Objective : This study was aimed to validate the Herbal Acupuncture Therapies(HAT) for cancer patients. Patients and methods : This retrospective study was performed on 8 patients who were diagnosed as cancer in Korea and treated with HAT in the oriental hospital of Daejeon University, from January 2003 to January 2004. We retrospectively analyzed the medical records of 8 patients for improvement of symptoms, toxic effects of liver and kidney, myelosupression and changes of Quality of Life(QOL). Results : Analysis of change of chief complaints showed that 75% patients replied moderate relief and 25% replied complete relief in Likert scale. Analysis of Liver Function Test(LFT), Renal Function Test(RFT) level showed that HAT does not have toxic effects on liver and kidney. Analysis of Complete Blood Count(CBC) level showed that HAT does not have myelosuppression effects on bone marrow. Analysis of QOL showed that 100% patients replied improvement in Eastern Cooperative Oncology Group status(ECOG) status. Conclusion : Our findings suggest that HAT offer potential benefits for cancer patients.

A set of equations of a water transport model of the soil-plant system was described as an electrical circuit using the Ohm's analogy assuming that the transpirational pull be the main source of the driving force and the resistance be proportional to the inverse of the hydraulic conductivity of the catenary. The effective root resistance ($\hat{R}_{\tau}$) and the effective soil water potential ($\hat{\psi}_s$)were defined with the solution of the system; $$\hat{\psi}_s-\hat{R}_{\tau}g_{\tau}={\psi}_0$$ and the validity of the solution of the equation was demonstrated with the data obtained from a soybean field. ${\psi}_s$ and $R_{\tau}$ explained more reasonably than the average values taken so far. Therefore, the solution will describe the soil water status and the root resistance in terms of water transport in the soil-plant system.

Let G = (V, E) be a connected finite graph. We study the existence of solutions for the following generalized Chern-Simons equation on G $${\Delta}u={\lambda}e^u(e^u-1)^5+4{\pi}\sum_{s=1}^{N}\delta_{ps}$$, where λ > 0, δ_ps is the Dirac mass at the vertex p_s, and p₁, p₂, . . . , p_N are arbitrarily chosen distinct vertices on the graph. We show that there exists a critical value $\hat{\lambda}$ such that when λ > $\hat{\lambda}$, the generalized Chern-Simons equation has at least two solutions, when λ = $\hat{\lambda}$, the generalized Chern-Simons equation has a solution, and when λ < $\hat{\lambda}$, the generalized Chern-Simons equation has no solution.

In this research, a design guideline of current generating HAT rotor and acceptable field rotor in offshore environment is proposed. To design HAT rotor model, wind mill rotor design principles and turbine theories were applied based on a field HAT rotor experimental data. To verify the compatibility of the rotor design method and to analyze the properties of design factors, 3 rotor models were designed and experimented in a circular water channel. Three rotor models were designed according to different blade numbers and blade shapes. By changing flow velocity, rotor rpm, the rotor power and efficiency were measured and the properties of rotor were estimated. The results can be effectively applied to the design of current generation rotor.

For the design of wind-power facilities, the highest and lowest astronomical tides (HAT and LAT, respectively) are needed for the tidal-water levels regarding international designs; however, the approximate highest high water and approximate lowest low water AHHW and ALLW, respectively, have been used in Korea. The HAT and LAT in the wind-farm test-bed sea should be estimated to satisfy the international standard. In this study, the HAT and LAT are therefore estimated using the hourly tidal-elevation data of the Eocheongdo, Anmado, Younggwang, Gunsan, Janghang, and Seocheon tidal-gauging stations that are located in the adjacent coastal sea. The nodal variation patterns of the major lunar components, such as $M_2$, $O_1$, and $K_1$ are analyzed to check the expected long-term lunar cycle, i.e., 18.61 year's nodal-variation patterns. The temporal amplitude variations of the $M_2$, $O_1$, and $K_1$ clearly show the 18.61-years periodic patterns in the case of the no-nodal correction condition. In addition, the suggested HAT and LAT elevations, estimated as the upper and lower confidence limits of the yearly HAT and LAT elevations, are 50 cm greater than the AHHW and 40 cm lower than the ALLW, respectively.

The present study was carried out in order to investigate seasonal variation in tannin, sugar and protein contents of persimmon fruits, Five varieties of Diospyros kaki Thunberg, i. e, Buyoo, Wolha, Kapjubackmok, Pyungmuhek, Heuksi, and Goyom (Diospyros Lotus Linne var. typica Makino) growing in Jeonbug area were used as the experimental material. The result are summarized as follow; 1. Maximum tannin contents were 4% in Buyoo, 5.46% in Wolha, 5.4l% in Kapjubackmok, 5.1 % in Pyungmuhek, 9.2% in Heuksi, and 26.1% in Goyom, respectively. Therefore, Heuksi and Goyom were considered to be the most useful as tannin material. 2. The most suitable season for tannin extraction was thought to be July with most varieties but it was August with Goyom. 3. The total sugar contents seemed to increse linearly. Linear regressions are as follows. Buyoo ; $\hat{Y}=0.2394x+3.861$ Wolha ; $\hat{Y}=0.3093x-1.148$ Kapjubackmok ; $\hat{Y}=0.3173x-1.3708$ Pyungmuhek ; $\hat{Y}=0.2796x+0.982$ Heuksi ; $\hat{Y}=0.3233x-3.242$ Goyom ; $\hat{Y}=0.1555x-4.780$ 4. Average crude protein contents of fruits through the year were 5.32% in Buyoo, 4.97% in Kapjubackmok, 4.49% in Goyom, 4.11% in Wolha, 4.02% in Heuksi, and 3.6% in Pyungmuhek, respectively. 5. The crude protein contents tend to decrease gradually after fruit setting.

This study is aiming to set a characteristic design and a fashion trend by analyzing hat style trends and fashion images shown in fashion collections in recent seven years. Also, based on the result of the analysis on the five world's major collections, the influence and the interrelation of hat and fashion image were analyzed. The study was performed by the context analysis method and the image evaluation method. In the context analysis method, the 1,391 pictures for hat-styles which were believed to be the standard of fashion style from the S/S season of 1998 to the F/W season of 2004 were analyzed. The research is summarized as follows. Based on the result of the fashion collections, the kinds of hats came Bowler, Beret, Cloche, Capeline, Cap and Hood in order, and Casual, Feminine, Natural, Formal, Romantic, and Mannish came in order for the case of the fashion images for putting on a hat. The result of the analysis on the characteristic of fashion design according to the kinds of hats, the casual image, with highest frequency, was found from all of the kinds except Capeline. Bowler and Cloche were conspicuous in jackets/slacks, Capeline was conspicuous in one-piece shape, and cloth silhouette showed the highest frequency in H type. As for Bowler, the color of cloth and hat was mostly black, and as for Beret and Cloche, achromatic color showed the highest frequency. But as for Capeline, the cloth color, including chromatic color, was various. As for Beret, pattern and material image were various comparatively, but as for other kinds of hats, there were the materials with no pattern and with hard material image.
