The purpose of this paper is to consider Jannah in Islam focused on its description and qualification of its people through the Quran and Hadith.The point I want to make is that Jannah is very similar to paradise in the Christianity. Also the sings of the last day(Yawm Al-Dīn), in the terms of the Qur’an and Hadith, focused on occurrence of the natural disasters which the mankind has not experienced throughout history. As for the description of Jannah, it is described as the most beautiful place which cannot be compared in this materialistic age. But it seems strange for the researcher that some of Jannah compositions were built from the material substances of this world and the people of Jannah eat some fruits that has exited in this world. So this requires some further explanation by Islamic theologians in the future. To be a people of Jannah, it is very important for muslim to perform two parts; the faith and practice. Above all, the number of prostration before Allah as Salat is a barometer for the people who need to be saved because they frequently repent of their sins. In the future, it should be added the explanation of Jannah’s life in more detail.

In this study, the analytical realization of coupled system in bearing was introduced using the times series identification and spectrum analysis, which was compared with conventional PET spectrum. Also, the numerical responses of second order system, which is coupled, were solved using the numerical calculation of Runge-Kutta-Gill method. After numerical analysis, the displacement, velocity and acceleration were acquired. Among them, the response of displacement was used for the analysis of time series spectrum. Among several time series, the ARMAX algorithm was proved to be appropriate for the spectrum analysis of the coupled system. Using the separated response of 1st and 2nd mode, the mode was calculated separately. And the responses of mixed modes were also analyzed for calculation of the mixed modes in the coupled system.

사우디아라비아의 공서양속(公序良俗)준수에 관한 연구 : 시행령과 위반사항을 중심으로

김종도(Kim, Jongdo) 한국아랍어아랍문학회 2020 아랍어와 아랍문학 Vol.24 No.2

사우디의 공서양속준수에 관한 시행령은 관광개방정책으로앞으로 많은 외국인이 방문할 것으로 예상되기 때문에 이에대비하여 사우디의 가치를 지키고 종교전통과 정서를 지키고자2019년 4월에 제정되어 2019년 9월 27일부터 시행하게 되었다. 이 시행령의 10개 조항 가운데 단 제3~6조에서만 공서양속에관한 포괄적인 내용을 다루고 있어 앞으로 사우디 사회에서발생하게 될 다양한 시행령의 공서양속 위반들은 어떻게대처할지 문화적 충돌이 일어날 가능성도 있다. 현재 위반유형을19가지로만 분류하고 있어 세계화와 인적 교류가 빈번하면서발생할 위반유형 이외의 것들을 규제할 현재 시행령이개정되거나 아니면 보다 상세히 공서위반 유형이 제시되어야하므로 하위범주인 시행규칙 제정이 될 가능성도 있다. The article aims to study the public decency regulation of Saudi Arabia. As we know, Saudi society has already provided a mechanism to regulate the social order or good manners by religious precepts. It seems that the main reason for the enactment of this regulation is to be a measure to avoid harming traditions, emotions, and customs. The enactment of the public decency regulation of the Saudi Arabia adopts only fine system in terms of edification rather than punishment for criminals and imposes the highest fines for indecent behavior, which can be seen as an effort to protect areas related to the performance due to the influx of foreign culture. Originally in Islam, the act of destroying public order or public morals was a personal act, and the judge was able to judge according to his own conscience (تعزير ,Ta’zīr). Along with the implementation of this regulation, Saudi society is now expected to change flexibly from a rigid atmosphere by placing the public sector in the realm of misdemeanors.

자힐리야 시대의 아랍인의 삶 연구

김종도 ( Jongdo Kim ) 사단법인 아시아문화학술원 2021 인문사회 21 Vol.12 No.1

본 연구의 목적은 이슬람 이전 시대인 자힐리야 시대(무지의 시대)의 아랍인들의 삶에 대한 연구이다. 이 논문은 그간의 연구가 자료부족으로 ‘시가문학’ 연구에 치우친 점을 벗어나 자힐리야 시대의 아랍인의 일상생활과 가장 밀접한 모티프들인 종교, 여성, 부족 사회에 초점을 두고 이를 토대로 아랍인들의 삶의 원형을 살펴보았다. 본 논문을 통하여 자힐리야 시대의 아랍인들의 삶도 타 문명권의 사람들과 마찬가지로 나약한 인간의 본성에 기인하여 종교에 의지해왔음을 알 수 있었으며 여성들에 대하여 기존의 대부분의 연구들은 여성이 남성에 비하여 모두 낮은 지위에 있었다고 주장하지만 본 연구를 통하여 일부 고위층 여성들의 권위는 높았으며 명예를 누렸음을 알 수 있었다. 크고 작은 전쟁으로 점철된 자힐리야 시대의 혈연중심의 부족사회는 그 후에 이슬람이 평화와 형제애를 모토로 삼는 좋은 교훈이 되었음을 알 수 있었다. 이 논문의 의의는 자힐리야 시대의 삶이 이슬람 출현의 자양분이 되었다는 점을 밝힌 점이다. The purpose of this article is to study the lives of Arabs in the pre-Islamic era of the Jahiliya period (Ignorance period). This article focuses on the motifs most closely related to the daily lives of Arabs in the Jahiliya period, such as religion, women, and tribal society. Based on these motifs, the researcher examined the prototypes of Arabs’ lives. Through this article, it could be seen that the lives of Arabs in the Jahiliya period, like those of other civilizations, have depended on religion due to the weak human nature. Most of the existing studies on women in the Jahilya period claim that all women were in a lower position than men, but through this study, it was found that some high-ranking women had high authority and enjoyed honor. The blood-centered tribal society of the Jahiliya era, which was marked by wars big and small, was later found to be a good lesson for Islam to take peace and fraternity as its motto. The significance of this thesis is that it revealed that life in the Jahiliya era became a nutrient for the emergence of Islam.

실시간 출력 제어를 통한 구상흑연 주철의 레이저 표면경화 특성

김종도,송무근,Kim, Jongdo,Song, Mookeun 한국레이저가공학회 2015 한국레이저가공학회지 Vol.18 No.2

This study is related to the surface hardening treatment to spheroidal graphite cast iron for die by using high power diode laser. Laser device used in this experiment is capable of real-time laser power control. This is because the infrared temperature sensor (two color pyrometer) attached to the optical system measures the surface temperature of specimen and adjusts the laser power in real time. The surface treatment was carried out with the change of heat treatment temperature at the beam travel speed 3 mm/sec. Hardened width and depth was measured and hardened zone was analyzed by micro vickers hardness test in order to research the optimum condition of heat treatment. The changes in microstructure of the hardened zone also was examined. As a result of hardness measurement and observations on microstructure of hardened zone, hardness increased over three times as compared with base metal because the martensite was formed on the matrix structure.

공조소음 저감을 위한 조합소음기 개발

공조시스템의 설계에서, 송풍기의 소음을 줄이는 것은 가장 중요한 요소 중 하나이다. 선박용 공조시스템에 널리 사용되는 축류송풍기는 작동성 및 내구성에서 많은 장점을 가지고 있지만, 저주파수대역에 위치한 날개 통과 주파수(BPF) 소음이 문제가 되고 있다. 기존의 소음기는 중중파수 및 고주파수 대역의 소음을 효과적으로 저감하지만, BPF 소음과 같은 저주파수 대역의 소음을 저감하는데 한계가 있다. 본 논문은 BPF 소음을 저감하기 위하여 사이드 브랜치 공명기를 기존 소음기에 적용하는 것을 제안한다. 소음기 내벽 및 공명기의 외벽에 설치된 흡음재와 함께 전체 주파수 대역의 소음을 제어할 수 있다. In the design of HVAC system, reducing the noise from fan is one of the most critical factors. Although axial fan which is widely used in ship HVAC system has many advantages in operability and durability, the low frequency noise called blade passing frequency (BPF) noise has always been an issue. The conventional type of silencer can effectively reduce the noise of mid-high frequency band, but it has limitations on removing noise of low frequency band such as BPF noise. This paper suggests the application of side branch resonators to the conventional silencer to reduce the BPF noise. Along with sound absorbing material installed on silencer inner wall and resonators outer wall, we can control the noise from all frequency bands.

중속 디젤엔진용 공명기 배열형 배기소음기 개발

중속 디젤엔진의 배기소음을 저감하기 위하여 배기소음기가 배기관에 설치된다. 배기관의 토출구를 통하여 방사되는 배기소음은 저주파수 대역이 지배적으로, 저주파수 대역의 소음 저감 성능을 향상시키면 전체적으로 낮은 배기소음을 실현할 수 있다. 이를 위하여 각각 다른 공명주파수를 갖는 다수의 직렬 및 병렬의 공명기 배열을 배기소음기에 적용한다. 설계된 공명기 배열은 넓은 범위의 저주파수 소음 저감 대역을 형성하여 저주파수 대역의 배기소음을 효과적으로 제어한다. 또한, 공명기 배열의 외곽에 설치된 흡음재가 중주파수 및 고주파수 대역의 소음을 저감하여 모든 주파수 영역에서 배기소음을 효과적으로 제어한다. A silencer is used in the exhaust gas pipe (EGP) to reduce the exhaust noise of a medium-speed diesel engine. The exhaust noise radiated through the discharge port of the EGP is dominated by the low-frequency band, and overall low noise can be realized by improving the noise reduction performance in the low-frequency band. To reduce the lowfrequency noise, a plurality of series and parallel resonator arrangements with different resonant frequencies are applied to the EGP silencer. The designed resonator array forms a wide range of low-frequency noise reduction bands, effectively controlling the exhaust noise in the low-frequency ranges. In addition, sound absorbing materials installed outside the resonator array reduce the noise of the middle- and high-frequency bands. The developed EGP silencer thus effectively controls exhaust noise in all frequency ranges.
