  • The conception of 'earth(土)' belonging to the five evolutive phases(五行) is cognized that it is not partial to any side differing from other four phases and it can control other four phases so, it is the first gate to enter the process of changes. In the five organs(五臟), the spleen come under the earth phases and it have been very importantly considered for past to now in oriental medical history, for example by Li Dongyuan(李東垣). In this study, the results are summarized as the followings. 1. The term of the acquired constitution(後天) made by So-ong(邵雍), a scholar in the north so-dynasty, is used in the study of the book of changes(易經). And he said "The inborn constitution(先天) is the law of the nature itself and, the acquired constitution(後天) is the law of making the changes with the nature." In the myung-dynasty Li jungjae(李仲梓) made extract from this remarks 10 define that the spleen is the basis of the acquired constitution. So it considered that the the idea of changes(易) had an effect on the oriental medicine. 2. The one element of five phases, earth is the center of the changes and it composes the power of life with the sangsu(生數)-1, 2, 3, 4, and the sungsu(成數)-6, 7, 8, 9. In this process, the earth is the basis of the changes of the five phases. At the same time the spleen carry out the important physiological role in the humanbody controlling the other four organs. 3. In the change of the universe, the repetitionary movement of Yin(陰) and yang(陽) is the action of earth and it means illimitable division. In the course of this division all things change to new phases for example, the food changes 10 the ki(氣) through the action of spleen and stomach. So the organ of spleen and stomach is the space that the action of change occur. 4. Consequently the conception of bi(脾) is close to the pancreas that the spleen. And the duodenum is close to the conception of stomach because the space is the site of mito(未土). 5. The action of yin and yang in the ancient taegukdo(太極圖) is close 10 the connection of N-pole and S-pole. In the humanbody the two power is compared to the action of spleen and kidney, that means expansion and contraction. Also it means the inborn constitution and the acquired constitution so, it applyed to the all things in the universe.

  • Anthocyanin, a phenolic compound, is a pigment that shows blue or red color in the fruit, petal and other tissues. It is an important factor in grape berry skin pigment and accumulates only in the skin. This skin-specific accumulation of anthocyanin has been reported to be regulated by the ufgt gene which encodes UDP-glucose: flavonoid 3-O-glucosyltransferase that participates in the biosynthesis of anthocyanin. The ufgt gene is expressed only in berry skin, while the other genes involved in the biosynthetic pathway are expressed in both skin and flesh tissues. In order to determine whether anthocyanin accumulation is primarily regulated by compartment of UFGT, a ufgt cDNA clone was isolated from grape berry, its open reading frame was ligated in pBI121 vector in either a sense or an antisense orientation under the control of the CaMV35S promoter and the recombinant constructs were incorporated into tobacco plants. Several transgenic lines were selected and characterized to determine the level of expression of the grapevine ufgt transcript and endogenous homologs of tobacco. Compared to the wild-type, the amount of anthocyanins in sense transgenic plants increased by 44%, while the amount of anthocyanins in antisense transgenic plants decreased by 88%. In addition, the color of flowers became intense in the sense transgenic plants. These results suggest that over-expression or repression of the ufgt gene affected the accumulation of anthocyanin in flowers of tobacco.

  • Purpose - This study aims to (a) analyze local citizens' perception of a local company, the Gwangyang Steel and Iron Company (GSIC); (b) compare the perception toward the local company with that of national citizens' perceptions towards many other unspecified companies, which were surveyed biannually by The Korea Chamber of Commerce and Industry (KCCI); and (c) analyze how such companies evaluate perceptions towards them, in relation to citizens' socioeconomic position, such as their education status. Research design, data, methodology - The data were collected using a questionnaire, which was given to a sample of local citizens in cities. To test the hypotheses, factor analyses, a t-test, and an ANOVA were conducted. The total number of respondents was 1798. The data gathered from the respondents of the sample were analyzed using SPSS Win 19.0 software. Perception towards the company was evaluated on the corporate favorite index (CFI). The CFI index shows how positive citizens feel towards a company. It is calculated using five leading factors, consisting of the following: contribution to the economy, productivity, international competitiveness, social contribution, and ethical management. The higher the level of positive feelings exhibited, the closer the index will come to 100. Results - As a result of the analysis, the CFI index towards the GSIC stood at 67.3. The CFI index towards the company is 16.5 points higher than that of the index towards the many other unspecified companies, which were surveyed by the bi-annual KCCI study in the first half of 2011. The other five indexes stood as follows: contribution to the economy, productivity, social contribution, and ethical management was 69.2, 71.2, 64.6, and 58.6, respectively. These indexes are 18.3, 4.6, 27.6, and 35.6, respectively, higher than those found by the KCCI study. However, international competitiveness is 73.0 (9.8 points lower than that of the KCCI study). This survey thus shows that the CFI of the local citizens towards the global company GSIC is very high when compared with the CFI index towards the many other unspecified companies that was determined by the KCCI survey. Conclusions - This survey shows that local citizens have high expectations of economic activity, increasing working opportunities, and regional cooperation projects from the local company, GSIC. In addition, the CFI index towards GSIC evaluates results depending on the respondent's relationship with the company, and their educational status. Respondents, whose family or relatives were working as employees of GSIC, have relatively positive perceptions of GSIC, and respondents with a relatively higher educational status also share positive perceptions. Local citizens expect the profit-making of the company to operate in accordance with management activities, and at the same time, they expect that the wealth generated by the company will return to wider society.

  • The aim of this study was to examine the phosphate (P) removal by quintinite from aqueous solutions. Batch experiments were performed to examine the effects of reaction time, temperature, initial phosphate concentration, initial solution pH and stream water on the phosphate adsorption to quintinite. Kinetic, thermodynamic and equilibrium isotherm models were used to analyze the experimental data. Results showed that the maximum P adsorption capacity was 4.77 mgP/g under given conditions (initial P concentration = 2-20 mgP/L; adsorbent dose = 1.2 g/L; reaction time = 4 hr). Kinetic model analysis showed that the pseudo second-order model was the most suitable for describing the kinetic data. Thermodynamic analysis indicated that phosphate sorption to quintinite increased with increasing temperature from 15 to $45^{\circ}C$, indicating the spontaneous and endothermic nature of sorption process (${\Delta}H^0=487.08\;kJ/mol$; ${\Delta}S^0=1,696.12\;J/(K{\cdot}mol)$; ${\Delta}G^0=-1.67$ to -52.56 kJ/mol). Equilibrium isotherm analysis demonstrated that both Freundlich and Redlich-Peterson models were suitable for describing the equilibrium data. In the pH experiments, the phosphate adsorption to quintinite was not varied at pH 3.0-7.1 (1.50-1.55 mgP/g) but decreased considerably at a highly alkaline solution (0.70 mgP/g at pH 11.0). Results also indicated that under given conditions (initial P concentration=2 mgP/L; adsorbent dose=0.8 g/L; reaction time=4 hr), phosphate removal in the stream water (1.88 mgP/g) was lower than that in the synthetic solution (2.07 mgP/g), possibly due to the presence of anions such as (bi)carbonate and sulfate in the stream water.

  • As considering a comparison study of the structure of mind and psychologic type of C.G Jung to Ji-In-Lon and Sa-Sang constituition of Lee Je Ma, I've got the following conclusion. 1. The study of the structure of mind of Jung and Ji-In-Lon of Lee Je ma have a important meaning to each theory of type of men. They developed their own peculiar theory of type men by the analysis of the mind of men. 2. Jung explained the organization of recognition by four phase theorical structure; consciousness, personal unconsciousness, collective unconsciousness, self. Lee Je Ma explained the organization of recognition by four phase theorical structure;Sa, Sim, Sin, Mul. And theory of type of men, Jung established four type; Tae-Yang-In, Tae-Um-In, So-Yang-In, So-Um-In, They all established the four phase structure, which have things in common. 3. Jung studied the consciousness and unconsciousness and Lee Je Ma studied the Sung-In, Eui, Ye, Ji, and Sim-Yock-Bi, Bak, Tam, Na. I think they have a close relationship. And I think there is relationship between consciousness, unconsciousness to Gun-Ja-Ji-Sim, So-In-Ji-Sim. 4. I think there is thought of relationship between Lee Je Ma's Dae-Dong, Gak-lip, Hang-gi-ji, Hang-gi-hang and Ho-sun, Oh-ak, Sa-sim, Tae-hang and relationship of internal organ's size to Jung's the first function, second function, third function, fourth function. 5. I think the relationship between the type of Jung;thinking type, feeling, type, sensation type, intuition type to the type of Lee Je Ma; Tae-Yang-In, Tae-Um-In, So-Yang-In, So-Yang-In, So-Um-In needs more study.

  • Objective: The purpose of this study was to precede the acceptance study based on automation steps and user experience that was lacked in the past study on the core technology of autonomous vehicle, ADAS. The first objective was to construct the acceptance model of ADAS technology that is the core technology, and draw factors that affect behavioral intention through user experience-based evaluation by applying driving simulator. The second one was to see the change of factors on automation step of autonomous vehicle through the UX/UA score. Background: The number of vehicles with the introduction of ADAS is increasing, and it caused change of interaction between vehicle and driver as automation is being developed on the particular drive factor. For this reason, it is becoming important to study the technology acceptance on how driver can actively accept giving up some parts of automated drive operation and handing over the authority to vehicle. Method: We organized the study model and items through literature investigation and the scenario according to the 4 stages of automation of autonomous vehicle, and preceded acceptance assessment using driving simulator. Total 68 men and woman were participated in this experiment. Results: We drew results of Performance Expectancy (PE), Social Influence (SI), Perceived Safety (PS), Anxiety (AX), Trust (T) and Affective Satisfaction (AS) as the factors that affect Behavioral Intention (BI). Also the drawn factors shows that UX/UA score has a significant difference statistically according to the automation steps of autonomous vehicle, and UX/UA tends to move up until the stage 2 of automation, and at stage 3 it goes down to the lowest level, and it increases a little or stays steady at stage 4. Conclusion and Application: First, we presented the acceptance model of ADAS that is the core technology of autonomous vehicle, and it could be the basis of the future acceptance study of the ADAS technology as it verifies through user experience-based assessment using driving simulator. Second, it could be helpful to the appropriate ADAS development in the future as drawing the change of factors and predicting the acceptance level according to the automation stages of autonomous vehicle through UX/UA score, and it could also grasp and avoid the problem that affect the acceptance level. It is possible to use these study results as tools to test validity of function before ADAS offering company launches the products. Also it will help to prevent the problems that could be caused when applying the autonomous vehicle technology, and to establish technology that is easily acceptable for drivers, so it will improve safety and convenience of drivers.

  • In this paper, the method of designing a wideband antenna has been introduced through the design technique that simultaneously employs L- and slot-type feeds. Using the two kinds of feeds and additional fence structure, a compact wideband patch antenna has been realized. The size of the patch has been reduced by about 30 % based on the low frequency(824 MHz) and the full fractional bandwidth is wider than 100 %. The L-feed element is for the EM coupling feeding at the low frequency, while it functions as a feeding line for the power coupling through the slot at the high frequency. The proposed antenna has been designed not only for wideband operations but also for a proper array element with a reduced size. Thus, the foundation for developing the ultra wideband patch array antennas has been prepared. The fabricated antenna has been found to have good characteristics on V.S.W.R and the radiation patterns over the full bands. The experimental and computed results are shown to be in good agreement.

  • Purpose: This study was based on the Korean Foot and Ankle Society (KFAS) member survey and aimed to report the current trends in the management of syndesmotic injuries over the last few decades. Materials and Methods: A web-based questionnaire containing 36 questions was sent to all KFAS members in September 2021. The questions were mainly related to the preferred techniques and clinical experiences in the treatment of patients with syndesmotic injuries. Answers with a prevalence ≥50% of respondents were considered a tendency. Results: Seventy-six (13.8%) of the 550 members responded to the survey. The results showed that the most preferred method to diagnose a syndesmotic injury was magnetic resonance imaging (MRI). Intraoperatively, the external rotation stress test and the Cotton test were most frequently used to confirm syndesmotic diastasis. The reduction was usually done by a reduction clamp. One 3.5-mm screw was used most frequently over three cortices at 2~4 cm above the ankle joint. The preferred ankle position during fixation was 0° dorsiflexion. Removal of the syndesmotic screw was routinely done by most surgeons, mainly because of the limitation of movement and risk of screw breakage. Factors that affect suture button selection included non-rigid fixation which enables adequate fixation, early weight-bearing, and an infrequent need to remove the hardware. Inadequate reduction was considered the main factor that affects poor prognosis. Conclusion: This study proposes updated information about the current trends in the management of syndesmotic injuries in Korea. Consensuses in both the diagnostic and therapeutic approach to patients with syndesmotic injury were identified in this survey study. This study may raise the awareness of the various possible approaches toward the injury and should be used to further establish a standard protocol for the management of syndesmotic injuries.

  • Purpose. In this study, we aim to clarify the correlation between happiness, appearance, and happiness index among many happiness factors based on the influence of quality of life on the quality of life and the affect of appearance on the happiness index. Methods. We conducted a self - filling questionnaire survey for college students in Busan from March 30 to May 10, 2017, and analyzed 392 copies of the 412 questionnaires, excluding 20 inappropriate copies. In the questionnaire, categorical data were analyzed by frequency and percentage (%) using the SPSS program (ver. 23.0, Chicago, Illinois, USA) by examining 11 items of general characteristics, successive data are presented as mean standard deviation. Results. The higher the grades, the better the dating. Women(3.32) are more likely than men(2.74) at the appearance interest(p>0.001) and the higher the grades, the better. If it's dating someone else, higher than not to do at the appearance interest and all of the questions showed higher interest in appearance. Also there was a high percentage of thought'My life is ideal in all aspects'If it's dating someone else, higher than not to do (p=0.007) Conclusion. At present, There is a high interest in the appearance of dating. In addition, the happiness index according to the current resentment status was higher in both the single item happiness index and the 5 item happiness index, and was significant in the item "My life is ideal in all aspects". Therefore, it is related to the happiness index as well as the appearance interest. Finally, whether or not dating and appearance interest play a role in raising the happiness of the individual.
