This study was to explore on the rank of stressful events related to the experience of hospitalization. 180 hospitalized patients on surgical and medical wards were asked to rate 49 stress-producing events associated with the experience of hospitalization. Two university hospitals was used as the setting for this study. Because the nature of the events in the stress scale pertain mainly to general short term hospitalizations, patients in the rehabilitation and psychiatric units of the hospital were not included. Prior to the beginning of the study, three times meeting were held with 12 head nurses and 3 investigators for discussing with the ethics subject related to the study. The pretest was done to determine whether items to use were pertinent or not. According to the result of the pretest, Volicer's Hospital Stress Rating Scale was selected as a study tool for this study. Data collection was used an interview and a card-sorting method. The interviewing was done by two authors and three graduate nursing students. A total 125 completed the card-sorting procedure. The stressful items were ordered from most to least stressful within the categories. Additional information such as: age, sex, marital status, and diagnosis was obtained from the kardex file. The ordered list of items, with mean values, as scored by the total of 125 respondents was significantly accepted at 1% level by Friedman test. (X²=1448.339) The event,“knowing you have a serious illness.”was rated highest stressful and (M=41.54) “Being awakened in the night by the nurse”least stressful. (M=14.73) Highly rated items were orderly “Thinking you might have cancer”“Thinking you might lose a kidney or some other organ”“Not being told what your diagnosis is. “Not knowing for sure what illness you have,”five lowerly rated items were orderly “Having to eat at different times than you usually do”“net being able to call family or friends on the phone”“Not having friends visit you,”“Having strangers sleep in the same room with you.”Futher analysis of the data was done to ascertain tao degree of similarity of judgment between different groups in the sample as to how events should be rated. The sample was divided into two groups according to the demographic characteristics and the degree of seriousness of illness. The rank order correlation was calculated for the two sets of ranks as a measure of consensus between the two groups. The correlations ranged from .85∼.99 all indicating a high degree of consensus.
Purpose : The purpose of this study was to evaluate the results of arthroscopic meniscal repair according to joint stability. Materials and Methods : Twenty cases were reviewed, which had underwent arthroscopic meniscal repair. The mean age was 32.3 years old. The mean follow-up period was 59.7 months. Menisci that had underwent complete repair of associated ligament injuries (8cases, Sa) and menisci that had no associated ligament injury (9 cases, Sb) were classified as stable group (S), and the others (3 cases) as unstable group (U). Also stable group was divided into acute and chronic group. The result was evaluated with Lysholm score and IKDC method. The statistical analysis was done using Wilcoxon rank sum test and Fisher's exact test (p<0.05). Results : Group Sa had $87.5\%$ satisfactory and Lysholm score was 90.9. Group U had $66.7\%$ satisfactory, and Lysholm score was 77.7. Group Sb had $89.9\%$, satisfactory and Lysholm store was 91.4. In acute group $91.7\%$ was satisfactory, Lysholm score 92.5, in chronic group $80\%$ was satisfactory, Lysholm score 88.6. Conclusion : Joint stability was important factor for the outcome of meniscal repairs. So, it is desirable to repair meniscus injury early and the repair of associated ligament injuries should be performed together.
The purpose of this study was to propose a brand image profile by analyzing how the consumer perceived the rival brands having relative structure between corporate image, store image, and. product image. Fifty-two questions were prepared for the respondents, and 262 questionnaires were selected for analyzing. The data were analyzed by a frequency, a mean, a reliability, and a paired t-test of the SPSS 12.0. The results were as follows : 1. As influence rank of the brand image, a product image had greatest influence followed by a store image and a corporate image. 2. The factors, which were regarded as important from consumer, and satisfaction of those factors were evaluated. As a result of the analysis, the degree of satisfaction of the factors was relatively low than that of the importance. It was proved that the important factors of the brand's image and the degree of satisfaction of the factors were not the same from this study.

The goal of this paper is to analyze the performance of a word autocomplete system for mobile devices such as smartphones, tablets, and PCs. The proposed system automatically completes a partially typed string into a full word, reducing the time and effort required by a user to enter text on these devices. We collect a large amount of data from Twitter and develop both unigram and bigram dictionaries based on the frequency of words. Using these dictionaries, we analyze the performance of the word autocomplete system and devise a keystroke profit rate and recovery rate as new evaluation metrics that better describe the characteristics of the word autocomplete problem compared to previous measures such as the mean reciprocal rank or recall.

Variation in construction means modification of design, changes in quality, quantity of work including the alteration of standard of materials or goods to be used in the work and the removal from site any kind of material not in accordance in the contract. In Ghana, Variation order has become major issue in the construction industry. This had resulted in cost overruns, delay and in some contracts dispute, between parties. The aim of this paper was to identify the root causes of variation; effects of variations on projects in Ghana and the means of reducing the impact of variation order. The method of the study involved literature review, primary data collection, interview and closed - ended- questionnaires. Mean Scores Method was used to rank the identified factors causing variation. Analysis Of Variance Test was use to test for the significant difference between means among the professional groups. The study revealed that most causes of variation were change of design by client and inadequate working details. Establishment of oversight project management committee and flow of information were identified as means of controlling variations during project administration.

The purpose of this study was to provide a 360-degree video on intensive care unit admission guidance to family members admitted to the intensive care unit, and then to identify anxiety, safety perception, and satisfaction. This study was a single-group pre-post design, and the data collection period was from October 1, 2020 to August 30, 2021. The subjects of this study were 19 people who applied 360 degree hospitalization guide video. For data analysis, SPSS WIN 24.0 program was used, and real number, percentage, mean, standard deviation, minimum value, maximum value, and Wilcoxon signed rank test were used. The subjects' anxiety before intervention was an average score of 6.21±2.30 and the anxiety after intervention was an average score of 3.95±2.46, which was statistically significant (z=4.13, p<.001). The safety consciousness of the subjects before the intervention was an average of 4.08±0.39 and the safety consciousness after the intervention was an average of 4.54±0.48, which was statistically significant (z=5.00, p=.001). The highest level of satisfaction with the 360-degree hospitalization guidance image of the subjects was 4.58±0.51 and the lowest was 4.16±0.96. In this study, when 360-degree hospitalization guide video was applied, there was a difference in anxiety and safety perception, and satisfaction was high. Based on the research results, various programs for guardian education can be developed and utilized in the future.
Background: In a previous study, we estimated exposure prevalence and the number of workers exposed to carcinogens by industry in Korea. The present study aimed to evaluate the optimal exposure intensity indicators of airborne lead exposure by comparing to blood lead measurements for the future development of the carcinogen exposure intensity database. Methods: Data concerning airborne lead measurements and blood lead levels were collected from nationwide occupational exposure databases, compiled between 2015 and 2016. Summary statistics, including the arithmetic mean (AM), geometric mean (GM), and 95th percentile level (X95) were calculated by industry both for airborne lead and blood lead measurements. Since many measurements were below the limits of detection (LODs), the simple replacement with half of the LOD and maximum likelihood estimation (MLE) methods were used for statistical analysis. For examining the optimal exposure indicator of airborne lead exposure, blood lead levels were used as reference data for subsequent rank correlation analyses. Results: A total of 19,637 airborne lead measurements and 32,848 blood lead measurements were used. In general, simple replacement showed a higher correlation than MLE. The results showed that AM and X95 using simple replacement could be used as optimal exposure intensity indicators, while X95 showed better correlations than AM in industries with 20 or more measurements. Conclusion: Our results showed that AM or X95 could be potential candidates for exposure intensity indicators in the Korean carcinogen exposure database. Especially, X95 is an optimal indicator where there are enough measurements to compute X95 values.

The study aims to assess composition, diversity and population indices of natural regeneration of woody species in Jebel El Gerrie forest reserve, Blue Nile State, Sudan. We conducted field work between December 2018 and January 2019. We used random sampling to collect vegetation data in the forest where we made a total of 90 circular sample plots (radius 17.84 m) and distributed them proportionally to the area of each of the four density-based vegetation classes of the forest i.e. high density (C1), medium density (C2), low density (C3) and crop land (C4). In each sample plot we identified all regenerating tree species and counted their regeneration frequencies. We calculated ecological metrics of regeneration frequency, density, abundance, richness, evenness, diversity and importance value index (IVI) and drew abundance rank curve. Results revealed that out of fifteen mature tree species present, natural regeneration of 8 species, which belong to 6 families, was observed. The relatively most frequently naturally regenerating and abundant species were Anogeissus leiocarpa and Combretum hartmannianum. Richness, evenness and diversity of regenerating species were 1.33, 0.82 and 1.7, respectively. One-way ANOVA (α=0.05) of mean regeneration densities disclosed that there were significant differences (F3,86=16.77, p=0.000) between C2 & C3 (p=0.000) and C2 & C4 (p=0.000). While regeneration of seven tree species were absent, two, two and four species were of good, poor and fair regeneration status, respectively. A comparison of mean density of natural regeneration with that of parent trees reflects a poor regeneration status of the forest. The study provides empirical results on the regeneration status of species and signifies the need for management interventions for species conservation and restoration, maintenance of biodiversity and sustainable production.
Objective: This study aimed to evaluate the zygomaticotemporal suture (ZTS) maturation, analyze the age distribution patterns of ZTS maturation stages, and investigate the relationship between ZTS and cervical vertebral maturation (CVM). Methods: A total of 261 patients who underwent cone-beam computed tomography (112 males, mean age, 13.1 ± 3.3 years; 149 females, mean age, 13.7 ± 3.1 years) were examined to evaluate the ZTS stages. The ZTS stages were defined based on a modified method from previous studies on zygomaticomaxillary sutures. Differences between groups and correlations between indicators were analyzed using the Spearman correlation test, intraclass coefficient of correlation (ICC), one-way analysis of variance and rank sum test. Statistical significance was set at p < 0.05. The diagnostic value of CVM stages in identifying ZTS maturation stages was evaluated using positive likelihood ratios (LRs). Results: A positive relationship was found between the ZTS and CVM stage (r = 0.747, ICC = 0.621, p < 0.01) and between the ZTS stage and chronological age (r = 0.727, ICC = 0.330, p < 0.01). Positive LRs > 10 were found for several cervical stages (CSs), including CS1 and CS2 for the diagnosis of stage B, CS1 to CS3 for the diagnosis of stages B and C, and CS6 for the diagnosis of stages D and E. Conclusions: The ZTS maturation stage may be more relevant to the CVM stage than to the chronological age. The CVM stages can be good indicators for clinical decisions regarding maxillary protraction, except for CS4 and CS5.
The study investigated the concentrations of Pb in soil, air and fruit of C. sinensis in selected landuse types in Port Harcourt Metropolis, Rivers State, Nigeria. Five fruits of C. sinensis were collected randomly in residential, commercial, industrial and natural forest (control). The weight, length and width of the C. sinensis fruits were measured. A total of three soil samples were collected around the C. sinensis trees where the fruits were collected into well labeled polythene bags and thereafter taken to laboratory for analysis. Pb concentrations in C. sinensis and soil samples were analysed using atomic absorption spectrophotometer (AAS). The concentration of Pb in the air was measured for 14 days using Aeroquel 500. The significant relationship between Pb concentration in the C. sinensis fruits, soil and air was determined using Spearman's rank correlation. Findings showed that the mean weight and width of C. sinensis fruits were highest in the residential landuse while the mean length of C. sinensis fruits was highest in the industrial landuse. However, the mean Pb concentration in the C. sinensis fruit was highest in the industrial landuse ($0.46{\pm}0.15mg\;kg^{-1}$), commercial landuse ($0.33{\pm}0.09mg\;kg^{-1}$) and the least was found in the natural forest ($0.25{\pm}0.06mg\;kg^{-1}$). The mean Pb concentration in the soil was highest in the industrial landuse ($0.177{\pm}0.16mg\;kg^{-1}$) and commercial landuse ($0.121{\pm}0.10mg\;kg^{-1}$). However, the mean Pb concentration in the air was highest in the industrial landuse ($0.85{\pm}0.09mg\;kg^{-1}$) and followed by commercial landuse ($0.30{\pm}0.17mg\;kg^{-1}$). The correlations between the Pb concentration in the C. sinensis fruit and soil (r=0.768, p<0.05) and air (r=0.642, p<0.05) were significant. The study concluded that the Pb concentration in the C. sinensis fruits was higher than the WHO standard; hence people should be discouraged to consume them, especially those from the industrial and commercial areas.
