This paper presents a facial expression recognition based on Gabor wavelets that uses a fuzzy C-means(FCM) clustering algorithm and neural network. Features of facial expressions are extracted to two steps. In the first step, Gabor wavelet representation can provide edges extraction of major face components using the average value of the image's 2-D Gabor wavelet coefficient histogram. In the next step, we extract sparse features of facial expressions from the extracted edge information using FCM clustering algorithm. The result of facial expression recognition is compared with dimensional values of internal stated derived from semantic ratings of words related to emotion. The dimensional model can recognize not only six facial expressions related to Ekman's basic emotions, but also expressions of various internal states.

In this paper we introduce and study the lattice paths for which the horizontal step is allowed at height $h{\geq}0$, $h{\in}{\mathbb{Z}}$. By doing so these paths generalize the heavily studied weighted lattice paths that consist of horizontal steps allowed at height zero only. Six q-series identities of Rogers-Ramanujan type are studied combinatorially using these generalized lattice paths. The results are further extended by using (n + t)-color overpartitions. Finally, we will establish that there are certain equinumerous families of (n + t)-color overpartitions and the generalized lattice paths.

The warm deep drawability in square cup drawing is investigated about a newly developed high-strength steel sheet with retained austenite which is transformed into martensite during forming. For this investigation, six steps of temperature ranges, from room temperature to $250^{\circ}C$, and five kinds of drawing ratio, from 2.2 to 2.6 were adopted. As a result the maximum drawing force and the maximum drawing depth were affected by the elevated temperatures, and the more stable thickness strain distribution was observed to the elevated temperatures. But blue shortness happened over $200^{\circ}C$. The FEM analysis using the LS-DYNA code is adopted to compare the experimental results with the analytical results for thickness strain distribution.

According the high growth of Korean economy, there are many changes in our life recently. As life quality is improved, the standard of construction is strengthen and subdivision. However, in many steps through which it passes until a building is planned, designed, constructed and completed, there are lots of problems among the law related architecture. Especially, there are many statutes which must be checked related to building permits and much wastes time and money in review because of overlapping laws related architecture. Furthermore, there are limitation of computerization and shortage of human power of administration in architecture. In this study, we propose six improvement programme of administration service in architecture. Through these program, civil applications like housing and economic condition could be improved consistently.

For development of teaching model for observational experiment and the major contents of science education guide books published for secondary school teacher in America, the actual survey to the secondary schools and the investigation of science education guide were carried out. The results were summarized as follows. 1. The major concepts of contents in science education books are constituted of introduction(9.67%), ability(8.94%), activity(6.61%), curriculum(11.61%), instruction planning(5.25%), instruction strategy(l7.74%), materials and facilities(1O.97%), evaluation(8.62%), society and community(l0.55%), guidelines(4.76%), practice(3.54%), and index(1.74%). 2. The constitution of multimedia teaching model for observational instruction was developed and arranged in order of six steps as observation, materialization, broad understanding, advanced study, application, and synthesis. This model was thought as the most effective for the achievement of the instructive goal for observational unit and others.

The purpose of this paper is to construct a CIDEAR (Cross Impact Data Envelopment Analysis Assurance Region) model which evaluates proposed R&D projects considering cross impacts among them and selects them to utilize R&D resources effectively as well as to maximize effectiveness of investments. For this purpose, the following six steps are designed as the main procedure. $\lceilDecision\;Theory\;&\;Evaluation\;Model\rfloor$, $\lceilAR\;Decision\;&\;Evaluation\;Model\rfloor$, $\lceilResource\;&\;Performance\;Analysis Model\rfloor$, $\lceilCross\;Impact\;Assumption\;Model\rfloor$, $\lceilpriority\;Oder\;Decision\;Model\rfloor$, $\lceilEfficiency\;Cause\;Analysis\;Model\rfloor$. $\lceilCIDEAR\rfloor$ model can deal with the affairs of R&D projects having the characteristics of mutual independence as well as mutual dependence. Hence it is possible to evaluate and select R&D projects more accurately than any other models.

Language learning involves linguistic environments around the learner. So the variation in training input to which the learner is exposed has been linked to their language learning. We explore how linguistic experiences can cause differences in learning linguistic structural features, as investigate in a probabilistic graphical model. We manipulate the amounts of training input, composed of natural linguistic data from animation videos for children, from holistic (one-word expression) to compositional (two- to six-word one) gradually. The recognition and generation of sentences are a "probabilistic" constraint satisfaction process which is based on massively parallel DNA chemistry. Random sentence generation tasks succeed when networks begin with limited sentential lengths and vocabulary sizes and gradually expand with larger ones, like children's cognitive development in learning. This model supports the suggestion that variations in early linguistic environments with developmental steps may be useful for facilitating language acquisition.

When a ship is sailing on the sea, she has the six-degrees of freedom of motion. It means that she meets a lot of dangerous situations. Especially, when the VLCC is travelling in irregular sea, the slamming, the deck-wetness and the propeller racing are occured with the sea state she is on. These are the representative steps that a heave-to and a scudding are used for a ship building , but for a predominance in both. The author intends to clarify this problem theoretically. The methods of statistical calculation are based with the ITTC spectral formulation and with the assumption that the wave height histogram follows the Rayleigh distribution. In this study, the author gives an attention on the relative bow motion to a wave in the irregular sea. It is verified that the relative diplacement at the bow to sea level in the following sea is less than that in the head sea. It is confirmed that, therefore, one have to sail with scudding when he is threatened to heave-to at a rough sea. But he must bear the propeller racing in mind in the cases.

An intracellular protease form cells of Pseudomonas carboxydovorans DSM 1227 grown on carbon monoxide was purified 57-fold in six steps to homogeneity with a yield of 4.3% using azocoll as a substrate. The molecular weight of the enzyme was determined to be 150,000. Sodium dodecyl sulfate-gel electrophoresis revealed the purified enzyme to be a dimer with two identical subunits of molecular weight 72,000. The enzyme was stimulated by $Mg^{2+}$ but was inhibited completely by $Cd^{2+}$ $Fe^{2+}$ $Hg^{2+}$, and $^Zn{2+}$ The enzyme activity was also inhibited by EDTA, EGTA, phenylmethylsulfonyl fluoride, and phenyl glyoxal, but was increased by 1-ethyl-3(dimethyl aminopropyl fluoride, and phenyl glyoxal, but was increased by 1-ethyl-3(dimethyl aminopropyl)carbodiimide, iodoacetamide and dithiothereitol. The optimal pH and temperature for the enzyme reaction were found to be 7-8 and 50.deg.C, respectively. Casein and bovine serum albumin were hydrolyzed by the enzyme, but carbon monoxide dehydrogenase was not.

Mega-Y project is very important for a company to gain a competitive advantage in markets or to achieve drastic change in the internal processes. It stems from the company strategy and annual management goals or key performance measures, and is proceeded by the cross-functional team. This paper presents the success factors and implementation process of the Mega-Y projects. The implementation process is presented in 5 steps, including project selection, cross-functional team building, establishment of the master plan, development and execution of sub-projects, and project completion. A case study on the cost reduction project of aircraft development is presented to help for the practitioners to deploy the implementation process introduced in this paper.
