Objectives: The aim of this study was to compare the nutritional intake and Diet Quality Index-International (DQI-I) of gynecological cancer survivors and normal women. Methods: This study compared the anthropometric indices, dietary behavior, nutritional intake, and DQI-I in women with previous history of breast or uterine cancer [Gynecological cancer survivors group (GCSG, n=126)] and normal women [Normal control group (NCG, n=7,011)] using the 2013~2016 Korea National Health and Nutrition Examination Survey data. Results: Body mass index and waist circumference were lower in the GCSG compared the NCG. The frequency of skipping breakfast and eating out was higher in the NCG compared to GCSG. Energy and fat intake were significantly higher in the NCG than in the GCSG, whereas intake of all minerals and vitamins (excluding thiamine), and dietary fiber intake were higher in GCSG. It was observed that the fatty acid intake of the GCSG was significantly lower than that of the NCG. The diet quality evaluation using DQI-I results showed that GCSG was higher in the "within-group" diet variety and adequacy of vegetable group than the NCG, whereas the intake level of the fruit group was higher in NCG. Besides, protein, calcium, and vitamin C intake were higher in the GCSG than in the NCG. The GCSG showed higher levels of total fat and saturated fat moderation than the NCG, whereas cholesterol moderation showed the opposite results. The results of DQI-I comparison according to the cancer survival years showed that the overall score and scores related to diet adequacy and balance were higher in the below 5-year group, whereas the over 5-year group scored higher in terms of moderation of diet. Conclusions: The results of this study suggest that a chronic disease based management approach is needed in cancer survivors. The study provides important data which can help in the preparation of guidelines for long-term lifestyle and diet management, in these patients.

Ten recommended rice varieties were cultivated in paddy area affected by air-pollutants and in normal area to select varieties adaptable to air-pollution environment. Rice plants grown in pollution site showed higher contents of total sulfur and fluorine in leaf through the whole growing period compared with those in non-pollution site, and rice leaves destroyed by air-pollutants were found only in pollution site. Rice grain yield and four yield components of ten rice varieties grown in pollution site were lower than those in normal area. Five rice varieties among ten were selected as adaptable to air-pollution environment, based on their yielding potential in pollution site and grain yield ratio between two sites. Rice varieties adaptable to pollution showed little variation of percent ripened grains and number of panicles per hill between two sites. Chlorophyll content in flag leaf of rice plants grown in pollution area was lower than in non-pollution area. No relationship was found between grain yield ratio (pollution/non-pollution site) of ten varieties and total sulfur content ratio, fluorine content ratio, chlorophyll content ratio between two sites, and percent destroyed leaf in pollution site, respectively. This result suggest that varietal adaptability to air-pollution environment is not related with the amount of pollutants absorbed, but with the degree of response to pollutants.

The retinae of Todarodes pacificus and Octopus minor are divided into four layers that are an outer segment, a rod base region, an inner segment, and a plexiform layer, respectively. The retina of Octopus minor is about $20{\mu}m$ thicker ($400{\sim}420{\mu}m$) than that of Todarodes pacificus ($385{\sim}400{\mu}m$). A retina is composed of visual cells and supporting cells. The microvilli of length $0.6{\sim}0.7{\mu}m$ are packed densely on top of the supporting cells of Octopus minor while they are not found in Todarodes pacificus. The visual cells and supporting cells have pigment granules that exclude light. In case of Todarodes pacificus, the pigment granules of the visual cell are larger ($2.0{\times}0.5{\mu}m$) than those of the supporting cell ($1.0{\times}0.3{\mu}m$). But, the sizes of both cells are similar in Octopus minor. In the upper portion of a visual cell, microvilli shaped like a comb are forming a rhabdome (diameter, 60 nm) of a hexagonal structure. The rhabdome consists of 4 rhabdomere and the total area of a rhabdom of Octopus minor is larger than that of Todarodes pacificus. The synaptosome constructing a plexiform layer in Todarodes pacificus are divided into two types, each of which possess electron dense-core vesicles and electron lucent vesicles, respectively. Octopus minor also has two types of synaptosomes but each type comprises a mixture of electron dense vesicles and electron lucent vesicles, and electron lucent vesicles only, respectively, which is different from the case of Todarodes pacificus.

Recently, PC-based control is incredibly developed in the industrial control field, but it is difficult for PLC programming in PC. Therefore, I need to develop the softeware PLC, which support the international PLC programming standard(IECl131-3) and can be applied to diverse control system by using C language. In this paper, I have developed the ISPLC(Intelligent Agent System based Software Programmable Logic Controller). In ISPLC system, LD programmed by a user which is used over $90\%$ among the 5 PLC languages, is converted to IL, which is one of intermediate codes, and IL is converted to the standard C rode which can be used in a commercial editor such as Visual C++. In ISPLC, the detection of logical error in high level programming(C) is more eaier than PLC programming itself The study of code conversion of LD->IL->C is firstly tried in the world as well as KOREA. I developed an execution engine with a good practical application. To show the effectiveness of the developed system, 1 applied it to a practical case, a real time traffic control(RT-TC) system. ISPLC is minimized the error debugging and programming time owing to be supported by windows application program.

Alternative initiation codon(AlC) has been reported in the mitochondrial genes in various mammalian species. We investigated the AlC of mitochondrial NADH dehydrogenase 2 gene(rntDNA ND2) in five pig breeds. Two kinds of initiation codons(ATA/ATf) showing different frequencies among tested pig breeds were used. While all Large White pigs had ATA as an initiator methionine codon, all Landrace pigs had ATf. The other breeds(Berkshire, Duroc and Hampshire) had both initiation codons with the ATA frequencies, 91.9, 21.3 and 60.00/0, respectively. In the previous reports, all Chinese indigenous pig breeds were identified to have unique initiation codon ATA. Although the effect of Ale on the translation of mtDNA ND2 has not been studied in this study, AlC patterns in mtDNA ND2 will contribute to the maternity test using molecular markers in pig breeding.

In this paper, we analyze the performance of the cooperative relay communication system which uses orthogonal frequency division multiplexing(OFDM) with hierarchical subcarrier modulation. In the cooperative relay communication system, data transmission is accomplished in two time slots. In the first time slot, the source broadcasts the signal to the relay and to the destination. The relay demodulates the received signal, remodulates and forwards it to the destination in the second time slot. The source uses hierarchical modulation for subcarriers to deal with the signal-to-noise power ratio (SNR) difference in the source-relay and source-destination links. The bit error rate (BER) of the relay transmission system with hierarchical modulation depends on the hierarchical modulation parameter. First, we derive the relationship between BER and the parameter, and find the optimal parameter giving the minimum BER through computer simulations. Then, we analyze the performance of the proposed cooperative relay communication system according to the relay location. From this results, we find optimal relay location to maximize the BER performance.

Characteristics of reduction properties and carbon deposition of $CuFe_2O_4$ and $Fe_3O_4$ were investigated by using TGA, XRD, SEM, TEM and gas analysis at $900^{\circ}C$. XRD analyses indicated that the reduced $Fe_3O_4$ was composed of Fe, graphite and $Fe_3C$ phases. In contrast, the reduced $CuFe_2O_4$ did not show the graphite or $Fe_3C$ phases. It was observed by SEM analysis that the surface of the $Fe_3O_4$ was completely covered with carbon, after methane partial oxidation. From gas analysis, $CuFe_2O_4$ showed much higher methane conversion and reduction kinetics as compared to the $Fe_3O_4$ under the same reaction conditions and the estimated carbon deposition amounts on the reduced $CuFe_2O_4$ was much lower than those on the reduced $Fe_3O_4$ during the syngas production process. It was found by TEM that carbon on the reduced $Fe_3O_4$ particles has a platelet shape.

The author conducted a records research named 'daily life and records.' The purpose of the research was to find an archive, if possible, that would be effective in promoting exchange and cooperation among people in their daily lives, and to distinguish what type of archive it would be, as well as how to let it naturally take place in their ordinary lives. For 4 months (August-December 2019) with 100 college students in their 20s, trial and error were repeated. There was no separate laboratory for the research, and it used regular school hours at universities. Although it is true that there was a control through power by the college system, the plot was centered on the sunshine policy. To human being there is a voluntary and positive attitude. If anyone begins to take this attitude it is difficult to stop such action. Through emotional support, this voluntary action was encouraged to take root. The experiment was an attempt to doubt the obvious, and to search for something new. From afar, this may seem irrelevant to archives. However, for the author who is a professional archivist, it was a time of records through control by Records principles. By organizing into a form of story, its archival implications are observed.

This test has been carried out to evaluate the effect of temperature on the growth of the insecticide susceptible strain, URY-O nomal genotype and insecticide resistant strain, O-RT abnormal genotype, and ABURABI nomal genotype. The nymphal periods were not significantly different between URY-O and O-RY strains at $25^{\circ}C$. At $30^{\circ}C$, susceptible strain URY-O could give birth to offsprings almost nomally, while resistant strain O-RY could not produce any offspring for 20 days which results in nymphal death. The numbers of offsprings of strain URY-O and strain ABURABI were not different between $25^{\circ}C\;and\;28^{\circ}C$, but strain O-RY, when it was reared at $28^{\circ}C$, could produce offsprings only 10% of those at $25^{\circ}C$. Body weight of strain URY-O and strain ABURABI were 0.22mg/female and 0.27mg/female, respectively at $28^{\circ}C$, however that of O-RY was only 0.16mg/female, showing considerable difference between normal and abnormal genotype. Substrain O-RY(+) which has high esterase activity showed poor reproduction ability(0.8 progenies per $G_{1}$ individual than substrain O-RY(-) (3.4 progenies per $G_{1}$ individual) which has low esterase activity at $28^{\circ}C$
