본 연구의 목적은 임신 중절을 경험한 기혼 여성이 가족세우기를 통해 겪는 변화를 알아보는 데 있다. 결과적으로 그 변화는 임신 중절 경험에 대한 새로운 인식과 기혼 여성 본인과 가족 관계에서의 변화가 될 것이다. 본 연구 참여자들은 임신중절을 경험한 40~60 대 기혼 여성 9명이었으며, 자료 수집은 개별적인 심층면담을 통하여 가족세우기 경험 전, 직후, 한 달 후로 3회기 이루어졌다. 본 연구는 Colazzi의 현상학적 방법론을 바탕으로 이루어졌으며, 분석 결과 15개의 주제 모음과 3개의 범주가 도출되었다. 이 연구를 통해 임신중절을 경험한 기혼여성들은 해당 경험을 의식적으로 떠올리지 않았음에도 그 경험이 삶 전반에 걸쳐 부정적인 영향을 미치고 있다는 것을 결과로 도출할 수 있었다. 기혼 여성이 경험하는 가족세우기는 무의식에 감춰진 긴장관계가 대리인을 통해 가시화되면서, 얽힘을 풀 기회를 제공한다. 그리고 그러한 기회를 통해 기혼 여성은 궁극적으로 임신중절 경험에 대한 새로운 인식과 가족관계의 변화를 겪게 되며, 자신과 가족관계에서 회복력을 키울 뿐 아니라 정서적 안정감을 가지게 되는 경험을 하게 된다.

We present a family of constant-amplitude constellations of even dimensions 8 and above. These constellations allow trellis coded modulation to be implemented without the usual penalty paid for constellation expansion. The new constellations are generated by concatenating either n QPSK points or n QPSK points rotated by 45 degrees, for any n $\geq$ 4. Our constellations double the number of points available for transmission without decreasing the distance between points and without increasing the average or peak energies, introducing asymmetry, or increasing the modulation level. Effective gains of 2.65 dB with minimum complexity through 6.42 dB with moderate complexity are demonstrated using the 8D constellation.

CMA나 MCMA 적응 블라인드 등화 알고리즘은 특별한 형태의 신호점을 원하는 신호점로 간주하므로써 완전한 등화에 도달시에도 원래의 신호점과의 불일치로 인한 오차가 불가피하다. 본 논문에서는 축소 신호점 대신에 결정된 원래의 신호점을 이용한 새로운 오차함수를 도입하여 빠른 수렴 속도로 정상상태에 도달하며, 정상상태에서의 오차를 크게 개선한 새로운 적응 블라인드 등화 알고리즘을 제안한다. 컴퓨터 모의실험을 통하여 제안한 알고리즘이 반송파 위상 복원을 가지는 CMA 및 MCMA등과 같은 CMA 계열의 적응 블라인드 등화 알고리즘들에 비해 잔류 심볼간 간섭과 수렴 속도면에서 향상된 성능을 가짐을 확인 하였다.

The CMA and MMA blind equalization algorithm has the inevitable large residual error caused by mismatching between the symbol constellation at a steady state after convergence. Stop-and-Go algorithm has a very superior residual error characteristics at a steady state but a relatively slow convergence characteristics. In this paper, we propose a SAG-Flagged MMA as a new adaptive blind equalization algorithm with a Stop-and-Go flag which follows a flagged MMA in update scheme of tap weights as appling the flag obtaining from Stop-and-Go algorithm to MMA. Using computer simulation, it is confirmed that the proposed algorithm has an enhancing performance from the viewpoint of residual ISI, residual error and convergence speed in comparison with MMA and Stop-and-Go algorithm. Algorithm has a new error function using the decided original constellation instead of the reduced constellation. By computer simulation, it is confirmed that the proposed algorithm has the performance superiority in terms of residual ISI and convergence speed compared with the adaptive blind equalization algorithm of CMA family, Constant Modulus Algorithm with Carrier Phase Recovery and Modified CMA(MCMA).

This research was based on a case study of a child who experienced difficulties in ego development due to her mother's compulsive and depressed behavior. Twenty-four therapeutic play sessions, including 16 sessions involving sandplay, were conducted. Based on discussions by Neumann and Kalff, the child's early psychic development and ego development were observed during these sandplay. As part af this investigation, I conducted counseling sessions in the sandbox where the atmosphere was free and safe. The sessions were based on mother-child unity with the therapist. As a result, the child exhibited restoration of mother-child unity and showed the journey of constellation of self and ego development. The results of this research indicate the effectiveness of sandplay in accelerating ego development.

Various ceremonial flags were of great importance to the rulers who wished to have the absolute authorities for governing the people. Perhaps nothing indicated the ideas, thoughts and symbols of a certain period and people than the ceremonial flags. The ceremonial flags used in the old China and Korea took the shapes of the heaven and the earth, representing the social backgrounds and thoughts. This study was limited only to the discussion of the heaven-shaped patterns of the ceremonial flags. The 28 constellations of the heaven, in the Oriental way of thinking, were considered to express the immortal powers of Providence and the political domination of the earth. Hence the Polaris, the center of the heaven, symbolized the whole family of king, prince, child born of a concubine and royal harem. Among the constellation pictures were those of Han period, wall painting of old tombs in Koguryeo kingdom and old Japanese kingdom. Referring to the Emperor's ceremonial flags in Daemyeongjibyei, symbolic meanings changed historically and the complete systems of the ceremonial flags were established in Song period when the divine person was drawn on the flags. Animals concerned properly with the particular star and the shapes of the star were both drawn on the flags in Won period and only the shapes of the particular star in Myeong period. In the Imperial enthronement of Kojong the ceremonial flags might be made by the examples of those of Myeong period and remains are now found at Changdeok Palace, which need a further study because the references in detail are not available.

Based on an interleaving technique and quadriphase periodic complementary sequence (CS) mates, this paper presents a method for constructing a family of 16-quadrature amplitude modulation (QAM) periodic CS mates. The resulting mates arise from the conversion of quadriphase periodic CS mates, and the period of the former is twice as long as that of the latter. In addition, based on the existing binary periodic CS mates, a table on the existence of the proposed 16-QAM periodic CS mates is given. Furthermore, the proposed method can also transform a mutually orthogonal (MO) quadriphase CS set into an MO 16-QAM CS set. Finally, three examples are given to demonstrate the validity of the proposed method.

The button is a part of costume. But it has the symbolism of costume in itself and reflects the sociocultural phenomena. The purpose of this study is to clarify symbolism of button of eighteenth and nineteenth century which had been most popular. This study is based on the library research. Through this paper, I reached conclusions as follows. The symbolism of button is found in various ways. First, Aesthetics is found in material, color, design and type etc. of button. Especially Indian silver button of abstract type shows well distinctive aesthetics of Indians. Second, The material and the number of button vary with one's status and show off one's privilege. I England, there was the rule, in which the symbol of the King was a silver button with a figure of lion. The livery button represents his family to the nble and shows the meaning of obedience to the servant. Third, The button on uniform varies with ranks. This is prominent in a uniform of a soldier or a policeman. Fourth Material and craft of button show one's economic position. The button gives a Very good picture of what one's life was then. Precious button with gold, silver, and other jewels is an index to one's property. Fifth, The button of political event is used for election, which shows the face and the name of runner. Besides that, there were buttons designed for the flag or the slogan for political event. Sixth, The button of social event reflects a social phase of life in war or revolution, for example, it satirizes the burning of the Bastille in the French Revolution, or the taxpayer bearing the burden. Seventh, the buttons that symbolize a historic event are made to commemorante an epochal and critical occurrence or an important person's birth, death, visit to some place, etc., Eighth, there were well-known persons, for example, a president, a king, a queen, a singer, or an artist in the buton of personality. Nineth, The button of one's company shows one's community in figures or pictures, that is, this button is used as a symbol one's community. Tenth, The button varies with the development of science and technology. It gives a very good picture of what it was and what the technological level was. Eleventh, The buttons that symmbolize on occupation most impressively are uniform buttons. Symbolic marks related with a particular occupation are carved on the buttons of compary employees' uniforms. Twelfth, Various natural phenomena are designed to appear on buttons, Some express themselves simply as they are, and others appear as a symbolic form such as environmental relationship between men and nature, four seasons, a constellation and all other natural things occurring during a year. Finally, The button of rebus is a motto expressed by a combination with objects figures, letters, words, or phrases.
