Electron microscopy analysis of soft materials with freeze-fracture techniques

김완태,윤동기 대한화학회 2023 Bulletin of the Korean Chemical Society Vol.44 No.2

Electron microscopy (EM) is a technique that observes the complexmicrostructure of a sample with a resolution of several Å using high-energyelectrons with a short wavelength. It is very effective for visualizing nanostruc-tures that would not be observed with an optical microscope. However, thereare limitations in that the observation must be carried out with a very thin filmin a vacuum, and the electron beam may damage the samples. The samplemay be out of the desired state or damaged, and the image may be distorted.As a solution to these problems, a freeze-fracture technique can be proposed.Freeze-fracture method is a process of rapidly freezing a sample and then frac-turing it to produce a metal replica of the morphology of the bulk of the sur-face. This article includes an overview and principles of freeze-fracturetechniques and examples of analysis of various soft structures

Korea and Japan have exchanged a lot from old times and they are close to each other geographically and have a lot of common things also in religion such as Confucianism and Buddhism. So it needs to understand the attitude toward the aged in both countries because both countries have the similar issues like aging speed as well as the similarity in social and cultural situation. In preparation for the aging society, it needs to compare the attitude toward the aged in both countries and to find if there is a difference between the two countries and what kind of variables were adapted in order to renew the positive awareness about the aged and to explore the direction to provide the chance of interaction between generations. For this purpose, the survey was conducted for 180 Korean college students and 190 Japanese college students who major in social welfare. The main results of this research are as follows. First, regarding the social demographic characteristics and the comparison of the attitude toward the aged, there was a significant difference only in Korean subjects. That is, in case of the students who had no religion and had experienced volunteer works, the attitude toward the aged was more positive. And also in the comparison of the attitude toward the aged according to their knowledge about the aged, there was a significant difference only in Korean subjects. That is, the attitude toward to the aged was more positive as the knowledge about the aged became higher (F=4.70, p<.05). Second, regarding the knowledge and attitude toward the aged, as for the correct answer rate of the knowledge about the aged, in case of Korea, the average point was 12.09 ± 0.20 out of 24 and the average correct answer rate was 50.39%, and in case of Japan, the average point was 10.57 ± 3.07 and the average correct answer rate was 44.08% which was lower than the case of Korea. Regarding the attitude toward the aged, it was 84.33 out of 140 in case of Korea. That was in the neutral range but lower than the Japanese point of 87.92, which means the Korean attitude is more negative than Japanese.

Recently the use of personal mobility devices is rapidly increasing, and the businesses related to personal mobility devices are quickly growing as well. Although the use of personal mobility devices provides convenience for short distance movements, many problems occur due to the lack of safety devices and the absence of associated road traffic laws. The number of accidents caused by using personal mobility devices continues increasing every year, and the injuries or deaths are seriously happening with those accidents. When using personal mobility devices, there are basic safety precautions such as wearing a helmet, prohibiting boarding with more than two people, prohibiting boarding with more than 100kg, prohibiting using after drinking alcohol, and so on. However, it is exposed to traffic accidents because there is no way to check before using the system. Therefore, to ensure the user's safety in using the electric kickboard among personal mobility devices, this paper proposes a system that can check the user's safety state before using the electric kickboard. It is possible to safely use personal mobility devices and prevent accidents by proposing a system structure of the electric kickboard that can be used after checking for the use of more than two people, overweight, wearing a helmet, and drinking alcohol.

Experiments were performed to elucidate some aspects of the diuretic effect showed by alcoholic beverages. Fifteen healthy male students in the early twentieth were divided into three groups and induced the changes in the volume and the osmolar concentration of the extracellular fluid. The first group (water group) ingested 100ml of water ; the second one (Soju group) ingested 160ml of Soju(containing 25% of ethyl alcohol), Korean distilled spirits ; the third one (beer group) ingested 1000ml of beer (containing 4% of srhanol). Urine was collected every 30 minutes. Urinary, osmolartity and the excretion of sodium chloride were measured. And blood was sampled to measure blood alcohol level in Soju and beer groups. The results were obtained as followings : 1) The water group showed that the urinary flow begins to increase sithin 30 minutes and reached its peak at 30 minutes after he ingestion of water. The total volume excreted flow volume. And the condition of body fluid was suggested to recover to the normal control state sithin three hours. 2) The Sohu group showed that the urinary flow begins to increase as rapid as one in the water group and reached its peak at 90 minutes after the start of the experiment. The total volume excreted for three hours exceeded about 80ml over the sum of the ingested amount(160ml) and the control urinary flow (126ml). It was infered that the body fluid of this group showed the relative dehydration after the three hour experiment. And it was suggested but could never be concluded that the phenomena be due to the effect of some additives which were excreted slowly. 3) The beer group showed the very strong diuretic phenomena and eventual mild dehydration phenomena, which were suggested to be both the effect of alcohol itself in beer and the action of water contained in beer. 4) From the above results, it may be concluded that the diuretic effects of alcoholic beverages be due to some additives and water component in berverages as well as alcohol itself.
