In this paper, a new synthesis method for testability of synchronous sequential circuits is suggested on an incompletely-specified state transition graph (STG) by reducing the number of redundant faults. In the suggested synthesis method, 1) a given STG is modified by adding undefined states and unspecified input transitions using distinguishable transition, 2) the STG is modified to be strongly-connected as much as possible. Experimental results with MCNC benchmark show that the number of redundant faults of gate-level circuits synthesized by our modified STGs are reduced, and much higher fault coverage is obtained.

In this paper we propose procedures to enhance testability by modifying state transition tables. In these procedures, transitions about undefined states, which are not described in state transition tables but exist in a synthesized gate level circuit, are added to a state transition table. Experimental results for MCNC benchmarks are shown.

Purpose: The purpose of this study was to address differences between mental health according to sasang constitution and ego state among college students. Methods: Data for this cross-sectional study were collected by administration of questionnaires eliciting Woo's ego state scale, QSCC II for the sasang constitution classification, and SCL-90-R for mental health to 393 college students. Analysis was performed using IBM SPSS (version 19.0). Results: The Free Child ego and Adapted Child ego differed significantly among sasang types. The ego-gram pattern of So-eum type exhibited the N pattern (Nurturing Parent (NP)>Adapted Child (AC)>Adult (A)>Free Child (FC)>Critical Parent (CP), AC-high type), however, the ego-gram pattern of other constitution types showed the M pattern (NP>FC>A>AC>CP). No statistically significant differences in mental health were observed among sasang types, however, among ego states, AC and CP showed negative correlation with mental health status. Between So-eum type and So-yang type, AC was the factor predicting mental health. Between Tae-eum type and undefined type, AC and CP were factors predicting mental health. Conclusion: These findings suggest that sasang constitution could be an important factor in understanding the ego state and mental health status. We conclude that sasang constitution should be considered in interpretation of mental health status presentation in clients.

In this study, mathematical analysis is conducted by focusing to the 'size' of the 'point' and the 'line'. The textbook descriptions of the 'point' and the 'line' in the geometry content area of middle school mathematics 1 by the 2015 revised Korean mathematics curriculum and US geometry textbooks were compared and analyzed between. First, as a result of mathematical analysis of' 'the size of a point and a segment', it was found that the mathematical perspectives could be different according to 1) the size of a point is based on the recognition and exclusion of 'infinitesimal', and 2) the size of the segment is based on the 'measure theory' and 'set theory'. Second, as a result of analyzing textbook descriptions of the 'point' and the 'line', 1) in the geometry content area of middle school mathematics 1 by the 2015 revised Korean mathematics curriculum, after presenting a learning activity that draws a point with 'physical size' or line, it was developed in a way that describes the 'relationship' between points and lines, but 2) most of the US geometry textbooks introduce points and lines as 'undefined terms' and explicitly states that 'points have no size' and 'lines have no thickness'. Since the description of points and lines in the geometry content area of middle school mathematics 1 by the 2015 revised Korean mathematics curriculum may potentially generate mathematical intuitions that do not correspond to the perspective of Euclid geometry, this study suggest that attention is needed in the learning process about points and lines.

The purpose of this study was to analyze the commemoration culture of Vietnam War Memorials (VWM) in Vietnam. Through site survey, the researcher selected 23 VWM in Vietnam and analyzed 5 categories: memorial type, design concept and narratives, location and spatial form, landscape elements, and content expressed in landscape details. The results are as follows: 1. Because of the long, drawn out Vietnam War, which lasted from 1955 to 1975, VWM were divided into 10 types mainly as soldier cemeteries based on a traditional memorial style, battlefields and places of tragedies considering sense of place, war museums representing victory and atrocity in war, and peace parks promoting reconciliation and peacemaking. 2. The analysis revealed that the main concepts and narratives of VWM were to value the victims of the Vietnam War, remember soldiers' contributions, highlight the victory in war and resistance to the United States, and express a sense of place. Peacemaking applied only to My Lai Peace Park and Han-Viet Hoa Binh Cong Vien, built by international cooperation. 3. Cemeteries and appreciation memorials were designed to follow a traditional memorial space form that highly regard both axis and symmetry. The design concept at battlefields and places where tragedies occurred depended mainly upon a sense of place and used symbolic landscape elements to compensate for the undefined concept. 4. Sculptures and towers were mainly used to highlight war victory and resistance as the representative style of a Socialist country, weapons and pictures exhibited in war museums and battlefield showed the reality and strain of war. Symbolic elements of Buddhism and Confucianism were often introduced as a way to venerate the memory of deceased persons. 5. The state and heroic actions in the Vietnam War were realistically depicted on sculptures and walls. Also, the symbolic phrase, 'TO-QUOC-GUI-CONG' meaning 'our country remember your achievement', were written on the memorial tower and 'Quagmiire' was used to metaphorically represent the difficulties faced by the U.S. military on battlefields during the war and the uncertainly that pervaded U.S. society in those days. 6. In VWM, ideologies like nationalism, patriotism, socialism, capitalism were mixed and traditional cultures like Buddhism, Confucianism, Taoism were inherent. Differing from their Confucianism culture, war heroes, particularly including women, were often described by sculpture, monument, and pictures and the conflict in and outside the country regarding the Vietnam War was shown. Further study will be required to analyze design characteristics of VWM in the u.s. and to understand the difference in commemoration cultures between Vietnam and the U.S.
