Child labour is a disturbing issue for any society. It is attempted here in this article to develop an estimator to assess the numerical strength of this menace in Lahore division. A Horvitz and Thompson (1952) type of estimator is developed where weights are calculated on the basis of poverty and illiteracy to increase the sampling efficiency. Different characteristic features of this estimator, like its unbiasedness, variance, probability distribution, confidence intervals are also developed for its study from different angles.

In this study, a total of 350 households contained 700 individuals in Iganzo village were surveyed to study their literate and poverty levels and their impacts to conservation of the Mbeya Range Forest Reserve. The study included 350 women and 350 men. The majority of respondents were between the ages of 31-40 years old (53%), while the rest were between 41-50 years old (25%) and 21-30 years old (22%). The total income per day per household was calculated and averaged to 4,570 Tanzanian shillings that is equal to about 3 U.S. dollars. The average number of members per household was seven. It was reported that, there is a tremendous decrease in biodiversity composition of the reserve mainly due to poverty (80%) and ignorance (76%) of the people on the importance of the reserve. Other causes for this decrease were reported to be grazing of livestock in the reserve (23%), poor farming systems (68%), which resulted in soil erosion, encroachment (64%) through expansion of farms towards the reserve boundary and charcoal burning (34%). Respondents from Mbeya Urban Water Supply Authority and District Forest Office mentioned lack of funds (49%) and lack of experts (56%) as challenges that face the conservation of the reserve. It was revealed that 25% of respondents had never gone to school, 53% had primary level of education as their highest level of education, 20% had secondary education and 2% had first degree. The null hypothesis that poverty and illiteracy have a positive correlation to forest degradation was accepted based on these findings at a probability of p>0.85. Thus, it was concluded that poverty and illiteracy among Iganzo village residents are the main causes for the degradation of biodiversity in Mbeya Range Forest Reserve.

In an attempt to take Comprehensive nursing care the author tested cognitive function and psychiatric disturbance produced by normal adults. Mini-mental state and simple reaction time were tested and general health questionnaire was conducted two hundred subjects. The data were analyzed statistically and the results follow: 1. The score of mini-mental state of the elderly group was less significant than that of the younger group in the tests of cognitive dysfunction. The score of MMS of the female group, the illiteracy group less significant than that of other groups in the test of cogntive dysfunction. 2. Reaction time of the elderly group was slower than that of the younger group. Reaction time of the female group was slower than that of the male group. Reaction time of the illiteracy group was the slowest & the unskilled group was slower than that of the other groups. 3. As a result of the results of psychiatric disturbance the score of general health questionnaire of the elderly group was significantly higher than that of the younger group in the tests of psychiatric disturbance. The test of psychiatric disturbance sho-wed that the score of general health questionnaire of the female group was significantly higher than that of the male group in the tests of psychiatric disturbance. The illiteracy group was the highest in the psychiatric disturbance among other groups and the unskilled group was significantly higher than the other groups. 4. Education had higher correlation to mini-men-tat state, while age negative correlation in comparison with other variables age had higher correlation to reaction time, while education had negative correlation in comparison with other variables. Sex had low correlation in these tests.

Purpose: This study was to estimate the prevalence of dementia in order to estimate the associations of dementia with its risk factors in the community elderly. Methods: The multistage random cluster sampling method was used to select the subjects. The response rate was 94.3%. For the 1st stage screening survey, the Korean-version Mini-Mental State Examination (K-MMSE) and the Bathel Index of activities of daily living (ADL) and instrumental activities of daily living (IADL) were used as primary screening tools. At the 2nd stage. diagnoses were confirmed according to the Clinical Dementia Rating Scale (CBR) and Computer Tomogram (CT). Results: Age-sex adjusted prevalence (%) [95% CI] of dementia was 6.25% [4.47-7.83] (male 4.21% [2.40-6.02]; female 8.28% [5.71-10.85]). Four statistically significant risk factors of the dementia were identified: age 70-74 (OR=1.367), age 75-79 (OR=1.712), age 80-84 (OR=2.465), age 85 over (OR=7.363) illiteracy (OR=3.827); unconsciousness after head injury (OR=3.383), and no exercise (OR=2.188). Hosmer and Lemeshow goodness-of-fit index of dementia risk model was E (legit of dementia)= -4.337+$0.312^*Age(70{\sim}74)+0.538^*Age(75{\sim}79)+0.902^*Age(80{\sim}84)+1.996^*Age$(85over)+$1.342^*$Illiteracy+$1.219^*$Unconsciousness after head trauma+$0.783^*$No exercise. We confirmed that the overall prevalence of dementia in adults aged 65 and older was 94.3%. The risk factors of dementia were explained by age, illiteracy unconsciousness after head trauma and no exercise. Conclusion: These data have been used to estimate the incidence of dementia in elderly community population and to manage the possible role of risk factors as predictors of dementia.

Objectives: This study aims to identify the influencing factors of using postnatal care among illiteracy women who live in the Democratic Republic of Congo. Methods: Household survey was done from February 1 to 8, 2013 in the Kwango district of Democratic Republic of Congo, and 400 childbearing women who has under 5 years old children and pregnant women was randomly selected and answered through the interview with a questionnaire. For analysis the data, ${\chi}^2$ test and logistic regression analysis were used. Results: Woman who can read, write and mathematical calculation was 195 (47.4%) of total 411 answers and 161 (39.2%) used postnatal care for their latest pregnancy. Age at first marriage (${\chi}^2=18.481$, p<.001), religions (${\chi}^2=11.165$, p=.011), languages (${\chi}^2=35.586$, p<.001), the experience of children death (${\chi}^2=16.507$, p<.001), antenatal care over 4 times (${\chi}^2=15.315$, p<.001), postnatal care (${\chi}^2=15.558$, p<.001) is significantly different from literacy level. Among illiterate women group, who are protestant (OR=.330), using Lingala (OR=.128), took elementary education (OR=.223) and farmer (OR=.040), used less postnatal care. Conclusions: For increasing usage of postnatal care among illiterate women, new approach method should be considered such as a visual communication method and a community health workers' training program for giving an outreach service to pregnant women care.

Steady-state visual evoked potential-based brain-computer interface (SSVEP-BCI) is one of the promising systems that can serve as an alternative input device due to its stable and fast performance. However, one of the major bottlenecks is that some individuals exhibit no or very low SSVEP responses to flickering stimulation, known as SSVEP illiteracy, resulting in low performance on SSVEP-BCIs. However, a lengthy duration is required to enhance multiple SSVEP responses using traditional single-frequency transcranial alternating current stimulation (tACS). This research proposes a novel approach using dual-frequency tACS (df-tACS) to potentially enhance SSVEP by targeting the two frequencies with the lowest signal-to-noise ratio (SNR) for each participant. Seven participants (five males, average age: 24.42) were exposed to flickering checkerboard stimuli at six frequencies to determine the weakest SNR frequencies. These frequencies were then simultaneously stimulated using df-tACS for 20 minutes, and the experiment was repeated to evaluate changes in SSVEP responses. The results showed that df-tACS effectively enhances the SNR at each targeted frequency, suggesting it can selectively improve target frequency responses. The study supports df-tACS as a more efficient solution for SSVEP illiteracy, proposing further exploration into multi-frequency tACS that could stimulate more than two frequencies, thereby expanding the potential of SSVEP-BCIs.

The purpose of this study is to investigate factors which can lead small buyers to participate in a Reverse Aggregation Electronic Market (RAEM). Five factors including search, selection, price, delivery, and Internet literacy were selected as possible factors which are expected to influence small buyers' participation in a RAEM. This paper focused on a RAEM of the Korean automotive industry in which the third party aggregator formed a group of small automobile repair shops (ARS) and amassed buying power for them by building a buyer' oriented electronic market (EM). Survey data were collected from small ARS in South Korea. The results of the empirical analysis indicated that fast delivery and support for Internet illiteracy are potential incentives that could influence buyers' decisions to join a RAEM.

The paper brings to question how image as a medium is becoming a replacement for traditional letters in the modern culture. Reflection the importance of image in the context of modern society with the changes in the values of communication. The importance of letters in its traditional format as a book that signified not only the method of communication but also power for those who governed during the days of illiteracy in the past has changed, in the beginning with the development of printing and today with movies etc. that supply endless images instead of words as a means of communication. The images are the next generation in the method of communication and can be noted from the earliest civilizations such as Egypt where the method of communication was not words but drawings that depicted specific significations. The use of images for communication purposes in light of this fact suggests that images was being used before words in societies and its communicative values greater than that of words.
