The purpose of this study was to examine self esteem and reactions on LMT projective technique to a group of scientifically gifted high school students and general high school students. For that purpose, 113 participants from scientifically gifted high school and general high school were asked to fill out self esteem questionnaire and draw a LMT. The results were analyzed by using SPSS.PASW18. The results are as follows: First, overall self esteem of gifted students were higher than general students. Second, reactions on LMT of gifted students and general students were examined. As a result, there were statistically significant differences in four items; integration of landscape composition, expression of distance and space, number of additional items, existence of doors and windows. The result of this study showed significant differences between the two groups in self esteem and LMT scores.

This study was performed to investigate the North Korean defectors's depression through the CES-D and a projective test simultaneously. So 40 North Korean defectors and 40 South Koreans participated in this study. The results are the following. First, the North Korean defectors demonstrated more higher CES-D scores than the South Koreans, while there were not significant differences in the Rorschach depression-related indexes, DEPI, CDI, S-CON between two groups. Second, at the analysis of the sex difference effect, women among the North Korean defectors showed the most high CDI index scores. In addition, we analyzed the mean differences between two groups for morbid content, shading response, achromatic response, human movement response, form dimension response, Lamda, and the number of total response. However, there are not significant differences between two groups for those variables, except for form dimension(FD) response. It suggested the probability that the North Korean women defectors could experience more psychological distress underlyingly than the North Korean men defectors. Third, most importantly, the correlation between CES-D and DEPI in the Rorschach test was significantly different in the two groups(the North Korean defectors and the South Koreans). In conclusion, the self-report of the North Korean defectors on depression could be exaggerated. So we should be cautious to interpret the self report results of the North Korean defectors.

With the increase of the elderly population, demand for improvement of quality of life and measurement of mental state has increased. However, much of the self-reported diagnosis does not reflect cognitive impairment. This study aims to measure the dwelling depression by applying K-HTP and verify the validity. 301 persons over 65 years old who live as single and couple households in Daejeon and surrounding districts were surveyed during 22 January to 2 February, 2018. The correlations between the dwelling depression and K-HTP are clarified and the validity was evaluated. The correlations between the geriatric dwelling depression index(GDDI) and the GDDI based on K-HTP(GDDI-K) are clarified and the accuracy was analyzed. The results showed that the K-HTP can be utilized to measure the dwelling depression. We suggested a new measurement tool and provide further benefits for researches on diagnoses using the projective method.

Mirror symmetry for del Pezzo surfaces was studied in [3] where they suggested that the mirror should take the form of a Landau-Ginzburg model with a particular type of elliptic fibration. This argument came from symplectic considerations of the derived categories involved. This problem was then considered again but from an algebro-geometric perspective by Gross, Hacking and Keel in [8]. Their construction allows one to construct a formal mirror family to a pair (S, D) where S is a smooth rational projective surface and D a certain type of Weil divisor supporting an ample or anti-ample class. In the case where the self intersection matrix for D is not negative semi-definite it was shown in [8] that this family may be lifted to an algebraic family over an affine base. In this paper we perform this construction for all smooth del Pezzo surfaces of degree at least two and obtain explicit equations for the mirror families and present the mirror to dP₂ as a double cover of ℙ².

A 3D reconstruction technique from stereo images that requires minimal intervention from the user has been developed. The reconstruction problem consists of three steps of estimating specific geometry groups. The first step is estimating the epipolar geometry that exists between the stereo image pairs which includes feature matching in both images. The second is estimating the affine geometry, a process to find a special plane in the projective space by means of vanishing points. The third step, which includes camera self-calibration, is obtaining a metric geometry from which a 3D model of the scene could be obtained. The major advantage of this method is that the stereo images do not need to be calibrated for reconstruction. The results of camera calibration and reconstruction have shown the possibility of obtaining a 3D model directly from features in the images.

This note contains the following results for a ring A : (1) A is simple Artinian if and only if A is a prime right YJ-injective, right and left V-ring with a maximal right annihilator ; (2) if A is a left quasi-duo ring with Jacobson radical J such that $_{A}$A/J is p-injective, then the ring A/J is strongly regular ; (3) A is von Neumann regular with non-zero socle if and only if A is a left p.p.ring containing a finitely generated p-injective maximal left ideal satisfying the following condition : if e is an idempotent in A, then eA is a minimal right ideal if and only if Ae is a minimal left ideal ; (4) If A is left non-singular, left YJ-injective such that each maximal left ideal of A is either injective or a two-sided ideal of A, then A is either left self-injective regular or strongly regular : (5) A is left continuous regular if and only if A is right p-injective such that for every cyclic left A-module M, $_{A}$M/Z(M) is projective. ((5) remains valid if 《continuous》 is replaced by 《self-injective》 and 《cyclic》 is replaced by 《finitely generated》. Finally, we have the following two equivalent properties for A to be von Neumann regula. : (a) A is left non-singular such that every finitely generated left ideal is the left annihilator of an element of A and every principal right ideal of A is the right annihilator of an element of A ; (b) Change 《left non-singular》 into 《right non-singular》in (a).(a).

In this paper, we propose a self-calibration of a multi-camera system using factorization techniques for realistic contents generation. The traditional self-calibration algorithms for multi-camera systems have been focused on stereo(-rig) camera systems or multiple camera systems with a fixed configuration. Thus, it is required to exploit them in 3D reconstruction with a mobile multi-camera system and another general applications. For those reasons, we suggest the robust algorithm for general structured multi-camera systems including the algorithm for a plane-structured multi-camera system. In our paper, we explain the theoretical background and practical usages based on a projective factorization and the proposed affine factorization. We show experimental results with simulated data and real images as well. The proposed algorithm can be used for a 3D reconstruction and a mobile Augmented Reality.

Until recently there were arguments on the existence and the definition of childhood depression. In DSM-III(1980) childhood depression was accepted as the formal psychiatric disorder in childhood. As the diagnostic criteria for childhood depression is less clearly defined than those for other psychiatric disorders as well as prominent age-related variations in depression symptomatology, informations from various sources are very important in accurate diagnosis of childhood depression. Present study reviewed various assessment methods such as self-report questionnaires, interviews, behavior rating scales, structured tests and projective techniques with discussion on the merits and limitations of each method. Also several issues on the reliability and the validity of assessment techniques for childhood depression were discussed.

Author reviewed psychodynamics and psychoanalytic treatment of obesity. A variety of psychodynamics and unconscious conflicts have been described in obese patients : eating as a defense against depression, eating as a substitute for maternal love, obese body as a larger penis, and eating as a self-soothing. There was a gross neglect of certain normal parenting roles in obese family. The parenatal superego structure was not as perfectionistic. As with children and other patients with preoedipal pathology, in obese patients the analyst in addition to being transference object is a new and different object who promote healthy maturation. Because of obese parients, in there projective identification, can provoke intense countertransference, the analyst have to consider it. On the other hand, many analysts' countertransferences to superobese patients is that huge person recalls one's own childhood relationship with adults and bring forth a feeling of helplessness.

Background: Many people experience varying levels of discomfort when confronted with the prospect of dental treatment. Dental treatment can be a traumatic experience, especially for children and adolescents with dental anxiety. In this age group, dental fear causes a significant problem in dental management and has been related to severe dental caries and dental pain. The Dental Fear Survey (DFS) is the most widely used measure of dental fear. This study was undertaken to develop the Korean version of the DFS (K-DFS) and test its reliability and validity. Methods: The K-DFS, which uses projective techniques to measure children's and adolescents' dental fear, was developed. The DFS was translated into Korean and participants were selected via convenience sampling. Reliability and validity were tested using data from a sample of 813 middle school students in Gyeonggi Province, selected from the Self questionnaire survey. The K-DFS was administered twice to 102 adolescents aged 12-15 years. Results: The K-DFS had high internal consistency reliability (99.1%) but low test-retest reliability. Conclusions: The results indicate that the Korean versions of the DFS have good internal consistency reliabilities and test-retest validities. However, we need to further examine the test-retest reliability of the K-DFS and replicate the current study in different samples covering various age groups.
