매주일 예배에서 성찬의 회복이 필요하다. 권징의 봉사와 관련하여, 교회의 순수성과 말씀 선포의 영적 권위를 보존하기 위한 권징의 시행이 필요하다. 자비의 봉사와 관련하여, 무너진 공교회성과 공동체성 회복을 위한 자비의 봉사가 필요하다. 결론적으로 한국교회의 갱신은 모든 목회자와 신자들이 자신들을 하나님 앞에서 그리스도를 대신하고 하나님의 영광을 위하여 성령의 능력으로 다른 사람을 섬기고 봉사하는 직분을 감당해야 한다. This paper applies the doctrine of church offices of Herman Bavinck, the 20th Dutch reformed theologian to the Korean churches in order to reform and renew the Korean churches fallen into the situation that a sound Christian theology and Christian moral has become lost. Following the 16th century reformer John Calvin and his successors, Herman Bavinck has developed and systemized reformed theology, and clearly presented the doctrine of church ministries and church offices in the chapter 24 ‘Ministries and offices’ of Magnalia Dei (1931). First of all, Bavinck points out four sorts of ministries on the basis of the article 2 of ‘canon of Dordt’, that is (1) the ministry of preachers, (2) the ministry of teachers(doctors), (3) the ministry of presbyters, and (4) the ministry of deacons. According to Bavinck, these ministries are based on the example of Christ’s ministry, achieved in His threefold ministry of prophet, priest, and king. Secondly, Bavinck asserts that the ministry of all believers is ultimately aimed for the glory of God. Thirdly, based on John 14:12, Bavinck stresses that the threefold ministry of Christ achieved in His earthly ministry still continues through the ministry of the Church after Christ’s resurrection and ascension. In this respect, all the ministry of the Church is performed by ministers and workers, and believers, yet is eventually “the ministry of Christ Himself.” In terms of the ministry of the Word, the Church has three responsibilities. Firstly, the Church has duty to oversee and educate future ministers so that they might be able and faithful ministers and should to teach and proclaim the word of God. Secondly, the ministry of the word must be administered be means of the office. Thirdly, the ministry of the word should keep the word and explain the meaning. Concerning the ministry of sacraments, the Lord’s supper should be administered every worship on Sundays. Concerning the ministry of discipline, the discipline should be rightly performed for the sake of purity of Church. Concerning the ministry of mercy, it should be exercised for the recovery of catholicity which is fallen in Korea. In conclusion, for the renewal of Korean Church all ministers and believers should work instead of Christ before God and should serve other people by the power of the Holy Spirit for God’s glory.

개량 Al-6.5Si 합금의 미세조직, 인장 및 충격 인성에 미치는 합금 원소 첨가의 영향

박태현,백민석,윤상일,김진평,이기안 한국소성∙가공학회 2020 소성가공 : 한국소성가공학회지 Vol.29 No.3

Low-cost alloying elements were added to a modified Al-6.5Si alloy and its microstructure, tensile and impact toughness properties were investigated. The alloying elements added were Mg, Zn, and Cu, and two kinds of alloy A (Mg:0.5, Zn:1, Cu:1.5 wt.%) and alloy B (Mg:2, Zn:1.5, Cu:2 wt.%) were prepared. In the as-cast Al-6.5Si alloys, Si phases were distributed at the dendrite interfaces, and Al2Cu, Mg2Si, Al6 (Fe,Mn) and Al5 (Fe,Mn)Si precipitates were also observed. The size and fraction of casting defects were measured to be higher for alloy A than for alloy B. The secondary dendrite arm spacing of alloy B was finer than that of alloy A. It was confirmed by the JMatPro S/W that the cooling rate of alloy B could be more rapid than alloy A. The alloy B had higher hardness and strength compared to the values of alloy A. However, the alloy A showed better impact toughness than alloy B. Based on the above results, the deformation mechanism of Al-6.5Si alloy and the improving method for mechanical properties were also discussed.

박태현,오민철,Guanghao Huang,김태언 한국광학회 2017 Current Optics and Photonics Vol.1 No.3

A wavelength filter based on a polymer Bragg reflector has received much attention due to its simplestructure and wide tuning range. Tilted Bragg gratings and asymmetric Y-branches are integrated to extractthe reflected optical signals in different directions. To optimize device performance, design procedures arethoroughly considered and various design parameters are applied to fabricated devices. An asymmetricY-branch with an angle of 0.3° produced crosstalk less than -25 dB, and the even-odd mode couplingwas optimized for a grating tilt angle of 2.5°, which closely followed the design results. Through thisexperiment, it was confirmed that this device has a large manufacturing tolerance, which is important formass production of this optical device.

PURPOSES : High concentrations of particulate matter (PM) are emitted or generated from vehicle emissions in urban roads with dense transient populations. To reduce the effect of PM emission on bus stop users at roadsides, a plan to reduce PM emitted from the roadside must be devised. In this study, an atmospheric environment at a roadside is simulated in a large-scale environment chamber, and a test for reducing PM around the bus stop is conducted by installing a bus stop adapted to a PM reduction system. METHODS : Exhaust gas is injected into the experimental and reference chambers using diesel and gasoline vehicles for roadside airquality simulations. The two vehicles are operated in an idle state without an acceleration operation to emit exhaust gas uniformly, and the initial conditions are achieved by injecting car emissions for approximately 40 min. The initial condition is set to 1 ppm of NOx concentration in the environment chamber. Between the two environment chambers, a bus stop adapted to the PM reduction system is installed in the experimental chamber to conduct a PM reduction experiment pertaining to the air quality around the roadside. The experimental progress is set as the start time of the experiment based on the time at which the initial conditions are achieved; simultaneously, the PM reduction system in the experimental chamber is operated. After the simulation is commenced, the PM concentration, which changes over time, is measured using a high-resolution time-of-flight aerosol mass spectrometer (HR-ToF-AMS) without additional injection of car emissions or pollutants. The HR-ToF-AMS measures the chemical composition of non-refractory PM1.0 (NR-PM1.0) in real time. RESULTS : The NR-PM1.0 compound (organic aerosol (OA), NO3 -, SO4 2-) increases by 160% compared with the simulated initial concentration up to T90min in both environmental chambers; this is speculated to be due to secondary formation. The reference chamber indicates a slight decrease or a steady-state after T90min, whereas the experimental chamber indicates a gradually decrease as the experiment progresses. The bus stop adapted to the PM reduction system reduces the amount of black carbon in the experimental chamber by 37% at 200 min. This implies that the PM emitted from the roadside is filtered via the PM reduction system installed at the bus stop, and cleaner air quality can be provided to passengers. CONCLUSIONS : The PM reduction system evaluated in this study can be detached from and attached to the outdoor billboard of a bus stop. Since it adopts air filtration technology that uses a high-efficiency particulate air filter, it can be maintained and managed easily. In addition, it can provide an atmospheric environment with reduced PM emission to passengers as well as provide a better air-quality condition to passengers waiting for public transportation near roadsides.
