Present Saam acupuncture can be divided into two types of Therapeutic part that is composed of physiology, pathology, classification of the symptoms, treatment and Experiential part that is composed of clinical case. Therapeutic part is authored by Saam and experiential part is authored by Ji-san. Experiential part is based on therapeutic part, but it has been changed. So, Measuring "chapter10. Saam acupuncture(apply to therapeutic part)" against "chapter11. Clinical case of Ji-san(apply to experiential part)", Author get to know that experiential part of Saam acupuncture has been changed. "chapter10. Saam acupuncture(apply to therapeutic part)" and "chapter11. Clinical case of Ji-san(apply to experiential part)" belong to "TaeHanUiHakJeonJip Acupuncture part" that is similar to manuscript of Saam acupuncture. The following is changed situation of Saam acupuncture. First, While the theory of Jeong form is already established in therapeutic part, the theory of Seung form is established in experiential part. So, In experiential part, they are equal in their relations. Second, In experiential part, the term that is named 'prescription of ${\bigcirc}{\bigcirc}$' has been used since experiential part. Third, Some of spots on the body suitable for acupuncture mentioned in therapeutic part are omitted in experiential part. And to conclude, experiential part play a large role in the establishment and change of early Saam acupuncture.

Objectives : In order to make a new psychotherapeutic model in the theory of oriental medicine by means of psychoanalysis method. Methods : The research was done by comparing the contents of the Tong-Ui Po-Kam, techniques of Yang Saeng(養生術), with the psychoanalysis Results : 1. There's no difference in the mind state which a doctor has to have between the oriental doctor and the occidental doctor. You should make effort not to project yourself on a patient. A conception of 'doctor' in oriental medicine is one who trains one's mind rather than just healer. 2. Heart(心) in oriental medical conception is revealed by circulation structure of Jeong(精), Gi(氣), and Sin(神). A healthy mind comes from harmony and smooth transport of Jeong(精), Gi(氣), and Sin(神). 3. The conception similar to unconsciousness doesn't exist in oriental medicine, but the contents about the attitudes or the methods of training one's mind correspond to unconsciousness. 4. The psychotherapy of oriental medicine emphasized mutual dynamics between emotions at present, and presented a way of treatment by describing emotions from standpoint of 'Gi(氣)' 5. The special feature of psychological treatment in oriental medicine is that treatment is done by understanding emotions of present time as Gi(氣), and using dynamics of Gi(氣)(; 相生相剋). Also the balanced state can be kept even after treatment and prevention can be done by observing one‘s own unconsciousness(; training one's mind helps circulation of Jeong(精), Gi(氣), and Sin(神)) I think that we need a new realistic therapy model to develop these psychotherapy methods in oriental neuropsychiatry, through studying emotions in the theory of oriental medicine, especially Korean's emotions and spiritual training.

Cloud droplet activation process is well described by $K{\ddot{o}}hler$ theory and several parameterizations based on $K{\ddot{o}}hler$ theory are used in a wide range of models to represent this process. Here, we test the two different method of calculating the solute effect in the $K{\ddot{o}}hler$ equation, i.e., osmotic coefficient method (OSM) and ${\kappa}-K{\ddot{o}}hler$ method (KK). To do that, each method is implemented in the cloud droplet activation parameterization module of WRF-CHEM (Weather Research and Forecasting model coupled with Chemistry) model. It is assumed that aerosols are composed of five major components (i.e., sulfate, organic matter, black carbon, mineral dust, and sea salt). Both methods calculate similar representative hygroscopicity parameter values of 0.2~0.3 over the land, and 0.6~0.7 over the ocean, which are close to estimated values in previous studies. Simulated precipitation, and meteorological variables (i.e., specific heat and temperature) show good agreement with reanalysis. Spatial patterns of precipitation and liquid water path from model results and satellite data show similarity in general, but on regional scale spatial patterns and intensity show some discrepancy. However, meteorological variables, precipitation, and liquid water path do not show significant differences between OSM and KK simulations. So we suggest that the relatively simple KK method can be a good alternative to the OSM method that requires various information of density, molecular weight and dissociation number of each individual species in calculating the solute effect.

Object : From the ancient times, the importance of childbirth has been well recognized by Korean Traditional Medicine. Numeral methods have been developed to ease the labor process and keep the mother and child healthy from conception to labor. Bulsusan(佛手散) is one of the main remedies to healthy labor in KTM, both widely known and applied as well. Method : This paper examines the labor theory and practice of KTM focused on Bulsusan which is composed of Angelica gigas Nakai(當歸) and Cnidium officinale MAKINO(川芎). Result : 1. From the ancient times until the Q$\bar{i}$ng period, much attention was placed to the handling of the placenta, as it was conceived as bearing much relation to the health of the mother and her fate, and thus included in the labor process. 2. There was a recognition of the 'birth pulse[離經脈]', an intense change in the pulse that presents itself prior to somatic signs of labor. 3. There were numerous prescriptions that were administered beforehand to ease the process. They are mostly constituted with medicinals that nurture Gi(氣) and stimulate its flow, which in turn makes the fetus firm and reduces the volume, easing the labor process. 4. The medical practice of labor-induction was called 'Choesaeng(催生)'. The prescriptions which functioned as such were mostly constituted with blood medicinals such as Angelica gigas Nakai and Cnidium officinale MAKINO, those which nurture both Gi(氣) and blood, and medicinals that physically lubricate the labor pathway such as honey, oil and Talcum(滑石). Conclusion : Bulsusan can be used in most problems concerning pregnancy and labor, and cases of emergency blood loss due to injury. The term 'bulsu(佛手)' infers to the medical ability of the great doctor who takes care of major blood-loss situations resulting from discharge of dead fetus, cesarean delivery, etc. The prescription name takes after this meaning, as it deals with similar conditions in its effect.

Using the computer programs for calculation of natural vibrations of ship's hull developed by the authors et al., an investigation into influences of various parameters on the accuracy of calculation was done through example calculations of a 30,000 DWT petroleum products carrier M/S Sweet Brier built by Korea Shipbuilding and Engineering Corporation. The methodical principles employed for the computer program development are as follows; (a) the ship system is reduced to an equivalent discrete elements system conforming to Myklestad-Prohl model, (b) the problem formulation is of transfer matrix method, and (c) to obtain solutions an extended $G\ddot{u}mbel's$ initial value method is introduced. The scope of the investigation is influences of number of discrete elements, choice of significant system parameters such as rotary inertia, bending stiffness and shear stiffness, and simplification of distributions of added mass and stiffness as trapezoidal ones referred to those of midship section on the calculation accuracy. From the investigation the followings are found out; (1) To obtain good results for the modes up to the seven-noded thirty or more divisions of the hull is desirable. For fundamental mode fifteen divisions may give fairly good results. (2) The influence of rotary inertia is negligibly small at least for the modes up to the 5- or 6- noded. (3) In the case of assuming either bending modes or shear modes the calculation results in considerably higher frequencies as compared with those based on Timoshenko beam theory. However, the calculation base on the slender beam theory surprisingly gives frequencies within 10% error for fundamental modes. (4) It is proved that to simplify distributions of added mass and stiffness as trapezoidal ones referred to those of midship section is a promising approach for the prediction of natural frequencies at preliminary design stage; provided good accumulation of data from similar type ships, we may expect to obtain natural frequencies within 5% error.

This study is to analyze the impedance response in human body by acoustic stimulation on acupoints and contrast parte; for objectification of the meridian substance. It is to verify meridian pathway and channel theory or bio-energy in body. This paper proposes to make an hypothesis about the underground water theory. The meridian has not tube or pipe line type channel but bio-energy flow along the channel similar to flowing pattern of underground water in body. It was analyzed the current characteristic or impedance response after acoustic stimulation by sound wave of 5 specific tones. The response characteristics of current stimulation are measured by the average current magnitude and variation ratio or meridian. The current variation ratio or Live Meridian(gung) 33.2%, Heart Meridian(sang) 30.7% Kidney Meridian (gak) 33.1%, Spleen Meridian(chi) 33.9%, Lung Meridian (wo) 30.7% are to be compared to contrast parts (non-acupoint and meridian). In experimental results, meridian is discrimination to non-meridian, and 5 vital meridians have a reciprocal relationship with sound wave of 5 specific tones.

Significant structure theory was applied to some liquid mixture systems ranging from simple monatomic molecule systems to polyatomic molecule systems, and the activity coefficients ${\gamma}$ of the liquid mixture systems were calculated over whole mole fractions using the following thermodynamic relation $RTln_{{\gamma}i} = (\frac{{\partial A}^E}{{\partial N}_i})_{T,V,N_i} $ where $A^E$ represents the excess Helmholtz free energy, and $N_i$ is the number of molecules of component i. The activity coefficients of the solutions such as monatomic molecule systems (Ar-Kr, Kr-Xe) and diatomic molecule systems $(Ar-O_2,\;N_2-CO)$ and $CH_4-Kr$ systems whose components have similar shapes for intermolecular potential curves were calculated successfully only with the ${\delta}E_s$, correction parameter for energy $E_s$, for mixture systems. For other systems such as $Ar-N_2,\;O_2-N_2\;and\;CH_4-C_3H_8$ whose components have dissimilar intermolecular potential curve shapes an additional correction parameters ${\delta}$V and even one more parameter ${\delta}$n were necessary [see Eqs.(10)∼(12)].

For maintaining adequate psychometric properties when reducing the number of items from an instrument, item level psychometrics is crucial. Strategies such as low item correlation or factor loadings, using classical test theory, have traditionally been advocated. The purpose of this study is to describe the development of a new short form assessing the impact of low back pain on physical activity. Rasch measurement model has been applied to the International Classification of Functioning, Disability and Health Activity Measure (ICF-AM). One hundred and one individuals with low back pain aged 19-89 years (mean age: $48.1{\pm}17.3$) who live in the community were participated in the study. Twenty-seven items of lifting/carrying construct of the ICF-AM were analyzed. Ten items were selected from the construct to create a short form. Item elimination criteria include: 1) high or low mean square (out of the range: .6-1.4 for the fit statistics), 2) similar item calibrations to adjacent items, 3) person separation value, and item-person map for potential gap in person ability continuum. All 10 items of the short form fit to the Rasch model except one item (i.e., carrying toddler on back). Despite its high infit and outfit statistics (1.90/2.17), the item had to be reinstated due to potential gaps at the upper extreme of person ability level. The short form had a slightly better spread of person ability continuum compared to the entire set of item. The created short form separated individuals with low back pain into nearly 4 groups, while the entire set of items separated the individuals into 6 groups. The findings prompted multidimensional models for better explanation of the lifting/carrying domain. The item level psychometrics based on the Rasch model can be useful in developing short forms with rationally retained items.

This study aimed to develop an approach to accurately predict the wind models and wind effects of large wind turbines. The wind-induced vibration characteristics of a 5 MW tower-blade coupled wind turbine system have been investigated in this paper. First, the blade-tower integration model was established, which included blades, nacelle, tower and the base of the wind turbine system. The harmonic superposition method and modified blade element momentum theory were then applied to simulate the fluctuating wind field for the rotor blades and tower. Finally, wind-induced responses and equivalent static wind loads (ESWL) of the system were studied based on the modified consistent coupling method, which took into account coupling effects of resonant modes, cross terms of resonant and background responses. Furthermore, useful suggestions were proposed to instruct the wind resistance design of large wind turbines. Based on obtained results, it is shown from the obtained results that wind-induced responses and ESWL were characterized with complicated modal responses, multi-mode coupling effects, and multiple equivalent objectives. Compared with the background component, the resonant component made more contribution to wind-induced responses and equivalent static wind loads at the middle-upper part of the tower and blades, and cross terms between background and resonant components affected the total fluctuation responses, while the background responses were similar with the resonant responses at the bottom of tower.

Software complexity is used to evaluate a target system's maintainability. The existing complexity metrics on web applications are count-based, so it is hard to incorporate the understandability of developers or maintainers. To make up for this shortcomings, entropy-theory can be applied to define complexity, however, it is assumed that information quantity of each paper is identical. In this paper, structural complexity of a web application is defined based on information theory and similarity. In detail, the proposed complexity is defined using entropy as the previous approach, but the information quantity of individual pages is defined using similarity. That is, a page which are similar with many pages has smaller information quantity than a page which are dissimilar to others. Furthermore, various similarity measures can be used for various views, which results in many-sided complexity measures. Finally, several complexity properties are applied to verify the proposed metric and case studies shows the applicability of the metric.
