Culture is way of life. And a culture is based on the view of nature and humun being. Korea has many kinds of tradition. Out of them, Korean character Hangul, food and medicine have been succeeded as they were in old days. So I tried to induce Korean view of nature and human being from those traditions. The common principle induced from them is Yin-yang and five elements. Yin-yang and five elements is away to cognize nature by Korean people. That means Yin-yang is thought to be the principle of nature. Nature is what life is born or produced. And mankind is a part of nature. Thus Yin-yang and five elements works on mankind in the same way as they do on nature. Mankind is born and grows on the earth. So human body consists of four, parts of the earth, which are light, air, water and soil. It is essential for human being to maintain balance and harmony in nature with nature and as nature.

The error function can be calculated based on the Simpson method through a subroutine program. An integration program by FORTRAN language was made for diffusion equations of extended source with infinite extent and limited extent. The results on some alloying elements such as C, Co, Cr, Mn, Mo, Ni and V's diffusion in iron, showed the diffusion distance for Ni and Mo can only be $1{\sim}3\;{\mu}m$ and more distance for Co at common sintering temperature of $1120^{\circ}C$. To refine the particle size of the added elements down to a scale of micrometers is an effective way to get homogeneous distribution.

As the era of the 4th Industrial Revolution enters, the importance of software safety is increasing, but related systematic educational curriculum and trained professional engineers are insufficient. The purpose of this research is to propose the high priority elements for the software safety education program through needs analysis. For this purpose, 74 candidate elements of software safety education program were derived through contents analysis of literature and nominal group technique (NGT) process with five software safety professionals from various industries in South Korea. Targeting potential education participants including industrial workers and students, an on-line survey was conducted to measure the current and required level of each element. Using descriptive statistics, t-test, Borich needs assessment and Locus for focus model, 16 high priority elements were derived for software safety education program. Based on the results, suggestions were made to develop a more effective education program for software safety education.

In Teaching Chinese as a Foreign Language, phoneme-based pronunciation teaching such as tone, consonants, vowels is the most common teaching methods. Based on main character of Chinese grammar: 'lack of morphological change' in a narrow sense, was proposed by Lv Shuxiang and Zhu Dexi, I designed 'Communicative oriented Chinese pronunciation teaching method'. This teaching method is composed of seven elements: one kind is the 'structural elements': phoneme, word, phrase, sentence; another kind is the 'functional elements': listening, speaking and translation. This pronunciation teaching method has four kinds of practice methods: 1) phoneme learning method; 2) word based pronunciation practice; 3) phrase based pronunciation practice; 4) sentence based pronunciation practice. When the teachers use these practice methods, they can use the dialogue and Korean-Chinese translation. In particular, when the teachers use 'phoneme learning method', they must use Korean and Chinese phonetic comparison results. When the teachers try to correct learner's errors, they must first consider the speech communication.

In this paper, we consider a class of inhomogeneous random intersection graphs by assigning random weight to each vertex and two vertices are adjacent if they choose some common elements. In the inhomogeneous random intersection graph model, vertices with larger weights are more likely to acquire many elements. We show the Poisson convergence of the number of induced copies of a fixed subgraph as the number of vertices n and the number of elements m, scaling as $m={\lfloor}{\beta}n^{\alpha}{\rfloor}$ (${\alpha},{\beta}>0$), tend to infinity.

Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES) is widely used for the determination of trace elements in geological samples in Iran. In this paper, we have calculated the detection limits of neutron activation analysis (NAA) for some of the common elements in such samples utilizing the ORIGEN and MCNP codes and verified the simulations using the experimental results of three soil standard reference materials, namely, G02.SRM, G18.SRM, and G28.SRM. The results show that while the detection limit of ICP-AES method is usually in the mg/kg range, it is represented to the ${\mu}g/kg$ range for most of the elements of interest using the NAA method, and the simulations can be verified in a tolerance range of 20%.

The applications of intangible cultural heritage in China have encountered development bottlenecks due to poor user experience. In this paper, we begin to study the reasons why the user experience is not good, and to study design methods that enhance the user experience through the theory of five-factor model. Through literature study and comparative study of contestants, this paper investigates the advantages and disadvantages of their interaction design and summarizes the common problems. Next, a survey of these user populations will be conducted to find some design elements that affect the user experience. Finally, through empirical research, the design elements are incorporated into the theory of user experience modeling and case studies demonstrate that the application of the design elements is beneficial to improving the user experience.

The isolate HL-15 of Bacillus thuringiensis had common biochemical characteristics of the 23 serovarieties of B. thuringiensis. The isolates formed round endotoxin crystals which killed insect larvae, showed independent serological H antigen to the 23 serotypes, and contained two defferect DNA elements with over 100 Mdaltons of molecular weights.

As the technology advances, the product design process is also being complicated. These days, it is common for engineers to consider socio-psychological factors as well as technological elements in the design process. In this work, I will explain why and how engineers make allowances for human factors in developing and designing technological products.

운동 중첩에 의해 배경의 유도 요소들이 차례로 사라질 때 유도 요소들이 사라지는 순서와 이들이 이루는 각도는 직선적 윤곽의 방위가 존재할 수 있는 범위를 한정시켜 준다. 이러한 제약 범위의 시간적 통합에 의해 운동중첩에 의한 윤곽 추출 과정을 설명하는 공통 제약 범위 모형을 제안하고 그것의 타당성을 검증하기 위해 다섯 편의 실험을 수행하였다. 실험 결과 윤곽 방위에 대한 공통 제약 범위 각의 크기가 작을수록 윤곽 방위 지각의 정확율이 높은 것으로 나타났다. 운동 중첩 요소의 수를 증가시키거나 요소들 사이의 거리를 변화시키더라도 제약 범위가 일정하다면 윤곽지각의 정확율은 높아지지 않는 것으로 나타났다. 이러한 실험 결과는 윤곽 방위에 대한 공통 제약 범위 모형을 지지해주는 것으로 해석될 수 있으며 운동 중첩에 의해 윤곽을 지각하는 과정에 배경 텍스쳐의 밀도 자체보다 운동 중첩에 의해 결정되는 공통 제약 범위 각의 크기가 더 중요한 역할을 할 수 있다는 것을 시사한다.
