The major concept of Sasang typology is that the disease susceptibility and drug response as well as physiological characteristics are presumed to be different depending on their Sasang types. Although characterizing fundamental basis of their traits are crucial in this research field, only pathological susceptibility and physical appearances were thoroughly studied. We evaluated their physiological characteristics by tapping psychological, physical and genetic traits of each Sasang types. After determining the Sasang type of one hundred three college students based on the Questionnaire for the Sasang Constitution Classification, the psychological, physical and genetic traits of each type were analyzed with the Myers-Briggs Type Indicator (MBTI), Bioelectrical Impedance Analysis and genetic polymorphism test, respectively. Each of the Sasang types showed significantly different profiles (Generalized estimation equation, coef=11.88, z=2.13, p=0.033), and could be distinctively classified based on their MBTI scores (discriminant analysis Wilks Lambda=0.611, df=8, chi-square=36.7, p<0.001). Subjects with the So-Eum type (Introversion and Judging) and the So-Yang type (Extroversion and Perceiving) showed contrasting psychological features, however they had similar anthropometric characteristics. Subjects with the Tae-Eum type showed bigger Body Mass Index ($R^2$=0.22, df=4, 74, F=5.07, p=0.001) and body shape compared to others. Although there were no significant differences in G-protein beta-3 subunit polymorphism, angiotensin-converting enzyme polymorphism and Methylenetetrahydrofolate reductase polymprhisms among groups with Sasang types, it was shown that the dopamine system could be one for genetic marker for Sasang typology. These results demonstrated distinctive and essential traits of Sasang typology using reproducible psychometric, anthropometric and genetic evaluations. We also found that the Sasang typology was a bio-psychological typology which could show trait-specific guideline for individualized medicine.

Introduction The purpose of this study was to review thirty years of studies on psychological characteristics of Sasang types to delineate generalizable psychological theories pertaining Sasang typology. Methods Research articles providing psychometric characteristics of each Sasang types were extracted from five database written in Korean and English. Demographic features of the participants, clinical methods for the Sasang type classification, and psychological characteristics of each Sasang types were reviewed and summarized. Results A total of 59 peer-reviewed research articles were found to be published from 1991 to 2018, and the So-Yang and So-Eum Sasang type showed distinctive and contrasting psychological features. The overlap between Eastern and Western psychology in Behavioral Activation and Inhibition System was highlighted as for personality studies, but the anxiety as a pathological factor was not found distinguishable between Sasang types. Discussion The present systematic review provided insight on psychological perspectives of Sasang typology, and would be useful for establishing unique construct of Korean Psychology.

Objectives: Although medical typologies based on indigenous biopsychological ideas have been described, their integrity has been questioned due to its theory-driven nature in categorization. Therefore, studies on the Sasang typology, a temperament-based traditional Korean medicine, are needed to examine whether it is possible to classify types of specific biopsychological profiles using data-driven analysis. Methods: Psychological measures of the Eastern Sasang Personality Questionnaire (SPQ) and Western NEO-Personality Inventory (NEO-PI) along with physical measures and Sasang types were acquired from 2,049 participants. Latent groups based on the SPQ and NEO-PI subscale scores were extracted using Latent Profile Analysis. Their psychosomatic features were then compared with those of Sasang types. Results: Three SPQ-based latent groups showed distinctive psychological and physical features consistent with those of Sasang types. However, four NEOPI-based latent groups presented only psychological features. Furthermore, SPQ-High and SPQ-Low latent groups demonstrated similar psychosomatic profiles to those of So-Yang and So-Eum Sasang types, respectively. Conclusions: This study illustrates that biopsychological profiles of Sasang types are supported by psychosomatic features of latent groups based on SPQ of Eastern psychology, signifying that the categorization of Sasang typology have acceptable validity and reliability.

This study classified the current work-life balance of full-time female paid workers and tested the typology by using the 2009 Korean Time Survey. The categorization demographic and psychological characteristics of women belonging to each type were comparatively analyzed. It was found that full-time female paid workers used an average of 435.7 minutes for work, 146.4 minutes for family, 104.5 minutes for leisure, and 17.7 minutes for growth. On the basis of times used in each area of work and life, individuals were classified into family-oriented type, work-leisure parallel type, work-oriented type, work-growth parallel type, and work-family parallel type. Psychological characteristics were examined by type. The work-oriented type women experienced feelings of lack of time and fatigue the most compared with women of other types. From examining the influence that the amount of time used in each area of work and life had on psychological characteristics, it was shown that the activity time relevant to leisure influenced psychological characteristics the most. Lastly, based on the limitations of this study, future assignments are discussed.

Objectives : The objective of this study was to examine the biopsychological traits of each Sasang type from a personality theory perspective. Methods : A review of different theories of personality is provided, in addition to review of ten previous studies on the psychological characteristics of the Sasang types. Results : 1. Similarities and differences were found between Sasang typology and Western theories of personality. 2. The prevalence of Sasang type was 28:36:36 (So-Yang:Tae-Eum:So-Eum), and the majority of the study sample were males in their twenties. 3. The Yin-Yang and Large-Small axes of Sasang typology were comparable to Eysenck's Extraversion and Neuroticism dimension. So-Yang type showed high extraversion and low neuroticism, and So-Eum type exhibited low extraversion and high neuroticism. Tae-Eum type was extravert and neurotic, and highly distinctive in such physical traits as Body Mass Index and blood triglyceride concentration. 4. We make recommendations for future studies on Sasang typology within a biopsychosocial and cognitive framework. Conclusions : This study demonstrates the possibility of Sasang typology being explicable from a cross-cultural biopsychosocial theory.

Psychological typology in analytic psychology is used not only for ascertaining the attitude or function of the conscious ego, but also as one blueprint for the individuation process. We all know the need to emphasize an awareness of the deployment and development of the superior function, the secondary function, the third function and the inferior function for the individuation process. This study has the goal of refining our awareness of this deployment and development of typological functions. The questionnaires of the Myers-Briggs Type Inventory and the Gray Wheelwrights Jungian Type Survey use the method of a forced-choice questionnaire, on the assumption of a bi-polarity hypothesis. But the questionnaire of the Singer-Loomis Type Deployment Inventory uses the Likert scale. It is able to show the deployment of the superior function, the secondary function, the third function and the inferior function visibly. It allows us to test the subject at stated periods for his/her development or change of psychological typology. The Singer-Loomis Type Deployment Inventory is a statistically superior method for showing Jung's psychological typology relative to both the Myers-Briggs Type Inventory and the Gray Wheelwrights Jungian Type Survey. I have studied how the original authors of The Singer-Loomis Type Deployment Inventory understood Jung's psychological typology. I produced the reliability and the item-discrimination power of the Korean Version of the Singer-Loomis Type Deployment Inventory. On the basis of this study, I produced the revised Korean version 1 of Singer-Loomis Type Deployment Inventory.

This study aimed to predict psychopathology based on personality measures via supervised machine learning methodology. We implemented the Singer-Loomis Type Deployment Inventory (SLTDI) for psychological typology and the Korean version of the Revised Symptom Checklist 90 (KSCL-95) for psychopathology. A total of 521 Korean adults from across the country participated in the online survey. Statistical analyses including correlation, k-means cluster analysis, classification, and regression-based decoding were performed. Results revealed four differentiated clusters on the spectrum of clinical severity. Moreover, SLTDI could distinguish between hypothesis-driven and data-driven clusters by chance. KSCL-95's three subcategories, as well as its validity, were accurately classified. Regression-based decoding results showed that their typology data significantly predicted social desirability, depression, anxiety, obsessive-compulsive disorder, PTSD, schizophrenia, stress vulnerability, and interpersonal sensitivity significantly. Overall, these findings suggest that personality tests could be utilized to screen for the severity of psychopathology and to implement prevention and early intervention strategies.

Objectives Many studies have suggested different neurobiological findings and clinical courses in alcoholism. Recently, subtyping in alcohol dependence has become essential to overcome the heterogeneity of patients. Among several criteria of subtypes, Lesch's typology is proposed to integrate biological, social, and psychological factors. This review provides neurobiological findings and treatment-responses of alcohol dependence according to Lesch's typology. Method We searched the international published medical literature using the search terms 'Lesch's typology' and 'alcohol dependence' and using the limits 'human'. Results We identified 17 studies with subjects of alcohol dependence according to Lesch's typology. Conclusion They indicated that each subtype of Lesch's typology can have specific neurobiological factors and different clinical responses as follows. Lesch's subtype 1 is characterized by severe withdrawal symptoms and associated with elevated glutamate and homocysteine. Lesch's subtype 2 is defined by individuals who drink alcohol as self-medication for anxiety. Their craving has significant positive correlations with prolactin, leptin level, or intake-volume (vasopressin). Lesch's subtype 4 is related to cerebral dysfunction and associated with increased glutamate and left-handedness. Clinical trials showed that naltrexone was effective in Lesch's subtype 3 and 4 patients, while acamprosate was effective in the subtypes 1 and 2.

Objectives: In this study, we examine whether Sasang constitutions include all 8 attitude-function types, forming a complete paradigm from the perspective of Jungian psychological type theory. Methods: Analysis of the meanings of psychological attitudes and function of each Sasang constitution was performed, comparing them with the typological theories of C.G.Jung and John Beebe, both of whom are eminent minds in Jungian typology. Results and Conclusions: (1) Each Sasang constitution had all 8 psychological attitude-function combinations, which are diversely differentiated by type within their conscious and unconscious psyches. This is likely because attitudes and functions that develop in the conscious mind build up compensating attitudes and functions in the unconscious. (2) It seems that extroversion and introversion coexist within every Sasang constitution as psychological descriptions reported by Lee, Je ma state. The superior and inferior functions are disposed in the order of organ size in Sasang constitutions, but dominance of extroversion or introversion as defined by Jung's concepts of attitude does not seem to be determined by constitution.

Most of the software development is determined by the hard skills of project participants and capacity management and operations. However, failure of the current software development is very high. Since the development of the exploration of human psychology continues, the study that there is an association between the preferences of personality and work preference has been actively conducted. It is found out that there is a relationship of preferences in MBTI, the test tool of psychological typology, and those for the work of the ICT engineers tuned to the software development cycle. By using the information on the soft skills associated with software development for the psychological typology, it can be understood the preference of the software development process. In this paper, we develop a program for software development process to allow personality type to be classified with using the soft skills to find ways to improve education and collaboration capabilities of ICT engineers.
