The extension of growing season (GS) across the Northern Hemisphere have been linked to increasing temperature, related with global warming. Therefore, in this study, The start, end, and length of GS in Suwon, Korea from 1971 to 2013 based on observed daily mean air temperature are examined using three indices. The GS starts on average after $98.598.5{\pm}1.42$ Julian days and ends after $318.7{\pm}1.08$ Julian days. The average length of GS is $220.2{\pm}2.09$ Julian days. The length of GS in Suwon from 1971 to 2013 has been extended by 6.8 days/decade with an earlier onset of the GS (-4.1 days/decade) and later end of the GS (2.7 days/decade). This change may be due to an advanced start of the GS in spring rather than later end of the GS. In further study, it is necessary to select an index carefully to find the most suitable one for Korea.

The long-term trend of surface wind speed in Korea is estimated by correcting wind measurements at 29 KMA weather stations from 1985 to 2019 with physical and statistical homogenization. The anemometer height changes at each station are first adjusted by applying physical homogenization using the power-law wind profile. The statistical homogenization is then applied to the adjusted data. A standard normal homogeneity test (SNHT) is particularly utilized. Approximately 40% of inhomogeneities detected by the SNHT match with the sea-level-height change of each station, indicating that an SNHT is an effective technique for reconciling data inhomogeneity. The long-term trends are compared with homogenized data. Statistically significant negative trends are observed along the coast, while insignificant trends are dominant inland. The mean trend, averaged over all stations, is -0.03 ± 0.07 m s^-1 decade^-1. This insignificant trend is due to a trend change across 2001. A decreasing trend of -0.10 m s^-1 decade^-1 reverses to an increasing trend of 0.03 m s^-1 decade^-1 from 2001. This trend change is consistent with mid-latitude wind change in the Northern hemisphere, indicating that the long-term trend of surface wind speed in Korea is partly determined by large-scale atmospheric circulation.

Spinel ferrites (Ni_xFe_3-xO₄; x = 0.25, 0.5, 0.75 and 1.0) have been prepared at 550℃ by egg white auto-combustion route using egg white at 550℃ and characterized by physicochemical (TGA, IR, XRD, and SEM) and electrochemical (CV and Tafel polarization) techniques. The presence of characteristic vibration peaks in FT-IR and reflection planes in XRD spectra confirmed the formation of spinel ferrites. The prepared oxides were transformed into oxide film on glassy carbon electrodes by coating oxide powder ink using the nafion solution and investigated their electrocatalytic performance for OER in an alkaline solution. The cyclic voltammograms of the oxide electrode did not show any redox peaks in oxygen overpotential regions. The iR-free Tafel polarization curves exhibited two Tafel slopes (b₁ = 59-90 mV decade^-1 and b₂ = 92-124 mV decade^-1) in lower and higher over potential regions, respectively. Ni-substitution in oxide matrix significantly improved the electrocatalytic activity for oxygen evolution reaction. Based on the current density for OER, the 0.75 mol Ni-substituted oxide electrode was found to be the most active electrode among the prepared oxides and showed the highest value of apparent current density (~9 mA cm^-2 at 0.85 V) and lowest Tafel slope (59 mV decade^-1). The OER on oxide electrodes occurred via the formation of chemisorbed intermediate on the active sites of the oxide electrode and follow the second-order mechanism.

Miss Pettigrew Lives for a Day, Winifred Watson's novel of 1938, is a fairytale in novel form. Set in London of 1938, the story revolves around a one-day adventure of an ill-starred but truthful governess who is granted a second chance. This light-hearted comedy of manners was turned into a film by director Bharat Nalluri in 2008. An Anglo-American collaboration, co-scripted by Simon Beaufoy and David McGee, the film converts Watson's quaint novel into an edged heritage piece that encapsulates the 1930s, the problematic decade between the two World Wars. The film, while sustaining the narrative core of Watson's Cinderella story, attempts to place it firmly within a wider current of the novel's setting or London in 1938, tapping into the major concerns of the interwar years that engage with characters in one way or another. Stylistically, the film presents Art Deco as a main visual idiom to convey the prevailing mood of nihilism and decadence of the day. The setting here takes on significance in that it offers a telling counterpoint to the giddy superficial world of the novel. The 1930s was a highly charged decade under the threat of fascism and the Great Depression, fraught with economic and socio-political tensions and apprehensions. The film makes an explicit reference to the dismal context which is suppressed in the original text. The thirties is, therefore, portrayed as a decade of contradiction. It features gay buoyant festivity, rampant consumerism, and shifting morals and attitudes towards love, marriage and sexuality. Yet lurking beneath the surface glamour are the symptoms of crises and the deep-seated anxieties on the eve of World War II. In this way, Watson's novel of manners has been recreated into a defining film on the 1930s with its period feel propped by the atmospheric lighting, the exuberant Jazz score, and the splendid Art Deco costume and production design.

The aim of this review is to consolidate findings from clinical investigations spanning the past decade regarding the impact of acupuncture on Parkinson's disease (PD). The objective is to assess the efficacy of acupuncture as a therapeutic approach to PD, with the intention of informing future clinical practices and advancing the foundation for subsequent research endeavors in this area. A comprehensive literature search was conducted to identify clinical trials exploring the effects of acupuncture on PD between January 2014 and August 2023. Databases search included PubMed, EMBASE, CNKI, OASIS, KISS, KMBASE, RISS, and ScienceON. Quantitative evidence from randomized controlled trials (RCTs) was systematically reviewed, and the methodological quality of the included studies was assessed using Cochrane's risk of bias tool. Meta-analysis was performed using Review Manager (RevMan) 5.4.1 software. The systematic review encompassed a total of 38 RCTs involving 2,786 participants. Meta-analysis of 12 studies revealed that individuals treated with a combination of acupuncture and Western medicine exhibited notable improvements compared to those receiving Western medicine alone or sham acupuncture alongside Western medicine. However, the overall quality of the RCTs was deemed low, and no serious adverse events were reported. Across clinical investigations conducted in the past decade, acupuncture appears to hold promise as a complementary treatment for PD patients when administered alongside Western medicine. Nevertheless, this study identifies certain limitations that warrant consideration in future research endeavors. Enhanced emphasis on conducting high-quality RCTs is imperative to comprehensively evaluate the efficacy of acupuncture in managing PD.

A statistical analysis on the cardiothoracic ratio in insurance medicine was carried out for 5,200 insured persons who were medically examined including photofluorography of the chest at the Honam medical department, Dong Bang life insurance Company, Ltd from November, 1979 to August, 1984. The results were as follows: 1. The mean value of the cardiothoracic ratio in all of the insured was $44.2{\pm}4.3%$. The mean value of the cardiothoracic ratio was $43.1{\pm}4.1%$ in all males and $45.2{\pm}4.2%$ in all females, and the difference of the values between males and females showed statistical significance(P<0.001). In each age group, the mean value of the cardiothoracic ratios of female was higher than that of male without exception and the difference of the values between males and females showed statistical significance(P<0.001). The mean value of the cardiothoracic ratio showed gradual increase with age from the second to sixth decade in male(P<0.05 or 0.001 after fourth decade) and from the second to seventh decade in female(P<0.05 or 0.001 from the second to sixth decade). 2. Correlation between both sexes and among age groups relating to the cardiothoracic ratios of the insureds seen to be a physiological phenomenon of the cardiac size and should be considered on the rating of the cardiothoracic ratio. Based on the correlation above mentioned and an author's assumption that the incidence of normal and abnormal cardiothoracic ratios in each age group would show the same rate in male and female, author prepared a modified rating table from the existing table; in male group the existing rating table is used and in female group the ratings of 0, 30-50, 50-100 and 100-D are to calculate by the cardiothoracic ratio of 51%or under, 52-56%, 57-61% and 62% or over respectively in the age group below 39, by the cardiothoracic ratio of 52% or under, 53-57%, 58%-62% and 63% or over respectively in the age group of 40-49, by the cardiothoracic ratio of 53% or under, 54-58%, 59-63% and 64% or over respectively in the age group over 60. 3. The relative frequency distribution polygons of the cardiothoracic ratio of both sexes drawn in a pair on one coordinate plane revealed lying in juxtaposition each other horizontally and showed the shifting of females polygon to male's one toward the direction of greater value of the cardiothoracic ratio at a short distance which increased gradually with age. 4. The minimum cardiothoracic ratio was 31.2% and the maximum cardiothoracic ratio was 63.6% in all of the insured. 5. In each age group, no significant sex difference was found in the relative frequency distribution of ratings by the cardiothoracic ratios of 5,200 insureds by using the rating table modified by author, while significant sex difference was found by using the existing rating table.

This study was carried out to identify basic data for more efficient operation of comprehensive health check-up centers in the national health care system. The researcher reviewed and analyzed the main symptoms of the subjects according to sex, age, occupation and positive rate in the screening tests of a comprehensive health check-up, performed at one comprehensive health check-up center in located in a hospital. The subjects were 512 persons who had a check-up at the comprehensive health check-up, center in K university hospital in Seoul from October 2, 1996 to March 30, 1997. A questionaire developed by the researcher to obtain subject's general characteristics, main symptoms, medical examination, diagnosed disease was used as the tool for the study. The researcher analyzed the data with SPSS PC/sup +/ program. : the distribution of the subject's general characteristics and main symptoms was described with percentages and the difference between main symptoms and screening tests analyzed with X²-test, t-test, ANOVA. The result of this study are as follows : 1. For the distribution of diagnosis in males. liver disease was most frequent and hypertension was second : in females, hypertention and liver disease were not common in that order. 2. The most common complaints were indigestion in the digestive system, sputum in the respiratory system, irregular heart beat in the cardiovascular system, frequent urine in the urinary system vertigo in the hematologic system. 3. The main symptoms according to sex were for females, a statistically siguificant higher rate of complaints in the digestive system, cardiovascular system, urinary system, hematologic system, musculoskeletal, mental & nervous system as compared to males. 4. The main symptoms according to age were that in the the second decade there wara higher rate of complaints in the digestive system, and cardiovascular system than in the older age groups : and in the fifth decade more in the musculoskeletal system. 5. The main symptoms according to occupation were that formers and fishers had a higher rate of complaints in the mental and nervous system as compared to other occupation groups : and office workers, in gynecology. 6. The main symptoms according to diagnosis, were symptoms of the digestive system, frequent in liver disease : symptoms of the cardiovascular system in allergic disease. 7. The screening tests which showed the highest rates were UGI /FGS, PFT : In males a higher rate of abnormality was seen in abdominal ultrasono- graphy and in, females, in mammography. 8. In screening tests according to sex, males showed a higher positive rate for chest X-rays, and LFT, and females, in mammography, pap smear, CBC. 9. In screening tests according to age, higher positive rates of obesity, high blood pressure, chest X-ray, mammography, pap smear, FBS, CBC, urine test were seen in the fifth decade : PFT and abdominal ultrasonography in the third decade. The subjects who wanted comprehensive health check-up were not asymptomatic but had an illness with several symptoms. It is found that the most frequent diagnosed diseases were hypertention and liver disease. So proper observations must be done for them. Comprehensive health check-ups should be changed to a comprehensive examination including treatment beyond examination for those subjects with positive results.

Neck mass as a primary presenting sign is a common problem that physicians and surgeons alike have to face but conclusive diagnosis cna be made only by histopathological examination. During the period of four years from January 1988 to December 1991, three hundred sixteen diagnostic incisional or excisional biopsies of the neck masses were performed at the outpatient department of Surgery, Seoul National University Hospital and tissue diagnoses were confirmed by histopatholotical examination. On which a clinical analysis was performed and its results were compared with the results of one hundred fifteen Fine Needle Aspiration Cytologic examinations on neck masses during the same period. The results were as follows: In the histologic types of neck masses. inflammatory disease was the most common (58.2%), metastatic malignant tumor(22.5%), benign tumor(15.2%). primary malignant tumor(0.4%) in decreasing order. Among the individual lesions. tuberculous lymphadenitis was the most common(29.4%) and nonspecific lymphadenitis was the next. Of overall sexual distribution, female preponderated by a ratio of 1.15:1, but in the primary and metastatic malignancies, male did by a ratio of 1.60:1 and 1.53:1, respectively. The most common age group was third decade(26.8%), and fourth decade was the next(20.9%) but in malignant tumors. sixth decade was the most commom. The duration of symptom between one and three months(33.8%), was the most common and between three and six month was the next but the difference between the individual diseases was not significant. Of the metastatic tumor of seventy one cases, primary site was found in fifty cases(84.2%) and stomach cancer was the most comon primary site. In the result of the Fine Needle Aspiration Cytologic(FNAC) examinations, positive for mlignant cells was the most common(33.1%), following the frequencies with tuberculosis(22.6%), and nonspecific lymphadenitis(16.5%) in decreasing order. Eleven cases of FNAC underwent diagnostic biopsies and the diagnostic accuracy of FNAC was 83.3%. Conclusively, in our study, tuberculous lymphadenitis was the most common histologic type, female was predominant third decade was the most common age group. the duration of symptom between one and three month was the most common and in the metastatic tumors, stomach cancer was the most common primary site.
