The aerodynamic resistance($R_a$) to vertical transfer in the surface boundary layer can be formulated in terms of the friction velocity, height of observation, vertical heat flux and surface roughness. Unlike previous studies which focused on the role of $R_c$, present study perform additional tests using a variety of $R_a$ formulae. Several $R_a$ formulations available in the literature, suitable for unstable conditions, were tested for their influence on the dry deposition velocity. The canopy resistance($R_c$) determines the shape of the diurnal pattern, while a small amplitude diurnal cycle in $V_d$ was attributed to the aerodynamic resistance. The aerodynamic resistance is the major contributor to the formation of spikes in nighttime and $R_a$ is relatively important at night because the canopy resistance is smaller. All formulations show similar diurnal cycle and yield good agreement with the observations. Although present $V_d$ formulations are suitable for numerical air qualify models, the research must continue for further improvements in resistance parametrizations.

Objectives : Actually Wongi did not exist in "Neijing(內經)" as a word. Wongi is one of specific features that distinguish "Nanjing" from "Neijing". I have researched for the foundation of history and thought. Methods : I have looked into cognitive variation for Heaven (天), that is from Chinese ancient times through the period of the Han (漢) Dynasty. Results : 1. Before the period of the Yin (殷) Dynasty : There was some worship. 2. The period of the Yin Dynasty : The Lord (上帝) was respected and idolized. 3. The period of the Zhou (周) Dynasty : That the origin of existence is also in human was recognized through Doctrine of Heaven (天命思想). 4. The period of the Han Dynasty : Doctrine of Heaven was transfigured as ideological instrument for politics. The spiritual and physical human's independence was flowed into even though it was not separated from Heaven. Conclusions : As concerned above, the variation shows that consideration for the origin of existence flowed from the outside of human being, like the progenitor of human race, nature, and Heaven, through inside gradually. In the other words, the origin of existence was come to inquire inside of human being. As an aspect of medical science, it can be showed that the term of Wongi was influenced of these process.

The theory of Hwa Acupuncture Therapy (HAT), called Hwa Chim Therapy, is a part of the Five Elements Theory unique to Korea. HAT, created and developed by Jaehoon Song, integrates the victor-vanquished as well as the son-mother relationship of the Five Elements of breakdown and restoration of balance between yin and yang. And also, it provides resources and data on The seventy fifth Difficulty(75難) of Classic on Difficulty - Nan Jin 75. HAT establishes objectiveness and accuracy of diagnosis based upon the traditional method and procedure of pulse taking. In HAT, a person's state of illness is diagnosed by applying the comparative examination of the palpitation of the pulse. It is fact that the pulse varies according to the state, and that HAT treatment has proven the positive results by using the victor-vanquished relationship of Classic on Difficulty-Nan Jin 75. Despite a concise and simple theory, Hwa Chim is very effective in treating a wide range of illnesses, and thus it has gained an increasing attention of many scholars and practitioners in the field of traditional Korean oriental medicine. However, it is the first theoretical attempt to the clinical research and scientific methodology of Ohaeng Hwa Chim, and more active Hwa Acupuncture R&D is being conducted nationwide.

This present study tried to observe an each feature that the difference of Neijing(內經) and Nanjing(難經) descriptions about the three-portion and nine-position pulse taking(三部九候脈). It was interpreted and contradistinguished that discrimination of position, diagnosis object, and the perceptions of Earth of the center among the Five Phase of each literature were described in Neijing and Nanjing for the three-portion and nine-position(三部九候). In Neijing, the three-portion and nine-position method divided three parts the whole body. Then the each three parts again divided with Heaven, Earth and Man(天地人). About the corresponding parts of pulse diagnosis, there mentioned for the head and the Zang-Fu organs(臟腑), but not mentioned for the hand and foot. In addition, Earth is assigned to the Earth(土), an each Earth accounted for the source of life. In Nanjing, three-portion divided Chon, Gwan, and Cheok(寸關尺) and each spots separated three stage of pulse taking. For the pulse taking spots and diagnosis, there mentioned the hand and foot instead of the unclear mention of Zang-Fu organs. Then Gwan spot and middle stage of pulse taking were assigned to the Earth, respectively. It was emphasized stomach Qi(胃氣) that the region of Earth, Gwan spot and middle stage among the pulse taking spots each literature were described in Neijing, Nanjing.

Referred to "Jeungchijunseung(證治準繩" ), "Kyungakjunsu(景岳全書)", and "Uihakyipmoon(醫學入門)", We got the conclusion on the contradiction of KwanKyuk in "Naegyung(內經)" and "Nankyung(難經)" like below. First, It can be defined the fact as Naekwanoikyuk(內關外格) in "Nankyung(難經)" that in "Naegyung(內經)", the Cold from out is too strong that the Yanggi is isolated and vomitted and spread to Hacho(下焦). Because, it is the same phenomenon in "Nankyung(難經)", Yanggi is too strong that invade the stage of Eumgi, and in the flow, overturning situation appears and thru isolation. Same above, We can also understand the fact as Oikwannaekyuk(外關內格) in "Nankyung(難經)" that the Ileum(溢陰, same as Naekwan(內關) or Kwaneum(關陰) in "Naegyung(內經)" ), Heat from Mixed disease(雜病) is too strong that Eumgi is isolated and spreading to Sangcho(上焦). Because, it is the same phenomenon in "Nankyung(難經)" , Eumgi is too strong that invade the stage of Yanggi, and in the flow, overflowing situation appears and thru vomitting.

We investigated the changes in the egg diameter of chub mackerel Scomber japonicus with the stages of egg development (and distinguished between hydrated oocyte and non-hydrated oocyte) for 1, 2, 3, 5, 10, 15 and 30 days. The chub mackerel oocytes were preserved in seven fixing solutions (70% ethyl alcohol, 99.9% ethyl alcohol, 5% formalin, 10% formalin, 5% neutral buffered formalin, 10% neutral buffered formalin and Gilson's solution). At 30 days, the chub mackerel hydrated oocytes preserved in 70% ethyl alcohol and 99.9% ethyl alcohol had shrunk by 5.2% and 7.9%, respectively. Similarly, the non-hydrated oocytes in the same solutions shrunk by 10.3% and 14.0%, respectively. Oocytes preserved in Gilson's solution had an average egg diameter decrease in both the hydrated oocyte (by 16.9%) and non-hydrated oocytes (by 15.6%). The diameter of the preserved hydrated oocytes did not significantly differ between the 5% formalin, 10% formalin, 5% neutral buffered formalin and 10% neutral buffered formalin, with shrinkage percentages of 0.6%, 0.1%, 1.9% and 3.4%, respectively (P>0.05). Similarly, the shrinkage percentages of the non-hydrated oocytes were 4.3% (5% formalin), 5.5% (10% formalin), 4.3% (5% neutral buffered formalin), and 4.1% (10% neutral buffered formalin).
